Evaluation of a behavioral assessment questionnaire for use in the characterization of behavioral problems of dogs relinquished to animal shelters

Puppy Socialisation Experiences in Relation to Age and COVID-19 Lockdown Restrictions in the UK and ROI

Limited socialisation can contribute to the development of undesirable dog behaviours. The COVID-19 lockdown potentially limited socialisation opportunities, which may negatively impact the future behaviour of puppies raised during lockdown. Data were gathered from longitudinal study participants in the United Kingdom/Republic of Ireland via multiple questionnaires between May 2016 and November 2022. The impact of age and lockdown phase (pre-, during, and post-) on the types of socialisation experiences of 8-to-19-week-old puppies and the recency of socialisation experiences of approximately 6-month-old puppies were examined. Puppies under 19-weeks had significantly more types of socialisation experiences (from a predefined list) as they aged, and pre-lockdown compared to post-lockdown, but not between other lockdown phases. Most 6-month-old puppies had met a new adult or dog outside the household, a familiar dog, and/or a child within the last 1-7 days, and this was similar between lockdown phases. During lockdown, 6-month-old puppies experienced longer periods between meeting a new adult in their home. Puppies were hypothesised to have had fewer experiences during lockdown, but this was not found. However, the quantity and quality of these experiences may have been affected. Future research within this longitudinal study will explore relationships between the timing and type of experiences had by puppies and their subsequent behaviour.

Validation of the shortened version of the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) using participants from the Dog Aging Project

The Canine Behavioral Assessment and Research Questionnaire (C-BARQ) is a 100-item owner-completed survey instrument used for assessing behavior and temperament of companion dogs. The shortened version of the C-BARQ (C-BARQ(S)) consists of 42 items of the long C-BARQ. We aimed to validate the shortened C-BARQ(S) by comparing it with the long questionnaire in the same human-dog pair. We examined data from a nationwide cohort of companion dogs enrolled in the large-scale longitudinal Dog Aging Project (DAP) study. Among 435 participating owners who completed both the long and shortened versions of the C-BARQ within 60 days of each other, agreement between individual questions of the long and shortened C-BARQ using an unweighted kappa statistic and percent agreement was examined. Associations between the two questionnaires for mean behavior and temperament domain scores and mean miscellaneous category scores were assessed using Pearson correlation coefficients. Of 435 dogs in the study, the mean (SD) age was 7.3 (4.3) years and 216 (50%) were female. Kappa values between the long and shortened C-BARQ for individual questions within the 14 behavior and temperament domains and a miscellaneous category ranged from fair to moderate (0.23 to 0.40 for 21 items and 0.41 to 0.58 for 26 items, respectively). Pearson correlation coefficients above 0.60 between both questionnaires for 12 of the 14 mean behavior and temperament domain scores and a category of miscellaneous items were observed. Kappa values for individual questions between the long and shortened C-BARQ ranged from fair to moderate and correlations between mean domain scores ranged from moderate to strong.

Companion animal adoption and relinquishment during the COVID-19 pandemic: The experiences of animal rescue staff and volunteers

There has been a paucity of research into the experiences of animal rescue staff and volunteers during COVID-19. The aim of this qualitative research was to explore the impact of the COVID-19 pandemic on companion animal rescue organisations and their staff and volunteers, and to develop a set of recommendations on how to reduce the risk to companion animal welfare during a crisis. Descriptive thematic analysis was used to explore the experiences of staff and volunteers from 28 animal rescue organisations, most of which were based in the UK. Other surveyed countries included Germany, the Republic of Ireland, France, Spain, the USA and Australia. We identify three key themes that reflect the challenges faced by pet rescue organisations during the pandemic: (1) impact on animals; (2) impact on identity; and (3) impact on organisational processes. Key recommendations include the promotion of co-operation and modifications within the sector, the need to understand, and change, detrimental pet-owner behaviours, and the need to clarify the identity of animal rescue organisations within the Government. Both positive and negative outcomes were experienced by animal rescue organisations during the COVID-19 pandemic. These findings should be considered for future crises and indeed the everyday operating procedures of companion animal rescue organisations.

Epilepsy is more than a simple seizure disorder: Parallels between human and canine cognitive and behavioural comorbidities

Psychiatric and cognitive comorbidities have been known to play a major role in human epilepsy for a long time. People with epilepsy (PWE) frequently express signs of varying psychiatric and cognitive disorders affecting their quality and quantity of life (QoL/QaoL). Over the last few years, research on behavioural comorbidities and their effect on the underlying disease have been performed in canine epilepsy. The following article reviews manifestations of comorbidities in canine epilepsy with an emphasis on patterns of clinical signs and their effects on QoL and QaoL. Cognitive and behavioural alterations in epileptic dogs are mainly represented by fear-/anxiety related behaviour and cognitive impairment (CI). Reduced trainability and altered reactions to daily situations are common results of comorbid changes posing obstacles in everyday life of owners and their dog. In addition, clinical signs similar to attention deficit hyperactivity disorder (ADHD) in humans have been reported. Canine attention-deficit-hyperactivity-disorder-like (c-ADHD-like) behaviour should, however, be evaluated critically, as there are no official criteria for diagnosis of ADHD or ADHD-like behaviour in dogs, and some of the reported signs of c-ADHD-like behaviour could be confused with anxiety-associated behaviour. Many intrinsic and extrinsic factors could potentially influence the development of behavioural and cognitive comorbidities in canine epilepsy. In particular, seizure frequency/severity, signalment and factors concerning disease management, such as pharmacotherapy and nutrition, are closely linked with the presence of the aforementioned comorbid disorders. Further studies of behavioural alterations in epileptic dogs are needed to comprehend the complexity of clinical signs and their multifactorial origin.

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.

