New Research to Examine Changes to Heart and Brain Following Interactions with Therapy Dogs

The Human Animal Bond Research Institute Awards Grant to University of Wollongong

Washington, D.C. (March 3, 2025) — The Human Animal Bond Research Institute (HABRI) today announced a new grant for research to examine the effects of therapy dog interactions on heart and brain activity. This grant was awarded to a team of researchers at the University of Wollongong, led by Jillian Teo, PhD Candidate in Clinical Psychology at the University of Wollongong along with Professor Stuart Johnstone at the School of Psychology and Professor Susan Thomas at the Graduate School of Medicine.

This study will investigate the changes in heart and brain activity occurring in university students during interactions with therapy dogs and aims to better understand the mechanisms behind the benefits of human-dog interactions on human health and wellbeing. In addition to measurements of heart and brain activity, researchers will also collect self-report measures of emotional states and psychological distress from students. The study hypothesizes that therapy dog interactions will lead to greater relaxation compared to standard relaxation methods which could potentially inform future interventions and policies to optimize student health.

“Our preliminary study indicates that therapy dogs can favorably influence multiple human health-related pathways, including the autonomic and central nervous systems, likely through reductions in stress and increases in relaxation,” said Jillian Teo, the Principal Investigator for this project. “This new study will yield insights into the mechanisms underlying these benefits for human health and facilitate the development of evidence-based practices to optimize future animal-assisted interventions for improved health and wellbeing.”

This study will adopt a repeated measures design to examine psychophysiological outcomes from 100 university students, combining subjective self-report measures with objective physiological measurements including heart rate, heart rate variability, and an electroencephalogram (EEG). The study will further add to the existing literature by providing a more complete understanding of the psychophysiological changes in humans and related health benefits resulting from human-dog interactions.

“Therapy dogs offer an accessible public health strategy for college and university students, and for many populations experiencing stress and other challenges to their mental health,” said Steve Feldman, HABRI President. “HABRI is proud to support this study, which will use rigorous science to guide health interventions for students and all who could benefit from interactions with therapy dogs.”

New Research to Study Impact of Therapy Dogs on Easing Child Anxiety in the Emergency Room

 The Human Animal Bond Research Institute (HABRI) and Pet Partners announced today a grant to Indiana University School of Medicine for a new research project, Canine-assisted anxiety reduction in pediatric emergency care (CANINE III). The study will investigate the impact of therapy dog visits on the anxiety levels of children in emergency care.   “Registered Pet Partners therapy dog teams visit hospitals throughout the country, and we know they can put a smile on a child’s face, no matter what they are going through,” said C. Annie Peters, President and CEO of Pet Partners. “Scientific research to validate the efficacy of therapy dogs in the emergency room has the potential to not only provide more children with much needed comfort and emotional support, but to also help serve as a complementary intervention to improve medical outcomes.”  “Virtually all children experience some degree of psychological stress as patients in the emergency department,” says the Principal Investigator, Jeffrey Kline, MD, IU School of Medicine “The inclusion of therapy dog visits in addition to a child-life specialist could provide a low cost, low risk method to help reduce child and parental anxiety in the emergency department.”   CANINE III is a NCT-registered, two-arm, block randomized trial with one to one matching of patients receiving therapy dogs as an adjunct with a child life specialist, compared with children who receive child life specialists alone. The children will receive a 15-minute visit, with the research team periodically collecting saliva samples to test for cortisol levels, or the level of stress. Dr. Kline will complete this project alongside co-investigator Alan Beck, PhD, Purdue University. The study will also test if therapy dogs afford greater anxiety reduction in children with psychiatric complaints, autism spectrum disorder, or brain injury, versus children with none of those conditions.   All...

Survey Shows Health Benefits of Pets Linked to Improved Veterinary Care

The Human Animal Bond Research Initiative (HABRI) Foundation and the American Animal Hospital Association (AAHA) today announced the findings of a new survey on how knowledge of the scientific benefits of the human-animal bond impacts the way pet owners care for their companion animals. The survey asked pet owners about their awareness of research that shows pets improve human health and found that this knowledge motivated them to take better care of their pets, including a significant, positive impact on veterinary care. “When educated about the scientific research on the human-animal bond, pet owners are more likely to take important measures to improve pet health and augment their relationship with their veterinarians,” said AAHA Chief Executive Officer, Michael Cavanaugh, DVM, DABVP (C/F). “AAHA-accredited animal hospitals continue to raise the standard for veterinary care across the country, and HABRI gives us another way to connect with pet owners to enhance that care.” When 2,000 pet owners were educated about the human health benefits of pet ownership: 92% said they were more likely to maintain a pet’s health, including keeping up with vaccines and preventive medicine 89% said they were more likely to maintain a pet’s health, including regular check-ups with a veterinarian 88% said they were more likely to provide a pet with higher quality nutrition 51% said they were more likely to purchase pet health insurance 62% said they were less likely to skip visits to the veterinarian 89% said they were more likely to take better care of a pet “When people find out that pets improve heart health, decrease stress, help alleviate depression and address specific conditions that include autism, PTSD and Alzheimer’s, they become more focused on caring for their pet’s health,” said HABRI Executive Director, Steven Feldman. “More awareness of human-animal bond science improves veterinary care and leads to a healthier pet population.” Veterinarians,...

New Research Looks at Impact of Service Dogs on Medication Regimens for Veterans with PTSD

The Human Animal Bond Research Institute (HABRI) announced today the online publication of a study titled, “The Effect of a PTSD Service Dog on Military Veterans’ Medication Regimens: A Cross-Sectional Pilot Study”, in the journal Anthrozoos. Findings of the study, conducted by researchers at the Purdue University College of Veterinary Medicine and the Purdue University College of Pharmacy, found no significant differences between post-9/11 U.S. veterans living with post-traumatic stress disorder (PTSD) who were provided with a psychiatric service dog and veterans on a waitlist to receive a service dog in terms of number and type of medications reported. However, veterans with a service dog were more likely to report that their doctor had decreased dosage or removed medications, as compared to veterans on the waitlist to acquire a service dog. “Our previous research has found that PTSD service dogs can improve specific areas of functioning and symptomology for military veterans. This new research builds on these findings by exploring how PTSD service dogs impact veterans’ medication use,” said study co-author Dr. Kerri Rodriguez, Postdoctoral Researcher at Colorado State University. “These results indicate that PTSD service dogs played a positive supporting role. Veterans kept up with their medication regimens, indicating that the presence of the service dog was not associated with any lapse in standard treatment. While having a PTSD service dog may not completely alleviate veterans’ needs for sleep, pain, or anxiety medications, there were reported decreases in dosage levels, shedding additional light on the potential value of these service dogs as a complimentary intervention.” The objective of this study was to quantify the effect of PTSD service dogs on medication use among a population of military veterans with PTSD. Fifty-two veterans living with a PTSD service dog and 44 veterans on a waitlist to receive a service dog were recruited from a database...
