Pit Bulls do not have any special physical mechanism or enzyme that allows them to “lock” their jaws.

If you compare a Pit Bull skull to a skull of any other dog breed, you can see with the naked eye that both skulls share the same characteristics and general bone structure.

One personality trait of the Pit Bull breed is determination. Whatever Pit Bulls do, they do it with a great deal of enthusiasm, and it is this trait that can make it seem like they have a locking jaw when they bite down on something and are determined not to release it.

Dog-aggression and people-aggression are two distinctive traits and should not be confused. Unless a Pit Bull or any dog has been poorly bred or purposefully trained to attack humans, they generally love people. They are, in fact, one of the most loving, loyal, friendly and dedicated companions you can have.