Trends in Animal Shelter Management, Adoption, and Animal Death in Taiwan from 2012 to 2020

This current study investigated the trends in public animal shelter intakes and outcomes and the workload of shelter veterinarians in Taiwan from 2012 to 2020 and reports spatial, temporal, and socioeconomic factors associated with these trends. Information about the public animal shelter management of dogs and cats from all counties of Taiwan between 2012 and 2020 was acquired from the National Animal Shelter Management System of the Council of Agriculture Executive Yuan in Taiwan. Ridge regression followed by multivariable linear regression was conducted to examine the risk factors for animal intakes, outcomes, the number of adopted animals, and the estimated veterinary workload in public animal shelters. The intakes and outcomes of shelter animals significantly decreased over time. Euthanasia, which was performed in the shelters, was positively associated with shelter animal intakes and outcomes as it resulted in animal outcomes and thus facilitated the flow of animals in the shelters. Adoption and trap-neuter-vaccination-return, in replacement of euthanasia, became the main reasons for animal outcomes, and with every increase in human fertility rate, the monthly number of adopted animals over the number of animals entering shelters increased by 1.10% (95% CI: 0.21 to 2.00). The veterinary workload in the shelters of two counties exceeded what is regulated by law (i.e., 100 animals per veterinarian) in 2018 and increased to six counties in 2020. This current study reported important trends in the management of public animal shelters in Taiwan, the increasing workload of shelter veterinarians, and factors associated with these trends. It built the epidemiological foundation for future research on methods of improving shelter management and work conditions for shelter staff.

Management and behavioral factors associated with rehoming outcomes of dogs retired from commercial breeding kennels

Rehoming is a potentially stressful process for dogs retired from commercial breeding (CB) kennels, as they may struggle to cope with the myriad novel factors associated with transitioning to a home environment. Failure to adapt may increase the risk of an unsuccessful adoption, jeopardizing dog welfare and the benefits of rehoming programs. Little is known about relationships between welfare in the kennel of origin and a dog's ability to transition to a family home. This study aimed at investigating the welfare states of dogs retiring from CB kennels in relation to varying management practices across kennels, and understanding how behavioral and management factors might be associated with rehoming outcomes. A total of 590 adult dogs from 30 US CB kennels were included in the study. Dog behavioral and physical health metrics were collected through direct observation, while management information was obtained through a questionnaire. One month after adoption, 32 dog owners completed a follow-up questionnaire (CBARQ). A principal component analysis extracted four behavioral components (PCs) which included food interest, sociability, boldness, and responsiveness. Factors such as sex, housing, breed, and the number of dogs per caretaker were reported as significant sources of variation for some of those PC scores (p<0.05). For instance, lower dog to caretaker ratio was linked to better health, sociability, and food interest scores. Significant relationships were also found between in-kennel PC scores and CBARQ scores (p<0.05). Most interestingly, higher levels of sociability in the kennel were associated with lower levels of social and non-social fear, and higher trainability after rehoming. Overall, dogs were found to be physically healthy, and a moderate proportion showed fearful responses toward either social or non-social stimuli. Results suggest that a comprehensive behavioral assessment of rehoming candidates while in the kennel may help identify dogs that may have more difficulty coping during rehoming. The implications for developing management strategies and necessary interventions that support positive dog welfare outcomes within the kennel and when rehomed are discussed.

The impact of returning a pet to the shelter on future animal adoptions

Unsuccessful animal adoptions are stressful for many owners and may reduce their willingness to adopt again. The goal of this study was to determine the proportion of return owners who adopted post-return and investigate return characteristics that affected the likelihood of post-return adoption. We analyzed adoption records from a South Carolina animal shelter between 2015 and 2019 (n = 1999) using a logistic regression model including post-return adoption (binary) and return reason, species, animal sex and age. We found one in 10 individuals adopted from the shelter within 12 months of return, and post-return adoption was associated with return reason and species. Returns due to owner-related reasons, such as the owner’s health (OR 0.20, 95% CI 0.07, 0.57) or unrealistic expectations (OR 0.42, 95% CI 0.19, 0.94) were associated with significantly lower odds of post-return adoption. Owners who returned due to the animal’s health exhibited four times greater odds of post-return adoption compared with behavioral returns (OR 4.20, 95% CI 2.37, 7.45). Our findings highlight the value of ensuring adopters’ expectations are aligned with the reality of ownership and minimizing adopter-animal behavioral incompatibility as unsuccessful animal adoptions can reduce the owner’s willingness to adopt again and may affect the adopter’s relationship with the shelter.

Behavior Education and Intervention Program at a Small Shelter I. Effect on Behavior Knowledge and Safety

Behavior knowledge is a critical component of shelter staff and volunteer training. Canine behavior knowledge was assessed at a small shelter before and after a six-month program of educational seminars and real-time case interventions for staff and volunteers. Participants were asked to complete surveys assessing their knowledge of body language, motivation, and training methodology, as well as rank their own comfort with these topics. Staff and volunteers who participated in the program and interacted with the dogs were compared to board members (who do not interact with the dogs) and feline-only volunteers. Prior to the program, both groups demonstrated poor scores and self-assessments did not correlate with knowledge scores. Those who participated in the program were more likely to be high performers on the post-program survey, odds ratio: 1.594 (95%CI 1.10-2.137) p = 0.002. Psychometric evaluation of the survey answers themselves illustrated gaps in behavior knowledge in shelter members and suggests that both seminar and case interventions can improve this. Formalized behavior education and measurement of behavior knowledge may facilitate the mission of shelters and safety there-in.

Relinquishing Owners Underestimate Their Dog's Behavioral Problems: Deception or Lack of Knowledge?

