The legal definition of a pit bull is a class of dogs that includes several breeds: American pit bull terrier, American Staffordshire terrier, Staffordshire bull terrier and any other pure bred or mixed breed dog that is a combination of these dogs. Progressive legislation also includes the American bulldog,1 a closely related breed that shares the same blood sport heritage of bull-baiting. In 1999, the United Kennel Club became the only major kennel club that recognizes the American bulldog breed.

In the State of Ohio, the legal definition of a pit bull is a "breed of dog commonly known as a pit bull."2 The American bulldog became part of this definition after a series of appellate court rulings, The State of Ohio v. Anderson (1991) and Toledo, Ohio v. Paul Tellings (2007). Weight and shape can vary significantly amongst pit bulls, from 35 to 100 plus pounds.3 (Please see Disguise Breed Name to learn more about the deliberate renaming and mislabeling of pit bulls throughout the last century.)

Q: What is the history of the pit bull?

The phenotypes of dogs that share the common definition of "pit bull" derive their heritage from the Bullenbeisser, "the Butcher's Dog," developed through bull-baiting in England, which progressed into a blood sport and a national pastime by 1500.4 Bulldogs were first mentioned by name in 1631, referring to their function rather than a distinct dog breed. By 1800, and through further selective breeding, the bulldog developed into a compact muscular dog characterized by tremendous jaw strength.5

Due to public outrage, the blood sport of bull-baiting was banned in England in 1835. Bulldog owners and breeders then moved to the sport of "ratting," where a number of rats were placed into a pit and wagers were made on how many rats the dog could kill in a certain time period. To increase agility, quickness and prey-drive in the bulldog, ratters crossed the breed with terriers of the time. Essentially, it was the sport of ratting that combined the bulldog and terrier into the modern day pit bull terrier.6

"Other breed historians contend that no such cross was made and point out that the bulldog of the time, the Bullenbeisser, was, in fact, so similar to the modern pit bull that it was simply a matter of selecting the most successful fighters."7 - D. Caroline Coile, Phd, Wiley Publishing, Inc., 2001

On the heels of ratting, dogfighting developed. Pit bulls and dogfighting were exported to America as settlers made their way to the New World. In 1884, the American Kennel Club was formed but rejected the pit bull breed due to their use in dogfighting. In response, Chauncey Z. Bennett formed the United Kennel Club in 1898 to bring formal recognition to the pit bull breed. At that time, Bennett also drew up the rules and regulations for dogfighting, a "pit contest," to bring "organization" to the blood sport.8,9

Q: What is dogfighting and why are pit bulls connected to it?

Pit bulls are the dog of choice amongst dogmen, individuals who fight their pit bulls against other pit bulls. Dogmen consider pit bull terriers, who they commonly call "100% bulldogs," to be the ultimate canine gladiator. Pit bulls were selectively bred for "gameness," the ability to finish a fight. A truly gamedog will continue fighting "on stumps," two or more broken legs, with a cracked skull and worse. Excerpts from The Complete Gamedog, by Ed and Chris Faron, delve into more grisly details.10

The blood sport of dogfighting involves a contest between two dogs, primarily pit bulls, fighting each other in front of spectators for entertainment and gambling purposes. Other felonious activities, such as illegal drugs and firearm sales, often accompany dog fight matches. A single dog fight averages about an hour in length but can last two or more.11 A dog fight begins when a referee says, "Face your dogs," then says, "Let go." The fight match ends when one of the dogs will not or cannot continue.

The indictment of former NFL player Leshon Johnson in 2025 for running a large-scale dogfighting operation known as "Mal Kant Kennels," shows that dogfighting still proliferates. Authorities seized 190 pit bulls on his Oklahoma properties.12 Not long after, law enforcement in South Carolina seized 160 pit bulls in a multi-county dogfighting operation.13 From 2022 to 2023, federal authorities seized 425 pit bulls in separate multi-county dogfighting busts across the Midlands and Upstate South Carolina.14,15

There is no evidence that pit bulls selectively bred for dogfighting is slowing down in America or other parts of the world. "Dog fighters operate hidden in plain sight," and "the average person doesn’t realize how prevalent dogfighting still is," authorities say.16

In other states, law enforcement seized over 120 pit bulls in a dogfighting network in southern New Jersey operated by "Royal Bull Kennels."17 In central Florida, "Operation Pedigree," involving multiple agencies, seized 111 pit bulls from a dogfighting and drug trafficking ring.18 In Georgia, Vincent Lemark Burrell was found guilty of 93 counts of dogfighting and sentenced to 475 years in jail after authorities raided his Paulding County, Georgia compound in 2022 and seized over 100 fighting pit bulls.19, 20

Q: Why do I always read about pit bulls in the news?

