Leigha,

PitBulls are bred to fight. Dog fighting is illegal in most every state but it doesn't stop it from happening. People don't buy pit bulls because they're cute and fluffy. They buy them because they're scary. They buy them for protection. It's unfortunate, but most often they maim family members.

I agree that dogs, especially large breeds, should be trained. But a leopard won't be turned into a house cat because he's trained.

I don't know the original purpose of the breed, but today's purpose is protection - and fighting. And they have been bred accordingly. Anyone who forgets that does so at their peril. A person might have a pit bull for years and it dies of old age never having done anything more 'deadly' than chewing shoes. But are you willing to risk someone's life on it? I'm not.