Undesirable behavior is a leading cause of canine relinquishment. Relinquishing owners could provide valuable information about their dog's behavior, although the reliability of their reports has been questioned by the sheltering community. This study aimed to investigate (a) whether relinquishing owners' reports of dog behavior differed based on the behavioral screening method; (b) whether relinquishing owners' reports were impacted by the confidentiality of their responses; and (c) whether relinquishing and non-relinquishing owners perceived the behavior of their dogs differently. The sample included 427 relinquished dogs from three animal shelters and 427 pet dogs, matched for sex and breed. Owners responded to a direct question about whether they were experiencing problems with their dog's behavior and completed the mini C-BARQ which includes 42 questions about the frequency and severity of specific canine behaviors in various circumstances. More than two-thirds (69.3%) of relinquishing owners indicated they were not experiencing problems with their dog's behavior when asked directly, compared with only 34.5% of pet owners. Yet, relinquished dogs had significantly higher (less desirable) scores than pet dogs across most C-BARQ scales. The disparity between C-BARQ scores and the single, direct question does not appear to be the result of deliberately biased reporting by relinquishing owners as the perceived confidentiality (or lack thereof) did not affect their responses (X² = 1.44, p = 0.97). It is possible that relinquishing owners had less understanding of dog behavior and did not recognize behavior problems as a problem. Our findings support the use of standardized behavioral questionnaires, such as the mini C-BARQ, to collect behavioral information from owners at the time of relinquishment and highlight opportunities for animal shelters to reduce relinquishment by assisting owners to recognize and manage behavioral problems.

Enhancing the Selection and Performance of Working Dogs

Dogs perform a variety of integral roles in our society, engaging in work ranging from assistance (e.g., service dogs, guide dogs) and therapy to detection (e.g., search-and-rescue dogs, explosive detection dogs) and protection (e.g., military and law enforcement dogs). However, success in these roles, which requires dogs to meet challenging behavioral criteria and to undergo extensive training, is far from guaranteed. Therefore, enhancing the selection process is critical for the effectiveness and efficiency of working dog programs and has the potential to optimize how resources are invested in these programs, increase the number of available working dogs, and improve working dog welfare. In this paper, we review two main approaches for achieving this goal: (1) developing selection tests and criteria that can efficiently and effectively identify ideal candidates from the overall pool of candidate dogs, and (2) developing approaches to enhance performance, both at the individual and population level, via improvements in rearing, training, and breeding. We summarize key findings from the empirical literature regarding best practices for assessing, selecting, and improving working dogs, and conclude with future steps and recommendations for working dog organizations, breeders, trainers, and researchers.

Characterizing unsuccessful animal adoptions: age and breed predict the likelihood of return, reasons for return and post-return outcomes

A considerable number of adopted animals are returned to animal shelters post-adoption which can be stressful for both the animal and the owner. In this retrospective analysis of 23,932 animal records from a US shelter, we identified animal characteristics associated with the likelihood of return, key return reasons, and outcomes post-return for dogs and cats. Binary logistic regression models were used to describe the likelihood of return, return reason and outcome based on intake age, intake type, sex, breed and return frequency. Behavioral issues and incompatibility with existing pets were the most common return reasons. Age and breed group (dogs only) predicted the likelihood of return, return reason and post-adoption return outcome. Adult dogs had the greatest odds of post-adoption return (OR 3.40, 95% CI 2.88-4.01) and post-return euthanasia (OR 3.94, 95% CI 2.04-7.59). Toy and terrier breeds were 65% and 35% less likely to be returned compared with herding breeds. Pit bull-type breeds were more likely to be returned multiple times (X2 = 18.11, p = 0.01) and euthanized post-return (OR 2.60, 95% CI 1.47-4.61). Our findings highlight the importance of animal behavior in the retention of newly adopted animals and provide useful direction for allocation of resources and future adoption counselling and post-adoption support services.

Voices of NGOs Supporting the First Master's Degree Program in Ethology and Human-Animal Interactions in Romania: An Exploratory Qualitative Analysis

Simple Summary

The objective of this exploratory study was to investigate through a qualitative thematic analysis the reflections of six animal protection and wildlife conservation non-governmental organizations (NGOs) in Romania regarding the development of the first specialized master’s degree program in ethology and human-animal interaction in the country. The two research questions addressed in the study were (1) What are the needs of the participating NGOs that could be addressed by the first professional master’s program in ethology and human-animal interactions in Romania? (2) What are the expectations regarding the roles of the graduates of the program on the collaboration with the NGOs in addressing common problems in the area of human-animal interactions in Romania? The qualitative content analysis of the written reflections allowed the identification of two themes, which provided us valuable insights regarding the curriculum offerings and the pedagogical strategies that could respond to the expressed expectations. The first theme refers to the concerns expressed by the representatives of the NGOs over the animal welfare and human-animal interactions in Romania, which included seven categories of codes: concerns over stray animals, lack of education of general population on animal welfare and interactions with animals, maltreatment of animals, human-animal conflicts, lack of professional specializations in ethology and human-animal interactions, concerns over common global issues, and concerns over national nature conservation. The second identified theme refers to the expectations regarding the roles of the graduates of the master’s degree program, and it includes the following four categories: agents for change towards a responsible community, problem solvers, public policy-makers, and providers of competence-based expertise.

Abstract

This study aims to explore through a qualitative thematic analysis the reflections of six animal protection and wildlife conservation NGOs in Romania regarding the development of the first specialized master’s degree program in ethology and human-animal interaction (EHAI), in relation to the identified needs based on their experience in the field, as well as their expectations in terms of collaboration with the graduates of such a program in addressing the common problems in the areas of animal welfare and human-animal interactions (HAIs). The qualitative content analysis of the written reflections allowed the identification of two themes, which provided valuable insights regarding the curriculum offerings and the pedagogical strategies that could respond to the expressed needs and expectations. The first theme included seven categories of concerns expressed by the NGOs over the animal welfare and HAIs in Romania, i.e., concerns over stray animals, lack of education of general population on HAI and animal welfare, maltreatment of animals, human-animal conflicts, lack of professional specializations in HAI, concerns over common global issues, and concerns over national nature conservation. The second theme refers to the expectations regarding the roles of the graduates of the EHAI master’s program, and it includes four categories of codes: agents for change towards a responsible community, problem solvers, public policy-makers, and providers of competence-based expertise. The inclusion of Service-Learning as signature pedagogy in the EHAI program, in connection with the One Welfare approach, is discussed in relation to the needs expressed by the representatives of the NGOs.

