Pit bulls are the most misunderstood dogs in the United States. They're also the dogs most likely to be euthanized in municipal shelters, most likely to be banned by landlords and insurance companies, and most likely to be turned away from doggy daycares — almost entirely because of a reputation built on selective media coverage, mistaken-breed reporting, and a few decades of bad legislation.
The short version: pit bulls have the reputation they have because of how humans have treated them, not because of who they are. Here's the longer version, with the data.
First: "pit bull" isn't really a breed
When people say "pit bull," they usually mean any one of four overlapping things:
- American Pit Bull Terrier (UKC-recognized breed)
- American Staffordshire Terrier (AKC-recognized breed)
- Staffordshire Bull Terrier (AKC-recognized breed)
- Any short-coated, blocky-headed, medium-sized dog of mixed background — i.e., the largest single visual category in American shelters
A 2015 University of Florida study found that shelter staff identifying dogs as "pit bull" were wrong about the dog's actual genetic breed roughly 60% of the time. That matters because every bite statistic and dog-bite-fatality news headline that says "pit bull" is using a visual guess, not a genetic test. Mislabeling is the rule, not the exception.
Where the reputation actually came from
Three things converged:
1. Dogfighting subculture (1970s–1990s). Underground dogfighting exploded in the late 20th century, and pit bulls — bred originally for tenacity in bull-baiting and later as nanny dogs ("The Nanny Dog" was a real marketing image in the 1900s) — were the breed of choice for breeders who wanted dogs that wouldn't quit. This is real, and it produced a population of unsocialized dogs in the wrong hands.
2. Selective media coverage. A 2008 National Canine Research Council study compared news coverage of four real bite incidents over four days in 2007. The pit bull incident got 230 national articles; the others, all involving different breeds, got fewer than 5 articles each total. Bites by other breeds simply aren't news; pit bull bites are.
3. Breed-specific legislation (BSL). Cities and insurance carriers started banning pit bulls in the 1980s and 1990s, which made the breed harder to rehome, more likely to end up in shelters, and more likely to be owned by people specifically wanting an "intimidating" dog. The legislation produced the very population it claimed to be reacting to.
What the actual data says
- Temperament tests. The American Temperament Test Society scores pit bulls at 86.7% pass rate — higher than golden retrievers (85.6%), border collies (81.6%), and beagles (79.9%). The test measures stability under stress, reactivity to strangers, and aggression triggers.
- CDC's own statement. The Centers for Disease Control stopped tracking dog bite fatalities by breed in the early 2000s because their own researchers concluded breed identification in bite reports was too unreliable to be meaningful.
- AVMA position. The American Veterinary Medical Association, the American Bar Association, the American Society for the Prevention of Cruelty to Animals (ASPCA), and the National Animal Control Association all oppose breed-specific legislation as ineffective and unsupported by data.
- Where BSL has been repealed, like in the UK's ongoing debate and in dozens of US cities that have rolled it back, bite rates didn't change. Because breed wasn't driving the bite rates in the first place.
Why pit bulls fill American shelters
Pit-bull-type dogs make up 20–40% of the dogs in most US shelters. The reasons are structural, not behavioral:
- BSL and rental restrictions make it harder for responsible owners to keep them.
- Insurance bans force families to surrender otherwise well-loved family dogs when they move.
- Unethical backyard breeders churn out litters that get dumped when the puppies aren't sellable.
- Visual mislabeling means many "pit bulls" in shelter statistics are actually boxer mixes, mastiff mixes, or American bulldogs.
- Long stays because the public is reluctant to adopt — this is the cruelest part. Stable, friendly, well-evaluated dogs sit in kennels for months waiting for someone willing to look past the label.
Shelters running PawMates Pro often use the platform's behavioral evaluation tools and compatibility matching to help potential adopters look past breed and focus on the dog's actual temperament — which is what predicts how the dog will fit into a home.
Are pit bulls "good with kids"?
Properly socialized, evaluated, and managed pit-bull-type dogs are as good with kids as any other breed — often better, because the breeds blended into "pit bull" populations were historically family farm dogs. Any dog of any breed can bite, and the bite-prevention rules apply equally:
- Never leave any dog unsupervised with any child
- Teach kids to respect a dog's space
- Have a trainer evaluate any new adult dog with kids in the home before adoption

Frequently asked questions
Are pit bulls more dangerous than other breeds?
No. Temperament tests, the CDC, and major veterinary and legal organizations all agree the data doesn't support that claim.
Do pit bulls have "locking jaws"?
No. This is a persistent myth. Pit bulls have normal canine jaw anatomy — they don't have a locking mechanism, and their bite force is not exceptional compared to similarly sized dogs.
Why are pit bulls banned in some apartments and on some airlines?
Insurance liability — not data. Insurers underwrite based on litigation risk, not bite frequency, and breed-specific litigation history (combined with media coverage above) drove a cycle of bans.
Should a first-time owner adopt a pit bull?
Sometimes. A well-evaluated, foster-tested adult pit bull from a reputable rescue is often easier than a high-energy working breed. A backyard-bred puppy of any breed is harder. See what dog breeds are best for first time dog owners.
What about dog parks?
Pit bulls vary widely in dog-dog sociability. Many are dog-friendly into adulthood; many are not, particularly with same-sex dogs. The shelter's behavioral evaluation is the best predictor. Foster-to-adopt arrangements let you find out before committing.
Bottom line
Pit bulls get a bad rap because of selective media coverage, misidentification, and decades of bad policy — not because they're worse dogs. If you adopt one from a shelter that has done a real behavioral evaluation, you're getting a normal dog with a stigma attached, not a problem dog with a label that fits.
