Development of the dog executive function scale (DEFS) for adult dogs.

Executive functions (EFs) are cognitive processes that are used to effortfully self-regulate behaviour and might be important for dogs' success in working and pet roles. Currently, studies are assessing dogs' EF skills through often laborious cognitive measures, leading to small sample sizes and lacking measures of reliability. A complementary method is needed. The aim of this study was to develop a dog executive function scale (DEFS) for adult dogs. Focus groups were held with people working with dogs professionally to refine a pool of items describing dog behaviours related to EF. A survey was distributed online to a convenience sample of N = 714 owners of adult dogs. Exploratory and confirmatory factor analysis identified six distinguishable factors named behavioural flexibility, motor inhibition, attention towards owner, instruction following, delay inhibition and working memory. These factors appear similar to factors identified in human EF scales. Working dogs exhibit higher EF scores on the DEFS than non-working dogs. Dogs sourced from breeders exhibited higher DEFS scores than dogs sourced from shelters, and the amount of training received positively correlated with dogs' DEFS scores. The DEFS requires further validation with cognitive measures. The DEFS could then be used by researchers to complement assessment of dogs' EF skills through cognitive measures or assess dogs' EF skills in large samples.

Executive functions and household chores: Does engagement in chores predict children's cognition?

INTRODUCTION: The benefits of completing household chores appear to transfer beyond managing day-to-day living. It is possible that chore engagement may improve executive functions, as engagement in chores require individuals to plan, self-regulate, switch between tasks, and remember instructions. To date, little research has been conducted on household chores and executive functions in children, for whom these skills are still developing. METHODS: Parents and guardians (N = 207) of children aged 5-13 years (M = 9.38, SD = 2.15) were asked to complete parent-report questionnaires on their child's engagement in household chores and their child's executive functioning. RESULTS: Results of the regression model indicated that engagement in self-care chores (e.g., making self a meal) and family-care chores (e.g., making someone else a meal) significantly predicted working memory and inhibition, after controlling for the influence of age, gender, and presence or absence of a disability. For families with a pet, there was no significant relationship between engagement in pet-care chores and executive function skills. CONCLUSION: We strongly recommend that further research explore the relationship between chores and executive functions. It is possible that parents may be able to facilitate their child's executive function development through encouraging participation in chores, whereas chore-based interventions (e.g., cooking programmes) may also be used to target deficits in ability.

Environmental influences on development of executive functions in dogs.

Executive functions (EFs) are a set of cognitive processes used for effortful self-regulation of behaviour. They include inhibition, working memory, cognitive flexibility and, in some models, attention. In humans, socioeconomic factors and life experiences shape development of EFs. Domestic dogs (Canis familiaris) must often regulate their behaviour in the human environment (e.g. no jumping up on humans or chasing cats), and life experiences also probably influence the development of EFs in dogs. Research into dog cognition and behaviour has been thriving, and some methods used to explore these concepts (e.g. object-choice task, questionnaires measuring traits like distraction and aggression) are likely to be sensitive to differences in EFs, even if that is not their stated aim. Here we examine relevant studies to identify experiential factors which may influence the development of EFs in dogs living in human care. These are early experience, training, housing and stress. We conclude that the development of dogs' EFs may be negatively affected by hardships, and positively by surmountable challenges, early in life. Training methods appear important, with punishment-based methods leading to poorer dog EFs. Kennel environments seem to affect dog EFs negatively. While mild stressors might enhance the development of EFs, too much stress seems to have negative effects. Regulation of behaviour, a key outcome of EFs, is crucial for dogs' integration into human society. We should, therefore, strive to better understand how the environment shapes dogs' EFs.

When zoo visitors "connect" with a zoo animal, what does that mean?

Connection with a zoo animal may increase conservation-mindedness in zoo visitors, potentially resulting in conservation-oriented behavior change. No research has attempted to establish what this "connection" actually means. Visitors (N = 85) to Melbourne Zoo were asked to name the animal with which they most connected, the extent to which they connected with it, and to qualitatively describe what it meant to connect with that animal. Many (but not all) participants connected with charismatic megafauna: primate, great ape, large carnivore, or large herbivore. Qualitative analysis revealed five common themes in the meaning of connection: Appreciation, Attribution, Inspires Emotions, Interaction, and Proximity. Overall connection level was significantly correlated with perceptions of conservation caring for the chosen species. Future research should aim to determine what factors affect a zoo visitor's connection level, which could impact attitudes and behaviors toward conservation.

