It was easy to follow along with the instructions given to us and if we looked lost or confused on what to do next during the exercises, Dick guided us through without us having to ask. We absolutely noticed favorable results before the end of our first lesson. We really appreciate that the techniques don't use physical methods or treats. This was one of the reasons we were drawn to Bark Busters. Dick was very informative and helpful but he also has a sense of humor. He used real experiences to explain topics. We have already recommended Bark Busters to family and friends.
