This rumor started with the Doberman, and has since been said about game-bred dogs in general. The concept of an animal's brain swelling or growing too large and somehow causing the animal to "go crazy" is not based in truth in any way.
Their brains grow at the same rate as any other dog, and the only time that a Pit Bull's brain is going to swell is if it receives a serious injury. If an animal's brain were to grow too big for its head, the animal would die.
