>The problem is that dogs do not always recognize young children as humans. They see them as another animal because their little faces are right down on the dogs level. That little piece of info comes right from vets and dog trainers. Even a dog who would never attack an adult will see nothing wrong with attacking a small child.<
There are other dog experts who use the analogy that dogs recognize the adults in the home as alpha, and see themselves as alpha to young children in the home. If a subordinate to the dog gets "out of line", the dog sees nothing wrong with biting the subordinate.
Basically the same idea, expressed in a different way.
