Therapy Dog

I had a meeting today with my potential new boss, who is the therapist that runs the Canine Healers at Excelsior. In addition to Interviewing for the open position for Group Living Counselor in Edge Point, I expressed my interest in animal assisted therapy, and my desire to 1. Train Amos to be a therapy dog, and 2. to specialize in animal assisted therapy. She told me to look at TDI (Therapy Dogs International), or Delta, which are the two most recognized certifications for therapy dogs.

I was looking at the behavior requirements for TDI, and I'm feeling a little bit discouraged that Amos will be able to become a therapy dog. There are several things he can do, but several he just can't.

1. Greeting people and sitting politely for petting. Amos is just too exuberant, and happy to see everybody. I've worked with him with this...
2. The dog will welcome being groomed and examined and will permit a stranger such as a vet, groomer or friend of the owner to do so. Yeah right... ain't gonna happen. Amos is TERRIFIED of being groomed, and totally flips his shit every time he sees the brush, unless I have him in a small enclosed room (such as the bathroom), and am giving him treats every 30 seconds and am speaking sweetly to him... and even then its a bit of a struggle.
3. Coming when called.... needs some work. He's just inconsistent, which I know is my fault, as I'm inconsistent as well.

These are the one's that I'm worried about. I keep telling myself manners can be learned.... It just might be a bit of a process.... Le sigh.
