Zooeyia includes the potential benefits that interactions and relationships with companion animals can bring to human health. These potential benefits have been grouped into four components to describe the means through which they may occur: pets as builders of social capital, agents of harm reduction, motivators for health behavior change, and active participants in treatment plans. This construct has been used to examine the human-animal bond (HAB) and understand animal-assisted interventions. It has not, however, been intentionally applied within the context of military Veterans with posttraumatic stress disorder and comorbid substance use paired with Service Dogs (SD). A qualitative approach to analysis using zooeyia was applied to data collected during an exploratory patient-oriented, time-series research design with Veterans teamed with SDs through a national holistic Canadian training program. All four components of zooeyia were present in the experiences of Veterans with SDs; SDs were builders of social capital, agents of harm reduction, motivators for health behavior change, and active participants in treatment plans. While Veterans working with SDs reported many benefits, the pairs also experienced specific complex challenges, beyond the expected concerns for a household pet. The human-animal relationship between Veterans in this study and their SDs, and the subsequent growing bond, is a key contributing component and step to the strengthening of zooeyia. This analysis of zooeyia extends our understanding of how SDs support veterans’ health, including better management of PTSD and problematic substance use. Because the HAB is reciprocal, this analysis also challenges One Health to recognize and embrace concerns for animal welfare.
Dog ownership is related to physical activity. There could, however, be variances in the strength of this relationship between different cultures. The objective of the present study was to investigate activity behavior in dog owners (DOs) in Germany. Further, the association between dog ownership, attachment and physical activity was examined. Total physical activity, dog walking, and other dog-related activities were investigated using an online survey that was promoted in several social media groups. A German physical activity questionnaire (BSA-F) and the Lexington Attachment to Pets Scale (LAPS) were used. DOs display higher levels of total physical activity, total walking, and other physical activities than non-dog owners (nDOs). Several other dog-related activities were reported by DOs. The most prominent were retrieve work, ball games and agility. Attachment to one’s dogs was not related to total physical activity. However, attachment correlated with higher levels of time spent in dog-related physical activity and dog walking. It can be concluded that, in a German population, DOs are more physically active than nDOs. Attachment seems to correlate with type, but not quantity, of exercise in dog enthusiasts. Several dog-related activities were reported but information about them is still very limited. Therefore, future studies are needed to focus on the intensity and occurrence of these activities in a representative population of DOs in Germany.
Human-animal interaction has clear positive effects on people's affect and stress. But less is known about how animal interactions influence cognition. We draw parallels between animal interactions and exposure to natural environments, a research area that shows clear improvements in cognitive performance. The aim of this study is to investigate whether interacting with animals similarly enhances cognitive performance, specifically executive functioning. To test this, we conducted two experiments in which we had participants self-report their affect and complete a series of cognitive tasks (long-term memory, attentional control, and working memory) before and after either a brief interaction with a dog or a control activity. We found that interacting with a dog improved positive affect and decreased negative affect (in one of the two experiments), stress, and anxiety compared to the control condition. However, we did not find effects of animal interaction on long-term memory, attentional control, or working memory. Thus, we replicated existing findings providing evidence that interacting with animals can improve affect, but we did not find similar improvements in cognitive performance. These results suggest that either our interaction was not of sufficient dose or timed appropriately to elicit effects on cognition or the mechanisms underlying effects of human-animal interaction on cognition differ from effects generated by other cognition-enhancing interventions such as exposure to nature. Future research should continue to increase knowledge of the connection between nature exposure and human-animal interaction studies to build our understanding of cognition in response to animal interactions.
Animal Hoarding Disorder (AHD) is a recently acknowledged psychiatric syndrome regarded as a form of Hoarding Disorder. Despite its great complexity, AHD has been underestimated both within and outside the academic community. This systematic review of the literature will assess some features to give a description of the syndrome. We have selected 26 empirical investigations which have been analyzed for such purpose. Moreover, we have estimated the mean values of some variables such as age (55.6 years old), gender (74.9% women), households (51.8% single-person), unemployment (53.6%), number of animals per case (64.1), presence of dead animals (32.9%) and object hoarding co-morbidity (59.5%). Results will be discussed to highlight AHD particular features, the need for an integrated view around the One Welfare concept and the need for an interdisciplinary approach. Given its complexity, we recommend acknowledging AHD as a separate nosographic entity.
