Saving normal: A new look at behavioral incompatibilities and dog relinquishment to shelters

Dog Neuter, Yes or No? A Summary of the Motivations, Benefits, and Harms, with Special Emphasis on the Behavioral Aspect

The decision to neuter pet dogs remains a significant and ongoing debate from ethical, animal health, and animal welfare perspectives. Millions of dogs worldwide are considered integral family members, and their behavior, as well as the bond they form with their owners, play a key role in the decision to keep them as pets. When behavioral problems arise, neutering is often viewed as a potential solution. However, by removing the source of sexual hormones, neutering creates the potential for both beneficial and harmful effects on a dog's health and behavior. It is crucial for society to rely on professionals to provide informed advice about whether and when the procedure should be performed on a pet, taking into account the unique risks and benefits of each individual case. Instead, the conclusions drawn from existing research-both in terms of behavior and health aspects-remain inconclusive and sometimes conflicting. Studies have reported higher risks for developing reproductive, urinary, metabolic, and musculoskeletal disorders in neutered dogs. Additionally, some studies suggest increases in stress, fear, anxiety, and even certain types of aggression following neutering. The limitations of current research, the subjectivity of pet owners' evaluations of their dogs' behaviors, the influence of various demographic factors, and the complex relationships between sex hormones and other hormones or neurotransmitters all contribute to the challenges in this field of study. Despite these complexities, they also offer promising avenues for future research. This review aims to provide a comprehensive overview of the various effects of neutering on dogs, with a particular focus on behavioral outcomes.

A mixed-method analysis of the consistency of intake information reported by shelter staff upon owner surrender of dogs

Data collected by animal shelters can provide an overview of population numbers and recommendations for shelter management and community programming. While studies utilize data from shelter software, questions remain on whether such data are reliable. The objective of the online experiment was to determine the agreement in data input for surrender reason, breed, and color across shelter staff (n = 81) when presented with four complex narratives of fictional owners surrendering dogs. Additionally, we aimed to understand how staff select surrender reasons for data input through qualitative analysis. Out of 40 possible surrender reasons, the number of unique reasons selected for each scenario ranged from 12-16, suggesting a variety of possible data entries for the same surrender narrative. Agreement was also low for breed and color. Shelter staff described a variety of different methods of determining the surrender reason for input into shelter software, such as asking the owner for their most influential reason or inferring the underlying reason. Further research is required to understand how animal shelter data can be collected consistently in a way that can meaningfully inform shelter management decisions.

Behavioural differences and similarities between dog breeds: proposing an ecologically valid approach for canine behavioural research

The behaviour of dogs holds great relevance for not only scientists from fundamental and applied research areas, but also due to the widespread roles of dogs in our societies as companions and working animals; their behaviour is also an important factor in animal and human welfare. A large proportion of dogs currently under human supervision belong to one of roughly 400 recognised breeds. Dog breeds can be characterised by distinctive, predictable and reproducible features, including some of their behavioural traits. To the scientist, the comparative analysis of the behaviour of dog breeds provides an opportunity for investigating an array of intriguing phenomena within an easily accessible model organism created from natural and human-driven evolutionary processes. There are many ways to design and conduct breed-related behavioural investigations, but such endeavours should always be based around biologically relevant research questions and lead to ecologically valid conclusions. In this review, we surveyed recent research efforts that included dog behaviour-related comparisons and applied a critical evaluation according to their methods of breed choice and the subsequent research design. Our aim was to assess whether these two fundamentally important components of experimental design provide a solid basis to reach valid conclusions. Based on 97 publications that fulfilled our selection criteria, we identified three primary methods used by researchers to select breeds for their investigations: (i) convenience sampling; (ii) hypothesis-driven, ancestry-based sampling; and (iii) hypothesis-driven, functional sampling. By using the SWOT (Strengths, Weaknesses, Opportunities, Threats) evaluation system, we highlight each of these techniques' merits and shortcomings. We identify when particular methods may be inherently unable to produce biologically meaningful results due to a mismatch between breed choice and the initial research goals. We hope that our evaluation will help researchers adopt best practices in experimental design regarding future dog breed comparisons.

Human-directed sociability in the domestic dog: A Tinbergian approach

The motivation to interact with humans is central to dogs' domestication process. This review aims to provide a curated overview of the current knowledge about dogs' human-directed sociability using Tinbergen's four questions as a guiding framework. Firstly, we explore its evolutionary history, discussing wolf-dog differences in the socialization period, fear response, sociability, and attachment to elucidate the effect of domestication. Secondly, we address its ontogeny, highlighting the importance of early life experiences, examining findings on different dog populations to discern the effect of adult life experiences, and reporting changes across the lifespan. Thirdly, we analyse the adaptive value of the dog-human relationship, considering the effects of human association on different dog populations. Fourthly, we elaborate on the mechanisms involved in the dog-human relationship, discussing underlying cognitive and genetic processes and findings on the neurophysiological effects of interacting with humans. Finally, we identify issues and remaining questions that deserve more scrutiny and suggest innovative approaches that could be explored to improve our understanding of dogs' human-directed sociability.

