Stabilizing Dog Populations and Improving Animal and Public Health Through a Participatory Approach in Indigenous Communities

Access to veterinary care: evaluating working definitions, barriers, and implications for animal welfare

Humans have a moral obligation to meet the physical and mental needs of the animals in their care. This requires access to resources such as veterinary care, which is integral to achieving animal welfare. However, "access" to veterinary care is not always homogenous across communities and currently lacks a consistent definition. The objectives of this scoping review were to (1) understand how "access" to veterinary care has been defined in the literature, (2) map a broad list of potential barriers that may influence access to veterinary care, and (3) identify how access to care impacts the welfare of companion and livestock animals. The literature search yielded a total of 1,044 publications, 77 of which were relevant to our inclusion criteria, and were published between 2002 and 2022. Studies were most frequently conducted in the United States (n = 17) and Canada (n = 11). Publications defining access to veterinary care (n = 10) or discussing its impacts on animal welfare (n = 13) were minimal. However, barriers to accessing veterinary care were thoroughly discussed in the literature (n = 69) and were categorized into ten themes according to common challenges and keywords, with financial limitations (n = 57), geographic location (n = 35), and limited personnel/equipment (n = 32) being the most frequently reported. The results of this scoping review informed our proposed definition of access to veterinary care. Additionally, our findings identified a need to further investigate several understudied barriers relating to access to care (i.e., veterinarian-client relationship, client identity) and to better understand how they potentially affect animal welfare outcomes.

Barriers and opportunities for improving dog bite prevention and dog management practices in northern Indigenous communities

Globally, people living in northern Indigenous communities are at higher risk of dog bites than the rest of the population living in North America, with annual incidence ranging from 0.61 to 59.6/10,000 inhabitants. Considering that rabies is endemic in wild canid populations in certain regions of the Arctic, the prevention of dog bites and the management of dog populations are of crucial importance for public health in these contexts. Most northern communities lack access to veterinary services, mainly due to their remote geographical location and to limited financial resources. Currently, northern Indigenous communities are using different approaches and strategies to prevent dog bites and manage dog populations, but the effectiveness of these approaches sometimes lacks evidence, and their low acceptability may affect their implementation. This study aims to describe (1) the current access and uses of veterinary services, and (2) the perceived barriers and opportunities related to dog population management practices currently implemented, or that could be implemented, in a Naskapi community and an Innu community located in northern Quebec (Canada). Quantitative data were collected through a survey to inhabitants on veterinary services (n = 122). Qualitative data were collected using individual interviews to inhabitants and health professionals to describe how dog population management measures were perceived, and to identify barriers and opportunities related to their implementation (n = 37). Descriptive and inferential analysis (quantitative data) and thematic analysis (qualitative data) were performed. Results show that the two main measures implemented at the time of the study - dog culling and short-duration veterinary clinics - were not perceived as fully acceptable and sustainable. Reinforcing access to veterinary services and other dog-related services, such as shelters and training programs on dogs, was identified as a need to improve dog bites prevention and dog population management in remote Indigenous communities. The implementation of animal health measures should be decided by concerned Indigenous communities to follow decolonial practices. It includes ensuring informed consent of dog owners, improving communication before, during and after interventions, separating veterinary services from rehoming and, most importantly giving back to Indigenous communities the complete leadership over animal health in their communities.

Capturing free-roaming dogs for sterilisation: A multi-site study in Goa, India

Sterilisation and rabies vaccination programs seek to manage free-roaming domestic dog (Canis familiaris) populations with the aim to reduce inter-species disease transmission and conflicts. As effective, permanent, remotely-administered options are not yet available for sterilisation, and oral vaccination is not yet commonly used; free-roaming dogs are typically captured for these interventions. There is a paucity of information describing how dog capture rates change over time within defined areas following repeated capture efforts. This data is needed to allow efficient dog capture programmes to be developed. Using spatial co-ordinates of dog capture, we characterise where dogs are more likely to be captured in six catch-sterilise-release campaigns, in Goa state, India. Combining capture numbers with population survey data collected in five sites, we document the increasing difficulty of catching entire (non-sterilised) dogs as sterilisation coverage increases and demonstrate how this leads to increased unit costs. Accounting for the extra resources required to capture dogs when sterilisation coverage is high will improve estimation of the resources required to manage free-roaming dog populations and assist in planning the most efficient intervention strategies.

Mandan, Hidatsa, and Arikara Nation Perspectives on Rez Dogs on the Fort Berthold Reservation in North Dakota, U.S.A

The research on the relationships between free-roaming dogs, also referred to as reservation dogs or rez dogs, and Indigenous communities is extremely limited. This study aimed to document the cultural significance of rez dogs, challenges related to rez dogs, and community-specific solutions for rez dog issues affecting community health and safety from members of the Mandan, Hidatsa, and Arikara (MHA) Nation, also referred to as the Three Affiliated Tribes (TAT), who live on the Fort Berthold reservation in North Dakota, U.S.A. One hour semi-structured interviews with 14 community members of the MHA Nation were conducted in 2016. The interviews were analyzed via systematic and inductive coding using Gadamer's hermeneutical phenomenology. The primary intervention areas described by the participants included: culturally relevant information sharing, improved animal control policies and practices, and improved access to veterinary care and other animal services.

Evolution and expansion of the One Health approach to promote sustainable and resilient health and well-being: A call to action

One Health is a transdisciplinary approach used to address complex concerns related to human, animal, plant, and ecosystem health. One Health frameworks and operational tools are available to support countries and communities, particularly for the prevention and control of zoonotic diseases and antimicrobial resistance and the protection of food safety. However, One Health has yet to be implemented in a manner that fully considers the complexities and interconnectedness of the diverse influences that have impacts at a larger system level. This lack of consideration can undermine the sustainability of any positive outcomes. To ensure the One Health approach can function effectively within the new global context of converging and escalating health, social, economic, and ecological crises, it must evolve and expand in three overlapping dimensions: (1) Scope: the partners, knowledge, and knowledge systems included, (2) Approach: the techniques, methodologies, and scholarship considered, and (3) Worldview inclusivity: the interweaving of other worldviews together with the mainstream scientific worldview that currently predominates. Diverse partners and knowledge from outside the mainstream health and scientific sectors, including Indigenous peoples and representatives of local communities, and traditionally generated knowledge, must be included. These systems of knowledge can then be braided together with mainstream science to comprise a holistic framework for decision-making. Scholarship and methodologies being applied in other fields and contexts to solve complex challenges and manage uncertainty, such as collaborative governance, social-ecologic systems theory, and complexity science, must be recognized and incorporated. The spectrum of considered worldviews must also expand to authentically integrate the expanded scope and approach into action and sustainable impact. By increasing community and social engagement and by recognizing and entwining different worldviews, the plurality of disciplines, and traditional and scientific ways of knowing to address community concerns in the contexts in which they exist, we can ensure that One Health remains effective and true to its paradigm in our rapidly changing and complex world.

