PhD Defence: The interaction between service dogs and veterans/first aid responders with Posttraumatic Stress Disorder (PTSD)

Veterans, police officers, and other uniformed personnel can develop Post Traumatic Stress Disorder (PTSD) as a result of their work. PTSD is the result of one or more very stressful or traumatic event. Common symptoms include nightmares, anxiety, and depression, which means PTSD can have a very negative impact on a person's life and that of their loved ones.

In order to gain a better understanding regarding the treatment of PTSD, this PhD research investigated the influence of service dogs on the symptoms of PTSD. It was found that by using the service dog, people with PTSD feel better and experience fewer symptoms. However, we have not been able to determine that this also causes physical changes, like altered salivary cortisol levels, or increases daily exercise.

In addition, we looked at the effects of assistance work on the service dogs themselves. This study showed that the dogs we examined did not show signs of chronic stress. Further research must show whether this applies to all PTSD service dogs and in what form dogs and if results stay the same over time.

In summary, the assignment of a service dog changes the lives of people with PTSD for the better. It provides an improved sense of well-being in the veterans. Service dogs themselves furthermore do not seem to experience prolonged exposure to stress due to their work. It therefore seems advisable to continue the placement of service dogs to improve the well-being of people with PTSD. Further research on service dogs is however advisable to broaden the understanding of the use of service dogs.
