With more and more dogs in the military, people are beginning to realize that dogs can develop post-traumatic stress disorder (PTSD). This disorder is common for soldiers or people who have experienced or witnessed a traumatic event in their lifetime. It can cause them to avoid memories associated with the trauma, have recurrent dreams of the trauma, experience increased arousal and panic attacks when they are reminded of the trauma. Lulu, a dog rescued from battlefields in Iraq and Afghanistan, seems to experience some of these symptoms. Lulu is frightened when in contact with other dogs and children, suggesting that the dog is afraid of quick and unexpected movements. The fact that animals can be affected to such an extent shows how vulnerable humans are to traumatic stress disorder. PTSD can have a life-altering effect on a person's life and as we have seen in this article, on a dog's life too.
