That is such a cool thing. Congratulations!!! That is so wonderful!
My poodle, Bull, that just had the surgery was a pet therapy dog when I got him. He was at the hospital where I worked sitting up in someone's lap in the IV room when I first saw him. I convinced them to sell him to me.
I have taken him to the nursing home. He is such a good dog, unlike his sister who would lick them to death and in the face. He will just sit there. It is very rewarding and you will love it.