"More Attention than Usual": A Thematic Analysis of Dog Ownership Experiences in the UK during the First COVID-19 Lockdown

On 23 March 2020, the UK Government imposed a nationwide lockdown as part of efforts to mitigate the impact of COVID-19. This study aimed to explore how the experience of dog ownership in the UK was impacted during this lockdown. Data for this research came from open-ended survey questions and an electronic diary completed by members of the general public and participants involved in "Generation Pup", an ongoing longitudinal cohort study of dogs. A total of 10,510 free-text entries were analysed. Three major themes emerged: spending time at home with dog(s), walking practices, and behaviour and training. Owners valued having more time than usual with their dog(s) but also recognised that spending extra time with their dog(s) may negatively impact on the dog's future ability to cope when left alone. However, very few owners provided alone time for their dog(s) during the lockdown. The opportunity to walk their dog(s) as part of their permitted daily exercise was regarded positively, but walks under the lockdown guidelines were not always felt to be adequate with respect to providing sufficient exercise and opportunities for interaction with other dogs. Owners reported observing new undesirable behaviours in their dog(s) during the lockdown, including barking and dogs being "clingy" or vocalising when briefly left alone. Based on these findings, we suggest intervention strategies to best support dog welfare that include helping dog owners to teach dogs to cope with being alone, even if owners do not need to leave their dogs alone.

Can This Dog Be Rehomed to You? A Qualitative Analysis and Assessment of the Scientific Quality of the Potential Adopter Screening Policies and Procedures of Rehoming Organisations

Unwanted dogs are an international problem, and rehoming organisations are tasked with finding many of them appropriate homes. Whilst the processes involved in assessing dogs' suitability for rehoming have received considerable academic attention, the policies and procedures organisations employ for screening potential adopters, which are equally as important to dogs' outcomes, appear to be largely overlooked. Therefore, the aim of this study was to conduct a qualitative analysis of rehoming organisations' adopter screening processes in order to gain insight into what is being done, the extent to which this appears to have any scientific rationale, and what other factors might be driving the process. A written enquiry was sent to organisations in the UK; topics addressed included whether they use a standardised screening process, whether they interview potential adopters and what information is gathered during the interview, and how they score responses. Information was received from 82 respondents. Pre-adoption home visits were the most commonly used method. Self-administered questionnaires were the most standardised method. Using a thematic analysis, ten themes emerged from the types of information gathered during the screening process; 31 characteristics could lead an adopter being deemed unsuitable to adopt a dog. Evidence to potentially support these was found for only eight of them in the academic literature relating to risk factors for relinquishment and human safety risk. The inclusion of some of the characteristics considered important was thought to be for the purpose of ensuring a good quality of life for a dog, but there is a lack of relevant research investigating this. Organisations seem to invest considerable resources into screening potential adopters, but there is limited scientific, and sometimes logical, rationale for this. A further concern relates to the quality of the assessment processes, which show little evidence of quality control measures. Until the necessary research is conducted, it could be argued, from a pragmatic perspective, that organisations should relax their strict screening criteria, and focus their resources on ensuring owners are fully prepared for the changes in their life associated with the inclusion of a new dog in their home and supporting them as necessary.

Abilities of Canine Shelter Behavioral Evaluations and Owner Surrender Profiles to Predict Resource Guarding in Adoptive Homes

Simple Summary

Some domestic dogs guard resources and display behaviors such as growling, snarling, or biting when approached. Most animal shelters test for food-related aggression and some consider dogs assessed as food aggressive to be unadoptable and candidates for euthanasia. We surveyed adopters of 139 dogs assessed as either resource guarding (n = 20) or non-resource guarding (n = 119) at a New York (NY) shelter to determine whether shelter identification as food aggressive was associated with guarding in adoptive homes. We also examined whether description of resource guarding in owner reports completed when surrendering a dog to the shelter predicted guarding in adoptive homes. Statistically, shelter assessment as resource guarding and owner-supplied information indicating resource guarding were each associated with guarding in adoptive homes. However, more than half of dogs either assessed by shelter staff or described by surrendering owners as resource guarding did not guard in adoptive homes. Our data indicate that information from surrendering owners, while potentially helpful, is not always predictive of a dog’s behavior in an adoptive home, and most importantly, that shelters should not consider all dogs assessed as resource guarding to be unadoptable because many of these dogs do not display guarding behavior post adoption.

Abstract

Some shelters in the United States consider dogs identified as food aggressive during behavioral evaluations to be unadoptable. We surveyed adopters of dogs from a New York shelter to examine predictive abilities of shelter behavioral evaluations and owner surrender profiles. Twenty of 139 dogs (14.4%) were assessed as resource guarding in the shelter. We found statistically significant associations between shelter assessment as resource guarding and guarding reported in the adoptive home for three situations: taking away toys, bones or other valued objects; taking away food; and retrieving items or food taken by the dog. Similarly, owner descriptions of resource guarding on surrender profiles significantly predicted guarding in adoptive homes. However, positive predictive values for all analyses were low, and more than half of dogs assessed as resource guarding either in the shelter or by surrendering owners did not show guarding post adoption. All three sources of information regarding resource guarding status (surrender profile, shelter behavioral evaluation, and adopter report) were available for 44 dogs; measures of agreement were in the fair range. Thus, reports of resource guarding by surrendering owners and detection of guarding during shelter behavioral evaluations should be interpreted with caution because neither source of information consistently signaled guarding would occur in adoptive homes.

