What Dog Has the Strongest Bite Force? Complete Ranking & PSI Chart
Key Takeaways
- The Kangal has the strongest bite force among dogs, measuring around 743 pounds per square inch.
- Bite force comes from jaw muscles, skull shape, and body size working together.
- Larger guardian breeds generally produce higher PSI than smaller companion breeds.
- A dog bite force chart ranks over 20 breeds from the Kangal to the Golden Retriever.
- Bite force alone does not determine how dangerous a dog will behave.
A dog attack can turn frightening fast, and the breed involved often decides how severe the injuries become. O’Brien & Ford works with dog bite victims across Buffalo, New York, and one question comes up again and again once the shock wears off: what dog has the strongest bite force? The Kangal holds that record, generating roughly 743 pounds of pressure per square inch.
A Buffalo Dog Bite Lawyer can explain how that bite force connects to the severity of an injury claim, and this guide breaks down the rankings and what they mean for safety.

Understanding Dog Bite Force
How Is Dog Bite Force Measured?
Bite force reflects how well a dog’s jaw muscles, skull, and teeth work together. Researchers measure it using pressure transducers, electrical stimulation of the jaw muscles under anesthesia, or mathematical models built from skull measurements. A veterinary review published in Frontiers in Veterinary Science notes that these methods produce varying results depending on the animal’s willingness to bite down fully.
What Is Bite Force (PSI)?
PSI stands for pounds per square inch, the pressure a bite exerts on a single point of contact. A higher number means more crushing force. The average human bite measures around 162 PSI, and a bear’s bite reaches roughly 1,200 PSI, according to a bite force comparison from a service dog training resource. Dogs fall across a wide range between those two figures.
Factors That Influence Bite Strength
Jaw anatomy and skull structure matter most, since a broader skull and longer jaw lever create stronger muscle attachment points. Muscle mass and body size add to that base, which is why giant breeds tend to rank higher than small ones. A breed’s original working role matters too, and it explains much of what dog has the strongest bite force across different breeds. Dogs bred to guard livestock against large predators, like the Kangal, developed jaw strength that companion breeds never needed.
Dog Bite Force Comparison Chart
The chart below ranks 21 breeds by commonly cited estimated bite force, from the powerful Kangal down to the considerably gentler Golden Retriever. These figures reflect frequently referenced estimates rather than one controlled study, since testing methods vary across sources.
| Dog Breed | Bite Force |
| Kangal | 743 PSI |
| American Bandogge | 730 PSI |
| Cane Corso | 700 PSI |
| Tosa Inu | 556 PSI |
| Dogue de Bordeaux | 555 PSI |
| English Mastiff | 552 PSI |
| Presa Canario | 540 PSI |
| Dogo Argentino | 500 PSI |
| Wolfdog | 406 PSI |
| Akita | 400 PSI |
| Leonberger | 399 PSI |
| Rottweiler | 328 PSI |
| Siberian Husky | 320 PSI |
| Doberman | 305 PSI |
| Bulldog | 298 PSI |
| Great Dane | 260 PSI |
| German Shepherd | 238 PSI |
| Pit Bull | 235 PSI |
| Belgian Malinois | 195 PSI |
| Chow Chow | 190 PSI |
| Golden Retriever | 180 PSI |
Even breeds near the bottom of this chart can still cause a serious injury under the wrong circumstances, which is part of why the next question matters just as much as the ranking.
Does Bite Force Determine How Dangerous a Dog Is?
Bite force alone does not determine how dangerous a dog is. What dog has the strongest bite force and which dog is most likely to bite are two different questions entirely, and treating them as the same one leads to flawed assumptions about safety.
Several factors shape whether a strong-jawed breed becomes a genuine risk:
- Temperament: Individual personality varies within every breed, and a calm dog with a powerful bite can pose less risk than an anxious dog with a weaker one.
- Training: Consistent obedience work and impulse control reduce the odds that a dog responds to stress or fear with its teeth.
- Socialization: Early, positive exposure to people, animals, and new situations shapes how a dog reacts to unfamiliar situations later in life.
- Owner Responsibility: Secure fencing, supervised interactions, and prompt correction of warning signs fall on the owner, not on the dog’s genetics.
When any dog, regardless of jaw strength, injures someone through an owner’s negligence, our attorneys help Buffalo victims determine whether that negligence, not the animal’s bite force, is what actually caused the harm.
