It's definately the owner not the dog. When they're bred for fighting the sick bastards who breed them torment the life out of them by picking them up by their ears and swinging them around, or stumping cigarettes out on them, or hitting them constantly with a stick. You can't blame the poor dog for attacking a human, they've been pushed to their limit and that's why they snap, it really upsets me. The pitbulls who end up in rescue centers are the ones which have been abandoned because they're not as agressive as the owner wants them to be. And when they do turn out agressive and bite somebody or kill another dog the poor things are either shot or given a lethal injection, the dog can't win.

Look at these pics, I believe this is the true nature of the Pitbull before they are pushed and pushed and pushed until they snap.
