I have been working with my Yorkie for only a short time now and she has been great! We have not had an accident in a few days and I feel my last posting may have been a bit premature since we had just gotten her. She is extremely intelligent and I do not have to use force to get her to do what she is supposed to. She is getting into her crate at night by herself with only a little coaxing and no longer cries. I adore her and I am so proud of her progress
