Here's an interesting video on dog therapy - in Iraq! Apparently the dogs are flown out from the US and help to give some relief to the soldiers in what is undoubtedly (whatever your view of the war) a very stressful situation.
I do wish though that instead of flying dogs in (presumably I am guessing so that they are well trained) that they would adopt dogs off the streets instead. In an earlier post, I wrote about the strict rules the US military has on animals. There are some groups which also try and reunite the dogs with the soldiers once they have returned to the US. In times of stress, the bond that you form with an animal is probably even more profound - and I can't imagine being separated forever from an animal I share my life with, especially knowing that the animal might be in danger.
