The training techniques were so easy to understand and very easy to implement. Otis, my St. Bernard, would NEVER heel before, but by the end of the session, he heeled and is even better today! I was very pleased with the natural training techniques used by Bark Busters. Never has training been easier. The experience was extremely interesting -- especially to see the changes minute by minute! I recommend Bark Busters everyday. The experience was wonderful and is so easy to follow through with daily. I had a very large dog with bad behavior. By the time Lisa left, he was a different dog!!!
