There are people who believe, and who post on FR 'pit bull' threads, that pit bulls have locking jaws. After you say 'of course they don't,' Google it to see whether it's obvious to everyone that they don't have locking jaws.
It is extremely difficult to force a pit bull's jaws open if it doesn't want to open it's jaws.
Right, but they aren’t “locking”, just really dang strong and unwilling to release. Its how they’ve been bred.
