The Dark History of Dog Fighting: From Ancient Blood Sport to Modern Crime
Dog fighting has a brutal history stretching back thousands of years, with roots in ancient civilizations like Egypt, Rome, and Greece. These societies staged vicious dog fights as public spectacles, pitting powerful breeds against each other—or even wild animals—for entertainment. By the Middle Ages, the blood sport had spread across Europe, where mastiff-type dogs were forced into bull-baiting and bear-baiting before transitioning to organized dog-on-dog combat. When European colonists brought their traditions to America in the 18th century, dog fighting became a popular gambling pastime, even among politicians and aristocrats. Breeds like the Pit Bull Terrier were selectively refined for strength, pain tolerance, and “gameness”—the relentless drive to fight to the death. Though outlawed in most Western nations by the 19th century, underground rings persisted, fueling the dark reputations of dog breeds with a history in dog fighting.
Despite global bans, dog fighting remains a grim reality in parts of Asia, Eastern Europe, and South America, where weak enforcement and cultural acceptance allow it to thrive. In countries like Japan and Russia, certain regions still permit Tosa Inu and Central Asian Shepherd fights under regulated (but controversial) conditions. Meanwhile, organized crime rings in the U.S. and Mexico continue to operate illegal pits, exploiting breeds like the American Pit Bull and Presa Canario. Animal welfare groups such as the ASPCA and Humane Society work tirelessly to rescue and rehabilitate victims, but the fight is far from over. While modern laws condemn this cruel and inhumane practice, the legacy of dog fighting lingers in the genetics of 7 dog breeds with a dark history in dog fighting—reminders of a brutal past that still haunts them today.

Cordoba Fighting Dog
Quick Stats:
- Height: 24-27 inches | Weight: 100-120 lbs | Origin: Córdoba, Argentina
- Original Role: Pit fighting to the death | Modern Role: Extinct
The Dark History:
The Cordoba Fighting Dog (Perro de Pelea Cordobés) was developed in late 19th-century Argentina specifically for organized dog fighting. Breeders crossed Mastiffs, Bulldogs, and Bull Terriers to create the ultimate pit fighter—a dog with crushing jaw strength, high pain tolerance, and zero hesitation. Unlike most fighting dogs that could be pulled apart, Cordobas would fight literally to the death, ignoring broken bones and blood loss. Gamblers prized them above all others.
Why They Went Extinct:
The same aggression that made them champions also made them impossible to breed. Males attacked females during mating. Females killed their own puppies. Littermates fought to the kill as soon as they could stand. By the 1920s, the breed had effectively vanished—too vicious to reproduce, too dangerous to keep.
From Pit to Present:
The Cordoba’s genetic line didn’t die; it was refined. In the 1920s, Dr. Antonio Nores Martínez took the last remaining Cordobas and crossed them with Great Danes, Pointers, and Pyrenean Mastiffs to create the Dogo Argentino—a big-game hunting dog that kept the Cordoba’s courage and strength but lost its uncontrollable aggression toward other dogs and people.
⚠️ Owner Alert:
The Cordoba is extinct. Its descendant, the Dogo Argentino, is banned in several countries and requires an experienced owner.

Tosa Inu – The Silent Sumo of Japan
Quick Stats:
Height: 24-27 inches | Weight: 130-200 lbs | Origin: Kochi, Japan
The Dark History:
The Tosa Inu was developed in the late 1800s by crossing native Shikoku fighting dogs with Western breeds—Mastiffs, Bulldogs, Great Danes, and even German Pointers. The goal was to create a larger, more powerful fighter for Japan’s traditional dog fighting culture, which dates back to the Edo period (1603–1868). Unlike Western blood sports, Tosa matches were silent, ritualized contests where dogs grappled to pin their opponent rather than bite and maul. Still, the fights were brutal, and losing dogs were often culled. Today, regulated Tosa matches still exist in a few Japanese prefectures under strict oversight, though the practice remains deeply controversial.
What Made Them Different:
The Tosa was bred for “heart” and stoic silence—barking during a fight was considered cowardly. This ritualized fighting culture produced a dog that could be calm and controlled outside the ring but deadly inside it.
