At 5 months of age I knew I was in trouble. Rocko was taking over the house with his high energy and an intense play. He was staring fights with my other dogs and getting more and more out of hand. I knew Jennifer as she had rehabilitated an owner surrendered dog that I had adopted years ago. Jennifer is a canine behaviorist had shown me the best way to manage an aggressive dog. With Rocko she was able to bring our family into a wonderful harmony.
