I came to dominant dogs because my dog of three years had started to become more aggressive towards other dogs. Leonard showed me that my dogs aggression with other dogs was because my dog was in charge and not me! He showed me in just 5 minutes of being there how to show her who is in charge. Along with training my dog, he also taught me a great deal about myself and how my personality and attitude is reflected in my dog. Real eye opener! I would recommend him to anyone who is experiencing aggression with their dogs!
