My Pitbull, Steeler, loved Patrick from the moment he came in and we both loved the Bark Busters techniques. I saw noticeable results, by the end of the lesson, Steeler was not rushing the door or jumping on the couch (unless he was invited). Nothing is more natural training than the techniques used by Bark Busters. Patrick not only explained why Bark Busters teaches what they teach, but also made it easy with the demonstrations. I would recommend Bark Busters because they are well organized and I liked the training techniques. I would also recommend that everyone with a dog learn how to speak, dog with help of Bark Busters.
