Comparing standard screening questionnaires of canine behavior for assessment of cognitive dysfunction

BackgroundCanine cognitive dysfunction (CCD) is a common, yet underdiagnosed neurodegenerative disease affecting older dogs. Treatment is most effective when started early, so identifying mild cognitive decline in the earlier stages of the disease is considered important.Hypothesis/objectiveTo compare the results of three different standard screening questionnaires [Canine Dementia Scale (CADES), Canine Cognitive Assessment Scale (CCAS), and Canine Cognitive Dysfunction Rating Scale (CCDR)] for CCD diagnosis. Trainability, pain sensitivity, and fear were additionally assessed with the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) in order to evaluate associations between the three dementia scales and behavior.MethodsAn online survey containing all the mentioned questionnaires was designed for and distributed among owners of elderly dogs.ResultsData from 597 dogs were analyzed. Overall, the scores of the three CCD questionnaires correlated well with each other, especially those of the CADES and CCAS. The CADES was more sensitive in identifying dogs with already mild to moderate cognitive impairment, while the others classified them as still undergoing normal aging. CCD scores increased for all questionnaires with age with spatial orientation being a key feature in CCD development. Trainability assessed with the C-BARQ decreased significantly with severity of CCD signs, while pain sensitivity increased. Fear and anxiety was pronounced in animals with mild but not with severe CCD. These associations based on the C-BARQ were more clearly observable in relation to CADES and CCDR than CCAS.Conclusion/clinical relevanceThe choice of screening questionnaire impacts the evaluation of cognitive status and severity of CCD. Thresholds for severity classification differ significantly and may have an impact on reliable assessment. Further longitudinal studies are required to determine which of the questionnaires investigated in this study is best suited for early detection of CCD.

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.

A preliminary analysis of the effect of individual differences on cognitive performance in young companion dogs

Many factors influence cognitive performance in dogs, including breed, temperament, rearing history, and training. Studies in working dog populations have demonstrated age-related improvements in cognitive task performance across the first years of development. However, the effect of certain factors, such as age, sex, and temperament, on cognitive performance in puppies has yet to be evaluated in a more diverse population of companion dogs. In this study, companion dogs under 12 months of age were tested once on two tasks purported to measure aspects of executive function: the delayed-search task (DST) and the detour reversal task (DRT). Owners also filled out the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) to evaluate how temperament influenced task performance. Contrary to prior research, performance did not improve with age on either task. However, the lack of age effects was likely the result of small sample sizes and individual differences across other factors influencing performance. Specifically, temperament differences as measured by the C-BARQ subscales for nonsocial fear and excitability predicted task performance on the DST, but the effect of temperament on task performance differed between males and females. Excitability also predicted performance on the DRT, but the effect depended on the age of the dog. In addition, no correlations were observed between task measures, indicating a lack of construct validity. Overall, these findings provide a preliminary analysis of factors that appear to influence cognitive task performance in young companion dogs and highlight suggestions for future research evaluating the impact of individual differences on cognitive performance.

Digitally-enhanced dog behavioral testing

Behavioral traits in dogs are assessed for a wide range of purposes such as determining selection for breeding, chance of being adopted or prediction of working aptitude. Most methods for assessing behavioral traits are questionnaire or observation-based, requiring significant amounts of time, effort and expertise. In addition, these methods might be also susceptible to subjectivity and bias, negatively impacting their reliability. In this study, we proposed an automated computational approach that may provide a more objective, robust and resource-efficient alternative to current solutions. Using part of a ‘Stranger Test’ protocol, we tested n = 53 dogs for their response to the presence and neutral actions of a stranger. Dog coping styles were scored by three dog behavior experts. Moreover, data were collected from their owners/trainers using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ). An unsupervised clustering of the dogs’ trajectories revealed two main clusters showing a significant difference in the stranger-directed fear C-BARQ category, as well as a good separation between (sufficiently) relaxed dogs and dogs with excessive behaviors towards strangers based on expert scoring. Based on the clustering, we obtained a machine learning classifier for expert scoring of coping styles towards strangers, which reached an accuracy of 78%. We also obtained a regression model predicting C-BARQ scores with varying performance, the best being Owner-Directed Aggression (with a mean average error of 0.108) and Excitability (with a mean square error of 0.032). This case study demonstrates a novel paradigm of ‘machine-based’ dog behavioral assessment, highlighting the value and great promise of AI in this context.

