Myth: Pit bulls have locking jaws.
Fact: "Locking jaws" do not exist. No one has ever found a mechanism that enables a dog to lock its jaws. However, a pit bull's strength and determination can make it seem as though the dog's jaws have "locked".

I thought they had locking jaws. I have also herd ppl say they have two sets of teeth. .. I love pitt bulls I hope to own a Bull terrier one day if that counts lol. I love their cute faces!!
