How are Therapy Animals effected by their work?

[Catherine]

I think even the reptiles like to be with us. I know bearded dragons love people and my snakes like to have me around. There may not be many(if any) therapy reptiles, but like all the other animals in our lives they do make us feel better.

Dogs of course are the best at it. They actually want to work for us.
I am sure we did not bring dogs in from the wild, they came in voluntarily because they could see that we needed them. We still need them.
