New breed of service dog treats inner injuries

An Iraq war veteran suffering from post-traumatic stress disorder was contemplating suicide before Tuesday.

Tuesday the Golden Retriever that is.

Luis Montalvan of New York now credits his three-year-old service dog with saving his life. Tuesday is a psychiatric service dog, a new kind of working dog trained to recognize moods and come to the rescue when their owners are feeling down.

The Wall Street Street Journal reports the story of Luis and Tuesday and how some men behind bars are helping free others from their inner prisons.