Animal-assisted crisis response (AACR) is an intervention that harnesses the human-animal bond for therapeutic benefit through specially trained animal-handler teams deployed to provide comfort following a mass traumatic event. During the months and years following the shooting at Marjory Stoneman Douglas High School on February 14, 2018, therapy animals joined the campus community to promote healing and stress reduction. The purpose of this quantitative study was to examine the sustained effects on bonding and stress in a sample of survivors of the tragedy who participated in animal-assisted crisis response. Data was collected through a quasi-experimental study of three intervention groups (i.e., discussion of AACR, viewing photos related to AACR, and engaging with therapy animals). Cortisol analysis indicated a reduction in stress post-intervention across groups with the largest difference in the therapy animal interaction group. Implications for AACR and addressing the psychological effects of mass traumas are provided.
Animal Assisted Intervention (AAI) is widely used in therapeutic and educational situations. It is necessary to describe the effects of AAI based on objective indices to facilitate the effective use of AAI. We investigated the effects of interacting with a dog on sympathetic and parasympathetic nervous system activities by evaluating heart rate variability (HRV) using the Lorenz plot method. Participants were thirty-four healthy volunteers (17 females and 17 males, 20-29 years of age), randomly assigned to one of three groups: the dog group, the stuffed dog group, and the plant group. Participants rated their impressions of the target (the dog, the stuffed dog, or the plant) by touching it between task blocks. The participants completed a mood scale in each block, and we measured their heart rate, respiration rate, and skin conductance response. Results indicated that interactions with the dog increased the cardiac sympathetic index of Lorentz plot, skin conductance responses, and “high-arousal and pleasant mood” score compared to the other conditions. These results suggest that short interactions with a dog activate the sympathetic nervous system, which causes an awakening effect.
Youth who identify as transgender, gender non-conforming, or non-binary (TGNC) are at increased risk for mental health challenges including anxiety, depression, and suicidality; and social challenges including bullying, isolation, and lack of familial support. Best practices in promoting the social and emotional health of TGNC youth are continually evolving, and Animal Assisted Therapy (AAT) presents a compelling yet untested approach to meeting mental health needs of this population; a group AAT intervention might help TGNC youth who feel isolated to feel more connected and supported. This exploratory study sought to identify thematic content to be included in a future AAT group intervention geared towards TGNC youth, considering both the potential role of human-animal interactions and the identified needs of this population. Three focus groups were convened; one comprised of TGNC adults (N = 8), one of mental health clinicians with advanced training related to transgender mental health (N = 4), and one of certified Animal Assisted Play Therapists® (N = 5). The content of each group was coded thematically using modified grounded theory, and several subthemes emerged under broader themes of 1) the importance of animals in providing emotional support in general and 2) desired social supports that might be beneficial for TGNC youth. These themes inform discussion of possible next steps in the development of an AAT group for TGNC youth.
Loneliness is prevalent in contemporary Western society and although it is commonly believed that pets can buffer owners against the effects of loneliness on emotional well-being, empirical research is limited. This study addressed the question of whether loneliness positively predicts the strength of the human-dog bond, and whether the human-dog bond mitigates the deleterious effects of loneliness on emotional well-being. A community sample of Australian pet-dog owners ( N =639: 123 men, 516 women) aged 18-80 participated in the study. Loneliness was conceptualised as a tri-dimensional construct comprised of social-, family-, and romantic-loneliness, while emotional well-being was operationalised in terms of positive and negative affect. Higher social-loneliness and family-loneliness predicted higher negative affect, and higher levels of all three types of loneliness predicted lower positive affect. Higher levels of family-loneliness and romantic-loneliness predicted a stronger human-dog bond, which in turn predicted higher positive affect. No relationship was evident between the human-dog bond and either social-loneliness or negative affect. The human-dog bond mediated the relationship between family-loneliness and positive affect as well as the relationship between romantic-loneliness and positive affect. These mediating effects were of the suppressor-type, indicating that the human-dog bond mitigated the deleterious effects of family-loneliness and romantic-loneliness on positive affect. These findings demonstrate the importance of conceptualising loneliness as a multi-dimensional construct in future studies regarding loneliness and human-animal relationships.
During social interactions, one must be able to interpret social signals that convey information and respond appropriately to interactants. Several factors have been shown to influence decisions of interpersonal distance preferences; however, research has yet to determine the associative effects companion animals may have on social information processing during intended interactions. Previous research ( Briones et al., 2022 ) distinguished between various breeds of dogs perceived to be higher or lower in aggression, and further showed that people had a greater tendency to interact with dogs perceived to be lower in aggression. The current studies (Study 1 n = 174; Study 2 n = 229) were an extension of that research and used computer-simulated avatar interactions to assess the influence of dog breeds and other factors on actual proxemic behavior during goal-related social interactions. Results showed that during social interactions, (a) interactants associated with dog breeds perceived higher in aggressiveness elicited larger interpersonal spaces; (b) closer interpersonal distances are maintained with friends than strangers; (c) greater affinity for dogs, in general, was related to closer proxemic distances; and (d) dog handlers taking the perspective of the approaching interactant results in greater interpersonal distances.
