Assessing the effect of a canine surgical-neutering educational programme on the knowledge and confidence of Indian veterinary participants

India has a large, free-roaming dog population, encompassing both owned and stray dogs. Canine surgical neutering is often a central component of dog population management and rabies control initiatives. The provision of practical, surgical training opportunities remains a major challenge for veterinary educational establishments worldwide to ensure competency in this routine procedure. A 12-day educational programme, focusing on surgical neutering skills, was developed to address this need. A questionnaire comprising 26 questions covering surgical and clinical topics, and a self-assessment of confidence in undertaking five common surgical procedures, was completed immediately before and after finishing the programme. A total of 296 participants attended, with 228 achieving the inclusion criteria for the study. Total knowledge scores increased significantly after the training programme (mean score pre-18.94, 95% CI 18.13-19.74; post-28.11, 95% CI 27.44-28.77, p < 0.05) with improvements seen in all categories (surgical principles, anaesthesia, antibiotic use and wound management). After accounting for other participants' characteristics, scores increased, on average, by 9 points after training. Being female was associated with significantly higher overall scores, while compared to younger and older age groups, those aged 25-34 were associated with lower overall scores. Amongst those with post-graduate qualifications, overall scores increased with age. Furthermore, there was an increase in self-rated confidence by participants in undertaking all five procedures. This study demonstrates that a targeted training programme can improve veterinary participants' knowledge and confidence in canine surgical neutering and may provide an effective way to develop surgical expertise amongst veterinarians engaged in dog population management initiatives.

Impact Assessment of Free-Roaming Dog Population Management by CNVR in Greater Bangkok

A high-intensity catch, neuter, vaccinate and return (CNVR) intervention was used over 5 years to manage the free-roaming dog population of Greater Bangkok, using nearly 300,000 CNVR operations across six provinces. An evaluation was conducted using multiple methods to assess the impact of this intervention, including clinical data, an observational street survey, an online attitude survey and reported cases of dog rabies confirmed with laboratory testing. The evaluation found evidence of a reduction in free-roaming dog density over time (24.7% reduction over 5 years), a reduction in dog rabies cases (average reduction of 5.7% rabies cases per month) and an improvement in dog-human relationships (a 39% increase per year in free-roaming dogs with visible signs of ownership or care and a perception of less trouble with free-roaming dogs in districts benefiting from CNVR). The CNVR intervention appears to have been effective at reducing the current free-roaming dog population and minimizing one future source of free-roaming dogs by limiting breeding of dogs accessible on the streets. However, there is evidence that other sources of free-roaming dogs exist, presumed to be predominately abandoned or lost owned dogs that were previously inaccessible to the CNVR intervention because they were ordinarily confined or living outside the project area. Hence, fully effective dog population management will require further interventions targeting owned dogs in addition to this CNVR effort.

Abandonment of dogs in Latin America: Strategies and ideas

In this article, we gathered information from postgraduate theses and scientific articles published in several databases using inclusion criteria that had been made in Latin America, in countries with similar economic conditions, and also in the USA to present a point of comparison. The objective of this review is to broaden the readers’ understanding of the causes of the increasing numbers of stray dogs and the reasons why people abandon pets in the streets, specifically in Latin America. It also discusses adoption and responsible ownership, identifies what failed in promoting positive human-dog interaction, and suggests strategies to address this problem. It concludes that adoption alone is not an effective solution but that it is necessary to offer education and awareness programs for owners, organize sterilization campaigns, and develop and apply – with the corresponding authorities – measures to ensure animal welfare that will provide benefits for society and improve animal quality of life. The role of veterinarians is fundamental in education and in disseminating the necessary information to orient people before they acquire a pet and prevent animal abandonment to resolve this problem.

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.

"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.

Size, spatial and household distribution, and rabies vaccination coverage of the Brazilian owned-dog population

