In my experience small dogs are much more likely to bite then big dogs, but I'd rather be bitten or attacked 10 times by a cocker spaniel then once by a pit bull or other strong/bigger breed.

Who's more dangerous to you Pee Wee Herman or John Cena? If Michael Jackson or Mike Tyson snap who do you want to fight?

I'm not against Pit Bulls at all or for banning them, but to say they aren't dangerous is stupid. All big breeds are dangerous because of the damage they can inflict. My Great Pyr is known as a gentle giant but I know he is dangerous just because of his size.