Comparison between the canine behavioral assessment and research questionnaire and monash canine personality questionnaire – Revised to predict training outcome in apprentice assistance dogs

Ratings of canine behaviour and personality are a convenient method used by dog training organisations to gather information about prospective and trainee dogs. The objective of this study was to compare the use of two rating questionnaires to predict training outcomes in assistance dogs. It was of interest to investigate the predictive power of a questionnaire answered by the dog trainer in case no puppy raiser questionnaire was available. Two standardised ratings were used, in particular, the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) was completed by puppy raisers around the time the dogs started formal training and the Monash Canine Personality Questionnaire - Revised (MCPQ-R) was completed by dog trainers at ten weeks of training. Rating data were independently analysed to investigate their relationship with training outcomes. The results from the univariate logistic regression analysis were used to select the variables for the reduced feature sets that were used for modelling. The novel machine learning models built with data collected using the C-BARQ and MCPQ-R achieved similar performance in predicting training outcomes, an area under the ROC curve of 0.84 and 0.85, respectively. The novel models developed in this research were the most effective early prediction of suitability for assistance work compared to previously reported studies. The MCPQ-R was demonstrated for the first time to be a reliable canine behavioural assessment method for estimating future outcomes in trainee dogs. The dataset and code used are publicly available on GitHub.

The validation of Thai version of Canine Behavioral Assessment and Research Questionnaire (C-BARQ) and the exploration of dog ownership in Thailand

C-BARQ (Canine Behavioral Assessment and Research Questionnaire) is one of the effective and well-known tools to evaluate dog behavior by owners through a questionnaire. The C-BARQ has been translated into several languages and is used in many countries. The present study aimed to translate and adapt the English version of C-BARQ to the Thai version and validate it regarding the guidelines of cross-cultural adaptation. The C-BARQ was translated into the Thai language and translated back to English. The validation of the Thai C-BARQ was done by 40 dog owner volunteers before releasing the Thai C-BARQ online version via social media advertising for 3 months. According to demographic data, women were the majority of dog owners in Thailand (88.34%), and one-third of respondents (30.16%) lived in Bangkok, the capital city. Thai dogs mostly lived in detached houses (79.93%) and were fed conventional diet (66.83%). The majority (37.99%) of the dog owners were in the adult age group (31–40 years old). Male and female dog populations were almost equal (54.13%: 45.87%) and half of the dogs were neutered (50.63%). By factor analysis, 12 factors with 63 items were identified from the C-BARQ data of 1,827 dog owners. All factors of the Thai version of C-BARQ have acceptable reliability with the coefficient of Cronbach’s alpha values ranged between 0.697 and 0.938. Thus, the validation of Thai version of C-BARQ in the present study could be a dependable and applicable tool for assessing dog behavior in Thailand.

Factors associated with pet dog behavior in Thailand.

