The training was clearly explained and if I didn't understand, Jodi would go over it with me. When I took Basil out, after his session, we passed a stranger and he went to bark and I corrected and he stopped right away. He now walks with me, not ahead, and my arm isn't tired. What a nice walk we have. I really got the hang of how to be a better leader of the pack. It is simple and effective. I would only use Bark Busters. The trainer is so nice and wants to teach you how to communicate with your dog and will go out of her way for you.