Dog rabies and human rabies transmitted by dogs can be prevented through adequate dog vaccination coverage. For surveillance purposes, this coverage must be calculated using accurate population size estimates to avoid misleading conclusions. We used data from a Brazilian national survey comprising 64,348 households, to calculate point estimates and confidence intervals of the size, household density, and rabies vaccination coverage of the owned-dog population in Brazilian federative units. We also evaluated the precision of owned-dog population size estimates, based on the extrapolation among different areas, of the mean number of dogs per household and the human/dog ratio. The estimated owned-dog population size in Brazil was 52,198,324 (95% CI = 51,028,583-53,368,066) and the dog vaccination coverage was 80.09% (95% CI = 79.09%-81.09%). Both estimates had marked variation across Brazilian federative units and urban/rural strata. Only two of the 27 federative units had a confidence interval in rural vaccination coverage above 70% and six did not pass this threshold in their urban stratum. For the first time, we reported probabilistic estimates for an entire country and its main administrative areas. The estimated coverage for the country was high because the most populated federative unit also had high coverage. The mean number of dogs per household and the human/dog ratio were useful as survey estimates to characterize owned-dog density. However, the simple extrapolation of these parameters resulted in estimates of owned-dog population sizes with large errors (up to 254%) that must be interpreted with caution to avoid misleading conclusions. To evaluate the dog population size, we recommend the use of probabilistic sampling designs instead of simple human/dog ratio extrapolations, and the inclusion of animal-related questions in censuses and national surveys to obtain reliable estimates to support improvements in animal and human health.

A Comparative Study of Enumeration Techniques for Free-Roaming Dogs in Rural Baramati, District Pune, India

The presence of unvaccinated free-roaming dogs (FRD) amidst human settlements is a major contributor to the high incidence of rabies in countries such as India, where the disease is endemic. Estimating FRD population size is crucial to the planning and evaluation of interventions, such as mass immunisation against rabies. Enumeration techniques for FRD are resource intensive and can vary from simple direct counts to statistically complex capture-recapture techniques primarily developed for ecological studies. In this study we compared eight capture-recapture enumeration methods (Lincoln-Petersen's index, Chapman's correction estimate, Beck's method, Schumacher-Eschmeyer method, Regression method, Mark-resight logit normal method, Huggin's closed capture models and Application SuperDuplicates on-line tool) using direct count data collected from Shirsuphal village of Baramati town in Western India, to recommend a method which yields a reasonably accurate count to use for effective vaccination coverage against rabies with minimal resource inputs. A total of 263 unique dogs were sighted at least once over 6 observation occasions with no new dogs sighted on the 7th occasion. Besides this direct count, the methods that do not account for individual heterogeneity yielded population estimates in the range of 248-270, which likely underestimate the real FRD population size. Higher estimates were obtained using the Huggin's Mh-Jackknife (437 ± 33), Huggin's Mth-Chao (391 ± 26), Huggin's Mh-Chao (385 ± 30), models and Application "SuperDuplicates" tool (392 ± 20) and were considered more robust. When the sampling effort was reduced to only two surveys, the Application SuperDuplicates online tool gave the closest estimate of 349 ± 36, which is 74% of the estimated highest population of free-roaming dogs in Shirsuphal village. This method may thus be considered the most reliable method for estimating the FRD population with minimal inputs (two surveys conducted on consecutive days).

Direct Observation of Dog Density and Composition during Street Counts as a Resource Efficient Method of Measuring Variation in Roaming Dog Populations over Time and between Locations

Dog population management is conducted in many countries to address the public health risks from roaming dogs and threats to their welfare. To assess its effectiveness, we need to monitor indicators from both the human and dog populations that are quick and easy to collect, precise and meaningful to intervention managers, donors and local citizens. We propose that the most appropriate indicators from the roaming dog population are population density and composition, based on counting dogs along standard routes using a standard survey protocol. Smart phone apps are used to navigate and record dogs along standard routes. Density expressed as dogs seen per km predicts the number of dogs residents will encounter as they commute to work or school and is therefore more meaningful than total population size. Composition in terms of gender, age and reproductive activity is measured alongside welfare, in terms of body and skin condition. The implementation of this method in seven locations reveals significant difference in roaming dog density between locations and reduction in density within one location subject to intervention. This method provides a resource efficient and reliable measure of roaming dog density, composition and welfare for the assessment of intervention impact.

The Role of Dog Population Management in Rabies Elimination-A Review of Current Approaches and Future Opportunities

