Way to go, Taz!!
I got my Yorkie a week and a half ago. From the first day, I have Lexi ring the Tell Bell every time before we go out. (I have to hold her paw and do it myself.) So you are giving me hope that one day, she will do it herself!
At least she isn't ringing it on her own, for fun. I know they can test you, and you have to bring them out every time they ring it.
