The 10 Dog Breeds With the Strongest Bite Forces, Ranked

Dogs are beloved companions, yet many breeds possess a formidable bite. While the average canine exerts about 235 psi, certain breeds far exceed this figure. Below is a definitive ranking of the ten breeds that deliver the most powerful bites, based on peer‑reviewed research and breed-specific data.

What Determines a Dog’s Bite Force?

Like all animals, a dog’s bite strength correlates strongly with body size. However, a 2020 study published in the Journal of Experimental Biology revealed that jaw morphology also plays a critical role. Large, short‑snouted (brachycephalic) dogs—such as Rottweilers, Pit Bulls, and Bulldogs—typically exhibit higher bite forces than their long‑snouted counterparts, a trait that historically aligns with breeds used for protection and defense.

The study noted significant individual variation within breeds; for instance, Beagle specimens recorded bite forces ranging from 559 N to 1,018 N on a single tooth.

10. Central Asian Shepherd Dog – 500 psi

The Central Asian Shepherd Dog, one of the world’s oldest breeds, evolved through natural selection rather than targeted breeding. Standing 27.5 in (69.9 cm) tall and weighing 110 lb (49.9 kg), these dogs served nomadic tribes as guardians of people and livestock.

9. Perro de Presa Canario – 540 psi

As a member of the mollosser group—which includes the English Mastiff and Cane Corso—this short‑snouted breed was bred for guarding livestock and property. Historically used in dog fights, its robust build delivers a powerful bite.

8. Tibetan Mastiff – 550 psi

With males reaching 26 in (66 cm) at the shoulder and weighing up to 150 lb (68 kg), the Tibetan Mastiff’s size and dense mane belie its role as a mountain guardian, protecting herds from wolves and snow leopards.

7. Caucasian Shepherd Dog – 550 psi

Measuring up to 30 in (76.2 cm) and weighing up to 170 lb (77.1 kg), this Eastern European shepherd has protected livestock and humans from predators such as coyotes and wolves for centuries.

6. English Mastiff – 552 psi

The English Mastiff, the largest of the mastiff breeds, stands at least 30 in (76.2 cm) tall and can weigh up to 230 lb (104 kg). With origins dating back to 55 BCE, this “gentle giant” has served as a war dog, hunter, and guard.

5. Black Russian Terrier – 556 psi

Despite its name, the Black Russian Terrier is a large working dog that can reach 30 in (76.2 cm) at the shoulder and weigh 130 lb (60 kg). Developed in post‑war Russia, it combines the strength of Rottweilers, Giant Schnauzers, Airedale Terriers, and Newfoundlands.

4. Tosa – 556 psi

The Tosa Inu, a hybrid of Shikoku, Bulldogs, Mastiffs, German Pointers, and Great Danes, stands 21.5–23.5 in (54.6 cm) tall and can weigh up to 200 lb (90.7 kg). Originally bred for fighting, it has a short, powerful muzzle.

3. Dogue de Bordeaux – 556 psi

Also known as the French Mastiff, this breed reaches 27 in (68.6 cm) and weighs 110 lb (49.9 kg). Its proportionally largest head among dogs gives it a very large mouth and consequently a strong bite.

2. Cane Corso – 700 psi

Named “bodyguard dog” in Italian, the Cane Corso stands 28 in (71.1 cm) tall and typically weighs over 100 lb (45.4 kg). Its thick, waterproof coat and powerful jaw make it an exceptional guard dog.

1. Anatolian Shepherd Dog – 743 psi

Developed in Turkey to protect flocks against wolves, the Anatolian Shepherd reaches 29 in (73.7 cm) and can weigh up to 150 lb (68 kg). Its sheer size and evolved guarding instincts give it the highest bite force among domestic breeds.

Strongest Dog Bite FAQ

Which dog breed has the strongest bite force?

The Anatolian Shepherd Dog, with a bite force of 743 psi, tops the list.

How do scientists measure bite strength?

Researchers use a bite force transducer—an instrument that quantifies the force between two teeth—and biomechanical models to estimate bite strength across species.

What is the American Bulldog bite force?

Estimated at 305 psi, the American Bulldog’s bite is stronger than the German Shepherd (291 psi) but less than the American Pit Bull Terrier (328 psi).