Visual perception in domestic dogs: susceptibility to the Ebbinghaus-Titchener and Delboeuf illusions.

Susceptibility to geometrical visual illusions has been tested in a number of non-human animal species, providing important information about how these species perceive their environment. Considering their active role in human lives, visual illusion susceptibility was tested in domestic dogs (Canis familiaris). Using a two-choice simultaneous discrimination paradigm, eight dogs were trained to indicate which of two presented circles appeared largest. These circles were then embedded in three different illusory displays; a classical display of the Ebbinghaus-Titchener illusion; an illusory contour version of the Ebbinghaus-Titchener illusion; and the classical display of the Delboeuf illusion. Significant results were observed in both the classical and illusory contour versions of the Ebbinghaus-Titchener illusion, but not the Delboeuf illusion. However, this susceptibility was reversed from what is typically seen in humans and most mammals. Dogs consistently indicated that the target circle typically appearing larger in humans appeared smaller to them, and that the target circle typically appearing smaller in humans, appeared larger to them. We speculate that these results are best explained by assimilation theory rather than other visual cognitive theories explaining susceptibility to this illusion in humans. In this context, we argue that our findings appear to reflect higher-order conceptual processing in dogs that cannot be explained by accounts restricted to low-level mechanisms of early visual processing.

Exploring the Benefits of Dog-Assisted Therapy for the Treatment of Complex Trauma in Children: A Systematic Review.

BACKGROUND: The manifestation of complex trauma results from exposure to severe and repetitive stressors occurring within the caregiver system. Frequently associated with child maltreatment, complex trauma can lead to impairments in multiple domains, including attachment, affect and behavioural regulation, and cognition. Treatments, including Trauma-Focused Cognitive Behavioural Therapy, have been shown to be efficacious, but high attrition rates point to the need for complementary methods that boost client retention and treatment efficacy. This systematic review examines whether dog-assisted therapy has beneficial impacts on the treatment of complex trauma and whether it can decrease treatment attrition among children presenting with complex trauma exposure. METHODS: We followed PRISMA guidelines to locate relevant research reports. Seven published research reports matched the inclusion criteria. RESULTS: Dog-assisted therapy may increase the efficacy of standard interventions for complex trauma, although only one study formally assessed treatment retention. Across most studies, there is an overall lack of detailed information on the nature of therapeutic activities involving the dog and how these activities may complement or enhance therapy as usual. Studies were of varying methodological quality, impacting the reliability of findings. CONCLUSIONS: Future studies should aim to better describe and justify dog-assisted therapy techniques and evaluate these in comparison with standard evidence-based approaches to the treatment of childhood complex trauma.

Impact of Interactions with a Puppy and Handler Versus a Handler Alone on Stress and Vitality in a University Setting: A Crossover Study.

Brief interactions with a well-behaved dog can enhance wellbeing, but most campus-based dog visitation programs employ adult, trained dogs. There is little research about the impact of puppies on wellbeing or stress in this context. The aim of this study was to examine changes in perceived stress and vitality after interacting with a puppy. Staff and students (N = 32) at an Australian university attended the campus on two occasions, one week apart, as part of a crossover design. Participants were pseudo-randomly allocated to a group whereby they spent 20 min interacting with a handler alone at Visit 1 and interacted with a puppy and handler at Visit 2, or another group which reversed the interaction order. Perceived stress and subjective vitality were measured before and after each interaction. The increase in vitality was greater in the group experiencing the puppy and handler interaction first (significant main effect, F(1,49) = 646.89, p = 0.024, η2p = 1.00), regardless of the visit, possibly due to a social lubricating effect by the puppy, which carried over to the 'handler alone' second visit. Reductions in perceived stress were greater after the interaction with the puppy, for both groups (significant interaction effect, F(1,49) = 5.13, p = 0.029, η2p = 0.11), indicating that the puppy's presence can reduce stress more than the handler alone. This extends the evidence for university-based dog-facilitated wellbeing programs, by showing that interactions with puppies can also be effective. This is important as it may mean that puppies already on campus as part of a socialization/training program can be incorporated into wellbeing programs for staff and students.

