New Study to Investigate Impact of Pets on Recovery of the Gut Microbiome Following Antibiotic Regimen in Older Adults

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...

March 14, 2019– The Human Animal Bond Research Institute (HABRI), the Children’s Hospital Colorado and the University of Colorado Anschutz Medical Campus today announced the publication of a pilot study exploring the benefits of animal-assisted activities (AAA) for psychiatrically hospitalized youth with autism spectrum disorder (ASD). “Individuals with autism spectrum disorder have difficulties with communication and socialization skills, and often experience difficulties with emotion dysregulation, which can lead to more intensive intervention services such as psychiatric hospitalization,” said researcher and lead author, Monique Germone, PhD, BCBA, University of Colorado, Children’s Hospital Colorado. “Psychiatric hospital environments can be particularly overwhelming and stressful environments for individuals with ASD, and animal-assisted activity is one of the most widely used complementary forms of treatment in hospital settings. We chose to build on existing science that shows children with ASD demonstrate significantly more positive social-communication behaviors when an animal is present.” Dr. Germone, along with study’s principal investigator Robin Gabriels, PsyD, professor of psychiatry at the University of Colorado School of Medicine recruited participants ages 4-17 years old from the inpatient and partial hospitalization unit of a specialized psychiatric unit for pediatric patients with ASD. A crossover study design, participants attended both the experimental (AAA) and control (novel toy) conditions. Both group sessions occurred in a classroom setting and began with quiet play, followed by social skills group and then participants engaging in either the experimental or control condition. The 10-minute experimental sessions included therapy dog-handler teams. The researchers captured behavioral data via video and used the OHAIRE coding system designed to quantify social communication, and interactions with animals and control objects. Categories...

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.”
