Top 10 Dog Breeds With the Strongest Verified Bite Forces

Not all dog bite force statistics are created equal. While many online sources throw around impressive PSI (pounds per square inch) figures, only a few breeds have had their bite strength properly measured and verified. This top 10 list ranks dog breeds – and one closely related hybrid – from the lowest to the highest confirmed bite strength. The list is based on documented data rather than myths and clearly shows that raw strength doesn’t necessarily equal danger. Instead, it reflects a dog’s physical capabilities.

Belgian Malinois – 195 PSI

The Belgian Malinois is known for its roles in police and military service, combining sharp intelligence with agility. Although its bite force of around 195 PSI isn’t the highest, it’s impressive for a dog of its size. What makes the Malinois truly effective is not its bite strength alone, but the precision and control it demonstrates through training.

Chow Chow – 220 PSI

The Chow Chow looks like a teddy bear but hides a surprisingly strong jaw. With a bite force of about 220 PSI, this ancient Chinese breed retains the strength from its history as a guard and hunting dog. Despite its cute appearance, the breed needs early socialization to ensure good behavior.

American Pit Bull Terrier – ~235 PSI

The Pit Bull Terrier has a reputation for being dangerous, but scientific measurements place its bite force at around 235 PSI – far from the strongest. This highlights that a dog’s behavior is more important than its physical strength, and that myths like “locking jaws” have no scientific basis.

German Shepherd – 238 PSI

The German Shepherd is widely used in law enforcement and military roles, with a bite force of approximately 238 PSI. It’s not just the physical strength that makes this breed effective – it’s also intelligence, obedience, and discipline. The breed is known for controlled and purposeful bites rather than brute force.

Doberman Pinscher – ~245 PSI

The Doberman has an estimated bite force of 245 PSI, reflecting its sleek but powerful build. Bred for protection, the breed is fast, responsive, and precise. While its bite strength is slightly below that of other large guard dogs, its speed and alertness make it highly effective in practice.

American Bulldog – 305 PSI

Compact and muscular, the American Bulldog has a bite force of about 305 PSI. Originally bred for farm work, the breed’s powerful jaws are still capable of impressive force. Despite its strength, it’s usually gentle with its family, and its full power is mostly seen in work situations or when provoked.

Siberian Husky – 320 PSI

Many are surprised to learn that the energetic and social Husky has a bite force of around 320 PSI. This strength likely comes from its wolf ancestry and its role as a resilient sled dog. Huskies are typically not aggressive, but their jaws are built to handle harsh environments and physical demands.

Rottweiler – 328 PSI

The Rottweiler is known for its massive strength and has a documented bite force of 328 PSI. Built for protection, it combines physical power with loyalty and calmness. When properly trained, Rottweilers show great restraint – even though they possess one of the strongest bites among domestic breeds.

Wolf-Dog Hybrid – ~400+ PSI

Wolf-dog hybrids – crosses between wolves and dogs – have some of the highest bite forces among canines, often measured at over 400 PSI. This power comes from their wolf lineage, where strong jaws are essential for hunting and survival. While not fully domesticated, their physical abilities show just how impactful genetics can be.

English Mastiff – 552 PSI

The English Mastiff tops the list with a confirmed bite force of 552 PSI – the highest documented among dog breeds. Its massive head and strong jaw muscles give it immense power. Despite that, Mastiffs are often gentle and calm. This breed perfectly illustrates that strength and a soft temperament can go hand in hand.
