Good news, they do make a difference. I know there are specific dogs trained to be PTSD service dogs. But its funny, I think they sense when they are needed. Same with using horses as therapy. The horses can tell when an individual is disabled. Some animals are some pretty smart creatures. So glad to hear it. Terri what is the pups name?

Reality is determined not by what scientists or anyone else says or believes but by what the evidence reveals to us.
