New Research to Use Brain Imaging to Measure Human-Dog Interaction

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) will fund a new study conducted by Indiana University-Bloomington’s School of Public Health researchers Drs. Alyce Fly, Ming Li, and Katharine Watson. The researchers aim to characterize the impact of pet ownership on the adult gut microbiota, which has been shown to influence the role of cardiovascular disease (CVD) development. Fly, Li, and Watson hypothesize that differences in the gut microbiota of cat and dog owners relative to non-owners are associated with reduced CVD risk. “Studies have found that living with cats or dogs imparts health benefits associated with the gut microbiota of infants and children, such as a reduced risk of developing asthma and other immune-related diseases,” Principal Investigator Katharine Watson, MA BVMS, explains. “Studies have also shown that gut microbiota health is associated with reduced cardiovascular disease (CVD) risk. However, it is not known whether the gut microbiota of adult pet owners differs from non-owners. As pet ownership is associated with benefits to the gut microbiota of infants, it is probable that adults who live with pets may have similar benefits and that these may play a role in CVD risk reduction.” “HABRI is proud to support this novel research into the relationship between pet ownership, gut microbiota, and risk of developing cardiovascular disease,” HABRI Executive Director Steven Feldman notes. “Science tells us that pets can influence the physical and mental health of owners, and this project will explore an important aspect of the physiological underpinnings of the human-animal bond.” Drs. Alyce Fly and Ming Li will serve as co-investigators on the study which may help to determine whether living with a cat or dog is associated with a richer and more diverse adult gut microbiome and whether this, in turn, may mediate reduced prevalence of CVD. CVD is the leading cause of death and disability and the most common non-communicable disease...

The Human Animal Bond Research Institute (HABRI) announced results of a new publication led by researchers at the Telethon Kids Institute and The University of Western Australia (UWA), which found a simple health intervention using text messaging may encourage children to spend more time being physically active with their family dog. This randomized controlled trial was published in the journal BMC Pediatrics. “We found texting parents to remind them of how easy and important it is to be active with the family dog is a low-cost intervention with the potential to boost public health, which can be easily implemented across entire communities,” said Telethon Kids and UWA Associate Professor Hayley Christian, Principal Investigator on the study. “Interventions, policies and community programs should capitalize on the high level of dog ownership and incorporate dog walking or play into physical activity campaigns.” “This study shows that a simple text message reminder to play or walk with the family dog can result in increased physical activity for children and their caregivers,” said Steven Feldman, President of HABRI. “HABRI looks forward to raising awareness of the results of this publication which outline new and simple ways to encourage families to spend more quality time playing with and walking their dogs.” Dr. Christian and colleagues led the Play Spaces and Environments for Children’s Physical Activity’ (PLAYCE) PAWS mHealth intervention, a randomized controlled trial conducted in Perth, Western Australia. Families of children between the ages of 5 and 10 with a family dog were placed into three experiment groups: one group of parents received regular text reminders about family play with the dog, one group received text reminders while also receiving a dog pedometer to further engage them with the dog, and the third group carried on as usual. This study was the first of its kind to utilize a mobile-based dog-facilitated strategy to increase children’s...