Dog behavior problems pose serious public health and economic and animal welfare concerns. There are many factors influencing dog behavior. This study aims to explore factors associated with pet dog behavior in Thailand using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ). The Thai version of the C-BARQ was validated in 2022. The online C-BARQ survey (Google Forms) was advertised and distributed on social media for 3 months. There were a total of 1827 respondents to the survey. The relationship among 12 subscales and variables was analyzed using Spearman's correlation. "Excitability," "attachment- and attention-seeking," and "chasing" were the three most reported behavior problems. "Trainability," a favored dog behavior, also had a high score in the study. These behaviors were associated with the owner's age, house type, the dog's historical background, the number of dogs and the presence of other species in the household, the dog's training, diet types, and the daily number of meals. The lowest mean score was for "owner-directed aggression," and it was associated with the dog's gender and size, the number of dogs and the presence of other species in the household, the dog's training, and the number of daily meals. This is the first empirical study demonstrating factors related to dog behavior in Thailand. It provides an in-depth understanding of the prevalence and factors associated with Thai pet dog behavior and important knowledge for further studies to advocate for dog-human relationships and contribute to a reduction in dog abandonment in Thailand.

Canine Behavioral Assessment and Research Questionnaire (C-BARQ): Validation of the Italian Translation.

The aim of this study is to develop an Italian translation of the 100-item Canine Behavioral Assessment and Research Questionnaire (C-BARQ) version and to validate its psychometric properties, in order to facilitate systematic, large-scale studies on dog behavior for Italian-speaking dog owners. A total number of 803 responses by dog owners were collected online. Using the Principal Axis Method and Common Factor Analysis with Quartimin oblique rotation (p < 0.05), a factorial structure was found including 13 factors composed of 62 items and explaining 53.5% of the total variance. Eight factors showed high reliability (Cronbach's alpha > 0.70), namely: stranger-directed aggression/fear, dog-directed fear, owner-directed aggression, separation-related behavior, chasing, dog-directed aggression, attachment/attention seeking, and elimination problems. Three factors were slightly under the threshold and two had only modest reliability (non-social fear, energy level, touch sensitivity, excitability and trainability). A potential explanation for factors with low reliability is that the composing items do not describe behaviors resulting from homogeneous stimuli or situations. Although our factorial structure resembled in most respects that of the most recently published Canadian version, some important exceptions are present regarding dog rivalry, intraspecific aggression, fear/aggression towards strangers, touch sensitivity and chewing inappropriate objects. Such differences may be due to demographic and/or cultural differences between the sampled populations. Overall, the results suggest that a 62-item Italian C-BARQ can be reliably used in studies on dog behavior.

Former laboratory dogs' psychological and behavioural characteristics

It is becoming increasingly common for laboratories to allow the rehoming of dogs when they are no longer needed. There is no research, however, comparing the characteristics of dogs from laboratories to dogs acquired from more traditional sources for pets. This study used the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) to compare emotional and behavioural characteristics of 100 former laboratory Beagles who were rehomed to a convenience sample of 244 pet Beagles with no known history of laboratory use. Our results revealed that the former laboratory Beagles exhibited increased fearfulness, attention and attachment behaviours, and more abnormal behaviours than the convenience sample, yet were significantly less aggressive, and likely to chase other animals or escape. Importantly, we also found no significant differences in a majority of the everyday behaviours assessed. Our findings demonstrate dogs rehomed from laboratories form strong bonds with their caregivers, and make equally good companions as their non-laboratory counterparts. Our findings may be helpful in designing appropriate rehabilitation programmes, educating laboratory workers and potential adopters, and support the ongoing efforts to offer these dogs for adoption.

Relationships among morphological, environmental, social factors and aggressive profiles in Brazilian pet dogs

