Tank is a wonderful 5 year old purebred German shepherd. We have had him since he was 10 weeks old. He has undergone numerous trainings over the years and is a very good dog. Unfortunately, when he was young he was attacked twice by other dogs, resulting in some dog aggression. And now, with the arrival of our 1 year old daughter he has become more aggressive and defensive towards strangers and other dogs. We cannot imagine having to keep him in a muzzle for long periods of time while on walks or while having visitors and we feel we have tried every possible avenue to fix these issues. With a very heavy heart we have decided to find him a better suited home and hope that he can flourish like we know he can.
