Yes, Spaten's problem is not liking new people. He is fine with the immediate family that lives here, my parents, then my brother comes over and he's ok with him because my brother yelled at him not to bite and ever since he has been fine with my brother. He was born with the leg problems. His back paws face out to the sides, instead of facing forwards. His body language with new people is a low growl, tail up, ears back with a forward stance. We had a trainer come by and she said to walk him around on a halty. That was it. So I put him away in my bedroom or outside when people come over.
