All dogs have the potential to be mean if they are mistreated or handled in an aggressive way. The difference is that some of these dogs like the Pit and the Rott are very powerful creatures! And, people have breed them to be aggressive.
All the hype on the Pit is crazy! The dogs aren't bad, the people who make them mean are!
I had a pit puppy and my landlords asked me to get rid of it or move because they were afraid of lawsuit if anything happened on their property. This dog was so sweet and wouldn't hurt a flea. She was much milder than my Silky Terriorist,Angus, who was allowed to stay.He is cute and doesn't look threatening!! Ha! little yorkies and silkies can get down right mean!
So, you can't judge a dog by his bark or bite, right?
