The nomenclature used to describe animals working in roles supporting people can be confusing. The same term may be used to describe different roles, or two terms may mean the same thing. This confusion is evident among researchers, practitioners, and end users. Because certain animal roles are provided with legal protections and/or government-funding support in some jurisdictions, it is necessary to clearly define the existing terms to avoid confusion. The aim of this paper is to provide operationalized definitions for nine terms, which would be useful in many world regions: “assistance animal”, “companion animal”, “educational/school support animal”, “emotional support animal”, “facility animal”, “service animal”, “skilled companion animal”, “therapy animal”, and “visiting/visitation animal”. At the International Society for Anthrozoology (ISAZ) conferences in 2018 and 2020, over 100 delegates participated in workshops to define these terms, many of whom co-authored this paper. Through an iterative process, we have defined the nine terms and explained how they differ from each other. We recommend phasing out two terms (i.e., “skilled companion animal” and “service animal”) due to overlap with other terms that could potentially exacerbate confusion. The implications for several regions of the world are discussed.

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.

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 considerably for many pet dogs, leading to concerns about the development of SRBs when dogs are left alone more again. The main aim of this study was to test the hypothesis that dogs whose time left alone decreased most (compared to a February 2020 pre-COVID baseline) would be at greatest risk of developing new signs of SRB when time left alone increased again. To achieve this aim, we utilised survey data gathered from dog owners between 4th May and 3rd July 2020, during the first COVID-19 ‘lockdown’ period in the United Kingdom (UK), and a follow-up survey of the same dog-owner cohort, completed when restrictions had eased between 10th October and 2nd November 2020. Individual dogs fluctuated considerably in whether they showed signs of SRB or not across the study period (n = 1807). Overall, the prevalence of SRB in the population decreased from 22.1% to 17.2%, as did the time dogs were left alone for between February and October 2020. However, 9.9% of dogs had developed new signs of SRB by the follow-up survey in October 2020, with dogs whose leaving hours decreased most during lockdown restrictions being at increased risk of developing SRBs. These findings have implications for our understanding of the etiology of SRB, by showing a link between changes in owner routine and SRB risk.

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 went in measuring HDB (defined as the unique, dynamic and reciprocated relationship between a person and dog, one in which each member can influence the other’s psychological and physiological state). A systematic literature review revealed that a common limitation in HDB questionnaires was a lack of questions based on the dog’s investment in the bond and, therefore, a failure to measure the two-way characteristic of the HDB. This led to the second part of the study: to identify novel themes relating to dog investment in the HDB from which new tool questions could be developed. This was investigated qualitatively using twelve semi-structured interviews on HDB, undertaken with participants from a variety of dog–guardian relationship types. HDB themes that emerged included ‘adaptation’, ‘understanding of a dog’s preferences, likes, and dislikes’, and ‘affirmation’. Subthemes included ‘boundaries’ and ‘expectations’ (within adaptation), ‘excitement’, ‘proximity’, ‘affection’, and ‘recall’ (within affirmation). The themes that arose provide a foundation from which to build new lines of questioning within HDB tools. Such questioning can better represent a dog’s investment in the HDB and, therefore, help create tools that reflect the reciprocal nature of a bond more accurately.

The multidisciplinary nature of human-(nonhuman) animal interactions (HAI), and global interest in HAI development, has led to an explosion of research in recent years justifying the need to update previous reviews in the subject area. This paper reports the results of a systematic literature review focusing on measures of HAI created in the ten-year period since previous reviews ended (2008). Thirty new HAI questionnaires were identified using two sets of search terms. Results indicated that reliability and validity testing were still not standard within tool creation. Companion animal HAI remained dominant in the instrument field; however, there was continued research into exotic animal HAI and the initiation of research into therapy and assistance animal HAI. Refinement of terminology and consistent use of definitions could facilitate researchers from various disciplines being able to locate relevant research in future. Similar review updates are recommended for attitudes to animal tools.

Dog behaviour that owners perceive as undesirable can compromise dog welfare, impact the owner and human–animal bond, and may result in relinquishment or euthanasia. This longitudinal study explored the type and percentage of owner-perceived undesirable behaviours in 6, 9, 12, 15 and 18-month-old dogs, and examined differences in the prevalence of four commonly reported behaviours across these timepoints. Owners reported their dog’s undesirable behaviours via free-text answers in self-administered surveys. Of the five timepoints studied, the highest percentage of dogs reported by their owners to display one or more undesirable behaviours was in the 12-month survey (42.1%, 513/1219). Barking, jumping up, pulling on the lead and recall issues were the most commonly reported behaviours across all timepoints. Binomial mixed-effects models revealed a significant difference in prevalence of barking, pulling on the lead and recall issues between the timepoints, but no significant difference in the occurrence of jumping up at people. With many dogs in this study being reported to display undesirable behaviour, it is crucial that stakeholders inform dog owners, especially first-time owners, about the behaviours they may experience from young dogs and where to seek appropriate training/behaviour advice to potentially reduce the risk of relinquishment related to behaviour.