From Pit to Present:
Modern breeders emphasize temperament above all. A well-socialized Tosa is calm, patient, and deeply loyal to its family. However, the breed’s fighting heritage has led to outright bans in the UK, Australia, Denmark, and several other countries. In Japan, the Tosa is honored as a national treasure—but one with a bloody past.
⚠️ Owner Alert:
Requires intense early socialization and an experienced handler. Never trust a Tosa unsupervised with strange dogs.

Staffordshire Bull Terrier
Quick Stats:
Height: 14-16 inches | Weight: 24-38 lbs | Origin: England
The Dark History:
The Staffordshire Bull Terrier was born in 19th-century England’s Black Country, where working-class miners and factory workers crossed Bulldogs (for raw power) with small, agile terriers (for tenacity and speed). The result was a compact, muscular dog built for bull-baiting—a bloody spectacle where dogs attacked tethered bulls. When bull-baiting was outlawed in 1835, desperate owners turned to illegal dogfighting pits. The “Staffy” became a favorite because it combined crushing bite force with a low center of gravity, making it hard to throw off balance.
The Unexpected Turn:
Here is where the story flips. When dogfighting was also banned, the same working-class families refused to give up their Staffies. Instead, they kept them as loyal companions. The breed’s fierce loyalty to humans—bred in because fighters needed to handle their dogs mid-battle—transformed into deep devotion to children. By the early 1900s, the Staffy had earned the nickname “the nanny dog” for its patience and protectiveness toward kids.
From Pit to Present:
Today, the Staffordshire Bull Terrier excels in obedience, agility, and therapy work. It is one of only two breeds (the other being the Bulldog) legally allowed to be shown in the UK with uncropped ears as part of its heritage. The Staffy’s journey from pit fighter to family pet is the most successful rehabilitation story in dog history.
⚠️ Owner Alert:
Banned in some regions due to misconceptions. With proper training and socialization, they are devoted, loving family dogs.

Bull Terrier
Quick Stats:
Height: 21-22 inches | Weight: 50-70 lbs | Origin: England
The Dark History:
The Bull Terrier was created in the early 1800s by crossing Bulldogs with terriers—and later adding Dalmatian and Spanish Pointer for a more refined appearance. Its original purpose was rat-baiting and bull-baiting, two brutal blood sports where dogs were thrown into pits with rats or tethered bulls. When the UK banned baiting in 1835, the Bull Terrier, like the Staffy, was dragged into illegal dogfighting rings. What set the Bull Terrier apart was its bizarre pain tolerance and “hard mouth”—a crushing, lockjaw grip that could break bones in seconds.
What Made Them Different:
Unlike the Staffy, the Bull Terrier was also bred for a distinctive egg-shaped head and triangular eyes—a look that made it instantly recognizable. But beneath that comical face was a dog capable of terrifying aggression. Early Bull Terriers were described by breed historians as “gladiators in a clown’s body.”
From Pit to Present:
Through selective breeding in the mid-20th century, the Bull Terrier’s aggressive tendencies were dramatically reduced. Today, the breed is known for its playful, exuberant, and sometimes goofy personality—earning the nickname “the kid in a dog suit.” The transformation from pit fighter to family clown is one of the most dramatic in any breed.
⚠️ Owner Alert:
Needs regular exercise and mental stimulation. Great with families but requires consistent training.
Fila Brasileiro
Quick Stats:
Height: 24-28 inches | Weight: 90-150 lbs | Origin: Brazil
The Dark History:
The Fila Brasileiro (Brazilian Mastiff) was developed during colonial times by crossing English Mastiffs, Bloodhounds, and Bulldogs. Its original job was brutal but practical: tracking down escaped slaves on massive plantations and hunting jaguars in the jungle. The Fila’s unique trait was its “ojeriza”—a deep, instinctual wariness of strangers that made it attack anyone not part of its family. This same aggression was later exploited in underground dogfighting rings, where the Fila’s endurance, powerful grip, and refusal to release a bite made it a feared competitor.
What Made Them Different:
Unlike purpose-built fighting breeds like the Cordoba, the Fila was never bred solely for pit work. Its fighting career was secondary to its roles as a plantation guardian and big-game hunter. This meant the breed retained working intelligence and loyalty—traits that helped it survive after dogfighting declined.