Student Veterinarian Perceptions of Community-Based Primary Care Veterinary Clinics in Indigenous Communities in Southern Ontario, Canada

Community-based primary care veterinary clinics represent an opportunity to benefit multiple populations. Student veterinarians are afforded the opportunity to build technical and non-technical professional skills, while underserved communities are provided with access to companion animal care. The Ontario Veterinary College (OVC), as with many other veterinary colleges across Canada and the United States, has hosted community-based primary care veterinary clinics, including in local Indigenous communities. As these clinics continue and grow, it is critical to evaluate their operation to ensure that they align with community goals and values, adequately support student learning, and do not perpetuate racism and implicit bias. The objective of this study was to explore the perceptions of student veterinarians who had volunteered at community-based primary care veterinary clinics in First Nations communities in southern Ontario, Canada. We used an online survey that consisted of multiple choice and short answer questions focused on motivating factors for involvement, supports available before and during the clinics, exposure to Indigenous cultures, and the challenges and rewards associated with volunteering. Forty-one student veterinarians from OVC completed the survey in January 2020. Most students were motivated to volunteer to make a positive difference in the lives of people and animals and improve their clinical skills. In general, respondents felt adequately prepared for and supported during their experiences but did recommend additional pre-departure instructions on roles and responsibilities. Participants were ambivalent as to whether they had learned about Indigenous culture, with several strongly recommending more cultural sensitivity training. Most students found their experiences rewarding because of the gratitude expressed by clients and the feeling that they had made a difference. We reflect on the potential benefits and challenges of community-based primary care veterinary clinics in light of student responses.

Knowledge, attitudes, and practices regarding dogs and dog bites in Indigenous northern communities: A mixed methods study

Introduction

The singular relationship developed over the years between northern Indigenous peoples and dogs has been profoundly changed through historical trauma, settlements and increased use of snowmobiles. Issues related to dogs have become increasingly complex and worrisome with the endemic presence of the rabies virus among Arctic fox populations, and given the fact that northern Indigenous peoples may have a higher risk of dog bites than the general population. This study aimed to investigate factors related to the risk of dog bites in Naskapi and Innu communities located in northern Quebec (Canada) by (1) describing the knowledge, attitudes and practices (KAP) regarding dogs and dog bites in these communities, and (2) analyzing experiences of inhabitants and health professionals with regard to dog bites and their management.

Methods

A mixed methods study design that combined an observational cross-sectional survey and individual interviews was used. The survey collected data on KAP regarding dogs and dog bites among 122 respondents. Individual interviews (n = 37) were then conducted with victims of dog bites, owners of dogs that have bitten a person before, and health professionals. Descriptive and inferential analysis (quantitative data) and thematic analysis (qualitative data) were performed.

Results and discussion

Results highlighted that 21% of respondents have had a dog bite in their lifetime. Most respondents were not aware of the risk of contracting rabies following a dog bite, although rabies risk perception was associated with risk perception of dogs (linear regression: coefficient = 0.69, 95% CI = 0.36-1.02). The odds of being more knowledgeable on rabies were higher (logistic regression: OR = 2.92, 95% CI = 1.07-7.98) among young adults. Dogs were perceived as both threats and protectors by community members. When the fear of dogs was present, it affected the quality of life of some inhabitants. There was confusion about responsibilities in the management of biting dogs, although protocols to follow after a bite were clear for health care professionals. This study revealed a lack of awareness and knowledge about dog bites and rabies risks in both communities. Results provide important knowledge for the development of interventions adapted to northern Indigenous communities.

Study of dog control strategies

OBJECTIVES

(1) To explore the relationship between regionally implemented dog control strategies and dog bite injuries (DBIs) and (2) to evaluate current implementation of dog control strategies.

METHODS

Observational study using a nationwide online survey of territorial authorities (TAs). Domains of interest included complaints for attacks on people, dog population, primary and secondary prevention strategies, resourcing and perspectives of current strategies. Quantitative variables were compared with DBI Accident Compensation Corporation (ACC) claims by region from 2014 to 2018.

RESULTS

Two-thirds of TAs (70%; n=47/67) responded to the survey. No clear relationship was observed between DBIs and: registered dog population, proportion sterilisations or microchipping, classifications due to dog behaviour, or existing limited resourcing. Legislated breeds and infringements for failure to control a dog or non-registration were higher in areas with greater DBIs. Educational messages varied widely and were predominantly victim directed (67%; n=71/106). Complaints for dog attacks on people were lower than DBIs in most areas, with no formal cross-agency notification policies. Few prosecutions or dog destruction orders were made.

CONCLUSIONS

Regional inequity in DBIs could not be explained by differences in the registered dog population or dog control strategies. Minimal and inequitable resourcing exists to implement current dog control strategies and provide owner-directed education. Gaps in legislation include environmental barrier requirements for all dogs (leash/muzzle use, adequate fencing), notification of incidents and child protection. Partnership with the Indigenous community (Māori) and other community groups will be required to implement these measures successfully.

Human social conditions predict the risk of exposure to zoonotic parasites in companion animals in East and Southeast Asia

Background

A recent dramatic surge in pet ownership has been observed across metropolitan areas in Asia. To date, there is a dearth of information on the risk associated with pet ownership for the transmission of parasites on a large scale in Asia, despite this continent giving rise to the largest burden of zoonotic infections worldwide.

Methods

We explored the nature and extent of zoonotic internal (endo-) and external (ecto-) parasites and arthropod-borne pathogens in 2381 client-owned dogs and cats living in metropolitan areas of eight countries in East and Southeast Asia using reliable diagnostic tests and then undertook extensive statistical analyses to define predictors of exposure to zoonotic pathogens.

Results

The estimated ORs for overall parasite infections are 1.35 [95% CIs 1.07;1.71] in young animals and 4.10 [1.50;11.2] in the animal group older than 15 years as compared with adult animals, 0.61 [0.48;0.77] in neutered animals as compared to unneutered animals, 0.36 [0.26;0.50] in animals living in urban areas as compared with rural areas, 1.14 [1.08;1.21] for each 1 °C increase of annual mean temperature which varies from 12.0 to 28.0 °C, and 0.86 [0.78;0.95] for each year of life expectancy which varies from 70.9 to 83.3 years.

Conclusions

Here we highlight the influence of human life expectancy and the neutering status of the animals, which reflect increased living standards through access to education and human and veterinary health care, to be both strongly associated with exposure to zoonotic parasites. An integrated approach of local and international authorities to implement and manage educational programs will be crucial for the control of zoonotic infections of companion animals in Asia.

Parasites live on or inside animals or humans and can cause disease. Companion animals (pets) with parasites present a potential risk to the health of their owners, as certain kinds of parasites (known as zoonotic parasites) can affect both animal and human health. Here, we investigated whether human social conditions are associated with zoonotic parasite infections in companion animals in East and Southeast Asia. We found that higher human life expectancy and neutering of the companion animals were associated with fewer zoonotic parasite infections in the animals. These findings highlight the need for an enhanced commitment of local authorities to establish prevention campaigns, including education programs, against zoonotic pathogens. These measures will play a crucial role in alleviating the impact of these diseases in companion animals and humans in Asia.

Colella, Wongnak et al. test pet dogs and cats from metropolitan areas of eight countries in East and Southeast Asia for zoonotic parasites. The authors identify factors associated with potential exposure to zoonotic parasites, including animal characteristics and human living conditions.

Systematic review of dog bite prevention strategies

BACKGROUND

The prevention of dog bites is an increasingly important public health topic, as the incidence of serious injury continues to rise.

OBJECTIVES

To evaluate the effectiveness of interventions to prevent dog bites and aggression.

METHODS

Online databases were searched (PubMed, Cochrane Library, Embase and Google Scholar), using the search terms: dog/s, canine, canis, kuri, bite/s, bitten, aggression, attack, death, fatal, mortality, injury/ies, prevention, intervention, for studies between 1960 and 2021. All study designs were considered. Outcomes of interest were the incidence of dog bites or dog aggression. Non-English studies, and those without full-text access were excluded.

RESULTS

Forty-three studies met the review criteria, including 15 observational and 27 interventional studies. Fifteen studies investigating dog-control legislation, including leash laws, stray dog control and infringements indicated this can reduce dog bite rates. Breed-specific legislation had less of an effect. Six studies investigating sterilisation, showed while this may reduce dog bites through a reduction in the dog population, the effect on dog aggression was unclear. An alcohol reduction programme showed a significant reduction in dog bite rates in one study. Seven studies assessing educational approaches found that intensive adult-directed education may be effective, with one study showing child-directed education was not effective. Eight studies on dog training (two police-dog related), and six evaluating dog medication or diet were generally low quality and inconclusive.

