Pits are the best dogs in the world, ive been breeding them for about 8 years now, they are very alert, priotective have great muscle tone and just look awesome. i specialize in blues if any ones intrested puppies on the way. Any dog no matter the size shape or form will turn on another dog, pits are not vicious if you think that your an idiot any dog will defend its territory against another dog, (why do you think these piss everwhere) my 3 year old son actually rides on of my pits like a horse now if they were vicious who in there right mind would let there son ride one. and in response to the bull bloodline thats not a fighting bloodline, its the person who breeds the dog. thats all a bloodline is, many top breeders like corderio,cash,colby and etc will not let the new owner change the name of the dog so that the puppy will be reconized as one of theres to spread the word of what you can expect from the breeders puppies. bloodlines have nothing to do with fighting. it just lets the new owner somewhat know what the characteristics of the puppy will be like.
