He had these dogs since they were puppies.

I ran the dogs on the islands on Christmas day, and my pups sister is bigger and stronger when they run up to me she was covered with blood and her tongue was blood red. She had got a squirrel, but the instincts which kick in on an attack are hard to stop. People need to be careful with any dog which has shown aggression toward people and cannot differentiate.....they are dangerous.
