We had read several dog training books, but John explained the reasoning behind the techniques and made it easy to follow. The results were immediate! We were stunned that after just two and a half hours, both of our Boxers were calm and eager to learn. We were pleased with Bark Busters natural training methods. Everything is a body language game, so attitude is everything. No amount of yelling or force could ever compare. The training experience was very enjoyable, especially because the outcome was immediate. John was very friendly and fun to have in our home. We are looking forward to our next training session. Early on I was able to walk both of our 75 pound plus Boxers without pulling. Amazing, simply amazing! Our stubborn 18 month old came running right into the house when called. We're so happy. We have already recommended Bark Busters to people we know.