Association of Socioeconomic Status and Reasons for Companion Animal Relinquishment.

It is important to understand the reasons for companion animal relinquishment to help reduce the financial and ethical problems arising from too many dogs and cats in shelters. This study investigates the socioeconomic factors and reasons behind companion animal relinquishment in Australia, utilizing data from five animal shelters, over a five-year period (Financial Year 2018/19 to 2022/23). Descriptive statistics reveal that the median Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD) decile of companion animal guardians who relinquished their companion animal was decile 4 out of 10, indicating that they live in areas of lower-than-average socioeconomic status. Cats accounted for 59.4% and dogs for 40.6% of all relinquishments, with more relinquishments from lower socioeconomic deciles (1-5) (cats: 62.6%, dogs: 65.8%). The median age of relinquished cats was 5 months and dogs 16 months, with human factor-related issues (e.g., Housing, Financial Constraints, Human Healthcare) cited in 86% of cases. Descriptive analysis for the five financial years shows a declining trend in numbers of relinquishments, with housing issues (31.2%) identified as the primary reason, followed by ownership decisions (16.2%), financial constraints (11.2%), and human health issues (10.4%). Comparing the reasons for relinquishment between lower (decile 1-5) and higher (decile 6-10) socioeconomic status demonstrated that financial difficulties were a more common reason in lower vs. higher socioeconomic groups, while human health and family-related issues are more common in higher vs. lower socioeconomic groups. These findings highlight the critical role of socioeconomic factors in understanding why people relinquish their companion animals, which can inform targeted interventions to support companion animal welfare across different socioeconomic backgrounds.

An Investigation of Meat Eating in Samples from Australia and Germany: The Role of Justifications, Perceptions, and Empathy.

Despite concerns about animal welfare, and health and environmental issues associated with eating meat, meat consumption has continued to increase worldwide, including in Australia. One exception to this is Germany, with 2021 meat consumption levels being the lowest in the last 30 years. This pre-registered study investigated socio-cultural variables associated with meat consumption in Germany (n = 399) and Australia (n = 399) in a cross-sectional online survey. Participants reported levels of current and intended meat consumption, and they completed measures of speciesism, motivations to eat meat, empathy, animal farming perceptions, perceived behavioural control (PBC) over meat eating, and avoidance and dissociation regarding the animal origins of meat. In both Australia and Germany, enjoying the taste of meat positively predicted consumption and empathy towards farmed animals negatively predicted consumption. PBC was a strong positive predictor of intentions to reduce meat consumption in both countries. Empathy and liking the taste of meat were among the best predictors of red meat and poultry consumption, suggesting that interventions to reduce meat consumption may work best by targeting these factors while also increasing people's sense of control over their food choices.

Executive Functions as Measured by the Dog Executive Function Scale (DEFS) over the Lifespan of Dogs.

Executive Functions (EFs) are needed for effortful self-regulation of behaviour and are known to change over the lifespan in humans. In domestic dogs, EFs can be assessed through behavioural rating scales, such as the Dog Executive Function Scale (DEFS). The primary aim of this study was to investigate whether the DEFS, developed initially using a sample of adult dogs, can be used in juvenile (<1 year) and senior (>8 years) dogs. Confirmatory factor analysis of a juvenile and senior dog sample led to good model fit indices, indicating that juvenile and senior dogs' EF structure follows the same functional organisation as found in the DEFS. The secondary aim was to analyse the lifespan development of EFs. Analysis of subscale scores revealed multifaceted relationships with age for four subscales. Working Memory and Attention Towards Owner showed the u-shaped curve traditionally associated with the lifespan development of EFs. Forms of inhibition showed complex associations with age, i.e., Delay Inhibition declined in aging and Motor Regulation increased during aging. Training history and Working Status influenced performance independent of age. More highly trained dogs and working dogs exhibited higher EF skills. Training history appeared more important for EF in non-working dogs than working dogs, perhaps because all working dogs receive a high level of training.

