My sweet little Violet is the most adorable and loving pit bull on the planet. And I have met LOTS of pit bulls. I have met sweet ones and I have met some that were absolute horrors. However, I have NEVER met one that was inherently bad without the human in the relationship reinforcing it. Pibbles get a bad reputation but I can say without a doubt that there is not a more loving and loyal dog on earth.
Pit Bulls, Yes! Pit Bulls and Parolee (http://www.vrcpitbull.net/dog/)s is one of my favorite shows.
My roommate LOVES that show. I, however, could never really get into it