Randomized blinded controlled clinical trial to assess the effect of oral cannabidiol administration in addition to conventional antiepileptic treatment on seizure frequency in dogs with intractable idiopathic epilepsy

OBJECTIVE

To assess the effect of oral cannabidiol (CBD) administration in addition to conventional antiepileptic treatment on seizure frequency in dogs with idiopathic epilepsy.

DESIGN

Randomized blinded controlled clinical trial.

ANIMALS

26 client-owned dogs with intractable idiopathic epilepsy.

PROCEDURES

Dogs were randomly assigned to a CBD (n = 12) or placebo (14) group. The CBD group received CBD-infused oil (2.5 mg/kg [1.1 mg/lb], PO) twice daily for 12 weeks in addition to existing antiepileptic treatments, and the placebo group received noninfused oil under the same conditions. Seizure activity, adverse effects, and plasma CBD concentrations were compared between groups.

RESULTS

2 dogs in the CBD group developed ataxia and were withdrawn from the study. After other exclusions, 9 dogs in the CBD group and 7 in the placebo group were included in the analysis. Dogs in the CBD group had a significant (median change, 33%) reduction in seizure frequency, compared with the placebo group. However, the proportion of dogs considered responders to treatment (≥ 50% decrease in seizure activity) was similar between groups. Plasma CBD concentrations were correlated with reduction in seizure frequency. Dogs in the CBD group had a significant increase in serum alkaline phosphatase activity. No adverse behavioral effects were reported by owners.

CONCLUSIONS AND CLINICAL RELEVANCE

Although a significant reduction in seizure frequency was achieved for dogs in the CBD group, the proportion of responders was similar between groups. Given the correlation between plasma CBD concentration and seizure frequency, additional research is warranted to determine whether a higher dosage of CBD would be effective in reducing seizure activity by ≥ 50%.

Social vulnerability assessment of dog intake location data as a planning tool for community health program development: A case study in Athens-Clarke County, GA, 2014-2016

A retrospective spatial analysis of dog intake data from an open admission animal shelter in Georgia was conducted to explore patterns within dog demographics and outcomes by pickup location or by the home address of the person who transferred ownership rights of the dog to Athens-Clarke County Animal Control during the period 2014-2016. Spatial analysis found the relationship between these intake locations and the final disposition of the dogs to be non-random, suggesting social and environmental influences on distribution. Statistically significant clusters were identified using the Getis-Ord Gi* statistic. This study found statistically significant hot spots (i.e., areas with higher than expected values) and cold spots (i.e., areas with lower than expected values) for the intake of dogs with known health issues, physically neglected dogs, juveniles, and adults. Only statistically significant hot spots were found for socially neglected dogs and dogs whose final disposition was euthanasia due to severe health or behavioral issues. Given the close relationship between humans and dogs, this study explores the association of impounded dog clusters and a previously developed social vulnerability index. Social vulnerability is the product of social inequalities and inequalities related to the human-built environment. The social vulnerability index provides one tool for understanding the differences in characteristics of dogs from different intake locations. Results of this study indicate the utility of non-animal focused data as a planning tool for community programs and to allow for efficient allocation of limited resources for veterinary and other community outreach programs.

Behavioral Changes in Dogs With Idiopathic Epilepsy Compared to Other Medical Populations

Anxiety related behaviors have been reported in humans diagnosed with idiopathic epilepsy (IE) and such traits may be altered depending on seizure phase. The purpose of this study was to determine the presence and severity of anxiety related behaviors in dogs with IE compared to other medical populations, and to determine if behavioral changes were associated with seizure control. In this retrospective cross-sectional study, the owners of 102 dogs presenting for wellness examination (37), epilepsy (38), and intervertebral disc disease (27) were surveyed utilizing a questionnaire developed based on the shortened Canine Behavioral Assessment and Research Questionnaire (mini-CBARQ), previously validated for its ability to analyze canine behavior. Veterinarians of participating dogs completed a questionnaire to verify diagnoses. Dogs with IE and IVDD had a higher likelihood of being fearful/anxious when approached by an unfamiliar dog compared to the wellness group. Dogs with IE receiving polytherapy had decreased excitement before a walk (P = 0.0007) or car trip (P = 0.027), increased fear/anxiety when groomed (P = 0.0197), and increased shaking, shivering, or trembling when left alone (P = 0.0004) compared to dogs receiving monotherapy. Polytherapy dogs had increased agitation when their owner/others showed affection toward other people/dogs during preictal (Pperson = 0.005, Panimal = 0.0083), postictal (Pperson = 0.001, Panimal = 0.0068), and interictal (Pperson = 0.0083, Panimal = 0.02) period compared to monotherapy dogs. Seizure frequency and severity was not correlated with anxiety related behavior in dogs with IE. While seizure phase was associated with behavior changes in 38% (14/37) of our epileptic population, one specific seizure phase was not more likely to produce behavior changes than another. Behavioral changes noted in dogs with IE raises further questions about how this disease affects QoL. Research was presented in abstract form at the ACVIM Forum, Denver, CO, USA, June 2016.

Revisiting a Previously Validated Temperament Test in Shelter Dogs, Including an Examination of the Use of Fake Model Dogs to Assess Conspecific Sociability

Simple Summary

Globally, many unwanted dogs enter rescue shelters. Shelter staff often avail of behavioural tests as an early screening tool to identify areas of concern to minimise the welfare risk associated with long-term kennelling and failed adoptions. A number of requirements need to be verified in order for a test to become a useful assessment tool, including how reliable and accurate the measurements are. For these tools to be widely used, they need to be feasible and reproducible. We refined a previously validated temperament test for shelter dogs’ assessment, developed in Italy, and applied it to two populations of shelter dogs in the UK. The test measured dog behaviour in the kennel, sociability towards people and other dogs, docility to leash, playfulness, cognitive skills, and reactivity. The test proved easy to replicate, with key outcomes that are consistent with existing research on this topic. Furthermore, an additional experiment provided support for the use of fake dogs instead of real ones to assess sociability to dogs. However, we also highlight the importance of interpreting these data with caution, and advocate the use of behavioural tests as a partial screening tool to be used in conjunction with more extensive behavioural and welfare monitoring.