Can Interacting with Animals Improve Executive Functions? A Systematic Review.

There has been growing interest in the potential benefits of using human-animal interactions to improve executive functions: cognitive processes that allow individuals to plan, solve problems, and self-regulate behaviour. To date, no comprehensive review has been conducted. The purpose of this study was to evaluate existing literature, adopting broad inclusion criteria. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 16 papers were identified from peer-reviewed literature. Additional papers were identified from grey literature, including 6 dissertations and 1 thesis. A review of these 23 studies found that human-animal interactions and executive functions are investigated in three main ways: (1) exploring the potential benefits of the human-pet relationship, (2) exploring the impact of an animal's presence during administration of executive function tests, and (3) evaluating the efficacy of animal-assisted services (e.g., animal-assisted therapy) on executive functions. Five of the included studies reported a significant improvement across all measured domains of executive functions, but effect sizes were underreported. Comparatively, 9 studies reported mixed findings, d = 0.32-0.55, while 8 studies reported no significant results. The overall rigour of the research was limited, with great heterogeneity between the study methodologies and outcome measures used. It is recommended that future studies utilise high-quality research methodologies through the use of randomisation, pre- and postmeasures, and appropriate control conditions, where possible.

Exploring the Experiences of Volunteer Assistance Dog Puppy Raisers from the Same Program at Two Australian University Campuses.

Assistance dogs are beneficial; however, accessing one can be challenging due to the time, cost, and high failure rates associated with training. A major factor contributing to a high failure rate appears to be the competency of volunteer puppy raisers (PRs), with returning PRs typically more effective than first-time PRs. However, there remains a gap in the literature dedicated to examining PRs' experiences and how they are affected by the raising programs. This study analysed two groups of PRs (N = 16) from the same university-based program in different Australian regions (i.e., one regional and one suburban). Semi-structured interviews were conducted and analysed both inductively and deductively. The inductive approach identified four major themes that helped to understand the PRs experiences throughout the program: expectations as a PR, organisational and environmental support and suitability, the intensity of PR workload, and practical support. The deductive analysis identified four functions of volunteerism relevant to PRs' motivations: altruism (values), egoism (enhancement), interacting with others (social), and learning new skills (understanding). Overall, the results obtained from the two groups were consistent with past findings suggesting the benefits of organisational and practical support. These findings further develop our understanding of how to enhance puppy-raising experiences.

Application of an Adapted Behaviour Change Wheel to Assistance Dog Puppy Raising: A Proposed Raiser-Centred Support Program.

Puppy raising (PR) programs recruit volunteer community members (raisers) to raise assistance dog (AD) candidates from puppyhood until the dogs are ready for advanced training. Once qualified, ADs assist human handlers with a disability to live more independently. Unfortunately, about 50% of all puppies do not meet the behavioural standards required for further training after completing a PR program. This increases costs and lengthens the time taken for a handler to obtain an AD. Research has identified several factors that influence raisers' experiences. It has also shown that raisers' socialisation and training practices affect perceived puppy behaviour. Drawing on the argument that puppy raiser practices are central to improving overall puppy raising program outcomes, this paper interprets recent findings within the framework provided by the behaviour change wheel-an established behaviour change framework-to suggest a coordinated approach to supporting puppy raisers. The recommendations will allow future research to employ more objective measures and more rigorous experimental designs as the field attempts to corroborate existing findings and develop evidence-based models of practice.

Family Bonds with Pets and Mental Health during COVID-19 in Australia: A Complex Picture.

