Biting year old pitt
My 12 month old pitt bull male (neutered) has begun to bite. We have corrected him earlier when he growls or barks aggressively. He is a sweet dog, minds well until he is off leash and running with our other two dogs, female. They all 3 have begun to run toward someone walking their dog. The male jumps up and bites at the human, not the dog. Obviously we need to keep him on the leash, but what do we do to break this behavior. I am beginning to think we need to give him up.
We got him when he was 5 months old.