From Pit to Present:
Today, the Fila is a national symbol of Brazil, prized as a livestock guardian and property protector. However, its powerful temperament and “ojeriza” have led to bans in the UK, Australia, and several other countries. The breed is not for everyone—but in the right hands, it is a fiercely loyal and intelligent working dog.
⚠️ Owner Alert:
Requires experienced handling and early socialization. Banned in multiple countries. Not for first-time owners.

Presa Canario
Quick Stats:
Height: 22-26 inches | Weight: 85-140 lbs | Origin: Canary Islands, Spain
The Dark History:
The Presa Canario (Canary Mastiff) was originally a working farm dog—used to herd cattle, guard property, and kill feral dogs that threatened livestock. It was developed from the native Bardino Majero crossed with imported English Mastiffs and Bulldogs. For centuries, the Presa was respected as a capable guardian, not a pit fighter. That changed in the mid-20th century when Spain’s rural economy collapsed. Unemployed workers turned their Presas on each other in illegal gambling rings, and the breed’s strength, courage, and natural suspicion of strangers made it a star in underground dogfighting.
What Made Them Different:
Unlike breeds bred specifically for fighting, the Presa’s aggression was always “contextual”—intense toward threats but neutral toward its family. After dogfighting declined, the breed did not become dangerously unstable. It simply returned to its original role as a guardian.
From Pit to Present:
Dedicated breeders in the 1970s and 80s worked to reclaim the Presa Canario’s original purpose. Today, the breed is known for its calm confidence, intelligence, and fierce loyalty. It excels in protection sports and as a family guardian—but remains restricted in some countries like Australia and New Zealand due to its power and protective instincts.
⚠️ Owner Alert:
Requires strong leadership and early socialization. Not for apartment living or novice owners.
Bully Kutta
Quick Stats:
Height: 30-35 inches | Weight: 150-200 lbs | Origin: Indian subcontinent
The Dark History:
The Bully Kutta (Pakistani Mastiff) is an ancient breed, not a modern creation. For centuries, it served as a war dog, big-game hunter, and estate guardian across the Indian subcontinent. Its job was to take down wolves, leopards, and even bears—often fighting multiple predators at once. The breed’s name translates to “heavily wrinkled dog” in Urdu, referring to its loose, thick skin, which made it harder for teeth to penetrate during combat. This same ferocity and pain tolerance were later exploited in underground dogfighting rings, where the Bully Kutta’s sheer size (up to 200 pounds) made it nearly unbeatable against smaller breeds.
What Made Them Different:
The Bully Kutta was never a “man-made” fighting breed like the Cordoba. Its combat abilities evolved naturally over hundreds of years of survival and work. This means the breed retains intelligence, loyalty, and a strong bond with its handler—traits often lost in purpose-built fighting dogs.
From Pit to Present:
In rural Pakistan and India, the Bully Kutta remains revered as an elite guardian and hunting dog, not a pit fighter. Ethical breeders are working to distance the breed from its brutal associations, promoting its noble heritage and condemning exploitation. However, the breed’s massive size and power mean it will never be a mainstream family pet.
⚠️ Owner Alert:
Demands experienced handling, space, and a confident owner. Not for apartments or first-time dog owners.
The “Reputation vs. Reality” Breeds: Informal Fights, But Never Fighting Dogs
The following three breeds are often mistaken for “fighting dogs” due to their size, power, or protective instincts. While individual dogs may have been used in informal, one-off fights—village disputes, rural challenges, or isolated incidents—these breeds were never systematically developed, selectively bred, or legacy-defined by organized dog fighting. Their true histories lie elsewhere.
Cane Corso
Quick Stats:
Height: 23-27 inches | Weight: 90-120 lbs | Origin: Italy
The Reputation:
Because of its size, muscular build, and intimidating stare, the Cane Corso is often lumped in with “fighting breeds.” Some online forums and outdated breed guides even list it alongside Pit Bulls and Tosa Inus. This is incorrect.