Abstract

This study assessed the feasibility and reproducibility of a previously validated temperament test (TT) for shelter dogs. The test was developed to measure dog behaviour in the kennel, and traits of sociability towards people and other dogs, docility to leash, playfulness, cognitive skills, and reactivity. We introduced the use of differently sized fake dogs to check their appropriateness in correctly assessing sociability to dogs to broaden its applicability (as the original study used real stimulus dogs). We hypothesised that dogs’ responses may be modulated by the body size of the stimulus dog presented. The reduction analysis of the TT scores extracted five main dimensions (explaining 70.8% of variance), with high internal consistency (alpha > 0.65) and being broadly consistent with existing research. Behavioural components that were extracted from the fake dog experiment showed that dogs are likely to show signs of anxiety and fear toward both the real and fake dog. Dogs’ responses towards a real vs. fake stimulus were significantly correlated (p < 0.05) and they were not affected by the size of the stimulus (p > 0.05). We discuss the importance of interpreting these data with caution and use behavioural tests as a partial screening tool to be used in conjunction with more extensive behavioural and welfare monitoring.

Behavior in dogs with spontaneous hypothyroidism during treatment with levothyroxine

Background

Thyroid hormone supplementation anecdotally has been described as a valid treatment option for dogs with aggression‐related problems. However, prospective, controlled, and blinded trials evaluating behavior and neurohormonal status in hypothyroid dogs during treatment with levothyroxine are lacking.

Objective

Levothyroxine supplementation will have a significant influence on the behavior and neurohormonal status of dogs with spontaneous hypothyroidism.

Animals

Twenty client‐owned dogs diagnosed with spontaneous hypothyroidism.

Methods

This prospective study was to evaluate the behavior of dogs, which was screened at initial presentation, and after 6 weeks, and 6 months of treatment with levothyroxine (starting dosage 10 μg/kg PO q12h) using the standardized Canine Behavioral Assessment and Research Questionnaire (C‐BARQ). At each time period, circulating serotonin and prolactin (PRL) concentrations were evaluated using a commercially validated ELISA kit and heterologous radioimmunoassay, respectively.

Results

After 6 weeks of thyroid hormone supplementation, C‐BARQ scores demonstrated a significant increase in activity of hypothyroid dogs (P < .01). No significant change in any of the behavioral signs was observed after 6 months of treatment. No significant difference in circulating concentrations of serotonin (P > .99 and P = .46) and PRL (P = .99 and P = .37) were noted between the 6‐week and 6‐month periods compared with baseline.

Conclusions and Clinical Importance

The results of this study indicate increased activity of hypothyroid dogs after 6 weeks of thyroid hormone supplementation. None of the hypothyroid dogs in this cohort showed a significant change in any of the evaluated behavioral signs and neurohormonal status after 6 months of thyroid hormone supplementation.

Anthrozoology in Action: Performing Cognitive Training Paths in a Garden Shelter to Make Dogs More Suitable as Pets

The overpopulation of shelters and the increase of homeless dogs have become serious problems in many countries. One contributor to the number of both sheltered and homeless dogs is the abandonment and relinquishment of pet dogs by their owners for different reasons - in many cases depending on dogs' undesirable or problematic behaviors. Luckily, the behavioral characteristics of a dog are, to some extent, modifiable parameters. The aim of this study was to train the dogs housed in a garden shelter in Italy to become suitable as pets by becoming familiar to different tools and situations that they could encounter in a domestic setting through a customized educational path based on social and environmental enrichment. Shelters can hardly afford the expenses for administering training to dogs. The problem could be overcome by engaging the best graduating students attending referenced training schools, whose mission is to train professionals with high theoretical and practical skills. Shelters' administrators should choose referenced schools only, that teach positive training methods respectful of animals and that support the human-animal bond.

Aggression toward Familiar People, Strangers, and Conspecifics in Gonadectomized and Intact Dogs

Gonadectomy is widely used to treat and prevent behavior problems including the aggressive behavior of dogs. The aim of this study was to determine whether aggressive behavior toward familiar people, strangers, or other dogs was significantly different in dogs gonadectomized at various ages vs. intact dogs using the Canine Behavioral Assessment Research Questionnaire (C-BARQ) with multivariate analysis. Of 15,370 initial surveys, those for dogs reported to have been gonadectomized at less than 6 weeks of age or to correct a behavior problem, and those with incomplete answers to questions regarding independent or dependent variables were excluded, leaving 13,795 for the analysis of aggressive behavior toward familiar people: 13,498 for aggressive behavior toward strangers and 13,237 for aggressive behavior toward dogs. Aggressive behavior was defined (a) using mean scores for all questions on the C-BARQ for aggressive behavior (range 0–4) and (b) comparing dogs with no aggressive behavior (all questions answered 0) to dogs with moderate or severe aggression (at least one score of 2, 3, or 4). Data for intact dogs were compared with those for dogs gonadectomized at 6 months or less, 7–12 months, 11–18 months, and >18 months. Neither gonadectomy nor age at gonadectomy showed an association with aggression toward familiar people or dogs. However, there was a low but significant increase in the odds of moderate or severe aggression toward strangers for all gonadectomized dogs compared with intact dogs, but this effect was driven entirely by data for dogs gonadectomized at 7–12 months of age, which were 26% more likely to demonstrate aggression toward strangers. This large, comprehensive study of the relationships between gonadectomy and aggressive behavior in dogs demonstrates that when the many factors affecting aggressive behavior are considered, there is no evidence that gonadectomy at any age alters aggressive behavior toward familiar people or dogs, and there is only a minimal increase in aggression toward strangers. Given the increasing evidence of significant negative health effects of gonadectomy, there is an urgent need to systematically examine other means of preventing unwanted procreation, such as vasectomy and hysterectomy.

