service dogs helping veterans

I love dogs, but I had no idea the extent to which they could be trained to help humans. I read a story about a Marine who spent three tours in Iraq, and is struggling with post-traumatic stress disorder (PTSD). He now has a service dog, specially trained to help veterans with PTSD. Some of the ways in which the dog is able to help are incredible.

The story also made me realize how ignorant I was about some of the effects PTSD can have and the daily pain it causes, and makes me even more grateful for the sacrifices our soldiers have made.