The COVID-19 pandemic has drawn attention to the health-promoting features of human-animal relationships, particularly for families with children. Despite this, the World Health Organization's (1986) Ottawa Charter remains human-centric. Given the reciprocal health impacts of human-animal relationships, this paper aims to (i) describe perceived pet-related benefits, worries, and family activities; and to (ii) examine differences in perceived benefits, worries, and activities for parents and children with and without clinical mental health symptoms. We recruited 1034 Australian parents with a child < 18 years and a cat or dog via a national online survey between July and October 2020. Most parents reported their pet was helpful for their own (78%) and their child's mental health (80%). Adjusted logistic regression revealed parents with clinical psychological distress were 2.5 times more likely to be worried about their pet's care, well-being, and behaviour (OR = 2.56, p < 0.001). Clinically anxious children were almost twice as likely to live in a family who engages frequently in pet-related activities (e.g., cooked treats, taught tricks, OR = 1.82, p < 0.01). Mental health and perceived benefits of having a pet were not strongly associated. Data support re-framing the Ottawa Charter to encompass human-animal relationships, which is an often-neglected aspect of a socioecological approach to health.

Mobile Zoos and Other Itinerant Animal Handling Events: Current Status and Recommendations for Future Policies.

Mobile zoos are events in which non-domesticated (exotic) and domesticated species are transported to venues such as schools, hospitals, parties, and community centres, for the purposes of education, entertainment, or social and therapeutic assistance. We conducted literature searches and surveyed related government agencies regarding existing provisions within laws and policies, number of mobile zoos, and formal guidance issued concerning operation of such events in 74 countries or regions. We also examined governmental and non-governmental guidance standards for mobile zoos, as well as websites for mobile zoo operations, assessed promotional or educational materials for scientific accuracy, and recorded the diversity of species in use. We used the EMODE (Easy, Moderate, Difficult, or Extreme) algorithm, to evaluate identified species associated with mobile zoos for their suitability for keeping. We recorded 14 areas of concern regarding animal biology and public health and safety, and 8 areas of false and misleading content in promotional or educational materials. We identified at least 341 species used for mobile zoos. Mobile zoos are largely unregulated, unmonitored, and uncontrolled, and appear to be increasing. Issues regarding poor animal welfare, public health and safety, and education raise several serious concerns. Using the precautionary principle when empirical evidence was not available, we advise that exotic species should not be used for mobile zoos and similar itinerant events.

The Impact of the Social Determinants of Human Health on Companion Animal Welfare.

The social determinants of health (SDH) focus on the social, physical and economic factors that impact human health. Studies have revealed that animal guardians face a range of challenges in attaining positive welfare outcomes for their companion animals, which can be influenced by socioeconomic and environmental factors. Despite this, there is a lack of research specifically exploring the relationship between SDH and animal welfare outcomes. Given that the SDH impact on humans, which in turn directly impacts on their companion animal, it is important to adapt an SDH framework for companion animal welfare by characterising the impact of the SDH on companion animal guardians in their attempts to care for their animals and, by extension, the associated welfare outcomes. This paper explores how these human health determinants may impact animal welfare and the possible challenges that may arise for the guardian when attempting to meet their companion animal's welfare needs. By integrating the SDH with other key frameworks, including the five domains model of animal welfare, through multidisciplinary collaboration, this framework can be used to inform future programs aiming to improve animal welfare.

The Effect of Dog Presence on the Therapeutic Alliance: A Systematic Review.

The development of a therapeutic alliance represents one of the most important processes that occurs in psychological therapy and is one of the strongest predictors of treatment outcome. To ensure the effective delivery of psychological interventions, it is important to explore factors which may improve the therapeutic alliance. There are well-documented effects of human-animal interactions in social settings, and researchers have also considered the effect of dog presence on the therapeutic alliance. A systematic review was conducted in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist. Database searches included CINAHL, Cochrane, Embase, MEDLINE, PsycINFO, and Scopus. The inclusion criteria were studies that assessed the effect of dog presence on the therapeutic alliance and provided a quantitative outcome measure. Six studies met the inclusion criteria and were included in the systematic review. Three of the included studies observed no significant effect of dog presence on the therapeutic alliance; three studies did observe a positive effect, with effect sizes ranging from d = 0.10 to d = 0.58. All six studies took place in either research or clinical settings. Studies differed in terms of help-seeking versus non-help-seeking populations, where help-seeking populations were genuinely pursuing a psychological intervention. Heterogeneity was observed regarding study procedure and outcome measures used. Current data is limited, and initial evidence suggests that the effect of dog presence on the therapeutic alliance remains unclear, illustrated by inconsistent outcomes across the included studies. Further research is warranted before introducing dogs into therapeutic settings for this purpose.