When a pit bull attacks, the injury inflicted may be catastrophic. First responders, such as police officers and firefighters, understand this as do members of the media, who are quick to report these attacks. Ongoing social tension also keeps pit bulls in the news. The pit bull problem is now over 40 years old.21 In this time, most lawmakers have been "too afraid" to take the necessary actions to protect public health and safety. Due to this failure, horrific maulings continue to make headlines.

About half of all media reports regarding pit bulls involve police officers shooting dangerous pit bulls in the line of duty.22 Since the late 1970's pit bulls have been used extensively in criminal operations involving drug trafficking, illegal firearms, gang members and other violent offenders. The pit bull terrier is the breed of choice for criminals. This choice is directly linked to the pit bull's selectively bred traits of robust jaw strength, a punishing bite style, tenacity (gameness) and a high tolerance to pain.23

Q: Why do people say that pit bulls "don't let go?"

Through selective breeding, pit bulls have developed enormous jaw strength, as well as a ruinous "hold and shake" bite style, designed to inflict the maximum damage possible on their victims. This bite trait delivered winning results in the fighting pit. When the Colorado Supreme Court upheld the Denver pit bull ban in 2005, the high court set aside characteristics that pit bulls displayed when they attack that differ from all other dog breeds. One of these characteristics was their lethal bite style:

"[pit bulls] inflicted more serious wounds than other breeds. They tend to attack the deep muscles, to hold on, to shake, and to cause ripping of tissues. Pit bull attacks were compared to shark attacks."24,25 - Kory Nelson, Municipal Lawyer, 2005

Leading pit bull education websites, such as Pit Bull Rescue Central, encourage pit bull owners to be responsible and to always carry a "break stick" -- a tool used to pry open a pit bull's jaws -- in case their dog "accidentally" gets into a fight. These same websites also warn that using a break stick on any other dog breed may cause serious injury to the person.26 This is true because no other dog breed possesses the pit bull's tenacity combined with its destructive "hold and shake" bite style.

One of the most powerful examples of a pit bull "not letting go" occurred in an Ohio courtroom. During the Toledo, Ohio v. Paul Tellings trial -- where Tellings was convicted of violating the City of Toledo's pit bull ordinance -- Lucas County Dog Warden Tom Skeldon showed a videotape of a tranquilized pit bull hanging from a steel cable. The dog is essentially unconscious and still does not release its grip. At the time of the taping, the pit bull was being housed at the Lucas County Animal Shelter.27

Q: Do pit bulls bite more than other dog breeds?

Depending upon the community in which you live and the ratio of pit bulls within it, yes and no. But whether a pit bull bites more or less than another dog breed is not the relevant matter. The issue is the acute damage a pit bull inflicts when it does choose to bite. The pit bull's "hold and shake" bite style causes severe bone and muscle damage, often inflicting permanent and disfiguring injuries. Moreover, once a pit bull starts an attack, lethal firearm intervention may be the only way to stop the canine.

When analyzing dog bite statistics, it is important to understand what constitutes a bite. A single bite -- recorded and used in dog bite statistics -- is a bite that "breaks the skin." One bite by a poodle that leaves two puncture wounds is recorded the same way as a violent pit bull mauling, which can constitute hundreds of puncture wounds, extensive soft tissue loss and amputation. Despite the "quagmire" of dog bite statistics, pit bulls lead biting incidents across U.S. cities and counties.28

Q: Can a pit bull be correctly identified?

Yes, pit bulls are an identifiable dog breed. This is validated by a series of appellate court decisions starting in 1988. (For a breakdown of each decision see our special report: Pit Bulls Are Identifiable). Each appellate court concluded in its own variance that a "dog owner of ordinary intelligence" or a "layman" could identify a pit bull. Pit bull owners and animal welfare groups, however, still falsely claim the average person, and even professional shelter workers, cannot correctly identify a pit bull.

