My dogs have never been to obedience classes, but I've heard from many people that have taken their dogs there and have been very successful. I think puppy classes for Gracie will help out a lot.

She is beginning to reach the puppy-teenager stage though... I think now would be a good time to get her into some classes because the longer you wait the harder it will be to train her, and 'come' and 'stay' are two of the most important commands a dog should learn!