CONCLUSIONS

Multiple strategies including effective engagement with indigenous communities and organisations will be required to reduce dog-bites and other incidents involving dog aggression. This review provides some evidence that legislated dog control strategies reduce dog bite rates. Available evidence suggests greater restrictions should be made for all dogs, rather than based on breed alone. Due to a burden of child injury, protection of children should be a focus of legislation and further investigations. Prevention strategies in children require redirection away from a focus on child-directed education and future research should investigate the effectiveness of engineering barriers and reporting strategies.

Occurrence and Risk Factors of Dog Bites in Northern Indigenous Communities: A Scoping Review

The relationship between northern Indigenous people and dogs has evolved over the past years alongside events such as colonization, settlement, proliferation of snowmobiling and other socio-cultural and environmental changes. These changes have had negative impacts on this relationship, and with the endemic presence of arctic fox rabies, dog bites have become an important public health burden. The objective of this study was to synthesize the state of knowledge regarding the occurrence of dog bites and associated risk factors in the specific context of northern Indigenous communities. A scoping review was conducted in seven bibliographic databases, from June 2018 to May 2020. From this search, 257 original studies were identified and eight papers were included for final analysis. Annual occurrence of dog bites in northern Indigenous communities ranged from 0.61 to 59.6/10,000 inhabitants. Dog bites affected 27–62.9% of the population in those regions during their lifetime. Very few studies compared the occurrence of dog bites between people living in northern communities with other populations or settings, but available evidence suggests that Indigenous people living in northern communities are at higher risk of dog bites than the rest of the population. Several individual and environmental risk factors were identified in the selected studies, although the strength of evidence varied significantly. Age (children) and gender (male) were well documented individual risk factors. Other factors, such as organizational barriers to dog management and lack of access to veterinary services, were identified and discussed by several authors. The results of this study support concerns about the higher risk of bites in northern Indigenous communities, and underscore the urgent need for more research into the contextual and environmental factors that impact the mitigation of these risks.

Zoonoses and the Aboriginal and Torres Strait Islander population: A One Health scoping review

With limited access to animal health services, and high disease burdens among domesticated animals, Aboriginal and Torres Strait Islander communities in Australia face higher risk of disease including zoonoses. However, we lack understanding of the contribution of often preventable zoonoses to the health of these communities, which would enable us to enhance public health strategies and improve health outcomes. We conducted a scoping review to identify the current state of evidence on zoonoses in the Aboriginal and Torres Strait Islander population. We examined the size, scope and characteristics of the evidence base and analysed the zoonoses detected in the studies within a One Health framework. We identified 18 studies that detected 22 zoonotic pathogens in animals, people, and the environment, with most studies detecting pathogens in a single One Health sector and no studies investigating pathogens in all three sectors. Findings indicate that despite the strong conceptual foundations of One Health throughout the evidence base, evidence is lacking in application of this concept. There is a need to undertake further research that prioritises Aboriginal and Torres Strait Islander leadership, considers the contribution of human, animal and environmental health factors, and investigates the prevalence and impact of zoonoses in communities through a One Health approach.

Current characteristics of animal rabies cases in Thailand and relevant risk factors identified by a spatial modeling approach

The situation of human rabies in Thailand has gradually declined over the past four decades. However, the number of animal rabies cases has slightly increased in the last ten years. This study thus aimed to describe the characteristics of animal rabies between 2017 and 2018 in Thailand in which the prevalence was fairly high and to quantify the association between monthly rabies occurrences and explainable variables using the generalized additive models (GAMs) to predict the spatial risk areas for rabies spread. Our results indicate that the majority of animals affected by rabies in Thailand are dogs. Most of the affected dogs were owned, free or semi-free roaming, and unvaccinated. Clusters of rabies were highly distributed in the northeast, followed by the central and the south of the country. Temporally, the number of cases gradually increased after June and reached a peak in January. Based on our spatial models, human and cattle population density as well as the spatio-temporal history of rabies occurrences, and the distances from the cases to the secondary roads and country borders are identified as the risk factors. Our predictive maps are applicable for strengthening the surveillance system in high-risk areas. Nevertheless, the identified risk factors should be rigorously considered and integrated into the strategic plans for the prevention and control of animal rabies in Thailand.

Knowledge, attitudes and practices regarding to rabies and its prevention and control among bite victims by suspected rabid animals in China

Rabies is a major public health problem and the incidence of suspected rabid animal bites remains high in China. This study aimed to assess the knowledge, attitudes, and practices (KAP) about rabies of bite victims in Wuhan, China. A cross-sectional study was conducted among 1015 bite victims visiting rabies prevention clinics. We performed a face-to-face interview to investigate the rabies KAP of these victims using a self-designed questionnaire. Factors associated with the KAP were evaluated using logistic regression models. Only 56.85% of respondents knew that rabies is infectious. More than 20% of respondents thought that it is not necessary to vaccinate dogs and cats against rabies usually. About 70% of participants stated that they never need to be reminded to vaccinate when they were bitten. Lower education level (odds ratio [OR] = 3.77, 95% confidence interval [CI]: 2.65-5.38 for secondary school or less and OR = 1.74, 95% CI: 1.28-2.38 for high school or vocational school, p-trend<0.0001) was independently associated with poor knowledge of rabies. Respondents who had experienced two or more times of animal bites (OR = 0.62, 95% CI: 0.39-0.97) were inclined to have appropriate attitudes about rabies prevention and control. Older respondents were more likely to show proper behaviors towards rabies prevention and control (OR = 0.44, 95% CI: 0.33-0.58 for age group 31-60 and OR = 0.34, 95% CI: 0.21-0.54 for age group >60, p-trend <0.0001). The level of rabies KAP among bite victims in China was suboptimal. It is necessary to conduct interventions focusing on improving public awareness of rabies and ameliorating behaviors of rabies post-exposure prophylaxis.

One Health in Indigenous Communities: A Critical Review of the Evidence

Indigenous populations around the world face disproportionately high rates of disease related to the environment and animals. One Health is a concept that has been used effectively to understand and address these health risks. One Health refers to the relationships and interdependencies between animal, human, and environmental health and is an emerging research field that aligns with indigenous views of health. To understand the applicability of One Health in indigenous communities, a critical review was undertaken to investigate evidence of One Health research in indigenous communities internationally, assess the strength of evidence, and understand what gaps are present. This review included the appraisal of twenty-four studies based in five regions: Canada, Africa, Australia, South America, and Central America. The review found that there is a need for studies of high strength, with rigorous methods, local leadership, and active involvement of indigenous viewpoints, to be undertaken in indigenous communities internationally that focus on One Health. It highlights the need to further consider indigenous viewpoints in research to reduce limitations, increase effectiveness of findings, consider appropriateness of recommendations, and benefit communities.