The Reality:
The Cane Corso descends from ancient Roman war dogs, but its historical role was never pit fighting. For centuries, it worked as a farm guardian, cattle drover, and wild boar hunter across rural Italy. Its job was to protect property from intruders and predators—not to fight other dogs for sport. Any fights that occurred were incidental: a Corso might clash with a wolf or a stray dog trespassing on its farm. But organized, systematic dog fighting was never part of the breed’s development or legacy.
From Then to Now:
Today, the Cane Corso is prized as a versatile working dog and loyal family guardian. Ethical breeders emphasize stable temperament and trainability. The breed is restricted in some countries (like Romania and Malta) due to its size and protective nature—not because of any significant fighting history.
⚠️ Owner Alert:
Requires firm training and early socialization. Excellent guardian but needs a confident, experienced owner.
Chinese Shar-Pei
Quick Stats:
Height: 18-20 inches | Weight: 45-60 lbs | Origin: China
The Reputation:
The Shar-Pei’s loose, wrinkly skin and scowling face have led many to assume it was a fighting breed. The logic goes: loose skin makes it harder for an opponent to get a grip, so it must have been bred for pits. This is a misunderstanding.
The Reality:
The Shar-Pei’s primary roles in ancient China were hunting, herding, and guarding farms and monasteries. Its loose skin did help in fights—but those fights were with wild boars and predators, not other dogs. There is evidence of occasional, informal village dogfights in rural China, where farmers might pit their dogs against each other for entertainment. However, the Shar-Pei was never systematically bred for organized dog fighting. It lacked the stamina, “gameness,” and relentless drive of true fighting breeds. By the time the breed was nearly extinct after the Chinese Communist Revolution, its identity was as a working farm dog, not a pit fighter.
From Then to Now:
Modern Shar-Peis have been selectively bred for companionship and show. Aggression is now considered a breed fault. The loose skin remains—but as a charming quirk, not a fighting adaptation.
⚠️ Owner Alert:
Loyal and calm but can be stubborn. Early socialization is important. Makes an excellent family pet when properly raised.

Central Asian Shepherd
Quick Stats:
Height: 25-28 inches | Weight: 110-180 lbs | Origin: Central Asia
The Reputation:
The Central Asian Shepherd (also called the Alabai) is massive, fearless, and protective. Because of this, outsiders sometimes assume it has a fighting background. In some regions, travelers have witnessed dogs squaring off and assumed it was “dogfighting.”
The Reality:
The Alabai is one of the oldest known livestock guardian breeds, with a history spanning over 4,000 years. Its job was to protect flocks of sheep from wolves, bears, and human predators—often fighting wild animals to the death. This is wolf fighting, not dog fighting. In some rural Central Asian cultures, there are traditional “dominance tests” where dogs are allowed to establish pack hierarchy through ritualized scuffles. These are not organized blood sports; they are brief, often non-lethal displays that end when one dog submits. The Alabai was never selectively bred for “gameness” against other dogs. Its loyalty, intelligence, and protective instincts are directed at threats—not at random dogs.
From Then to Now:
Today, the Central Asian Shepherd remains a respected working dog across Kazakhstan, Turkmenistan, and Uzbekistan. It is used as a military and prison guard dog in some regions. Its fighting reputation is a myth born from confusing “livestock guardian fighting wolves” with “pit dog fighting other dogs.”
⚠️ Owner Alert:
Independent, strong-willed, and dominant. Requires experienced handling and a firm leader. Not for first-time owners.
Why This Distinction Matters
Labeling a breed as a “fighting dog” has real consequences. Bans, housing restrictions, insurance denials, and public fear often follow. The Cane Corso, Shar-Pei, and Central Asian Shepherd have already been restricted or banned in some countries—not because of any actual fighting legacy, but because of a misunderstood reputation.
Breed history is not about how a dog looks. It is about what the dog was bred to do for generations. These three were never bred to fight other dogs. That is not their story. That is not their legacy.
FAQs About Dog Fighting Breeds
What is dog fighting and why is it illegal?
Dog fighting is an illegal and brutal blood sport in which dogs are trained and forced to fight against each other. The practice is banned in many countries around the world due to the severe physical harm and psychological trauma that dogs suffer during these fights. Additionally, dog fighting often involves illegal gambling, cruelty to animals, and other criminal activities.
