According to various media outlets, they're killing machines! I'm actually the proud owner of an American Staffordshire Terrier, which is lumped in with the Pitbull bread. They're no more dangerous than your neighbors Chocolate Lab, or Golden Retriever. Its all about how they're raised, just like any human. Pitbulls are perceived as human killers by ignorant people who have never had the chance to be around a responsibly raised Pitbull. It's irresponsible owners who give the breed a bad name. They use the Pitbull bread for fighting and drug house guard dog purposes, due to their tenacity and pure strength.
One ridiculous Pitbull myth is that they have locking jaws, in that they actually have a locking mechanism in their mouths. Come on, do people really believe this? Apparently, people also believe that they become aggressive due to the fact their brains never stop growing. This in turn, makes them out of control when it fills their skull! In closing Pitbulls can be excellent family pets, if raised responsibly.
