I'm willing to bet I've met and handled more dogs - no, VASTLY more - dogs than you. Doing a really quick WAG, I'll estimate that I've met and handled roughly 25,000 dogs in my more than ten years as a veterinarian.
Never been bitten by a pit. Not once. I have met a few aggressive ones and I'll be the first to admit that an aggressive pit is terrifying - but those dogs were the exception.
I guess what I'm saying is that I have the experience and first hand knowledge to say that I don't have a problem with pits.
Oh yeah, you have handled many many many more dogs than I, but I dont see where that is relavent.
