She should have woken up when the baby cried yes, but also, even though the child was too young to understand what was happening and really fight back, I'm sure it moved around quite a bit, as the dog also did I'm sure. So there's a baby crying, MOST LIKELY a dog snarling, and your bed moving, and you didn't hear or feel it. Yet you heard someone knocking on the door.
Plus, this dog has showsn DA repeatedly. It may not have shown HA, but to a dog that's never encountered a baby, would it really consider it a "human"?
Excellent post pitbullmamanatl. I've read a few articles on here about an "aggressive pit bull" that had pictures of severely mixed breed dogs. Some not even showing signs of being APBT