Pet management practices of frog and turtle owners in Victoria, Australia.

BACKGROUND: Available empirical evidence suggests that pet animals do not always experience an optimal welfare state. However, most pet welfare research has focused on dogs and cats, with less research investigating amphibians and reptiles. The aim of this study was to characterise how owners of pet frogs and turtles in Victoria, Australia, attempted to meet their pets' welfare needs. METHODS: Pet frog owners (n = 128) and turtle owners (n = 60) completed an online survey, comprising questions about how they managed their pets' environmental, behavioural, social, nutritional and physical health needs. RESULTS: For both frogs and turtles, positive and negative welfare indicators were found. Owners described pet enclosures as waterproof and escape-proof. However, fewer than 20% of owners of either pet type had an enclosure size that met the minimum standards described in the relevant Code of Practice. LIMITATIONS: Because this study relied on self-reporting, future research should directly observe animals under household care to provide a more objective measure of welfare. CONCLUSION: Pet frogs and turtles in Victoria, Australia, may not always be experiencing an optimal welfare state, despite their owners' stated desire to care for them as well as possible.

Parent and child mental health during COVID-19 in Australia: The role of pet attachment.

Restrictions, social isolation, and uncertainty related to the global COVID-19 pandemic have disrupted the ways that parents and children maintain family routines, health, and wellbeing. Companion animals (pets) can be a critical source of comfort during traumatic experiences, although changes to family routines, such as those caused by COVID-19, can also bring about challenges like managing undesirable pet behaviours or pet-human interactions. We aimed to examine the relationship between pet attachment and mental health for both parents and their children during the COVID-19 pandemic in Australia. A total of 1,034 parents living with a child under 18 years and a cat or dog completed an online cross-sectional survey between July and October 2020. Path analysis using multivariate linear regression was conducted to examine associations between objective COVID-19 impacts, subjective worry about COVID-19, human-pet attachment, and mental health. After adjusting for core demographic factors, stronger pet-child attachment was associated with greater child anxiety (parent-reported, p < .001). Parent-pet attachment was not associated with self-reported psychological distress (p = .42), however, parents who reported a strong emotional closeness with their pet reported greater psychological distress (p = .002). Findings highlight the role of pets during times of change and uncertainty. It is possible that families are turning to animals as a source of comfort, during a time when traditional social supports are less accessible. Alternatively, strong pet attachment is likely to reflect high levels of empathy, which might increase vulnerability to psychological distress. Longitudinal evidence is required to delineate the mechanisms underpinning pet attachment and mental health.

The Cat-Owner Relationship: Validation of the Italian C/DORS for Cat Owners and Correlation with the LAPS.

Globally, most people now own a pet. Scales have been developed to understand the impact of pet ownership on people's lives and to measure specific aspects of the owner-pet relationship. The Cat-/Dog-Owner Relationship Scale (C/DORS) is a tool developed to investigate this relationship in both dog and cat owners. The aim of the study was to refine and validate the C/DORS for cat owners in Italian. Exploratory Factor Analysis and Confirmatory Factor Analysis (CFA) were used to determine the most appropriate factor model. Construct validity was confirmed by correlating the C/DORS subscales with the Lexington Attachment to Pets (LAPS) subscales. Results confirmed the original structure of the English version (i.e., three factors: Pet Owner Interaction = POI, Perceived Emotional Closeness = PEC, Perceived Costs = PC) and CFA confirmed the structure of LAPS and C/DORS scales. Cronbach's alpha demonstrated the Italian version of the two scales to have good internal reliability for all domains. Owners of cats living exclusively indoors reported higher scores on POI and PEC compared to indoor/outdoor cats. Owning both cats and dogs was correlated with lower scores on POI, and fewer perceived costs (i.e., PC) of cat ownership. Finally, behaviour problems, not being neutered, and lack of previous experience with cat ownership were associated with lower scores on PC.
