Patrick's in Santa Rosa but he is totally worth the hour drive. Our dog was aggressive with other dogs. We left her with him for three weeks, and she came back a different dog -- heeling off-leash, coming when we called her, and able to play with other dogs. I can't recommend him enough. He's been training dogs for fifty years or something like that and he's amazing. He really knows how to deal with behavioral issues like aggression. Plus our dog loves him.
