Research Highlights the Role of Service Dogs in Slowing Cellular Aging in Female Veterans
A pioneering study reveals that training service dogs can help slow cellular aging and improve mental health in female military veterans, offering a promising non-pharmacological approach to PTSD treatment.
A recent groundbreaking study has revealed that working with service dogs may contribute to slowing down biological aging in women. This research, focused on female veterans in the United States, is among the first to explore how involvement in training service dogs impacts cellular health and stress levels. By assessing biological indicators such as telomere length—a marker of cellular aging—and heart rate variability, the study sheds light on the physiological effects of animal-assisted interventions.
The study, conducted by researchers from Florida Atlantic University in collaboration with the University of Maryland School of Nursing, the Medical College of Georgia, and Warrior Canine Connection, examined women with post-traumatic stress disorder (PTSD). These women either trained service dogs for fellow veterans or watched dog training videos as a control activity. Over eight weeks, participants engaged in weekly sessions, with assessments carried out before, during, and after the intervention.
Results showed that veterans who trained service dogs experienced an increase in telomere length, suggesting a slowdown in cellular aging. Conversely, the control group saw a decrease, indicating accelerated aging. Notably, those with combat experience benefited the most, with significant telomere preservation. Psychologically, both groups experienced reductions in PTSD symptoms, anxiety, and perceived stress, emphasizing the therapeutic value of engagement in structured activities.
Cheryl Krause-Parello, Ph.D., the lead author, highlights the importance of nontraditional therapies. She suggests that animal-assisted activities can provide emotional safety and stability for female veterans, especially those unable to care for a service animal long-term. The skills gained during service dog training, such as positive reinforcement, might also strengthen bonds with existing pets, adding further emotional support.
Overall, this study emphasizes that non-pharmacological interventions like service dog training hold promise in mitigating the physical and psychological effects of stress and trauma in female veterans. The findings encourage further exploration of personalized, holistic approaches to veteran care.
