My dog was attacked by a pitbull last year who ran through the owner's screen door about 200-300 feet away from us and nearly bit my dog. I have a pug, and if it actually got a hold of him he wouldn't survive. So you know what? Fuck pitbulls.
Yea, they can be nice dogs, but I would NEVER have one around my family with the random agression that I have seen out of them. They are a dog fighting, and there are owners that still treat them that way.
Actually you'd want one for your family. They are one of the most loyal dogs ever. People who abuse them and breed them to fight are scum. I've had plenty putbulls and they've all been amazing, wouldn't want another breed.