The beauty of the beast: Suggestions to curb the excesses of dog breeding and restore animal welfare - Invited review

Dog. Specifically created to save its master's life. - (The dog is the ideal) Friend of man, (because it is his devoted slave) (source: Gustave Flaubert, Dictionnaire des Idées Reçues). But is man the best friend of the dog? This question is legitimate when we consider living situations to which modern domestic dogs are exposed. They often do not satisfy basic animal needs. In this narrative review, the author revisits the history of the dog's presence alongside humans, in the light of current knowledge. The modern dog (breed standards and their interests in canine research) and its breeding strategy, including extreme breeding, will then be given particular attention. Dysfunctional human psychological processes will be explored to make it possible to grasp why the breeding of the modern dog is undergoing such a transformation. Finally, based on these factual and conceptual insights, suggestions to improve canine welfare will be proposed. To be effective, all these must be assessed against real-world conditions.

A survey investigating owner perceptions and management of firework-associated fear in dogs in the Greater Sydney area

OBJECTIVE

To investigate the prevalence of firework-associated fear in dogs in Sydney, owner perception of their dog's response to fireworks, perceived efficacy of interventions to manage fearful behaviours and the frequency of dog owners seeking professional advice for these behaviours.

METHODS

Dog owners in the Greater Sydney area were invited to complete an anonymous online survey.

RESULTS

From 387 valid responses, 44.4% (171 of 385) reported their dogs were fearful of fireworks. The most common fear-related behaviour was seeking an owner or caretaker (120 of 161, 74.5%). Most owners responded by bringing their dog inside or trying to comfort or reassure their dog. Only 22.5% of owners sought professional advice for their dog's fear of fireworks, but of these, 65.5% considered that advice to be effective. Source and breed group were significantly associated with fear of fireworks (P = 0.011, P = 0.036 respectively). Fear of fireworks was also significantly associated with fear of thunder (P < 0.0001), gunshots (P < 0.0001) and vehicles (P = 0.0009).

CONCLUSION

Fear of fireworks and other loud noises negatively impacts canine welfare, yet only a small percentage of owners sought professional advice. There is scope for veterinarians to educate owners and raise awareness about the identification and management of noise-associated fear and reduce the risk of escalation of fearful behaviours.

Why Do People Choose a Particular Dog? A Mixed-Methods Analysis of Factors Owners Consider Important When Acquiring a Dog, on a Convenience Sample of Austrian Pet Dog Owners

Selecting a dog that is incompatible with the owner's expectations can negatively impact both parties. Previous studies on dog acquisition have primarily focused on shelter environments, using closed-ended questions to assess hypothetical preferences. In contrast, our study employed open-ended questions with a convenience sample of Austrian dog owners (N = 1077) to retrospectively explore why the owners chose their dogs. We also examined consistency in owners' responses and the influence of owner characteristics (age, education, household composition, previous dog experience, purpose of acquisition) on their reasons. Content analysis revealed 24 codes; the frequency of codes was 2.4/response. The most frequent codes were breed-based choice (29%), choosing on a whim, without careful consideration (24%), work/sport skills (22%), and rescuing a dog (17%). The least frequent were the age (1%), health (1%), sex (1%), and guarding skills (0.6%) of the dog. Twelve codes were consistent over time, and ten were consistent across dogs, indicating that the owners showed a consistent preference for certain traits. Except for the owner's education level, all characteristics affected the likelihood of mentioning at least one code. Most associations were found with the presence of children in the household: owners with children preferred friendly, easily manageable, and easy-to-train dogs and were less likely to adopt or rescue compared to owners living without children. Our findings also highlight discrepancies between spontaneous (free-text) reports and responses to closed-ended questions, underscoring the importance of qualitative data in better understanding the motivations behind and the factors influencing dog acquisition.

Predictors of successful diversion of cats and dogs away from animal shelter intake: Analysis of data from a self-rehoming website

As animals experience distress in animal shelters, leaders call for increased efforts to divert intake of companion animals away from shelters. One novel intake diversion strategy is supported self-rehoming, where owners find new homes for their animals without surrendering to a physical shelter. This study aimed to identify predictors of successful diversion of animals through the AdoptaPet.com 'Rehome' online platform. Data for dogs (n = 100,342) and cats (n = 48,484) were analysed through logistic regression to assess the association of animal- and owner-related factors and outcome. Overall, 87.1% of dogs and 85.7% of cats were successfully diverted from animal shelters, out of which, 37.8% of dogs and 35.3% of cats were kept by their original owner. Multiple animal-related factors predicted increased odds of diversion (e.g. younger, smaller). Dog and cat owners who set a longer rehoming deadline (i.e. > 8 weeks) were over twice as likely to keep or adopt out their animal. Dog owners who surrendered for owner-related reasons had increased odds of diversion in comparison to animal behaviour issues. We conclude that online-supported, self-rehoming platforms provide pet owners with an alternative to relinquishment that may reduce the intake of animals to shelters; however, owners with animals that are not preferred by adopters may have to decide whether to keep their animal or relinquish their animal to a shelter or rescue. These results provide guidance for animal shelter professionals on the likelihood of successful diversion programmes given certain animal and owner characteristics.