Free-ranging dogs as a potential threat to Iranian mammals

Free-ranging domestic dogs Canis familiaris threaten wildlife species through predation, hybridization, competition for resources, and by contributing to the transmission of pathogens. The impacts of predation may be problematic, but in many regions the interactions of free-ranging dogs and wildlife are poorly studied. To determine the extent of the impacts of attacks by free-ranging dogs on Iranian mammals, we reviewed nearly 2 decades of social and traditional media reports and the scientific literature to gather data from across the country. We identified 160 free-ranging dog attacks (79 from academic articles, 14 from social media, and 67 from a variety of news websites) from 22 of the country's 31 provinces. Attacks by dogs were reported on 17 species, including nine Carnivora, six Artiodactyla, one Rodentia, and one Lagomorpha species. Most of the reported attacks on carnivores were on felids, including the Asiatic cheetah Acinonyx jubatus (n = 19), Eurasian lynx Lynx lynx (n = 18), caracal Caracal caracal (n = 10) and Pallas's cat Otocolobus manul (n = 8). Attacks on Artiodactyla were primarily reported for goitered gazelle Gazella subgutturosa (n = 47). Most of these attacks occurred within or adjacent to protected areas (n = 116, 73%), suggesting that free-ranging dogs are one of the most important human-associated threats to wildlife species even in protected landscapes. The impact of free-ranging dogs may be hampering conservation, and therefore we suggest some practical policy guidance for managing the impacts of free-ranging dogs on threatened species.

11 years of regular access to subsidized veterinary services is associated with improved dog health and welfare in remote northern communities

Access to veterinary services can have positive impacts on animal health and welfare, and on human mental and physical health and well-being; however, many communities worldwide lack access to such services. At their request, the 5 communities of the Sahtu Settlement Area, Northwest Territories, Canada, have received annual access to preventive veterinary services through the University of Calgary's Northern Community Health Rotation since 2008. To determine the reach of the program, we conducted a dog census in 2017. We then conducted a chart review of 11 years of dog medical records from 2008 to 2018 to evaluate how the reach of the program, the uptake of veterinary services, and dog population demographics, health and welfare measures changed over the duration of the program. In the chart review, we used either multi-level logistic regression or generalized linear models, to determine how seven variables, including age, sex, breed, body condition, deworming, vaccination, and sterilization status upon clinic entry, changed over the course of program delivery. Our results suggest that program reach, veterinary service uptake, and dog demographic, health and welfare measures improved over time. We observed high rabies vaccination coverage in some communities (48 %-83 % of the dog population) and moderate overall sterilization status (25 %-56 % of the dog population) with female dog sterilization more common than male (75 % of dogs leaving the 2017 clinics, compared to 43 %). Several dog demographic, health, and welfare measures, including age, body condition, and vaccination, deworming, and sterilization status, were significantly better in later years of the program (all p < 0.001). Differences among communities, both in dog population numbers from the 2017 census (40-89 dogs) and in the uptake of veterinary services in 2017 (48 %-83 % of the dog population), were notable. Vaccination uptake was directly related to clinic attendance, but sterilization was impacted by additional factors, including community members' acceptance of the procedure. Some unintended consequences were noted, however, including the potential effect of sterilization on the availability of traditional dog breeds in the communities. Overall, our study findings demonstrate that subsidized veterinary services provided over a regular and extended period of time benefit animal population demographics, health and welfare, and could have positive impacts on human well-being. The framework of community collaboration and long-term commitment developed through this program serves as a model for achieving common health goals among communities in need and veterinary service providers.

One Health and reconciliation: media portrayals of dogs and Indigenous communities in Canada

This qualitative media analysis explores how the Canadian Broadcasting Corporation (CBC) portrayed 'dog problems' and their solutions in Indigenous communities in Canada from 2008 through 2018. We apply a One Health framework to demonstrate how human, animal, and the socio-environmental health are interconnected, which aligns more explicitly with Indigenous worldviews. Through this analysis, we respond to the Truth and Reconciliation Commission (TRC) of Canada's Calls to Action, specifically Action 19 (health inequity) and Action 84 (media). We found that the CBC portrayed dogs as "strays" and focused mainly on the removal of dogs, whether rehoming by animal rescue groups or through culling, and that rescue groups were portrayed as 'animal lovers'. Meanwhile, journalists sometimes mentioned the lack of policies to support community-driven dog population control and veterinary services, but these policy deficits did not receive emphasis. The CBC coverage did not highlight systemic injustices that can impact dog health and welfare in Indigenous communities. This media analysis outlines ways forward for reconciliation with Indigenous communities when the media reports on dogs; we recommend journalists (i) focus on lack of veterinary services in communities and the impacts rather than the removal of dogs, (ii) discuss broader systemic structures and policies that limit access to veterinary services in Indigenous communities and (iii) how such resource constraints impact human and animal health.

Examining the concept of One Health for indigenous communities: A systematic review

Purpose

This paper examines whether the usage of the concept of One Health in Canada-based research aligns with traditional Indigenous notions of health and wellness.

Methods

A comprehensive search of the literature was conducted using primary databases, including Scholars Portal, ProQuest Social Science, Sociological Abstracts (ProQuest), OVID Healthstar, Embase, Medline, Pubmed and Google Scholar. Papers discussing One Health and Indigenous Health were selected and analyzed through Nvivo12 to generate common themes across the studies.

Results

The analysis identified three major themes that focused on One Health as it relates to climate change, zoonosis, and social relationships between humans and animals. Climate change was seen to have affected the environmental health of Northern latitude areas where many Indigenous communities reside. Infectious diseases within Indigenous communities were a frequent topic of study and indicated that infections transmitted by dogs are likely to be addressed with One Health interventions. One Health interventions are likely to equally address the health of humans, animals, and the environment.

Conclusions

No significant connection between One Health and Indigenous knowledges was established in the analyzed articles. Articles discussed One Health as it pertains to epidemiological surveillance and research. The implications of utilizing One Health towards Indigenous Peoples and culture were not explicitly addressed.

A Mapping Study of Veterinary Literature on Perceptions and Attitudes of Female Canine Spaying

This is a mapping study conducted to evaluate the characteristics of where content that engages in perspectives or attitudes on female dog spaying is published. Three databases, CAB Direct, PubMed, and Scopus, were systematically searched. There were 84 out of 642 papers identified and screened for relevance on attitudes or perceptions on female canine spaying. These 84 articles were then examined for recurring authors, institutional representation, and publisher information. Additionally, information regarding the population being addressed, veterinarian or client, was noted with most literature addressing the veterinary perspective. Many important articles were published in a wide array of journals from many countries, which suggests the importance of not only browsing journals but also searching for relevant literature in databases like CAB Abstracts and MEDLINE.

Evaluating Impacts of a One Health Approach to Companion Animal Health and Management in a Remote Aboriginal Community in the Northern Territory, Australia

Simple Summary

Many remote Australian Aboriginal communities face barriers in accessing animal health care for their pets. A community that faces these barriers implemented a community-driven program with the objective of improving animal health and population management. The program was evaluated by comparing the percentage of animals desexed, the body and hair condition of dogs, and the presentations at the health clinic for dog bites before versus after 12 months of program implementation. Results show improved animal health measures and no measurable change in human presentations for dog bites. This program, with One Health considerations, could be suitable for other communities facing similar animal health care barriers.

Abstract

This study evaluated a community-driven animal health and management program in the remote community of Wadeye, Northern Territory. This evaluation used a pre-post design to assess changes in animal and human health outcomes over a 12-month period of program implementation, from June 2018 to June 2019. The evaluation assessed the program by comparing animal health outcomes before versus one year after program implementation and comparing human health outcomes before versus during the first 12 months of the program. Outcome measures included the desexing status of dogs and cats, body condition and hair score of dogs, and rates of people presenting to the health clinic for a dog bite. Animal health outcomes significantly improved after program implementation. From pre to post program, there was a 77% increase in the prevalence of good body condition score among dogs and a 9% increase in the prevalence of good hair score among dogs, and the prevalence of desexed dogs and cats more than doubled. There was no significant change in the number of people presenting to the health clinic for a dog bite. Consideration on how to further incorporate human and environmental health aspects into the program could be useful for future One Health programs.

