When it comes to canine strength, jaw power is one impressive feature that sets certain breeds apart.
These dogs have developed incredible bite force through generations of breeding for specific tasks like hunting, guarding, or working.
Understanding which breeds possess exceptional jaw strength isn’t just fascinating – it’s important information for potential owners, trainers, and anyone who works with dogs professionally.
1. Kangal: The Guardian With Earth-Shattering Bite Force
Topping the charts with a bite force of 743 PSI, this Turkish guardian breed outranks all domestic dogs in jaw power. Developed to protect livestock from predators like wolves and bears, Kangals needed extraordinary strength.
Their massive heads house powerful jaw muscles that deliver incredible force when needed. Despite this tremendous power, well-socialized Kangals are known for their gentle nature with family members.

3. Cane Corso: Italy’s Ancient Powerhouse
Dating back to ancient Rome, these Italian mastiffs were war dogs with jaw strength measuring approximately 700 PSI. Their name derives from “cohors,” meaning “guardian” or “protector.”
A Cane Corso’s broad skull houses massive jaw muscles that can exert tremendous pressure. While historically used for hunting wild boar and cattle driving, today they serve as loyal family guardians who can effortlessly crush large bones.
4. Dogo Argentino: The White Hunter
Created specifically for big-game hunting in Argentina, these striking white dogs boast jaw strength around 500 PSI. Their creator, Antonio Nores Martínez, developed them to hunt wild boar and puma in the 1920s.

5. Dogo Canario: The Canary Islands’ Cattle Driver
Hailing from Spain’s Canary Islands, these formidable dogs deliver approximately 540 PSI of bite force. Historically used for cattle driving and as catch dogs, their jaw strength served crucial working purposes.
Their broad, square head houses impressive jaw muscles that lock with tremendous force. Once on the brink of extinction, the breed was revived in the 1970s, preserving their distinctive strength while developing more balanced temperaments.
6. American Bulldog: The Versatile Farmhand
Farm life shaped these powerful dogs, whose bite force reaches approximately 305 PSI. Unlike their English cousins, American Bulldogs maintained their athletic working abilities rather than being bred primarily for appearance.
Their wide jaws and strong neck muscles made them excellent catch dogs for farmers. The breed nearly disappeared after World War II but was saved by a few dedicated breeders who preserved their impressive strength and working abilities.
7. Rottweiler: The Roman Drover With Crushing Power
Following Roman legions across Europe, Rottweilers drove cattle and protected camps with their impressive 328 PSI bite force. The breed nearly vanished until rediscovered as police and military dogs in the early 1900s.
Their broad head and powerful neck support exceptional jaw strength. While intimidating statistics circulate about their bite, properly trained Rottweilers demonstrate remarkable control over their powerful jaws, using force only when necessary.
8. American Pit Bull Terrier: The Misunderstood Powerhouse
Measuring around 235 PSI in bite force, these athletic dogs possess strength disproportionate to their medium size. Originally bred for bull-baiting and later for farm work, their powerful jaws served multiple purposes.
Their head structure features prominent jaw muscles and a wide skull. Despite media portrayal, well-bred Pit Bulls demonstrate remarkable bite inhibition and control, using their strength selectively—a testament to their intelligence and trainability.

12. Tosa Inu: Japan’s Canine Sumo Wrestler
Developed in Japan’s Tosa region as fighting dogs, these massive canines deliver approximately 556 PSI of bite force. Their creation involved crossing native Shikoku fighting dogs with various Western breeds to increase size and power.
Strict breeding regulations maintain their impressive physical capabilities. In their homeland, they’re called “sumo wrestlers of the dog world,” reflecting both their size and the cultural significance attached to their controlled power.
13. Boerboel: South Africa’s Farm Protector
Developed by Dutch settlers in South Africa, Boerboels use their approximate 450 PSI bite force to protect remote farms from predators. Their name translates to “farmer’s dog,” reflecting their primary purpose.
