Service Dogs Improving Health
Shows ‘Man’s Best Friend’ May Slow Aging in Women
A new Florida Atlantic-led study shows female veterans training service dogs may help slow cellular aging.
Study participants engaged in service dog training showed increases in telomere length (a marker associated with reduced biological aging), especially among those with combat experience. Biological and psychological stress indicators were measured from saliva samples, tracked heart rate variability and questionnaires to assess PTSD symptoms, perceived stress and anxiety.
“Female veterans face unique reintegration challenges that are often overlooked, and traditional PTSD treatments don’t always meet their needs,” said Cheryl Krause-Parello, Ph.D. “Nontraditional approaches like connecting with animals can offer meaningful support. … This research underscores the power of service dog training as a meaningful, non-pharmacological intervention to support the health and healing of female veterans with PTSD. It opens the door to more personalized approaches that nurture both the mind and body.”