Evaluating the role of surgical sterilisation in canine rabies control: A systematic review of impact and outcomes

Current recommendations for the elimination of canine-mediated human rabies focus on mass dog vaccination as the most feasible and cost-effective strategy. However, attempts to control rabies are often combined with canine surgical sterilisation programmes. The added value of sterilisation is widely debated. A systematic review was undertaken to compare the outcomes and impact of vaccination and sterilisation programmes with vaccination only programmes. A systematic search of three electronic databases (CAB Abstracts, Medline and Global Health) and grey literature was performed. From 8696 abstracts found, 5554 unique studies were identified, and 16 studies met the inclusion criteria. Eight described vaccination only programmes and eight described vaccination and sterilisation programmes. Indicators of impact measured were dog bites and/or doses of post-exposure prophylaxis administered; numbers of dog and/or human rabies cases; dog population demographic changes; changes in health and welfare of dogs, and indicators related to human behaviour change. The studies were contextually very diverse, programmes being implemented were complex, and there was variation in measurement and reporting of key indicators. Therefore, it was difficult to compare the two types of intervention, and impossible to make an evaluation of the role of sterilisation, using this evidence. Given the large number of vaccination and sterilisation programmes conducted globally, the lack of studies available for review highlights a gap in data collection or reporting, essential for impact assessment. There are several knowledge gaps concerning the impact of the sterilisation component alone, as well as subsequent effects on rabies transmission and control. Prospective studies comparing the outcomes and impact of the two interventions would be required in order to establish any additional contribution of sterilisation, as well as the underlying mechanisms driving any changes. In the absence of such evidence, the priority for rabies control objectives should be implementation of mass vaccination, as currently recommended by the World Health Organisation.

One Health promotion and the politics of dog management in remote, northern Australian communities

Community perspectives are rarely sought or integrated into dog management policy and practice. Dog management in remote communities in Australia has focused on reducing the number of dogs, which is often implemented by visiting veterinarians, despite widely-held opinions that fly-in-fly-out services provide only temporary solutions. We conducted participatory research in a group of remote communities in northern Australia to explore how dog-related problems arise and are managed, and explain their impacts from a One Health perspective. Over the course of a year, 53 residents from a range of backgrounds contributed through in-depth interviews with key community service providers, and informal semi-structured discussions with community residents. Free-roaming dogs have broader impacts on canine and human health than previously documented. Dog-keeping norms that enable free-roaming can enhance human and dog wellbeing and intra-family connectivity. This can also cause disengagement and conflict with other residents, leading to resentment and occasionally violence towards dogs. Dog-related problems are underpinned by constraints associated with remote-living, governance and differing sociocultural norms. Focusing on dog population reduction detracts from the welfare benefits and sociocultural value of free-roaming dogs and undermines community-determined management that can overcome constraints to support local values and co-promote canine and human wellbeing.

Evaluation of a Dog Population Management Intervention: Measuring Indicators of Impact

Dogs are important companions to people but can also present challenges to health and safety of communities if their populations are not effectively managed. Dog population management (DPM) is often undertaken by individual dog owners; however, some communities require additional DPM interventions, especially when veterinary services are unavailable or underutilised. This study evaluated the effectiveness of a DPM intervention conducted in 13 communities between September 2016 and November 2019 and assessed the utility of routinely collected data-program metrics and secondary data collected by local governments-to measure indicators of impacts. The intervention resulted in significant increases in the proportion of dogs presenting that were microchipped and surgically sterilised in participating communities. The intervention also resulted in significant reductions in dog attack incidents and euthanasia of dogs in council pounds in communities that participated for three or more years. Ongoing monitoring and evaluation of DPM interventions is critical to determine if impacts are being achieved. This study demonstrates the potential benefits of a DPM intervention for community safety and dog welfare and highlights the utility of routinely collected data. We also suggest benchmarks for indicators of community engagement to guide planning and monitoring of similar interventions.

Indigenous community perspectives on dogs in Northern Canada after 10 years of veterinary services indicates improved animal and human welfare

Access to veterinary services in marginalized communities has important implications for people and animals around the world. Subsidized veterinary services are occasionally provided, however, they are seldom evaluated for their value to stakeholders and overall animal health. In 2017, we evaluated a decade-long veterinary program in four remote communities in the Sahtu Settlement Area of the Northwest Territories, Canada to understand if there were changes in dog husbandry and community perceptions of, and experiences with, dogs since an initial assessment at the beginning of the program in 2008. Using questionnaires and a dog census, we found a significant increase over time in dog health indicators, including the proportion of dogs that had received preventive veterinary care and had been sterilized. We documented significant changes in the described purpose of dogs, husbandry practices, experiences with dogs, and attitudes towards dogs and veterinary services. In 2017, respondents commonly described their dog(s) as companions and as part of their family. However, communities differed in the way dogs were housed and fed and in their attitudes towards dogs and dog-related issues. These inter-community differences are noteworthy as they impact service provision, uptake, and evaluation and must be taken into consideration in order to develop effective programs. Regular program evaluations are critical to check in with stakeholders, to ensure the program is meeting community needs, and to optimize effective use of resources.

"They Reckon They're Man's Best Friend and I Believe That." Understanding Relationships with Dogs in Australian Aboriginal Communities to Inform Effective Dog Population Management

Simple Summary

Dogs are an important part of many communities; however, they can also cause problems, especially when they are able to roam freely. The best way to manage dog populations to avoid health and safety risks to people varies between different societies and communities. We aimed to better understand the role of dogs in Aboriginal communities in Australia, to inform dog health interventions. Interviews with dog owners in nine Aboriginal communities in New South Wales, Australia showed that dogs are valued as companions and guardians and are considered part of the family. Many dogs spend a lot of time with their families, are allowed indoors and often share beds with people. However, many dog owners had trouble accessing veterinary services for their dogs; cost and lack of transport were the most important barriers. Our findings demonstrate the positive role of dogs in Aboriginal families and communities but also highlight major challenges in accessing the veterinary services necessary to effectively maintain dog health and welfare. We also show that different ideas about the role of dogs in different communities should inform how dog management interventions are designed and delivered.

Abstract

Dogs are important companions to people in many societies; however, dogs can also be associated with risks to public health and safety. Dog population management is therefore an important consideration globally. This study aimed to better understand the role of dogs in Aboriginal communities and the barriers to accessing veterinary services. Semi-structured interviews were conducted with 85 dog owners from nine Aboriginal communities across New South Wales, Australia. Many positive aspects of dog ownership were identified and few negatives. Dogs are considered an important part of family and community life and many dogs are allowed indoors (63.4%), even sharing beds with their owners. Most dogs were kept for companionship (84.7%) and/or as guard dogs (45.9%) and all respondents considered their dog part of their family. However, respondents had low levels of engagement with mainstream veterinary services, and many respondents identified significant barriers to accessing veterinary services, especially cost and transport. This study demonstrates the important and positive role of dogs in Aboriginal families and communities but also highlights a significant veterinary service gap. Our findings demonstrate that different perspectives on the role of dogs necessitates a different, culturally inclusive approach to dog management interventions.

Epidemiology of human exposure to rabies in Nunavik: incidence, the role of dog bites and their context, and victim profiles

Background

In Nunavik, Arctic rabies is still endemic due to a spillover from wildlife to dogs. The prevention of human exposure and the management of potential exposure is a significant public health concern in this region.

Methods

This study retrospectively describes cases of potential exposure to rabies in humans as reported to the Nunavik Public Health Board through their registry of reported cases. We used multi-correspondence analysis as well as univariable and multivariable regression models to test for differences between children and adults in reported cases, and to examine the contexts of exposure to dogs and dog attacks.

