Misty, a five-month-olg German shepherd puppy,goes to the hospital twice a Week,but not to see a veterinarian.At this Veteran's Admistration Hospital,Misty is helping doctor not the other way around.I think it is typical of other kinds of animals as well.In what may seem like a role reversal,animals like Misty are visiting the halls of human illness to relieve a type of pain doctors cannot treat.Their therapy is love, both giving it and helping others return it to them.Doctors should be more careful when working with Misty.
