Calling Bark Busters was the best decision we made to get out very active and very determined puppy so that she learned that she was not going to be the head of our home. With proper tools and education it is not necessary to ever raise a hand except to pet your four legged family member. It is so nice that when we tell her to go to bed, or to come that she responds. We did go to one place to allow for socialization which is in our case a necessity for our pet as she was aggressive to other pets/animals since socialization and the tools that Lisa gave us our puppy no longer responds with aggressive behavior.