Pet dog aggression concerns both dogs and owners’ wellbeing and their relationship, since nowadays owners work to guarantee proper conditions for their dogs’ wellbeing, and to have a healthy emotional relationship with them. Aggressive behaviours often fall under the category of ‘undesired’ behaviours since they are mostly associated with negative contexts and possible bites or attack incidents. However, aggression remains an important component of dogs’ behavioural development, relying on communicative skills, and must be regarded as such if we want to understand how, why, and when it occurs in pet dogs. This study contributed to the ongoing investigation of how aggressive behaviour expression is affected by morpho-physiological, social, and physical environmental factors of dogs. We investigated aggression incidence and dog related factors through questionnaires applied to dog owners. Two questionnaires developed by our team were used to investigate dog, environment, and owner descriptive factors. To investigate aggression, we applied together the Canine Behavioural Assessment and Research Questionnaire (C-BARQ). Dog and owner factors, and dog aggression data scores were associated through logistic regressions. Our results indicate that features such as the dog’s weight, skull morphology and sex, and socio-environmental proprieties like their owners’ gender and age, training regimen and household habitat, significantly affected the probabilities of complete absence or significant incidence of highest aggression in urban Brazilian domestic dogs. On the other hand, aggression was not associated to the Body Mass Index (BMI), a measure used in this study to represent the dog’s size. Rather than determining aggression to a single factor common to the species or specific breeds, our results reinforce how individual behaviour, combined with dogs’ unique genetics, physiology, life experiences and environmental contexts interact throughout development to produce the observed expression patterns.

Efficacy and safety of standardized Ashwagandha (Withania somnifera) root extract on reducing stress and anxiety in domestic dogs: A randomized controlled trial

Ashwagandha (Withania somnifera) is the most revered botanical in Ayurvedic medicine. It has been traditionally used to reduce stress and enhance overall well being in humans. This study aimed to investigate the adaptogenic effects of an Ashwagandha root extract in domestic dogs (Canis familiaris). In this 4-week, randomized, double-blind, placebo-controlled study, 24 dogs experiencing stress and anxiety received either placebo or 15 mg/kg bodyweight of Ashwagandha root extract once daily. Outcome measures included urine cortisol to creatine ratio (UCCr), Canine Behavioral Assessment and Research Questionnaire (CBARQ), Canine Brief Pain Inventory scale (CBPI), and Body condition score (BCS). Based on the data collected from all the dogs, Ashwagandha root extract supplementation was associated with significant improvements in stress-related signs. In comparison with the placebo, Ashwagandha intake was associated with a statistically significant reduction in urine cortisol to creatine ratio (P = 0.0005). Results from CBARQ revealed that Ashwagandha intake was associated with a statistically significant reduction in the fear and anxiety domain (P = 0.03), compared to placebo. There was also a statistically significant reduction in the CBPI pain severity (P < 0.0001) and pain interference (P < 0.0001) domains, compared to the placebo group. Ashwagandha intake was well tolerated in all the dogs with no reported adverse events. In conclusion, the intake of Ashwagandha root extract for 4 weeks was associated with significant reductions in UCCr, and signs of fear and anxiety and pain interference.

Study of Behavioural Traits in Can de Palleiro (Galician Shepherd Dog).

Simple SummaryThe Can de Palleiro or Galician shepherd is a canine breed that was in danger of extinction but is currently growing rapidly in popularity. In this study, different behavioural traits of the breed were evaluated in order to assess breeds, select the best breeding animals and identify behaviour problems. This is the first study carried out in the Can de Palleiro breed using different scientifically validated tests. Questionnaires filled by the owners (C_BARQ) were collected, and a behavioural test (SAB) was conducted to evaluate the response of the dogs to a specific stimulus at a certain time and in a certain environment. In addition, the results from the Can de Palleiro breed were compared with those obtained from the general canine population of Galicia. Thereby, the Can de Palleiro breed showed less owner-directed aggression, dog-directed fear, excitability, non-social fear and separation-related problems and better trainability.The Can de Palleiro (CP) is an autochthonous canine breed from Galicia (NW Spain). Interestingly, no previous research has been published about the behaviour of this breed. Thus, the aim of the present study was to obtain a deeper understanding of CP behavioural and temperamental traits and detect any potentially problematic behaviour by using the Canine Behavioural Assessment and Research Questionnaire (C-BARQ) and the Socially Acceptable Behaviour (SAB) test. Behavioural information was obtained from 377 dogs—177 CPs and 200 general population (GP) dogs—using the C-BARQ. Additionally, 32 dogs were enrolled to perform the SAB test (19 CPs and 13 GP dogs) in order to directly evaluate their temperament. Our results indicated that CP dogs had a lower tendency to show aggressiveness towards their owners (0.18 times lower, p = 0.033) and less fear of other dogs (by 0.43 times, p = 0.001), as well as higher trainability levels (2.56 times higher, p < 0.001) when compared to GP dogs. CP dogs also had increased odds of showing chasing behaviour (3.81 times higher, p < 0.001). Conversely, CPs had reduced odds of non-social fear, separation-related problems and excitability (by 0.42, 0.35 and 0.48 times, respectively; p < 0.001, p < 0.001 and p = 0.002). The current research represents a starting point for the study of the behaviour of CPs, which appear to be a working breed, with guarding and, especially, herding characteristics.

