John explained the techniques so thoroughly that we understood them right away. We definitely observed noticeable results. Before John left, we saw changes in both dogs. We couldn't believe it. We learned a lot about our dogs by going through the training. We had a fun time while learning how to control our problems. Yes, we would recommend Bark Busters to our friends and neighbors. We will tell everyone about Bark Busters and especially John, our trainer, he was wonderful. We can't believe the change in our dogs behavior after just one lesson. Our house is now quiet and we are in control, not them. It's unbelievable how well this worked. No more sibling rivalry between our dogs. It's a pleasant home now with them.
