The pics of the kid definitely make it look like multiple bites - his entire face is wrecked, and even though he's small, there's no way one bite could have done that.
I'm also going off the story that said the bone was near the dog - if the dog was actively chewing on it, then that's different, although I still don't think warrants as bad an attack as what happened.