Validation of a Behavior Test for Predicting Puppies' Suitability as Detection Dogs.

Simple SummaryThe ability to predict a puppy’s future working success is important for working dog programs to maximize the number of dogs placed in service and allocate resources to puppies most likely to succeed. This study evaluated the utility of a behavioral test for candidate detection dog puppies. Agreement between scores from different observers was high; demonstrating the reliability of the test. Scores based on dogs’ performance in the test were also consistent with scores derived from questionnaires completed by the dog’s trainers; demonstrating the validity of the test’s measures. Finally; puppies’ performance in the test predicted future selection as a working dog as early as three months of age. The results indicate that the behavioral test is useful for evaluating the potential success of detection dog puppies.Behavioral characteristics are the most influential factor in the success of a working dog. The need for highly capable detection dogs continues to rise; but reliable methods for early selection are lacking. The current study aimed to assess the reliability and validity of a behavioral test for assessing detection dog suitability. A cohort of candidate detection dog puppies (n = 60) were tested at 3; 5; and 11 months of age; as well as at the completion of training at approximately one year. Tests were designed to assess important detection dog behavioral characteristics such as search ability and fearfulness. Inter-rater reliability was high between independent observers. Convergent validity was demonstrated by comparing Principal Component Analysis (PCA) scores from the behavior test to trainer ratings using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) and a survey of detection dog traits. Performance on the behavior test predicted adult selection as a detection dog as early as 3 months. The methods reported will be valuable for improving selection measures and enhancing collaborations across breeding programs in order to increase the availability of highly capable detection dogs.

Owner-Reported Attachment and Behavior Characteristics of New Guinea Singing Dogs Living as Companion Animals

ABSTRACT Domestic dogs are terrific companions in a variety of contexts. However, not all dogs have followed the same trajectory regarding domestication. In fact, little is known about how some dogs, including New Guinea singing dogs (NGSDs), fare as companion animals. The majority of NGSDs in the United States and Canada live as companion animals, yet observational studies of NGSDs have been limited to those living in zoos and in the wild. To learn more about NGSDs kept as companion animals, we compared housing and husbandry practices for NGSDs (n = 55) with those of dogs belonging to five primitive Fédération Cynologique Internationale (FCI) subgroups (n = 1,101). We also compared behavioral traits of NGSDs and dogs belonging to the FCI subgroups using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ), and their relationships with their owners using the Lexington Attachment to Pets Scale (LAPS). NGSDs differed from dogs belonging to some FCI subgroups on several C-BARQ measures. For instance, NGSDs showed greater fear than dogs in some subgroups and were more likely to urinate on objects than dogs in all subgroups. The latter finding might explain why a higher percentage of NGSDs than primitive breed dogs were housed outdoors. Nonetheless, NGSD owners scored just as highly on the LAPS as owners of other primitive dogs. Our findings suggest that NGSD owners may adapt their expectations and husbandry strategies to account for some of the behavioral differences between NGSDs and other dogs.

