The German Shepard is often a misunderstood breed. Colin's no nonsense and patient approach helped make the trainings both meaningful and fun. Bark Busters personalized style addressed issues such as walking on the leash without pulling, door manners and attentiveness training. He helped me acknowledge some behaviors that I unknowingly encouraged that contributed to her ways. Jewel is now a favorite at the dog park and I have the confidence that she can shine in a variety of situations. Colin included my girlfriend as part of the training team. Bark Busters =happy owners and happy dogs!
