With the right owner and a pit with papers, they can be excellent dogs. The only real danger is that they are like wolverines..in the sense..that they have locking jaws and their bite is the strongest(pounds of pressure per square inch)that any other breed. unlike other dogs, pits wont bite and let go...they hold on and shake. people dont get injured badly or die from pit attacks because of lacerations..they usually get a broken limb or in some cases a dislocated shoulder..babies that are killed by pits die from broken necks or crushed skulls...not tearing bites. This is why state laws often require muzzles.Not because the breed is mean..but because,in case of an attack, an injury from a Pit tends to be more serious then any other breed. But a Staffordshire Bull Terrier that doesnt come from some random,junkyard breeder can be a wonderful dog. they arent as jumpy or flighty then alot of breeds. they dont spazz out as much. Pits and Dobies have much worse reputations then they deserve and we can thank the dispicable world of dog fighting for this.