Results

From 2008 to 2017, 320 cases of potential exposure to rabies were reported, 92% of which were linked to dogs. The annual incidence rate was 2.5 per 1000 people. The incidence increased significantly during the study period, although the reasons for this are unclear. Fifteen cases of exposure were with rabid animals, mostly dogs (9 of 15). No human cases of rabies occurred thanks to adequate medical case management. Two specific profiles for potential exposure to rabies were identified based on age and gender. The first was children (< 15 y/o), male or female, who were more likely to be exposed through playing with dogs and were more often injured in the head and/or neck. The second was young male adults (aged 15 to 34 y/o), who were more involved with wildlife than other age groups and mostly injured in the upper limbs and as a result of a reaction by the animal.

Conclusion

Rabies is a real public health threat in Nunavik. Potential human exposure needs to be prevented, and prevention measures should be tailored to the two risk profiles identified based on age, gender and animal species involved.

Desexing Dogs: A Review of the Current Literature

Background: Desexing dogs is promoted for population control, preventative healthcare, and behavior modification. Common methods are orchiectomy and ovariectomy/ovariohysterectomy. GnRH superagonist implants are available in some areas. Alternative methods like vasectomy and salpingectomy/hysterectomy are uncommon. The terminology used to describe desexing is inconsistent and contradictory, showing a need for the adaption of standardized terminology. Population Control: Surprisingly, empirical studies show no effects of desexing on population control in companion and shelter dogs despite desexing being consistently recommended in the literature. There is evidence for a population control effect in free-roaming dogs, where desexing also has benefits on zoonotic disease and bite risk. Population control in free-roaming dogs is mostly correlated with female, not male desexing. Health and Lifespan: Desexing affects numerous disease risks, but studies commonly neglect age at diagnosis and overall lifespan, age being by far the most important risk factor for most diseases. We argue that lifespan is a more important outcome than ultimate cause of death. A beneficial effect of desexing on lifespan is consistently demonstrated in females, while evidence for a beneficial effect in males is inconsistent. Studies are likely biased in desexing being a proxy for better care and desexed dogs having already lived to the age of desexing. Desexing reduces or eliminates common life-limiting diseases of the female reproductive system such as pyometra and mammary tumors, while no analogous effect exists in males. Disease risks increases across sexes and breeds include cruciate ligament rupture, various cancers, and obesity. Urinary incontinence risk is increased in females only. Various other disease risk changes show considerable variability between breeds and sexes. Behavioral Effects: Desexed males show reduced libido, roaming, conspecific mounting, and urinary marking frequency, as well as reduced male dog-directed aggression in a majority of males desexed for behavioral reasons. There is a detrimental effect on the risk and progression of age-related cognitive dysfunction. Desexed dogs may be less likely to cause bite injuries across sexes. The evidence for other effects such as human-directed aggression, human or object mounting, resource guarding, or shyness and anxiety is inconsistent and contradictory. There are few studies specific to females or individual breeds. Conclusions: The evidence for a beneficial effect of desexing is stronger in female than in male dogs; however, there is significant variation between breeds and sexes, and more research is needed to further elucidate these differences and to arrive at individualized evidence-based recommendations for clinical practice.

The Effectiveness of Dog Population Management: A Systematic Review

Simple Summary

Domestic dogs are abundant worldwide—as owned pets, unowned strays, and feral animals. High numbers of free-roaming dogs can be a concern because of the risks they pose to public health, animal welfare, and wildlife. Using a systematic review process, we investigated what the research published to date can tell us about the effectiveness of different dog population management methods. We found that management methods for dog populations have been researched in multiple countries worldwide, using a wide range of indicators to assess method effectiveness. We outline the results and suggest improvements to help guide future dog population management policy.

Abstract

The worldwide population of domestic dogs is estimated at approximately 700 million, with around 75% classified as “free-roaming”. Where free-roaming dogs exist in high densities, there are significant implications for public health, animal welfare, and wildlife. Approaches to manage dog populations include culling, fertility control, and sheltering. Understanding the effectiveness of each of these interventions is important in guiding future dog population management. We present the results of a systematic review of published studies investigating dog population management, to assess: (1) where and when studies were carried out; (2) what population management methods were used; and (3) what was the effect of the method. We evaluated the reporting quality of the published studies for strength of evidence assessment. The systematic review resulted in a corpus of 39 papers from 15 countries, reporting a wide disparity of approaches and measures of effect. We synthesised the management methods and reported effects. Fertility control was most investigated and had the greatest reported effect on dog population size. Reporting quality was low for power calculations (11%), sample size calculations (11%), and the use of control populations (17%). We provide recommendations for future studies to use common metrics and improve reporting quality, study design, and modelling approaches in order to allow better assessment of the true impact of dog population management.

Giardia Infection and Trypanosoma Cruzi Exposure in Dogs in the Bosawás Biosphere Reserve, Nicaragua

Indigenous Mayangna and Miskitu inhabit Nicaragua's remote Bosawás Biosphere Reserve, located in the North Caribbean Coast Autonomous Region. They are sedentary horticulturists who supplement their diet with wild game, hunting with the assistance of dogs. To test whether hunting dogs increased the risk of human exposure to protozoal zoonotic neglected tropical diseases (NTDs), we sampled dogs from three communities varying in population size and level of contact with other communities. We screened dog feces (n = 58) for Giardia and Cryptosporidium DNA and sera (n = 78) for Trypanosoma cruzi antibodies and DNA. Giardia DNA was detected in 22% (13/58) of samples; sequencing revealed the presence of both zoonotic genotypes (assemblages A and B) and dog-specific genotypes (assemblages C and D). Giardia shedding was associated with community and age. Older dogs and those in the two, more accessible communities had greater odds of shedding parasites. Seroprevalence of T. cruzi antibodies, indicating prior exposure, was 9% (7/78). These results contribute to the limited literature on NTDs in indigenous populations, and suggest hunting dogs can both serve as sentinels of environmental NTDs and pose zoonotic risk for their owners and communities.

Insights about the Epidemiology of Dog Bites in a Canadian City Using a Dog Aggression Scale and Administrative Data

Simple Summary

Any dog is capable of biting, and dog bites can cause serious injuries to humans or other animals. To prevent dogs from biting, we need to understand the circumstances in which dog bites are most likely to occur. Once we have that information, we can act by improving public awareness and tailoring interventions to those most at risk of being injured. In this study, we assess the circumstances surrounding dog-bite injuries, by considering dog-bite severity in conjunction with information about where the incident occurred, about human victims, and about the dogs themselves. This approach was possible because The City of Calgary systematically tracks dog-bite severity. We found that from 2012–2017, the number of severe bites occurring in Calgary has fallen. That said, severe bites tended to occur in the homes where the dogs lived, and to be directed towards children and older adults. The results from our study underscore that educational communication for parents, grandparents, and other caregivers should emphasize the importance of constant supervision around dogs, including family dogs, whenever children are present. In addition, more attention should be paid to the risks that dogs pose to older adults. Failure to protect people from dog-bite injuries has implications for the dogs’ own welfare, as well as for human health. Dogs are most likely to bite when they feel insecure in the first place. Furthermore, common responses to severe dog-bite injuries in people include rehoming and euthanizing dogs.

