A couple of my friends have pitbulls. Although they are the most hyper dogs i've ever encountered, i have no problem with them. It's obvious that they are REALLY muscular and could really do some damage if they attacked, but that doesnt mean they are going to do it. As far as I'm concerned, any animal can be agressive or the biggest pussy in the world depending on training and the amount of given attention.

If your dog bites or attacks someone... it gets put to sleep... end of story.
