There is a great story on the National Public Radio (NPR) web site, which you can both read and listen to, titled Injured Veteran Reunites With Bomb Dog And Medic. It's about a young woman veteran, severely injured in the Iraq war, who came to adopt her bomb-sniffing dog Rex and marry the medic who saved her life. What a story!
This woman and her husband and dog now live on a farm/ranch in Pennsylvania. The last paragraph of the story is subtitled "Finding Peace with Animals."
It's a good read.
