Some dogs are loving companions, some make wonderful playmates, while others are enthusiastic athletes. Likewise, some pooches are popular for their jaw strength and powerful bite force. These strongest dogs possess incredible strength and stamina.
Most of the dogs with the strongest bite force measurements usually also have a muscular build. Their endurance and power remain unmatched. Many of them have even earned a reputation as aggressive dogs.
However, no dog breed is inherently aggressive. Such behavior is usually triggered by various factors. For instance, when someone enters their territory or they encounter a potential threat. With proper training, you can overcome such behavior.
Here are 7 ultimate dog breeds with incredible jaw strength.
Ultimate Dog Breeds with Jaw Strength
1. Kangal

Roughly five times as powerful as the punch, Kangal dog’s jaws are the strongest among all breeds. Kangals were originally bred in Turkey to protect livestock from predators like wolves, bears, and boars. Their strongest bite force of 743 PSI added to their ability as protective dogs.
However, some people believe that the Kangal bite force is slightly overestimated. The shape of their jaw and head contributes to their incredible bite force. Having lots of strength, stamina, and endurance, a Kangal dog is all muscle.

Their intense bite force is capable of crushing bones and causing catastrophic injuries, which may require reconstructive surgeries or may even result in permanent disability. They have an intimidating appearance and are even banned in some countries due to their power and strength.
Thankfully, Kangals exhibit a gentle temperament and affectionate nature with their families. Proper training and early socialization are important to turn Kangals into well-behaved pups.
2. Cane Corso

Cane Corso is a large and muscular dog breed hailing from Italy. Having lots of strength and agility, these massive canines have been guarding property and families for several years. They have strong protective instincts and have been safeguarding livestock from predators as well.

Cane Corso has one of the strongest bite forces in the canine world, of around 700 PSI. They do not exhibit aggressive behavior in general, but when provoked, they can damage tendons and crush smaller bones with their powerful bite force.
Their name literally translates to “bodyguard dog,” and they are unwaveringly loyal to their owners. According to PetMD, their behavior largely depends on the training they receive an early age. With proper training, they make gentle and affectionate pets.
Cane Corso are confident pooches, extremely attentive to their surroundings. These quiet dogs are reserved towards strangers and do not want them in their territory.
3. Mastiff

Another dog breed with a strong bite force, Mastiffs are heavy boned canines of impressive strength. They are docile with their owners and have a protective nature. Mastiffs make formidable guardians and have an actual bite force of 556 PSI.

Their powerful jaws are capable of causing crushing injuries that can damage multiple tissue layers. After a Mastiff bite incident, you need immediate medical assistance.
However, when given consistent training and proper socialization, Mastiffs are patient and lovable companions, naturally wary of strangers.
Mastiffs are not naturally aggressive, but a lack of training can trigger such behaviors. For instance, a Mastiff attacked a blind little Havanese dog on a busy harborside, reported the BBC.
According to the American Kennel Club, Mastiffs learn quickly and are eager to please. They communicate a great deal with their eyes and are excellent at reading your expressions.
4. Tosa Inu

Tosa Inu or Japanese Mastiff was originally bred as a fighting dog. Having a bite force of around 556 PSI, the Tosa Inu is a large and powerful dog banned in many parts of the world. During an attack, they exert extraordinary pressure, which helps maintain the grip.

Pressure exerted causes extensive tissue damage and potentially fatal injuries. Tosa Inu is a patient, bold, and quiet dog having a tranquil nature if trained properly. They require extensive socialization to help them become accepting of visitors.
Due to their history as fighting dogs, they tend to be aggressive toward other dogs. They do well with the dogs of the opposite sex, so you can have a pair of this breed at your home. However, these pooches are not well-suited for multi-pet households.
Tosa Inu can be aggressive towards potential threats, but do not show aggression towards non-threatening humans.
5. Presa Canario

Perro de Presa Canario is a strong-willed and powerful dog breed from the Canary Islands. These massive yet docile dogs have a history as guard dogs. The strong dog bite force of 556 PSI is attributed to their strong jaws.

Presa Canarios are known to be aggressive and do not hesitate to attack in defense of their loved ones. Their intimidating looks, stamina, and endurance make them capable of protecting large properties. They are large in size, so they require plenty of space to roam and exercise.

6. Dogo Argentino

Dogo Argentino is a loyal, muscular, and athletic dog breed initially bred for big game hunting. They have a bite force of 500 PSI, allowing their strong jaws to tear through skin and muscle. Their strong bite strength causes severe lacerations and permanent nerve damage.

Being incredibly large in size and having immense power, the Dogo Argentino looks quite intimidating and can scare away people with its mere presence. Their stature and hardiness make them unsuitable for living in small spaces, so it’s best to give them ample outdoor space.

Rottweilers are known for their strength and their protective instincts. They have a bite force of 328 PSI, which may be less than other breeds on our list, but is strong enough to cause tissue damage. Rottweilers typically shake victims while attacking.

One of the most popular dog breeds, Rotties look muscular and intimidating and have earned a reputation as aggressive dogs.
However, this is not true. When trained properly, Rottweilers make incredibly loyal and affectionate family companions. But if you train the breed to attack, it can be the deadliest of all animals you could encounter in a public place.