"Pit bull dogs possess unique and readily identifiable physical and behavioral traits which are capable of recognition both by dog owners of ordinary intelligence..."29 - Ohio v. Anderson, Supreme Court of Ohio, 1991

Nowhere do the high courts make any presumption of "expert" knowledge being necessary to identify a pit bull. Further, appellate courts in Ohio explained in 1989 and 1991 that "an ordinary person could easily refer to a dictionary, a dog buyer's guide or any dog book for guidance" and that "consistent and detailed descriptions of the pit bull dog may be found in canine guidebooks." These high court rulings occurred a decade before the invention of Google Search, and 35 years before ChatGPT.

Q: Why do pit bull owners often say, "My dog might lick you to death?"

To understand the experience of owning a negatively perceived dog, Tufts Center for Animals and Public Policy conducted a study on pit bull owners. Researchers found that owners of out-law dog breeds directly feel the stigma targeted at their breed and resort to various tactics to lessen it. One of the tactics included attempts to counterbalance the pit bull's menacing appearance and physical power with overwhelming "affectionate" behavior, such as: "My dog might lick you to death."

"As a way of counterbalancing the effect of this breed’s appearance and physical power, many respondents alluded to images and stories of their pit bulls' affection, which directly contradicted their intimidating reputation. Owners frequently focused on displays of affection as well as the breed’s sensitivity and attunement to people. One owner described the introduction between her pit bull and a wary friend who was concerned about the dog because she had young children:

...She came over here and sat down...and [my dog] got up on the couch and started kissing her and everything. And she’s like, 'Oh my God; well, I guess this is okay - the dog is just going to kiss my kids to death'!

Another owner, focusing on the contrast between his dog’s physical strength and her docile personality, explained, '[My pit bull] is a strong, powerful dog but, you know, she’d lick you to death.'"30 - Twining, et al., Society & Animals, 2000

Q: Why do people say, "Pit bulls are dog-aggressive not human-aggressive?"

Due to selective breeding for the purposes of dogfighting, pit bulls are highly dog-aggressive. This aggression is not limited to dogs; pit bulls frequently kill other companion pets and domesticated animals. Leading pit bull education websites warn pit bull owners to, "Never trust your pit bull not to fight." These same websites also state that pit bulls should never be left alone with another dog or animal.31 The practical and moral question is: Why is "pit bull dog aggression" tolerated at all?

Pit bull dog aggression is unacceptable for two reasons. In many cases, it leads to human aggression. A common scenario is the following: A loose pit bull attacks a leashed dog being walked by its owner. The owner gets seriously injured trying to stop the attack through redirected or direct aggression. Every year, one or more people suffer death due to pit bull dog aggression, including owners like Donald Gibson and Juan Ruiz, who died while trying to break up a fight between their pit bulls.

Secondly, far too many beloved companion pets and domesticated animals suffer a violent death by the powerful jaws of pit bull terriers each year. In some instances, these attacks involve pit bulls tearing through screen doors of private residential homes -- in a home invasion attack -- to kill the pet living inside.32 Owners of the pet may be forced to watch as their dog or cat is disemboweled by the pit bull and pray the vicious canine does not turn its attention on an innocent family member next.

Q: What is the best thing we can do for communities and pit bulls?

The best thing we can do for communities and pit bulls is to regulate pit bull ownership and pit bull breeding. Lowering the pit bull population will reduce the number of serious maulings and the euthanasia of pit bulls. Multiple animal organizations agree that pre-Covid, pit bulls comprised 40% to 60% of all shelter dog inventory, and pit bulls comprised 40% to 55% of all shelter dog euthanasia.33 This is true despite the fact that pit bulls only make up about 6% of the total U.S. dog population.34

Over 900 U.S. cities and nearly all privatized military housing -- the U.S. Army, U.S. Marine Corps and U.S. Air Force -- and many public housing authorities have breed restrictions. Such measures often include: mandatory spaying and neutering, liability insurance and strict containment requirements. The most progressive law, a pit bull ban ordinance, prohibits new pit bulls and new pit bull breeding. In just a few years time, these communities see a significant drop in pit bull bites and pit bull euthanasia.