Characteristics associated with behavior problems in Brazilian dogs

The current study investigated associations between behavioral problems in Brazilian dogs and the demographic characteristics of both the dogs and their owners, as well as the quality of owner-dog relationship. Although Brazil has a large population of dogs, little is known about their behavioral profiles and to what extent they are comparable to those of other cultures. For this investigation, we developed a Portuguese language version of the C-BARQ (Canine Behavioral Assessment and Research Questionnaire) and evaluated its psychometrics properties, since it provides a broad and quantitative description of dog behavior, and has been widely validated across multiple countries. A convenience sample of 1741 owners completed the final questionnaire, and Exploratory and Confirmatory Factor Analyses were used to extract and confirm a 12-factor solution with excellent reliability characteristics. We then applied logistic regression models to investigate which owners’ and dogs’ characteristics, as well as characteristics of their relationships, were associated with the higher scores of behavior problems based on Brazilian C-BARQ data. Important associations were observed. Owner’s gender (female) was found to be associated with separation-related problems in dogs, as well as fear of other dogs, attention-seeking behavior, excitability, and energy. Mixed-breed status (unknown breed) was associated with more aggression towards other dogs, fear of strangers and other dogs, nonsocial fear, and separation-related problems. Aggression towards strangers and attention-seeking behaviors were exhibited more often by those dogs that were not walked by their owners. Our results revealed relevant aspects influencing dog behavioral problems and emphasizes the importance of evaluating dog behavior problems in light of cultural influences.

Concurrent and Predictive Criterion Validity of a Puppy Behaviour Questionnaire for Predicting Training Outcome in Juvenile Guide Dogs

Simple SummaryThe ability to predict later success in guide dog training can be of great benefit to assistance dog providers, such as those providing guide dogs, to ensure maximum resource and production efficiency and to maintain high welfare standards. This study evaluated the predictive capabilities of a behaviour questionnaire (the refined puppy walker questionnaire, r-PWQ) completed by volunteer carers of puppies (puppy walkers) for dogs aged eight months of age. The r-PWQ includes traits such as “Distractibility” and “Excitability”, which are common withdrawal reasons for many guide dogs. The predictive validity of the r-PWQ was compared to a well-known behaviour questionnaire, (Canine Behavioral Assessment and Research Questionnaire—C-BARQ). The results show that the r-PWQ can be used to predict guide dog outcome and may be better suited to guide dog populations than the C-BARQ.Working dog organisations regularly assess the behaviour of puppies to monitor progression. Here, we tested the predictive validity (for predicting success in guide dog training) of a shortened version of a previously developed juvenile dog behaviour questionnaire (the refined puppy walker questionnaire, r-PWQ) and compared it with the Canine Behavioral Assessment and Research Questionnaire (C-BARQ). The r-PWQ is used by Guide Dogs UK, whereas the C-BARQ was designed for pet dogs and is used by some other guide dog schools internationally. A cohort of dogs aged eight months (n = 359) were scored concurrently on the r-PWQ and C-BARQ. Analogous traits between the questionnaires were evaluated for internal consistency and association with training outcome and compared for concurrent validity. The r-PWQ was associated with training outcome for five scales (r-Excitability, Trainability, Animal Chase, r-Attachment and attention seeking and Distractibility) and the C-BARQ for two scales (Excitability and Separation-related behaviour). There were significant correlations between analogous C-BARQ and r-PWQ trait scores (p < 0.001) except for Separation-related behaviour and questionnaire scales had similar internal consistencies. The r-PWQ may be more suitable to use with guide dog schools. However, due to the correlation between analogous scales (except for “Distractibility”) some scales could be substituted for one another when reviewing the behaviour of dogs between guide dog schools using different questionnaires.

Comparison of Canine Behaviour Scored Using a Shelter Behaviour Assessment and an Owner Completed Questionnaire, C-BARQ.

