No intelligent parent would leave any child unsupervised with any dog. Dogs are not human, even the most docile dog can snap.
Humans can attack children, too, and often do. It's a matter of knowing who to trust, regardless of the number of legs.
Usually, aggressive dogs, like aggressive humans, are made that way, not born that way.
I strongly disagree. Again...........
It is the breed. How many times have you read "Beagle kills child"? Or "Cocker Spaniel mauls senior citizen to death"?
And after nearly every local pit bull attack I've read the owners always say, "We never trained him to be aggressive" or "He's never done that before".
Many dog breeds bite, that's a fact. But few, if any of them of them will maul and kill to the extent that pit bulls do.
