Conditions of pet rabbit breeding colonies and breeder practices are undocumented and very little is known about the pet rabbit sales market. Here, multiple methods were employed to investigate this sector of the UK pet industry. A freedom of information request sent to 10% of councils revealed confusion and inconsistency in licensing conditions. D...
Canine atopic dermatitis (cAD) is a common hereditary clinical syndrome in domestic dogs with no definitive diagnostic tests, which causes marked morbidity and has a high economic impact internationally. We created a novel questionnaire for Labrador (LR) and Golden retriever (GR) owners to evaluate canine skin health with respect to clinical signs...
Definition:
The stage in human and nonhuman animal development through which a juvenile becomes a reproductively and behaviorally mature adult.
Introduction:
Adolescence is a developmental stage in an animal’s life history that is characterized by both reproductive and behavioral maturation. The terms “puberty” and “adolescence” are often used int...
Dogs exposed to aversive events can become inactive and unresponsive and are commonly referred to as being "depressed", but this association remains to be tested. We investigated whether shelter dogs spending greater time inactive "awake but motionless" (ABM) in their home-pen show anhedonia (the core reduction of pleasure reported in depression),...
Early life experiences are known to influence behavior later in life. In dogs, environmental influences of early home rearing could be exploited to improve the chances of developing adult behavior most suited to the adult environment. For working dog organisations, such as Guide Dogs, suitable adult behavior is important to ensure dogs can fulfil t...
Owners’ understanding of dog behaviour influences dog welfare. This study aimed to investigate owners’ experiences of living with dogs and perceptions of dog behaviour/behaviour change. Data from an ongoing UK/ROI longitudinal study of dogs were used. Open-ended survey data (n = 3577 comments, n = 1808 dogs) when dogs were 12/16 weeks (data combine...
Canine atopic dermatitis is an inflammatory skin disease with clinical similarities to human atopic dermatitis. Several dog breeds are at increased risk for developing this disease but previous genetic associations are poorly defined. To identify additional genetic risk factors for canine atopic dermatitis, we here apply a Bayesian mixture model ad...
This study has identified the four most reported owner-perceived problem behaviours in dogs aged 6, 12 and 18 months. These findings can help inform where specific training strategies and interventions are needed to target these problems and prevent their development which could impact on dog welfare and the human-animal bond. Future work will expl...
As part of a population management strategy for a troop of Guinea baboons (Papio
papio) at Yorkshire Wildlife Park, adult females were given a Suprelorin contraceptive
implant. There was no information on the effect of contraception on behavior in this
species, so behavioral data were collected before and after implant placement to
determine any im...
Dogs play an important role in many western societies, providing companionship, emotional support, and assistance, as well as other more specialist roles. The literature reveals that many human–animal interaction (HAI) questionnaires exist to measure the human–dog bond (HDB). The first part of this study assessed how far existing questionnaires wen...
Separation-related behaviours (SRBs), including but not limited to vocalisation, pacing, destruction and toileting, occur in the absence of human company. As well as being problematic for the dogs’ owners, such behaviours indicate that the dogs’ emotional state is compromised. As part of the COVID-19 pandemic, time spent alone decreased considerabl...
This paper outlines the main points to consider when conducting a reliability study in the field of animal behaviour research and describes the relative uses and importance of the different types of reliability assessment: inter-rater, intra-rater and test-retest. Whilst there are no absolute methods under which reliability studies should be analys...
APPENDIX I: Tools for the measurement of HAI published between 2009-2018.
Behavioral development is a lifelong process where cognitive traits such as learning and memory may be expected to take quadratic or linear trajectories. It is common practice for operational purposes to reduce study subjects into chronological categories when conducting research. However, there are no agreed-upon thresholds for this practice, and...
Initial COVID-19 lockdown restrictions in the United Kingdom (23rd March–12th May 2020) prompted lifestyle changes for many people. We explored the impact of this lockdown phase on pet dogs using an online survey completed by 6004 dog owners, who provided information including dog management data for the 7 days prior to survey completion (4th–12th...
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 Behav...
Introduction: The importance of using appropriate tools to measure human-animal interactions (HAI) is widely recognised. Continuing on from Wilson and Netting's (2012) review of HAI instruments up to 2008, this paper presents the results of a systematic literature review for HAI questionnaires created between 2009 and 2018, and discusses the curren...
Lifestyle changes ensued for many people across the United Kingdom (UK) in the Spring of 2020 due to ‘lockdown’ restrictions imposed to curb the spread of a newly emerged virus, SARS-CoV-2, which caused a global pandemic of the disease known as COVID-19.
More than 6,000 dog owners living in the UK completed our online survey between the 4th – 12th...