Simple SummaryIn shelters, it is usual to conduct a standardised behaviour assessment to identify adoption suitability. The information gathered from the assessment is used to identify the behaviour of the dogs, suitability for adoption and to help to match the dog to an ideal home environment. We investigated if the dogs’ behaviour in the home as reported by owners was reflected in the Royal Society for the Prevention of Cruelty to Animals (RSPCA) Queensland behaviour assessment, conducted on the same dogs during a visit to the shelter. A total of 107 owners and their dogs aged 1–10 years were assessed in-home, by the owners, and in the shelter, by a researcher. The owners completed a questionnaire (Canine Behavioural Assessment and Research Questionnaire (C-BARQ)) prior to the standardised behavioural assessment conducted at the RSPCA Queensland. Regression analysis identified positive correlations between the two for fear, arousal, friendliness and anxiousness, identified in in-home behaviour and the behaviour assessment. This research therefore allowed a greater understanding of current canine behaviour assessment protocols used at the RSPCA Queensland in regard to the predictability of behaviour, behavioural problems and the efficiency and effectiveness of testing procedures.In shelters, it is usual to conduct a standardised behaviour assessment to identify adoption suitability. The information gathered from the assessment is used to identify the behaviour of the dogs, its suitability for adoption and to match the dog with an ideal home environment. However, numerous studies have demonstrated a lack of predictability in terms of the post-adoption behaviour in these assessments. We investigated if the owners’ perception of dogs’ behaviour in the home was reflected in the RSPCA Queensland behaviour assessment, conducted on the same dogs during a visit to the shelter. A total of 107 owners and their dogs aged 1–10 years were assessed in-home and in the shelter. The owners of the dogs completed a questionnaire (the Canine Behavioural Assessment and Research Questionnaire (C-BARQ) survey) 1–2 weeks before bringing their dog to the shelter for the standardised behavioural assessment conducted at the RSPCA Queensland. An ordinal logistic regression analysis identified positive correlations for fear, arousal, friendliness and anxiousness, identified in in-home behaviour and the behaviour assessment. Furthermore, the behaviours of friendliness, fearfulness, arousal, anxiousness, and aggression were positively predictive between home behaviour and tests in the behaviour assessment. This research therefore led to a greater understanding of current canine behaviour assessment protocols used at the RSPCA Queensland in regard to the predictability of behaviour, behavioural problems and the efficiency, effectiveness and predictability of current behaviour testing procedures.

Expression of Behavioural Traits in Goldendoodles and Labradoodles.

Simple SummaryCrossbred dogs are gaining in popularity with the general public, but we do not fully understand how these crossbreds behave compared to their parent breeds in regard to inherited behaviour traits. Because of this, we investigated behaviours exhibited by crossbred dogs by focusing on the popular Goldendoodle and Labradoodle crossbreds by comparing them to their corresponding parent or constituent breeds: Standard or Miniature Poodle, and Golden Retriever or Labrador Retriever. The data for this study was provided by 5141 volunteer dog owners from across the world who filled out the Canine Behavioural Assessment and Research Questionnaire (C-BARQ) online survey. The survey results were used to analyse fourteen different representative behavioural trait scores. As expected from a first-generation crossbred (F1), the crossbreds in our study tend to fall between the two parent breeds with some exceptions. The Goldendoodle displayed more problematic behaviour when compared to its constituent breeds, whereas the Labradoodle only differs significantly from the Miniature Poodle in dog rivalry. These results can help advise future dog owners on behavioural trends for particular crossbreds.As crossbred dogs gain in popularity, how they express inherited behaviour traits in comparison to their purebred constituent breeds is of interest. We investigated behaviours exhibited by crossbred dogs by focusing on the popular Goldendoodle and Labradoodle crossbreds and comparing them to their corresponding constituent breeds: Standard and Miniature Poodle, Golden Retriever or Labrador Retriever. The data for this study was provided by 5141 volunteer dog owners who filled out the Canine Behavioural Assessment and Research Questionnaire (C-BARQ) online survey. The survey results were used to analyse breed differences in fourteen representative behavioural trait scores: trainability, stranger-directed aggression, owner-directed aggression, dog-directed aggression, dog rivalry, dog-directed fear, stranger-directed fear, non-social fear, touch sensitivity, separation-related problems, excitability, attachment/attention-seeking behaviours, energy and chasing. As expected from a first-generation crossbred (F1), the crossbreds in our study tend to fall between the two constituent parent breeds with some exceptions. Our results suggest that the F1 Labradoodle differed significantly from one of the pure constituent breeds only in dog rivalry, whereas the F1 Goldendoodle behaviour varied from one or more pure constituent breeds in dog rivalry, dog-directed aggression, dog-directed fear, and stranger-directed fear. These results can help advise future dog owners on behavioural trends for particular crossbreds.

