Does rotweillerhave lock jaw

Actually this "lock jaw" does not really exist not even in pitties(American Pit Bull). The lock jaw people refer to is actually the muscle that supports the jaw the larger the dogs head the harder the bite in fact rots have the largest bite 365lbs per inch. Lock jaw isn't what it's called it's actually just the dog biting and holding onto it's subject. Rots aren't known for doing this but actually biting repeatably with their massive bite.
