They had a support/stress dog at several of the bases I spent time at in Iraq, which I thought was pretty cool. They were part of the combat stress medical units if I recall. I don't know the true efficacy, but a close friend of mine who was in pretty bad shape said the dog helped cheer him up. If nothing else just having the opportunity to pet a dog and forget about things for a bit must have been nice.
