I'm not particularly impressed by Therapy Dog as evidence of trainer skill. A fair number of dogs can pass admirably with nothing more than good manners training and natural solid non-reactive temperament.

This is starting to explain why she has such a need to talk up her training skill. She has reason to be insecure. She has 3 well-bred Goldens.
Meanwhile, I have a Chow mix, not famous for getting along with other dogs and known for territory issues, that I got at 11 months who apparently hadn't been socialized well. All told, Jim and I have worked wonders with her.