The relationship between parent and child changes around adolescence, with children believed to have: (i) an earlier puberty if they have less secure attachments to their carer; (ii) a phase of increased conflict behaviour toward their carer; and (iii) heightened conflict behaviour when carer attachments are less secure. We find support for analogo...
Exposure to chronic stressors and/or traumatic events can trigger depression-like forms of waking inactivity in non-human species (mice, horses, primates) as well as clinical depression in humans. This study aimed to test the hypothesis that elevated levels of waking inactivity in the home environment, in tandem with exposure to chronic stress and/...
Canine atopic dermatitis (cAD) is a common allergic skin condition in dogs that causes chronic pruritus. The overall quality of life in dogs with cAD is known to be reduced, and human patients with pruritic conditions report significant psychological burdens from pruritus-induced stress, and atopic dermatitis is associated with significant psychopa...
Domesticated rabbits typically exhibit shorter, flatter skulls than their wild counterparts (brachycephalism). However, brachycephaly is associated with considerable health problems, including problems with dentition. The aim of this study was to establish which type of rabbit face people prefer, with a particular emphasis on skull morphology and b...
Background:
Canine atopic dermatitis (cAD) is one the most common and distressing skin disorders seen in dogs. It is characterized by dysfunction in the skin barrier, with a complex pathogenesis combining both genetic and environmental factors.
Objectives:
To evaluate associations between environmental factors and case-control status in two clos...
There has been much concern in recent years about the welfare of elephants in zoos across North America and Europe. While some previous studies have assessed captive elephant welfare at a particular point in time, there has been little work to develop methods which could be used for regular, routine welfare assessment. Such assessment is important...
The authors would like to add the following statement to the published article [...]
Opportunities for positive social interaction are important in captive animals, and social
interactions can be used as a welfare indicator. Wild elephants live in related multigenerational herds; however, in captivity they are often managed in less related groups, which could impact the quality of their social interactions, and thus their welfare....

Epidemiology is the study of patterns of health-related states or events in populations. Statistical models developed for epidemiology could be usefully applied to behavioural states or events. The aim of this study is to present the application of epidemiological statistics to understand animal behaviour where discrete outcomes are of interest, us...
Working dog organisations, such as Guide Dogs, need to regularly assess the behaviour of the dogs they train. In this study we developed a questionnaire-style behaviour assessment completed by training supervisors of juvenile guide dogs aged 5, 8 and 12 months old (n = 1,401), and evaluated aspects of its reliability and validity. Specifically, int...

In a resource-limited world, organisations attempting to reduce the impact of health or behaviour issues need to choose carefully how to allocate resources for the highest overall impact. However, such choices may not always be obvious. Which has the biggest impact? A large change to a small number of individuals, or a small change to a large numbe...
LIMBER tail syndrome (LTS), also known as acute caudal myopathy, is an unusual and poorly understood condition affecting the muscles in the tail and is most often reported in working or sporting dog breeds (De Lahunta and Glass 2008). Although there is no clear definition for the condition, the diagnosis is based on clinical signs of a limp tail, o...
The domestic dog is one of our most popular companions and longest relationships, occupying different roles, from pet to working guide dog for the blind. As dogs age different behavioural issues occur and in some cases dogs may be relinquished or removed from their working service. Here we analyse a dataset on working guide dogs that were removed f...
The ability to measure stable and consistent behavioral traits in dogs would facilitate selection and assessment of working dogs, such as guide dogs. Ideally, these measures should predict suitability for the working role from a young age. This study assessed test-retest reliability of a juvenile guide dog behavior test and predictive validity usin...
Animal personality develops as a result of interactions between genetic components and environmental experiences. The aim of this study was to investigate the influence of rearing environment upon personality scores in potential guide dogs. Subjects were 224 potential guide dogs (104M: 120F). Volunteers living with the dogs between 3-14 months of a...
Assessment of quality of life (QoL) is an important, increasingly popular outcome measure in veterinary research and practice, particularly in dogs. In humans, QoL is commonly assessed by self-reporting and since this is not possible for animals, it is crucial that instruments designed to measure QoL are tested for reliability and validity. Using a...
Maintaining adequate welfare in captive elephants is challenging. Few studies have investigated overnight rest behavior in zoo elephants, yet time spent resting has been identified as a welfare indicator in some species. We investigated resting behavior in Asian elephants (Elephas maximus) in UK zoos, with the aim of identifying patterns or prefere...
Questions
Question (1)
I'm working with juvenile dogs, assessing their personality development over their first year of life. I've discovered behavioral changes occur around adolescence but I can't find any papers discussing the physiological changes that occur in dogs during adolescence; hormonal or neurological. I can find similar papers for rats, ground squirrels and who knows what else, but surprisingly not dogs. If you've come across anything that sounds like that then I'd really appreciate it if you could let me know.
