FYI --for others thinking about therapy dog training ...
Basically the dog has to come ready made, ie have the right temperment--rock solid, stable, has to like people and be inately gentle...can deal with surprise, equipment etc etc. it helps if they're not big lickers...You can't really train for a stable temperment.
So they say if you really want to do this work, you should get an adult dog whose temperment is formed. And breed doesn't matter much.
The training is 97% for the handler...and I'd say 97% of THAT is learning how to be a proactive advocate/leader for your dog...not a reactive somnabulant at the other end of the leash.
But that's 97% of any dog training....!!!
Discipline is remembering what you want.
