New Research to Analyze Therapy Dog Behavior to Improve Welfare for Animal-Assisted Interventions

The Human Animal Bond Research Institute (HABRI) today announced funding for a new research project at Colorado State University to study the impact of temperament and stress on the health and success of working dogs. This pilot study aims to measure the Allostatic Load (AL) of dogs, which is understood as the ‘wear and tear’ on the body due to chronic or frequent stressors. Widely published in human health literature, AL in humans is affected by genetics and personality, and high AL is a predictor of negative health outcomes including heart disease and cognitive decline. After successfully validating AL in primates, the research team seeks to validate canine AL for the first time. “Developing a reliable method of measuring chronic stress will help ensure we are taking proper care of working dogs as well as pet dogs,” said the Principal Investigator of this project, Barbara Wolfe, DVM, Ph.D., DACZM, Colorado State University. “If successful, this tool could be utilized to predict success in working dogs and identify when working dogs are experiencing unhealthy levels of stress.” This study will analyze early life events and lifestyle factors that may influence AL in Labrador Retrievers raised to be trained as guide dogs as well as Labrador Retrievers raised as pets. Researchers will use blood sampling to compare biomarkers associated with AL to these lifestyle and event factors to determine any association between AL and potential stressors. While many studies to date have used a single biomarker, such as cortisol, to determine canine stress, measuring AL tests multiple biomarkers of stress which allows for a more accurate measure of the accumulation of stress over time. “This project reflects HABRI’s deep commitment to animal care and welfare,” said Steven Feldman, President of HABRI. “Understanding how to improve the lives of our canine companions is crucial to strengthening the human-animal bond.”

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...

The Human Animal Bond Research Institute (HABRI) announced today it has awarded a $52,204 grant to the University of Missouri for a new study, Shelter Cat Adoption in Families of Children with Autism: Impact on Children’s Social Skills and Anxiety as well as Cat Stress. This study will examine the effect of the introduction of a shelter cat on social skills and anxiety in children with autism, and on stress levels for the cats themselves. “Preliminary research demonstrates the effectiveness of companion animal interaction on alleviating social skills deficits and anxiety in children with autism spectrum disorder (ASD),” said the study’s Principal Investigator, Gretchen Carlisle, PhD, College of Veterinary Medicine, University of Missouri. “While many studies have focused on the impact of dogs on children with ASD, this study aims to determine the beneficial impacts of a pet cat on children with autism and their families, as the temperament and the ease of care for cats compared to other animals may increase the likelihood of a positive outcome for the children, the cats and the family as a whole.” In addition to HABRI’s grant award, the PIs have also received funding from the Winn Feline Foundation in the amount of $25,000. The combined funding from Winn Feline and HABRI have enabled the PIs to expand the sample size and add the support of a statistician, which will greatly enhance the power of the study and hopefully result in more definitive and robust findings. “Winn Feline Foundation is thrilled to have initially supported this important study on the human-cat bond and to hear of HABRI’s grant award. Their additional support will strengthen the study’s findings”, commented Winn’s Executive Director Dr. Vicki Thayer. “This significant project evaluating the effects and benefits of adoption of cats by children and families with ASD fits our mission and values”. Using a two-group, randomized, repeated measures design with a delayed treatment...
