I just watched another show of his, and he took a pitt/shepard mix that was very aggressive and brought him to his home to interact with his pack and it was just amazing!! I think he has a very good training method and it does seem to work! He trains the owner, more than the dog! we are always saying "it is not the dog, but the owner" and he is fixing that!! I am going to start using his methods! i love it!!