Surrenderers' Relationships with Cats Admitted to four Australian Animal Shelters

Simple Summary

The surrender of cats to animal shelters results in financial, social and moral burdens for the community. Human caretaking of cats was explored in a sample of people surrendering cats to shelters in Australia. At the shelters surrenderers classified themselves as owners or non-owners and a questionnaire identified that this was related to their method of acquisition of the cat, their association time with the cat, the closeness of their relationship with the cat and their degree of responsibility for the cat’s care. A model of ownership perception was developed to provide a better understanding of factors influencing ownership perception. Understanding ownership perceptions in cats surrendered to shelters is important as these can inform the development of more targeted and effective intervention strategies to reduce numbers of unwanted cats.

Abstract

The surrender of cats to animal shelters results in financial, social and moral burdens for the community. Correlations of caretaking and interactions with surrendered cats were calculated, to understand more about humans’ relationships with surrendered cats and the contribution of semi-owned cats to shelter intakes. A questionnaire was used to collect detailed information about 100 surrenderers’ relationships with cats they surrendered to four animal shelters in Australia, with each surrenderer classifying themselves as being either the owner or a non-owner of the surrendered cat (ownership perception). Method of acquisition of the cat, association time, closeness of the relationship with the cat and degree of responsibility for the cat’s care were all associated with ownership perception. Many non-owners (59%) fed and interacted with the cat they surrendered but rarely displayed other caretaking behaviours. However, most surrenderers of owned and unowned cats were attached to and felt responsible for the cat. Based on these results and other evidence, a causal model of ownership perception was proposed to provide a better understanding of factors influencing ownership perception. This model consisted of a set of variables proposed as directly or indirectly influencing ownership perception, with connecting arrows to indicate proposed causal relationships. Understanding ownership perception and the contribution of semi-owned cats to shelter intake is important as these can inform the development of more targeted and effective intervention strategies to reduce numbers of unwanted cats.

Development of the "Highly Sensitive Dog" questionnaire to evaluate the personality dimension "Sensory Processing Sensitivity" in dogs

In humans, the personality dimension 'sensory processing sensitivity (SPS)', also referred to as "high sensitivity", involves deeper processing of sensory information, which can be associated with physiological and behavioral overarousal. However, it has not been studied up to now whether this dimension also exists in other species. SPS can influence how people perceive the environment and how this affects them, thus a similar dimension in animals would be highly relevant with respect to animal welfare. We therefore explored whether SPS translates to dogs, one of the primary model species in personality research. A 32-item questionnaire to assess the "highly sensitive dog score" (HSD-s) was developed based on the "highly sensitive person" (HSP) questionnaire. A large-scale, international online survey was conducted, including the HSD questionnaire, as well as questions on fearfulness, neuroticism, "demographic" (e.g. dog sex, age, weight; age at adoption, etc.) and "human" factors (e.g. owner age, sex, profession, communication style, etc.), and the HSP questionnaire. Data were analyzed using linear mixed effect models with forward stepwise selection to test prediction of HSD-s by the above-mentioned factors, with country of residence and dog breed treated as random effects. A total of 3647 questionnaires were fully completed. HSD-, fearfulness, neuroticism and HSP-scores showed good internal consistencies, and HSD-s only moderately correlated with fearfulness and neuroticism scores, paralleling previous findings in humans. Intra- (N = 447) and inter-rater (N = 120) reliabilities were good. Demographic and human factors, including HSP score, explained only a small amount of the variance of HSD-s. A PCA analysis identified three subtraits of SPS, comparable to human findings. Overall, the measured personality dimension in dogs showed good internal consistency, partial independence from fearfulness and neuroticism, and good intra- and inter-rater reliability, indicating good construct validity of the HSD questionnaire. Human and demographic factors only marginally affected the HSD-s suggesting that, as hypothesized for human SPS, a genetic basis may underlie this dimension within the dog species.

Characteristics of Excitable Dog Behavior Based on Owners' Report from a Self-Selected Study

Simple Summary

This study provides information about owners’ experiences with their dogs’ excitable behavior. We found that certain daily scenarios tended to prompt excitable behavior. The majority of owners in this self-selected sample were very frustrated with their excitable dog. Many dogs in the sample had other behavior problems.

Abstract

Past research has found that excitable dog behavior is prevalent among sheltered and owned dogs and many times is a reason for canine relinquishment. In spite of its prevalence in the canine population, excitable behavior is relatively unstudied in the scientific literature. The intent of this research was to understand the experience of owners of excitable dogs through the analysis of self-administered online questionnaires completed by owners as part of another study. We found that certain daily scenarios tended to prompt excitable behavior, with excitability most common when the owner or other people came to the dog’s home. All owners experienced some level of frustration with their dog’s excitable behavior, with the majority being very frustrated. Many dogs in the sample had other behavior problems, with disobedient, destructive, chasing and barking behaviors being the most commonly reported. Other characteristics of excitable dogs also are discussed. Although the ability to generalize from these results is likely limited, due to targeted recruitment and selection of owners of more excitable dogs, this research provides valuable insights into the owner’s experience of excitable behavior. We hope this study prompts more research into canine excitable behavior which would expand our understanding of this behavior and help behaviorists, veterinarians, and shelters develop tools for managing it, as well as provide better education to owners of excitable dogs.

