My husband and I have two dogs, a Bichon Frise (Daisy) and a Biewer Yorkshire Terrier (Bruiser), who dominated our household due to our reluctance to correct them in fear that the discipline would mean that we did not love our puppies. Due to the lack of discipline and structure in our home, they would bark incessantly when someone came to the door or if they heard a noise, and Bruiser showed signs of aggression towards Daisy. Not only that, they would pull when we would walk them and would not come when called. Although these issues, along with a few others, seem to be pretty minor, as a whole, it made for very frustrated parents! From the moment that Justin came in to our house, the puppies knew who the leader was (and taught us how to assert ourselves as leaders) and they behaved accordingly. We saw such an improvement in our puppies' behaviors as well as their response to us in just one session. After the second session, they both are able to walk at heel and will come when called. All the other issues regarding aggression or anything else we had problems with have been virtually eliminated. We would definitely recommend Justin and Bark Busters for anyone with dogs who would like to have a more peaceful and happy household because it has definitely worked wonders for us and our puppies are a whole lot happier.
