It’s funny how some dogs look like living teddy bears, yet nature equipped them with jaws strong enough to snap through bone.
When researchers tested bite strength, the results were downright surprising: several well-known breeds actually clamp down harder than a lion.
Still, the story isn’t about fear — it’s about understanding these animals, and the simple truth that a dog’s behaviour depends on the people raising it.
What “Bite Force” Really Tells Us
Scientists talk about bite force in pounds per square inch, or psi.
It’s just a measure of how much pressure a set of jaws can put on one tiny point.
For comparison, a person manages around 80 kilograms per square centimetre — enough to break a walnut, but nowhere near the power levels some dogs produce.
Bigger dogs usually pack more jaw power thanks to stronger muscles, but there are a few mid-sized surprises that hit much harder than you’d guess.
These “bite force heavyweights” make up the PETBOOK list of eleven breeds with the strongest measured jaw pressure.
#11 and #10: A Controlled Worker and a Fluffy Powerhouse
Belgian Malinois — ~200 psi
Landing in eleventh place, this energetic working dog is famous in police and military units.
Fast, sharp, and eager to learn, the Malinois has a bite that’s strong but extremely manageable thanks to its trainability.
Chow Chow — ~220 psi
One step up is the Chow Chow, the iconic “lion dog” of China.
Behind its plush fur and serious expression is a bite force that surprises many owners.
Handled correctly, this independent breed becomes a deeply loyal companion.
#9 to #7: Strong Jaws, Soft Personalities
Three breeds sit closely together in the 224–238 psi range:
Dutch Shepherd — ~224 psi
Agile, attentive, family-friendly, and great with kids — this breed mixes working talent with a warm temperament.
American Pit Bull — ~235 psi
Muscular and playful, the Pit Bull is far gentler than its reputation suggests.
With responsible ownership, it’s one of the most affectionate dogs you can meet.
German Shepherd — ~238 psi
A global favourite for service work and home life, the GSD blends endurance, intelligence, and reliability.
If these dogs prove anything, it’s that jaw strength doesn’t equal aggression.
The real difference comes from training, social experiences, and the structure the owner provides.
#6 to #4: Heritage Breeds With Serious Power
American Bulldog — ~305 psi
At sixth place, the American Bulldog’s bite force mirrors that of a leopard.
Confident and sturdy, it thrives with owners who can set boundaries and keep it active.
Rottweiler — ~328 psi
Long associated with guarding roles, Rottweilers balance their strength with striking loyalty.
A well-raised Rottie is steady, affectionate, and deeply protective without being reactive.
Mastiffs — ~556 psi
Then come the giants. Despite their imposing size and jaw power, Mastiffs are usually gentle, thoughtful dogs when socialized early.
#3 and #2: Two Contrasts and One Giant
Doberman — ~600 psi
Sleek and speed-oriented, the Doberman is extremely alert and tuned in to its owner’s emotions.
Its bite force puts it among the strongest.
Caucasian Shepherd — ~600 psi
Sharing the same ranking but with a completely different build, this mountain guardian takes its duty seriously.
These dogs demand experienced handlers who understand their strong instincts.
Cane Corso — ~700 psi
In second place stands the Cane Corso. Muscled, majestic, and impressively powerful, it’s usually a calm, affectionate family dog when raised with clear rules and steady guidance.
#1: The Kangal, A True Living Legend
At the top of the list is the Kangal, a breed known in Turkey as a fearless protector of livestock.
With a jaw pressure of around 743 psi, its bite force surpasses that of a lion.
Historically used to defend flocks from wolves and even bears, the Kangal remains remarkably composed and loyal when responsibly trained.
Its presence alone is enough to deter threats.
