Wow, I didn't know that. I still never see any stories about them, though. Also, there is a big difference between getting snapped by a dog and getting mauled by a dog.
I have been bitten dogs a few times. Tickling my girlfriend in front of the family Shepard was not a good idea. Then all she did was snap my hand. She didn't try to kill me.
I agree... huge difference between a snap and a mauling.
