First off, this dog was "part pit bull terrier". Funny how they don't mention what the other parts were. The sensationalistic media isn't interested in golden retriever attacks.
Secondly, the worst thing you can do is run from a dog you think may be aggressive. You should stand still. Any movement may trigger the dog's prey drive or be seen as threatening to the dog.
Lastly, unless the dog's owner sent the dog out to attack, they should not serve jail time. I think fines should suffice. No one owns a dog with the intent of the dog killing children.