Canadian veterans with PTSD are increasingly accessing psychiatric service dogs as a complementary treatment for their symptoms. Due to the short life span of dogs, however, it is inevitable that these veterans will experience the loss of their PSD either through death, retirement, or relinquishment. This exploratory qualitative study shares the findings from interviews with four veterans who had experienced grief at the loss of a PSD. The themes that emerged suggest that participants experienced a grief cycle: building of a bond with their PSD, a grief response after the loss of their PSD, healing and coping, and a transitional stage when introducing a new PSD into their lives. Recommendations are made for health care professionals working with veterans with psychiatric service dogs and for service dog providers and organizations to better prepare and support their clients leading up to and after the loss of their service dog.
This study compares the effects of human-dog interactions and progressive muscle relaxation on stress in college students during the week of their final exams using self-report and physiological measures of stress. Students often cope with stress during the final exams period using various strategies such as spending time with a therapy dog. While students often report that their stress is reduced after visiting with a therapy dog, some studies find physiological evidence for a reduction in stress while others do not. During the first day of finals week, students ( N = 53) in an introductory psychology or a research methods course were randomly assigned to spend 15 minutes with a therapy dog or to spend 15 minutes doing a progressive muscle relaxation task. Heart rate variability, a physiological measure of stress, and two self-report measures of stress (the PSS-10 which is a 10 item questionnaire on the participants’ stress level and the SVAS on which the participants mark a visual scale to indicate their current stress level) were measured both before and after the treatments. Compared to the pre-treatment measures, stress was lower after the treatment. Spending time with a therapy dog can reduce stress associated with final exams. However, the intercorrelations between heart rate variability and the self-report measures were not statistically significant suggesting that the measures might correspond to different dimensions of the stress response, as explained in some theories of stress response and emotion. Future research regarding the effects of therapy dogs on stress should include at least one physiological measure of stress and ideally multiple measures. This inclusion might help clarify the underlying psychological and physiological mechanisms leading to stress reduction.
Assistance dogs fill a wide variety of disability assistance roles. In many jurisdictions, assistance dogs have the legal right to enter public places with their handlers, including those that are typically off-limits to pet animals. Unfortunately, unlawful denial of access to these places is common, which may be due to lack of understanding about these access rights. The aim of this exploratory study was to determine awareness of assistance dog public access rights among the general population of Australian adults. An online survey was completed by 328 Australian residents, only six of whom had ever lived with an assistance dog. Analyses were primarily descriptive. About half (51%) worked in an environment in which occasional encounters with an assistance dog and handler team would be possible, but most participants reported rarely or never encountering an assistance dog in their community or workplace. Nonetheless, awareness of assistance dog public access rights was generally high, with nearly all participants aware that ‘pet dog’ is not a synonym for assistance dog, and that assistance dogs have the legal right to access shopping centres and public transport. Awareness was lower for limitations on these access rights, such as gatekeepers’ (i.e., people who determine whether a person enters their premises) right to ask for evidence that the dog is an assistance dog, and the right to deny access to a dog that is not well-controlled. Women had significantly higher knowledge about this topic than men, and age was positively correlated with knowledge, but both had weak effect sizes. Future educational campaigns should aim to increase awareness of assistance dogs’ legal rights and obligations, to reduce the likelihood of unlawful access denials in the future.
While anecdotal accounts describe mental health recovery-related benefits of having Emotional Support Animals (ESAs), to date there have been no studies on such within peer-reviewed journals. This pilot study yields data on how ESAs may facilitate mental health recovery and related benefits for persons with Serious Mental Illness (SMI).Through an ESA placement program, the Hope and Recovery Pet program (HARP), shelter dogs and cats were placed as ESAs with adults (N=11) with SMI. A longitudinal mixed method research design was utilized to explore potential ESA impact. Pre- and post-placement data from participants was collected on depression, anxiety, and loneliness. Biomarker data (saliva analytes assessing oxytocin, cortisol, alpha amylase) were collected before and after ten-minute interactions with ESAs at 1, 3, 6, 9, and 12 months. Qualitative data was collected twelve months post-placement. Significant reductions in anxiety, depression, and loneliness scale scores via the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and UCLA Loneliness Scale (UCLA), respectively, were found. While not significant, there was a pattern of oxytocin increase and cortisol decrease after ten minutes of ESA interaction. Qualitative data indicated participants attributed their improvements in mental health and well-being to their respective ESAs. Findings underscore the need for continued research on ESA companionship as a mental health recovery support.