Behavioural risks in female dogs with minimal lifetime exposure to gonadal hormones.

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire and spayed dogs, of which 12 were associated with PLGH and 5 with age-at-spay (AAS). Two behaviours, chewing and howling, were significantly more likely in dogs with longer PLGH. In contrast, longer PLGH was associated with significantly reduced reporting of 10 (mostly unwelcome) behaviours. Of these, one related to fearfulness and three to aggression. The current data suggest that dogs’ tendency to show numerous behaviours can be influenced by the timing of spaying. They indicate how female dog behaviour matures when gonadal hormones are allowed to have their effect. The differences reported here between undesirable behaviours of spayed and entire dogs were in the range of 5.33% and 7.22%, suggesting that, for some dogs, partial or complete denial of maturation may reduce howling and chewing and improve retrieval and recall, but have other undesirable consequences. Veterinarians may take these data into account to discuss the risks and benefits of spaying with clients, and the timing of the procedure.

Evaluating Cognitive and Behavioral Outcomes in Conjunction with the Secure Base Effect for Dogs in Shelter and Foster Environments.

Simple SummaryAttachment relationships formed early in life have important implications for long-term social and behavioral outcomes for humans. Although previous research has established that dogs and humans form attachment relationships that can be categorized into attachment styles, the implications of these relationships have not been well-studied. This is a particularly important area of study for dogs living in foster homes and animal shelters, as it is currently unknown if and how attachment relationships formed in these environments correspond with behavioral and cognitive outcomes. In this study, we examined attachment styles in relation to cognitive measures and surveys of canine behavior and personality completed by caretakers of dogs in foster and shelter environments. Foster dogs with secure attachments displayed higher levels of persistence and performance on cognitive tasks compared to foster dogs with insecure attachments. On a survey given to foster and shelter volunteers, we found that securely attached dogs were rated as less neurotic than insecurely attached dogs for both foster and shelter groups. These results indicate that attachment relationships are associated with other important behavioral and cognitive traits of foster and shelter dogs, suggesting that the potential for causal associations should be explored further.Although it is widely accepted that dogs and humans form attachment relationships, characterizing attachment styles in dogs has only recently received attention in the literature. Previous research has shown that pet dogs display patterns of behavior in an attachment test that can be classified into secure and insecure attachment styles, much like human children and their caretakers. However, we currently know relatively little about the role of attachment styles in relation to canine well-being. This question may be of particular interest for the 3.9 million dogs that enter animal shelters in the United States alone each year, as this transition marks the dissolution of prior bonds and the establishment of new attachment relationships. Herein, results are presented from analyses of volunteer-reported canine personality and behavior measures, as well as performance on two cognitive tasks as they relate to attachment styles developed within shelter and foster environments. Results from the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) indicated that foster dogs were scored as having significantly higher levels of attachment and attention-seeking behaviors when compared with shelter dogs. In both environments, dogs categorized as securely attached to a shelter or foster volunteer had lower neuroticism scores. Secure attachment in foster homes was also associated with improved persistence and performance on a point following task. These results provide support for the idea that attachment styles formed with temporary caregivers is associated with other behavioral and personality measures, and therefore may have implications for behavior and welfare in dogs living in foster homes and animal shelters.
