I just went to the doctors...There was a little girl in tears because she had gone to pet the staffy and s/he bit her. That makes me sad because I can see both sides. The kid wanted to pet the dog, and the dog was grouchy and maybe scared. In that situation, without knowing everyone involved, who's side do you take?
I wish people would muzzle dogs that have a tendency to nip when frightened, would really help things.