Comparison of SAFER behavior assessment results in shelter dogs at intake and after a 3-day acclimation period

In this study, it was hypothesized that different results would be obtained by canine behavior assessments performed within 24 hr of shelter intake (Day 0) and after a 3-day acclimation period (Day 3). Safety Assessment for Evaluating Rehoming assessments were performed on 33 dogs at 2 municipal shelters. Agreements between Day 0 and Day 3 varied among subtests, and no consistent temporal patterns were observed. Weighted kappa statistics for each subtest ranged from .28 to .78, and percentage discordance was 0% to 18%. In a 2nd analysis, subtests skipped due to serious aggression were replaced with scores corresponding to serious aggression, and missing values for the Food subtest were replaced with scores for no aggression if the dog did not eat. For subtests skipped due to severe aggression, more than 50% of the dogs had scores indicating low aggression on the other assessment. Eight of 16 dogs who did not eat on Day 0 ate on Day 3; 2 showed aggression. Until the ideal time to test can be identified, it should be based on the individual dog's welfare status, and testing of dogs showing severe stress should be avoided.

Genetics and behavior: a guide for practitioners

Phenotyping behavior is difficult, partly because behavior is almost always influenced by environment. Using objective terms/criteria to evaluate behaviors is best; the more objective the assessment, the more likely underlying genetic patterns will be identified. Behavioral pathologies, and highly desirable behavioral characteristics/traits, are likely complex, meaning that multiple genes are probably involved, and therefore simple genetic tests are less possible. Breeds can be improved using traditional quantitative genetic methods; unfortunately, this also creates the possibility of inadvertently selecting for covarying undesirable behaviors. Patterns of behaviors within families and breed lines are still the best guidelines for genetic counseling in dogs.

Evaluation of a behavioral assessment tool for dogs relinquished to shelters

The goal of the present study was to evaluate a shortened, 42-item version of the Canine Behavioral Assessment and Research Questionnaire (C-BARQ((S))) as a behavioral screening tool for dogs relinquished to animal shelters. In contrast to a previous finding, the current study found no consistent evidence that relinquishing owners gave unreliable or biased responses to the questionnaire depending on whether or not they believed that this information would be shared with shelter staff or used to evaluate dogs for adoption. Relinquishing owners' C-BARQ((S)) responses for items related to aggression and fear directed toward humans and other dogs correlated with independent subjective assessments of aggressiveness made by shelter staff (generalized linear mixed models, P<0.05, N=84 aggressive dogs, N=156 non-aggressive dogs). In addition, C-BARQ((S)) scores successfully discriminated between dogs based on their eventual outcomes (i.e., adoption or euthanasia; Generalized Linear Mixed Models, P<0.05, N=181 adopted, N=177 euthanized), indicating convergent validity. Follow-up surveys with a subset of adoptive owners (N=53) revealed significant correlations (after correction for multiple comparisons) between relinquishing and adoptive owners' C-BARQ((S)) ratings for 3 behavioral traits: stranger-directed aggression (rs=0.494, P<0.001), chewing inappropriate objects (rs=0.402, P<0.01), and urination when left alone (rs=0.421, P<0.01). Overall, the findings confirmed the value of this type of shelter intake survey instrument for screening owner-surrendered dogs for the presence of behavior problems.

The Canine Orthopedic Index. Step 3: Responsiveness testing

OBJECTIVE

To determine whether the Canine Orthopedic Index (COI) can detect changes in dogs with osteoarthritis (OA) treated with either non-steroidal anti-inflammatory drugs (NSAID) or placebo.

STUDY DESIGN

Double blind randomized placebo controlled trial.

ANIMALS

Dogs (n = 80) with OA.

METHODS

Owners completed the COI on Day 0. Dogs were administered either carprofen or placebo on days 1 through 14. Owners completed the COI again on Day 14. The change in total instrument, stiffness, gait, function, and quality of life scores were assessed between groups.

RESULTS

Dogs administered carprofen had significant decreases in the total instrument score (P = .002) as well as 3 of the 4 factor scores compared to dogs treated with placebo (stiffness score P = .015; gait score P = .001; and function score = 0.008). The change in quality of life score was not significantly different between carprofen and placebo treated dogs (P = .124).

CONCLUSIONS

The COI delivered the decreases in total instrument, stiffness, gait, and function scores that one would expect in dogs with OA treated with an NSAID compared with placebo administration. In this cohort of dogs, the quality of life score was not sensitive to the changes associated with NSAID administration.

The Canine Orthopedic Index. Step 2: Psychometric testing

OBJECTIVE

To perform psychometric testing an owner self-administered questionnaire, the Canine Orthopedic Index (COI), designed to assess outcome in dogs with orthopedic disease.

STUDY DESIGN

Original study.

SAMPLE POPULATION

Owners (n = 20) of dogs with osteoarthritis (OA) for item (question) pretesting, and 80 owners of dogs with OA for reliability and validity testing.

METHODS

Standard methodology for the stepwise development and testing of instruments designed to assess subjective states was followed. Items generated in previous studies were pretested for readability, ambiguity, and inter-item correlations; poorly performing items were removed; and the reduced set of items subjected to factor analysis, reliability, and validity testing.

RESULTS

Four factors were identified and named on the basis of the items contained in them: "Stiffness," "Gait," "Function," and "Quality of Life." Cronbach's α ranged from 0.76 to 0.86, suggesting the items in each factor could be assessed as a group to compute factor scores (i.e., stiffness, gait, function, and quality of life scores). The test-retest analysis revealed κ values from 0.68 to 0.80. Overall, the scores amongst the 4 factors correlated moderately well (r = 0.52-0.58), with a mild correlation (r = 0.35) between gait and function scores.

CONCLUSIONS

The COI is a psychometrically sound owner completed instrument that can assess 4 domains in dogs with OA: Stiffness, Gait, Function, and Quality of Life.
