While many dogs today are known for their affectionate nature and companionship, several breeds have a darker past rooted in bloodsports and combat. These breeds were selectively bred for their strength, endurance, and aggression to excel in fighting rings. Understanding their origins helps provide important insight into their behavior, training needs, and responsibilities as owners. Here are ten dog breeds that were originally bred for fighting.
American Pit Bull Terrier

The American Pit Bull Terrier was developed in the 19th century by crossing bulldogs with terriers, aiming to combine strength with agility. These dogs were bred specifically for dog fighting and were prized for their tenacity and pain tolerance. Despite their reputation, with proper training and socialization, Pit Bulls can be loyal and affectionate pets.
American Bulldog

Originating from the Old English Bulldog, the American Bulldog’s ancestors were used in bull-baiting, a cruel bloodsport. When these practices were banned, the breed found new purpose on American farms but retained its powerful build and fearless nature. Their fighting background has influenced their protective and dominant temperament.
Bull Terrier

Created by mixing Bulldogs with various terriers, the Bull Terrier was designed for fighting in 19th-century England. Its distinctive egg-shaped head and muscular frame made it a formidable opponent. While they’ve since transitioned into playful, high-energy pets, their strength and determination are reminders of their original purpose.
Dogo Argentino

The Dogo Argentino was developed in Argentina in the 1920s by crossing several breeds, including the Cordoba Fighting Dog, to hunt big game and engage in combat. Bred to be fearless and powerful, the Dogo can be a devoted and protective companion with consistent training and firm leadership.
Tosa Inu

Bred in Japan for the sole purpose of dog fighting, the Tosa Inu is still used for this purpose in parts of Japan where the practice remains legal. This breed was developed by mixing native Japanese dogs with powerful Western breeds like Mastiffs and Bulldogs, resulting in a strong, stoic fighter.
Staffordshire Bull Terrier

Staffordshire Bull Terriers were developed in England for bull-baiting and later dog fighting. They were created by crossing Bulldogs with smaller terriers, producing a compact but strong dog with incredible tenacity. Today, they are often affectionate family pets, particularly in the UK, but still require early socialization.
Cane Corso

While the Cane Corso was primarily bred for guarding and hunting, its lineage traces back to Roman war dogs that were sometimes used in fighting pits. Their size, strength, and protective instincts have made them both guardians and, at times, combatants. Responsible ownership is essential for this powerful breed.
Presa Canario

Originating in the Canary Islands, the Presa Canario was historically used for guarding livestock—and fighting. These dogs have powerful jaws and a commanding presence. Though calm and loyal with proper training, their past as fighting dogs has influenced their assertive and dominant nature.
Akita Inu

The Akita Inu was bred in Japan for hunting large game and guarding, and was occasionally used in dog fighting. Known for their loyalty and independence, Akitas can be territorial and dominant. Their strength and reserved nature are traits that stem from their fighting and hunting history.
Shar Pei

The Shar Pei, recognized for its deeply wrinkled skin, was once a fighting dog in ancient China. The breed’s loose skin made it harder for opponents to get a firm grip during fights. Though now often quiet and calm, the Shar Pei’s wariness of strangers reflects its combative past.
