No, you only hear about extreme mauling cases on the news (you won't hear about a simple dog nip), and since pits have incredibly strong jaws, their bites cause a lot more damage, and yes, they probably do attack more often than other dogs, however, if you think of the sheer number of pitbulls in homes, and the very small amount of mauling incidents, it's still less than 1% of pitbulls who do this.