Abstract

Dog bites are a public health concern that also implicates animal welfare, with negative outcomes such as rehoming or euthanasia for the animals responsible. Previous research has shown that the severity of dog-bite injuries reflects multiple factors, including the degree of inhibition exhibited by dogs and how people behave towards dogs. This study utilizes an objective dog bite injury assessment tool: The Dunbar aggression scale. Trained officers employed by The City of Calgary systematically use the Dunbar scale whenever investigating dog-bite complaints. We analyzed The City of Calgary’s administrative data on confirmed dog-bite injuries in people, 2012–2017, with a multivariable generalized ordered logistic regression model. Severe dog-bite injuries occurred more frequently in the family home than in any other setting. Young children, youths and older adults were at higher risk of more serious bites than adults. There has been a decreasing trend in the probability of a high or medium severity bite, and an increasing trend in the probability of a low severity bite since 2012. These results indicate that greater public awareness regarding dog-bite injuries is needed. Consideration should be given to campaigns targeted towards different demographics, including older adults, to provide an understanding of dog behaviour and to emphasize the need to supervise children closely in the presence of all dogs at all times, including family dogs in the home environment. Given that dog-bite injuries are not just a public health issue, but also an animal welfare issue, we endorse One Health responses in educational campaigns, policy development, and professional practice.

Scoping decades of dog evidence: a scoping review of dog bite-related sequelae

OBJECTIVES

There has been considerable literature published focusing on various sequelae to dog bites over the last three decades. Much of the literature has focused on rabies, particularly canine rabies variant, which accounts for the majority of rabies deaths worldwide. This paper describes the complications, the pathogens, and other sequelae resulting from dog bites documented in the literature.

METHODS

This paper used evidence found through a scoping review which charted the published peer-reviewed and non-peer-reviewed gray literature and online information relating to dog bite incidents. Each complication or sequela was additionally assessed from the viewpoint of Canadian Indigenous, rural, and geographically remote communities, which experience a high number of dog bite incidents annually.

SYNTHESIS

Peer-reviewed literature (N = 693; case report, original research, and review articles) provided detailed information on specific pathogens, infections, and diseases of interest, especially rabies. However, in addition to these, the sequelae from dog bites may include moderate to severe injuries that further result in anxiety around dogs or post-traumatic stress disorder (PTSD).

CONCLUSIONS

While a lot of focus in the literature is on rabies as a sequela to dog bites, the impacts of anxiety and PTSD are not as well articulated. Treatment of dog bite injuries may be standardized; however, improved collaborations between diverse health professionals (physicians, veterinarians, counseling services, animal behaviourists, and others) could be of considerable benefit in decreasing the effects of dog bites.

Overcoming challenges for designing and implementing the One Health approach: A systematic review of the literature

Collaborative approaches in health, such as One Health (OH), are promising; nevertheless, several authors point at persistent challenges for designing and implementing OH initiatives. Among other challenges, OH practitioners struggle in their efforts to collaborate across disciplines and domains. This paper aims to provide insights into the existing challenges for designing and implementing OH initiatives, their causes and solutions, and points out strategic solutions with the potential to solve practical challenges. A systematic literature search was performed for emerging challenges and proposed solutions in the process of conducting OH initiatives. Next, a thematic and a causal analysis were performed to unravel challenges and their causes. Finally, solutions were discriminated on whether they were only recommended, or implemented as a proof-of-principle. The 56 included papers describe 21 challenges endured by OH initiatives that relate to different themes (policy and funding; education and training; surveillance; multi-actor, multi-domain, and multi-level collaborations; and evidence). These challenges occur in three different phases: the acquisition of sufficient conditions to start an initiative, its execution, and its monitoring and evaluation. The findings indicate that individual challenges share overlapping causes and crosscutting causal relations. Accordingly, solutions for the successful performance of OH initiatives should be implemented to tackle simultaneously different types of challenges occurring in different phases. Still, promoting collaboration between the wide diversity of stakeholders, as a fundamental aspect in the OH approach, is still by far the most challenging factor in performing OH initiatives. Causes for that are the difficulties in promoting meaningful and equal participation from diverse actors. Solutions proposed for this challenge focused on guiding stakeholders to think and collaborate beyond their professional and cultural silos to generate knowledge co-creation and innovative methodologies and frameworks. Finally, the biggest knowledge gap identified, in terms of proposed solutions, was for monitoring and evaluating OH initiatives. This highlights the need for future research on evaluation methods and tools specific for the OH approach, to provide credible evidence on its added value. When considering challenges endured by former OH initiatives and the proposed solutions for these challenges, practitioners should be able to plan and structure such initiatives in a more successful way, through the strategic pre-consideration of solutions or simply by avoiding known barriers.

Understanding the Connections Between Dogs, Health and Inuit Through a Mixed-Methods Study

Dogs have been an integral part of the Inuit social and cultural environment for generations, but their presence also generates public health risks such as bites and exposure to zoonotic diseases such as rabies. In Nunavik, Canada, some prevention and control interventions targeting dogs have been implemented but have not demonstrated their effectiveness in a long-term sustainable perspective. This study was conducted in one Inuit community of Nunavik and used mixed methods to get a better understanding of factors that affect human and dog health, dog-related risks for humans and perceptions of dogs in Inuit communities using an interdisciplinary perspective in line with the Ecohealth approach. Results unveiled different perceptions and practices between Inuit and non-Inuit members of the community with regard to dogs and highlighted the positive role of dogs and their importance for Inuit health and well-being. This study provides new knowledge that is crucial for the development of integrated, sustainable and culturally adapted solutions to both the mitigation of dog-related health risks and the reinforcement of health and wellness benefits of dogs for Inuit.

Demographic studies of owned dogs in the Northern Peninsula Area, Australia, to inform population and disease management strategies

OBJECTIVE

To generate domestic dog demographic information to aid population and disease management in the Aboriginal and Torres Strait Islander communities of the Northern Peninsula Area, Queensland, Australia.

METHODS

Sight-resight surveys using standard and modified methods were conducted to estimate the free-roaming dog population size. A cross-sectional questionnaire of dog owners was used to gather dog demographic information and investigate owners' dog management behaviours. A survey was also conducted to estimate the total dog population size.

RESULTS

The mean total dog population size was estimated to be 813 (range, 770-868). The roaming dog population was 430 or 542 (95% confidence interval (CI) 254-608; 95% CI 405-680, standard and modified methods, respectively). Therefore, the roaming population represents 52.8% or 66.7% of the total population based on the sight-resight methodology. We surveyed 65 dog owners who owned 165 dogs (1 : 1 ratio of male : female dogs). Only 14% (95% CI 9-19) of dogs were sterilised and significantly more males were entire (P = 0.02). Although most dogs were pets (65%), hunting dogs were significantly more likely to be taken outside of the resident community (P < 0.001). The birth rate was 2.4 puppies/dog-owning house/year, which was higher than the death rate (1.7 dogs/dog-owning house/year). In the previous 12 months, 90% of the 109 deaths were dogs aged 0-2 years old.

CONCLUSION

This study demonstrated that most of the dog population in the NPA is free-roaming and that the population has increased, likely because of a lack of population management strategies such as sterilisation. This information will be used to develop population and disease management strategies in the NPA.

Exploring the Social Determinants of Animal Health

An understanding of the One Health and EcoHealth concepts by students is dependent on medical pedagogy and veterinary medical pedagogy having similarities that allow a common discourse. Medical pedagogy includes a focus on the social, political, and economic forces that affect human health, while this discourse is largely absent from veterinary medical pedagogy. There is, however, a gradient in health that human and animal populations experience. This health gradient in human populations, which runs from low to high according to the World Health Organization, is largely explained by "the conditions in which people are born, grow, live, work, and age."^1,2 Regarding the human health gradient, other authors have broadened the list of conditions to include access to health care systems used to prevent disease and treat illness, and the distribution of power, money, and resources, which are shaped by social, economic, and political forces.^1,2 In human medicine, these conditions are collectively termed the social determinants of health (SDH). Veterinarians who work with the public encounter people and their animals at both the low and the high end of the health gradient. This article explores the concept of the parallel social determinants of animal health (SDAH) using examples within urban, rural, and remote communities in North America as well as abroad. We believe that in order to understand the One Health paradigm it is imperative that veterinary pedagogy include information on, and competence in, SDH and SDAH to ultimately achieve improvements in human, animal, and environmental health and wellbeing.

