Go out to Google, type in "Pit Bull Attacks" and see what kind of response you get.
You'll get stories about maulings, cripplings, pack mayhem and killings done by pit bulls. Thousands of them.
Then type in "Bichon Frise Attacks". (That's the breed I own.)
You'll get stories of allergies, sicknesses, and illnesses that Bichon Frises suffer.
You pit bull owners are in denial. Any dog breed that has to be constantly supervised so that it doesn't pierce the jugular of an old lady walking down the street is a breed that is destined for the dust bin.
Enjoy them while you can, if they don't kill you first.
