A pittbull CAN break a femur with one bite. Their jaws are powerful. Unfortunatly, this attracts owners who want the dog for it's strength and fighting potential, which leads to a higher precentage of nasty pitts, and thus the bad reputation for attacks.
If they're raised and bred well, they can be absolutely wonderful dogs. Believe it or not, a well-raised pitbull is very good around small children. Because they were historically bred for fighting, they have a tremendous threshhold for pain. The kid can poke and pull on the dog all it wants, and the dog won't care. Any nasty temperament a dog has is from bad breeding or from an owner who teaches it to be basty.
Yar. In England I believe they're referred to as "nanny dogs" cause of their favorable temperment toward children. Which, would be nice if I were a child! :)
