The dog now called a pit bull was built in nineteenth-century Britain, a cross of the old bulldog and terrier stock. Bull-baiting was the original work. When that was outlawed, the same dogs were turned to the pit. Immigrants brought them to the United States in the 1800s, where they became catch dogs, farm dogs, and household companions as often as fighting dogs. The name was never one registry. “Pit bull” is a type: the American Pit Bull Terrier, the American Staffordshire Terrier, the Staffordshire Bull Terrier, and a wide ring of dogs that only look the part. The game dog — the one Shaw PBR’s work turned toward — is the older, purpose-bred animal, not every blocky mixed dog the public now labels a pit bull.

That history is why the traits are what they are. The breed was selected for strength, agility, a high pain tolerance, and the determination to finish what it started. Those are useful traits in a partner and dangerous ones in a dogfight. They are also why a disagreement with another animal can go further than it would with a less driven dog. Dog-aggression in this breed is an inherited tendency, not a training failure and not the same thing as aggression toward people. Human aggression should never be tolerated. Severe shyness and instability are not typical either. A dog with those traits is a poor representative and should not be placed.

What the history does not cancel is the temperament people actually live with. Many pit bulls are easy on the couch once they settle, and rambunctious until they do. Maturity can come late, at two or three years. They stay playful for life, and a lot of them are natural clowns. Most want human attention badly enough to think they are lap dogs. Goofy is not soft. They are smart, and they will take a mile for every inch you give them. Clear, consistent obedience is not optional.

Neither is the world outside the yard. The breed carries a stigma that took hold in the 1980s and never really lifted. Homeowners’ policies often exclude them. Breed-specific laws ban them in too many cities. A bite, or even a fight the pit bull did not start, is almost always charged to the pit bull, and the dog is the one that pays. Every bad incident is used against the people who own these dogs responsibly. That is part of what you take on.

In a home with more than one dog, the precautions follow from the history. A fight can start suddenly, and the warning can be quieter than in other breeds. Two dogs can be friends for years, related, sleeping together, playing, even eating from the same bowl — which we do not recommend — and still turn on each other. When it is over they may act like friends again. That does not make the fight minor. Pit bulls can inflict serious injury on another animal. Supervise them together. Crate them separately when you cannot. Know how you will separate a fight before you need to, and keep the tools for that emergency where you can reach them. A breaking stick in the house is not a sign of a dogfighter. It is the same kind of preparation as a fire extinguisher.

This is not a breed to take on halfway informed. Learn the history, the dog-aggression, the insurance, the laws, and the energy before you bring one home. This page is a start, not the research.
