Abstract: PTSD is a mental disability that affects roughly 7% of the general population but up to 31% of combat veterans. In this study the researcher evaluated the understanding of the needs of veterans with PTSD for a service dog, and the impact of service dogs on the quality of life of veterans with PTSD, through the perspective of trainers who work with them. Data were collected in semi-structured interviews with individuals who train service dogs for veterans with PTSD. Data were interpreted using thematic analysis. Three key themes emerged from the data. First, trainers demonstrated a good understanding of the nature of PTSD and the challenges this mental disability has on veterans which helps them train service dogs for mitigation of specific PTSD symptoms. Second, the trainers reported their commitment to creating a strong team bond between the veteran and the service dog to provide individualized assistance, including ongoing support from the training organization. Lastly, trainers articulated their understanding of how service dogs have impacted veterans’ lives in a positive way, while acknowledging that not every veteran would benefit from obtaining a service dog. The findings from the study reinforce extant literature that underscores the potential of using service dogs to assist veterans in mitigating PTSD symptoms and emphasize the potential to improve the quality of life of veterans who use a service dog.
