The other thing I have heard is the one I'm sure most have heard is about their jaws locking while attacking. Is there any truth to these?
The "locking jaws" is a complete myth. It's not true.

I've never heard anything about their brain growing too large for their cranial cavity thus causing them to attack, but again, irresponsible breeding and irresponsible dog "owners" (I hesitate to call them that) are THE cause of the Pit Bull's bad reputation, along with the media.

This is my uncle's Pit, Queenie. What a vicious animal, eh?
