And yes, they do lock and were used for livestock and large game for many years. Maybe they were initially breeded for dog fighting but were sitll used for above mentioned purposes. The jaw socket is defective in them and it does lock on many many occasions. I've seen one's jaw lock onto a pillow. They had ot wait for him to fall asleep to get the pillow back after prying his jaws open.
