You are going to love your Yorkie!! I have no experience with therapy dogs, but I know there are plenty of people on here that do. I'm starting a puppy training classes next week. I went to one years ago, but I definitely need another one. I can say that I'm amazed at how quickly Sunni does pick up new commands. Some require lots and lots of repeats, but she does get them. I bet your new dog will be amazing! Good luck, and congratulations on one of the most lovable dogs you will ever have the joy or raising