Why are these breeds still popular today despite their history with dog fighting?
Despite the negative reputation that dog fighting breeds carry, many people still find them attractive for their strength, courage, and loyalty. These breeds are often prized as family pets, working dogs, or even therapy animals. It is important to remember that while these breeds may have a history with dog fighting, they are not inherently aggressive and can make wonderful companions with proper socialization and training.
Is it safe to own a “dog fighting” breed?
Yes, it is safe to own a dog fighting breed as long as they are properly socialized and trained. However, it is important to remember that these breeds are often powerful and confident, and may require a more experienced owner to handle them. It is also important to find a reputable breeder who does not perpetuate the cycle of violence and promotes responsible ownership.
Are there any legitimate reasons for breeding and training dogs to fight?
No. Zero. None.
Dog fighting is a felony in all 50 US states and in most developed countries. There is no cultural, traditional, or sporting justification for forcing dogs to fight to the death. Even “ritualized” fights (like some Tosa matches in Japan) are controversial and increasingly condemned by modern animal welfare standards. Breeding dogs for fighting is animal cruelty, plain and simple.
Are Tosa Inu still used for dog fighting in Japan today?
Yes, but not how you think.
Unlike Western dogfighting, traditional Tosa matches are ritualized, silent contests where dogs grapple to pin their opponent rather than bite and maul. These fights still occur in a few Japanese prefectures (like Kochi) under strict regulation. However, the practice remains deeply controversial. The Tosa Inu is banned in the UK, Australia, Denmark, and several other countries due to its fighting heritage.
Why is the Cane Corso banned in some countries if it wasn’t a fighting breed?
Because bans are based on looks and capability, not history.
The Cane Corso is restricted in countries like Romania, Malta, and the Cayman Islands due to its size, power, and protective instincts—not because of any significant fighting history. As covered in our “Reputation vs. Reality” section, the Corso was a farm guardian and wild boar hunter, not a pit fighter. Unfortunately, breed-specific legislation (BSL) often targets any large, muscular molosser breed regardless of its actual historical purpose.
What happened to the Cordoba Fighting Dog? Why did it go extinct?
The Cordoba Fighting Dog went extinct because it was too aggressive to breed.
Males attacked females during mating. Females killed their own puppies. Littermates fought to the death as soon as they could stand. The very traits that made the Cordoba a champion pit fighter—relentless aggression, zero self-preservation, fight-to-the-death mentality—made it impossible to sustain a breeding population. By the 1920s, the breed was functionally extinct. Its genetic legacy lives on through the Dogo Argentino.
Dog Fighting Breeds – Final Thoughts
The dark history of dog fighting matters.
It is not ancient history. It is a cruel and abusive practice that still happens today—in underground rings, in rural areas with weak enforcement, and in countries where cultural acceptance has not caught up to the law.
The dogs are victims, not villains.
Breeds developed for fighting did not choose their purpose. They were manipulated by unscrupulous people who exploited their strength, pain tolerance, and loyalty for profit and entertainment. A Staffordshire Bull Terrier is not “born bad.” It was born into a legacy written by humans.
Three things we can do right now:
- Educate, don’t discriminate. Learn the difference between true fighting breeds (Cordoba, Tosa, Staffy, Bull Terrier, Fila, Presa, Bully Kutta) and breeds with an unfair reputation (Cane Corso, Shar-Pei, Central Asian Shepherd). Bans based on looks hurt innocent dogs.
- Support the rescuers. Organizations like the ASPCA and Humane Society work tirelessly to rescue and rehabilitate victims of dogfighting rings. They need donations, fosters, and advocates.
- Advocate for stricter laws. Dogfighting remains a felony in many places but is still under-enforced. Stronger penalties, better enforcement, and community reporting save lives.
A final reminder:
A dog’s past does not dictate its future. The Staffordshire Bull Terrier went from pit fighter to “nanny dog.” The Bull Terrier went from gladiator to family clown. The Dogo Argentino was rebuilt from the extinct Cordoba into a stable working breed.
Change is possible. But it starts with honesty about the past and action in the present.
Together, we can create a future where all dogs are treated with compassion and respect—free from the horrors of dogfighting and other forms of animal abuse.