Rocky Mountain spotted fever in Mexico: past, present, and future

Rocky Mountain spotted fever, a tick-borne zoonosis caused by Rickettsia rickettsii, is among the most lethal of all infectious diseases in the Americas. In Mexico, the disease was first described during the early 1940s by scientists who carefully documented specific environmental determinants responsible for devastating outbreaks in several communities in the states of Sinaloa, Sonora, Durango, and Coahuila. These investigators also described the pivotal roles of domesticated dogs and Rhipicephalus sanguineus sensu lato (brown dog ticks) as drivers of epidemic levels of Rocky Mountain spotted fever. After several decades of quiescence, the disease re-emerged in Sonora and Baja California during the early 21st century, driven by the same environmental circumstances that perpetuated outbreaks in Mexico during the 1940s. This Review explores the history of Rocky Mountain spotted fever in Mexico, current epidemiology, and the multiple clinical, economic, and social challenges that must be considered in the control and prevention of this life-threatening illness.

Evaluating one health: Are we demonstrating effectiveness?

The perceived benefits of a One Health approach are largely hinged on increasing public health efficiency and cost effectiveness through a better understanding of disease risk-through shared control and detection efforts, and results that benefit human, animal and ecosystem health. However, there have been few efforts to identify and systematize One Health metrics to assess these perceived efficiencies. Though emphasis on the evaluation of One Health has increased, widely cited benefits of One Health approaches have mainly been based on modeled projections, rather than outcomes of implemented interventions. We conducted a review of One Health literature to determine the current status of One Health frameworks and case studies reporting One Health metrics. Of 1839 unique papers, only 7 reported quantitative outcomes; these assessments did not follow shared methodology and several reviewed only intermediate outcomes. For others, the effectiveness of One Health approaches was often assumed without supporting evidence or determined subjectively. The absence of a standardized framework to capture metrics across disciplines, even in a generic format, may hinder the more widespread adoption of One Health among stakeholders. We review possible outcome metrics suitable for the future evaluation of One Health, noting the relevance of cost outcomes to the three main disciplines associated with One Health.

Free-Roaming Dogs in Nepal: Demographics, Health and Public Knowledge, Attitudes and Practices

In Nepal, most dogs are free to roam and may transmit diseases to humans and animals. These dogs often suffer from malnutrition and lack basic health care. Minimal information is available about their demographics and about public attitudes concerning dogs and diseases. We carried out a study in Chitwan District (central Nepal), to collect baseline data on free-roaming owned dog demographics, assess knowledge, attitudes and practices of dog owners concerning dogs and rabies, evaluate rabies vaccination coverage and anthelmintic treatment of dogs, measure dogs' response to rabies vaccination and assess dog health through body condition scores and parasites. We conducted household interviews with owners of free-roaming female dogs (n = 60) and administered dogs with rabies vaccination and anthelmintics. Dog owners regularly fed free-roaming dogs but provided minimal health care; 42% of respondents did not claim ownership of the dog for which they provided care. We collected skin, faecal and blood samples for parasite identification and for measuring rabies virus-specific antibodies. Ninety-two per cent of dog owners were aware of the routes of rabies virus transmission, but only 35% described the correct post-exposure prophylaxis (PEP) following a dog bite. Twenty-seven per cent of the dogs had measurable rabies virus-specific antibody titres and 14% had received anthelmintics in the previous year. Following rabies vaccination, 97% of dogs maintained an adequate antibody titre for ≥6 months. Most dogs appeared healthy, although haemoprotozoans, endoparasites and ectoparasites were identified in 12%, 73% and 40% of the dogs, respectively. Poor skin condition and parasite load were associated. Seventy-four per cent of the females had litters in 1 year (mean litter size = 4.5). Births occurred between September and February; we estimated 60% mortality in puppies. We concluded that vaccination coverage, PEP awareness and anthelmintic treatment should be emphasized in educational programmes focussed on animal welfare, veterinary and public health.

Who Let the Dogs Out? Communicating First Nations Perspectives on a Canine Veterinary Intervention Through Digital Storytelling

Dog-related human injuries affect public safety and animal welfare, and occur more frequently in rural, remote, and Indigenous communities than in urban centres in Canada. Little work has been done to identify the perspectives of those people most heavily affected by this issue or to report successful dog management programs. This project was undertaken by veterinarians and public health workers with the goal of documenting First Nations perspectives on dogs, and educating other rural health workers about introducing animal management services to Indigenous communities. We recruited 10-14 residents and healthcare workers from three First Nations to take dog-related photos in their communities and participate in group interviews during the summer of 2014. Audiovisual data were synthesised into four digital stories exploring the following aspects of participant relationships with community dogs: (1) Spay/neuter clinics; (2) Role of the dog (past and present); (3) Human-animal bond; and (4) Healthy dogs as a part of healthy communities. These videos document changes in dog husbandry behaviour, new acceptance of spay/neuter, three-way knowledge transfer between residents, researchers, and policy makers, and an overall desire to sustain the positive outcomes of the pilot dog management project. This work highlights cultural beliefs and success strategies that might guide other programs providing veterinary services in First Nations communities.

Echinococcosis: An Economic Evaluation of a Veterinary Public Health Intervention in Rural Canada

Echinococcosis is a rare but endemic condition in people in Canada, caused by a zoonotic cestode for which the source of human infection is ingestion of parasite eggs shed by canids. The objectives of this study were to identify risk factors associated with infection and to measure the cost-utility of introducing an echinococcosis prevention program in a rural area. We analyzed human case reports submitted to the Canadian Institutes for Health Information between 2002 and 2011. Over this 10 year period, there were 48 cases associated with E. granulosus/E. canadensis, 16 with E. multilocularis, and 251 cases of echinococcosis for which species was not identified (total 315 cases). Nationally, annual incidence of echinococcosis was 0.14 cases per 100 000 people, which is likely an underestimate due to under-diagnosis and under-reporting. Risk factors for echinococcosis included female gender, age (>65 years), and residing in one of the northern territories (Nunavut, Yukon, or Northwest Territories). The average cost of treating a case of cystic echinococcosis in Canada was $8,842 CAD. Cost-utility analysis revealed that dosing dogs with praziquantel (a cestocide) at six week intervals to control cystic echinococcosis is not currently cost-effective at a threshold of $20,000-100,000 per Quality Adjusted Life Year (QALY) gained, even in a health region with the highest incidence rate in Canada ($666,978 -755,051 per QALY gained). However, threshold analysis demonstrated that the program may become cost-saving at an echinococcosis incidence of 13-85 cases per 100,000 people and therefore, even one additional CE case in a community of 9000 people could result in the monetary benefits of the program outweighing costs.

In Canada, Echinococcus spp. tapeworms cycle primarily among wildlife hosts. People are infected with this parasite when they accidentally consume microscopic eggs spread by canids (e.g. dogs, wolves, coyotes, and foxes), and develop larval cysts, often in the liver or lungs. Echinococcosis can be a life-threatening medical condition with long-term health consequences and can be an economic burden for infected individuals and for the public health system. We analysed national health records to measure echinococcosis incidence and risk factors in Canada, and then used this information to determine if a program that facilitated dog deworming to prevent human infection might be economically feasible. Our model suggested that treating infected individuals is currently less expensive than preventing infection, even in the highest risk regions of Canada. However, deworming dogs might be feasible in small rural communities where at least one case was identified. Furthermore, the prevention program has many add-on benefits that contribute to overall community health, but are not measured by our model.