The use of animal-assisted interventions as a method of improving symptoms of autism spectrum disorder (ASD) is becoming increasingly common, with a significant proportion of available literature suggesting improvements in social communication and interaction. Less is known about potential impacts on restricted and repetitive behaviors, motor skills, or executive functions. Furthermore, it is unknown what level of interaction with an animal, if any, is needed to produce improvements. In the current study, the behavior and skills of 16 children diagnosed with ASD, aged 2 to 4 years, were observed when a therapy dog, Muffin, was actively interacting with them, passively present in a classroom, or absent from the classroom. Contrary to expectations, the children actively interacted with the dog only infrequently, and there were no differences across conditions on numerous variables. Muffin’s presence and activity level was only associated with motor skills in the children, with results indicating that the participants were more likely to remain stationary than engage in physical activity when the therapy dog was present, perhaps indicating a global calming effect. The general lack of significant differences suggests that further studies may be necessary to determine exactly which symptoms of ASD respond to animal-assisted interventions, and also to determine optimal treatment dosage and frequency. We contend that the design of animal-assisted intervention may be critical in producing previously reported benefits.
Little is known about how pet owners make end-of-life (EoL) decisions regarding their pets. We analyzed data from 1542 pet owners from North America and Europe that had made EoL decisions involving their dogs (n = 546) or cats (n=996). We measured participants’ empathy towards animals, emotion regulation, and attitudes toward pets, and asked for demographic information about themselves and the most recent pet that they had euthanized. We asked them to indicate a preference for making a decision too early versus too late, the stage of an illness or injury at which they had made their decision to euthanize, and the amount of guilt they felt for making a decision too early and too late. We hypothesized that individuals with high levels of empathy would prioritize the reduction of their pet’s suffering and would therefore make earlier decisions and feel greater guilt for having made decisions too late. This might be especially true for those with low emotion regulation as they might have more difficulty managing their own distress related to the pet’s condition. In addition, we recognized that pet owners would also consider their desire to extend the pet’s life - particularly when they had strong positive attitudes toward pets. Contrary to our predictions, those with higher reported empathy for animals were more likely to make decisions to euthanize at later stages compared to earlier stages. Cat owners made decisions later compared to dog owners. Higher levels of empathy and lower levels of emotion regulation predicted guilt for both early and late decisions. Further work is needed to explore how various owner characteristics impact EoL decisions. Our study makes a first attempt to understand this complex issue.
Animal-assisted therapy (AAT) has become increasingly popular as an adjunct to treatment across a variety of populations and disciplines. However, minimal empirical documentation for AAT exists in the literature. The purpose of this project was to assess the efficacy of animal-assisted occupational therapy (AAOT) on attention in preschoolers. We hypothesized that the presence of a specially trained canine in the treatment room would increase attention to therapist-directed activities during a table-based occupational therapy activity. A total of 12 preschool-aged children participated in this study during regularly-scheduled occupational therapy sessions. Data were collected based on the percentage of time the student was off-task during the activity. Results demonstrated statistical significance, with the children significantly less off-task on average when a dog was present during instruction than when a dog was not present (t (11) = 2.89, p = .015). This study provides additional research to support the efficacy of AAT with a focus on the preschool population, which is an area that is underrepresented in published literature.
This study was designed to better understand how service dog partners experience the loss of their service dog. An anonymous survey was distributed to service dog partners who had lost a dog within the last five years. One-way ANOVAs were used to assess loss differences (retirement vs. death) on scores for Centrality of Events Scale, Warwick-Edinburgh Mental Well-Being Scale, Social Constraints Measure, and Self-Compassion Scale. Linear regression was conducted on the total bereavement score to determine the impact of the above assessment measures. We found higher grief scores for those whose service dog died compared to those whose dog retired. Perceptions of social constraints and feelings related to the centrality of the event were predictors of overall grief for those who lost a dog due to retirement; centrality of event feelings predicted grief level for those experiencing a death. Findings suggest a need for grief support for service dog partners.
This study examined possible connections between pet ownership and children’s health status, as mediated by children’s anxiety and physical activity. A total of 134 mothers with a preschool age child participated in the study. Mothers completed a demographic survey, responded to questions about owning a pet, and reported on their child’s anxiety, physical activity, and physical health status. Mean comparisons revealed that children from households with a pet had lower scores on mother reported anxiety, higher scores on mother reported physical health and psychosocial health, and lower scores on mother reported vulnerability to illness, compared to children from households without a pet. Regression analyses revealed that associations between pet ownership and mother’s reports of children’s physical health and lower vulnerability to illness, but not psychosocial health, remained significant even after accounting for mother education and family income. In addition, the association between pet ownership and child physical health and vulnerability to illness was partially mediated by mother reported child anxiety. The present study supports previous evidence to suggest that pet ownership is associated with better health outcomes for children, and that this link may be accounted for by child anxiety.
