Pit Bulls account for more attacks because they are used to fights and be aggressive, and therefor there are more aggressive ones around than other breeds which is because of their powerful build. There are just more aggressive ones out there because of the owners habits. It makes it more likely. If freaking minature pinchers were used that way, there would be more little ass bites as well.
