Post-traumatic stress disorder (PTSD) is not just reserved for humans - a growing body of research indicates that dogs can also suffer from the disorder. In particular, military dogs and those working in extreme conditions, such as search and rescue dogs, are exposed to traumatic experiences that can lead to the development of PTSD symptoms. In recent years, a number of studies have been conducted to understand this issue and develop effective strategies for diagnosing and treating PTSD in dogs.
