I delivered pizzas while I was in college. I can't begin to tell you the number of times someone would tell me, "Oh, he's the sweetest dog there is - he'd never hurt anybody" while the animal is foaming and snarling and throwing itself against the door or straining the owner's arm out of the socket at the end of a leash to try and attack me. And it wasn't always pit bulls.
Too true. My Chihuahua thinks he is a rotwieller and would just as soon bite you as look at you. But I keep a very short chain on him. He is a dog; dogs bite. Only a moroon would think their dog is incapable of biting anyone.
Oh I've heard this 1000 times, and I've been bitten 3 times by dogs that would "lick you to death" according to their shocked and in some neighborhoods, lawsuit paranoid owners :)
Note to pet owners: Your dog won't bite you, HE KNOWS YOU!!
Don't assume anything.
BTW, my bites came from a Dalmation, a giant ugly poodle, and Chesapeak retriever.
