If dog's understood what "no" or "stop" really meant, dog trainer would not be much of a career would it? We teach you how to talk to your dog so it understand you when you are trying to educated and teach your dog how to behave. We do it all in your home and in about two hours. Here is what one of my clients had to say, "The presentation was awesome, informative, logical and very educational. Patrick packed in a lot of information while he was here. Bark Busters delivered unbelievable results. We never imagined any method could be so effective in such a short amount of time. Patrick was very good and we were able to obtain results ourselves quickly. Our puppy is happy knowing he is pleasing us. We were totally surprised to experience the method and how effective Bark Busters is. We have told many people about Bark Busters and how amazing and effective Bark Busters is. This is my first puppy and until I called Bark Busters I didn't even know what to do to achieve the results I wanted. Thanks to Bark Busters, we know communicate effectively. I love it!"
