How to Deal with an Aggressive Rescued Dog

The Picketts have adopted a rescued Samoyed German Shepherd Cross named Angel. He is lovely, but he attacks other dogs when out on walks. Dr. Stanley Coren probes them about what they know of his background, and he surmises that he was probably tied outside, where he felt very vulnerable to the attack of other dogs. In that position, he as no alternative but to fight back, and now he always fights dogs. He shows the Picketts how to gradually get Angel to understand that most dogs are friendly.