Free-roaming dogs and rabies transmission are integrally linked across many low-income countries, and large unmanaged dog populations can be daunting to rabies control program planners. Dog population management (DPM) is a multifaceted concept that aims to improve the health and well-being of free-roaming dogs, reduce problems they may cause, and may also aim to reduce dog population size. In theory, DPM can facilitate more effective rabies control. Community engagement focused on promoting responsible dog ownership and better veterinary care could improve the health of individual animals and dog vaccination coverage, thus reducing rabies transmission. Humane DPM tools, such as sterilization, could theoretically reduce dog population turnover and size, allowing rabies vaccination coverage to be maintained more easily. However, it is important to understand local dog populations and community attitudes toward them in order to determine whether and how DPM might contribute to rabies control and which DPM tools would be most successful. In practice, there is very limited evidence of DPM tools achieving reductions in the size or turnover of dog populations in canine rabies-endemic areas. Different DPM tools are frequently used together and combined with rabies vaccinations, but full impact assessments of DPM programs are not usually available, and therefore, evaluation of tools is difficult. Surgical sterilization is the most frequently documented tool and has successfully reduced dog population size and turnover in a few low-income settings. However, DPM programs are mostly conducted in urban settings and are usually not government funded, raising concerns about their applicability in rural settings and sustainability over time. Technical demands, costs, and the time necessary to achieve population-level impacts are major barriers. Given their potential value, we urgently need more evidence of the effectiveness of DPM tools in the context of canine rabies control. Cheaper, less labor-intensive tools for dog sterilization will be extremely valuable in realizing the potential benefits of reduced population turnover and size. No one DPM tool will fit all situations, but if DPM objectives are achieved dog populations may be stabilized or even reduced, facilitating higher dog vaccination coverages that will benefit rabies elimination efforts.

A Century Spent Combating Rabies in Morocco (1911-2015): How Much Longer?

Rabies has no known beginning in Morocco and to date, government control efforts and plans fail to eradicate the disease. A review and analysis of available epidemiological data are crucial to learn lessons from the past and to propose effective actions. Legally, animal rabies is a notifiable disease since 1913 and legislation has been updated periodically since. Dogs have always been considered as both the disease's vector and reservoir, while cattle, other herbivores, and humans are victims. Animal rabies cases evolution from 1942 to 2015 is characterized by ascending phase then decreasing one following structured rabies control plan implementation in 1980s. Indeed, from 1986 to 2010, three rabies control plans have been conducted based on free of charge rabies vaccination of owned dogs through mass campaigns. The geographical distribution of rabies is stable over the years with highest cases number in rich rural areas and around cities. Human rabies cases are decreasing over the time (1976-2015) thanks to the opening of new antirabic treatment centers in the last decade which permit the administration of more PEPs. After a century of rabies control, Morocco registered an average of 301 animal cases and 21 human cases annually for the last decade (2005-2015). Few reasons led to those limited results. The lack in law enforcement and, moreover, the fact that the law do not take into account responsible dog ownership aspect are of importance. Lack of dog population knowledge and management and intersectoral coordination deficiency are additional failure reasons. The gathered data will help to build a new strategy with a focus on a "One Health" approach. Dog population ecology parameters' study is of primary importance. We estimated dog population to be 2.8 million dogs based on human:dog ratio. Enhancing vaccination coverage of dog population is feasible by combining parenteral vaccination and complementary oral vaccination. Updating legislation by inclusion of responsible dog ownership and law enforcement are crucial. Over the last century, Morocco registered a slow decreasing tendency in the number of animal and human rabies cases. Urgent strategy need to be implemented because rabies elimination is an achievable goal in Morocco.

Eliminating Dog-Mediated Rabies in Sikkim, India: A 10-Year Pathway to Success for the SARAH Program

A third of the world rabies burden is in India. The Sikkim Anti-Rabies and Animal Health (SARAH) program is the first state-wide rabies program in India and demonstrates a successful One Health model of dog-mediated rabies elimination. The SARAH program was created in 2006 as a collaboration between the Government of Sikkim and international non-government organizations-Vets Beyond Borders and Fondation Brigitte Bardot. Activities are directed to canine rabies vaccination, humane dog population control, community education, and treatment of sick and injured animals. In 2005, there were 0.74 human rabies deaths per 100,000 (4 deaths) within Sikkim, and from 2006 to 2015, there were no human rabies deaths. In 2016, two human rabies deaths were reported near the West Bengal border region. From 2005 to 2010, the incidence of animal rabies is unknown; from 2010 to 2016, eight cases of animal rabies were reported. Major challenges for the program are continued commitment to rabies control in the face of 0 to low human rabies incidence and the risk of rabies incursions. Effective intersectoral communication between Health, Veterinary, Forestry, and Police officers is essential to enable rapid response to animal bite incidents and possible rabies incursions. An integrated One Health approach needs to be maintained with enhanced active rabies surveillance. Other states must establish similar programs if India is ever to achieve a goal of eliminating dog-mediated human rabies.
