Several factors determine the strength of a dog's bite. Some dogs can cause more damage than others because of their size and the power of their jaws.
Victims of dog bites often require both medical and legal attention to get compensated for their injuries. Insurance companies tend to consider the breed of dog when assessing the owner's liability.
As a personal injury attorney, I have seen many cases of dog bites, and knowing which dogs can do the most damage is essential.
- Dog breeds with stronger bites can cause more damage and are, therefore, more dangerous.
- We use PSI to measure the pressure exerted by a dog's bite to determine the strongest bite force amongst all dog breeds.
- There are several things to consider when calculating the average dog bite force.
What Is PSI for Dogs?
PSI for dogs is a measurement of the dog's bite force or the amount of pressure a dog can exert when it bites .
To find out a dog bite force, we measure the amount of pressure they exerted by using pounds per square inch or PSI.
Though there are a few different ways to calculate it, the most common way is for us to use a formula that considers their weight and jaw size.

How Do You Measure the Strength of a Dog Bite?
You can measure the strength of a dog bite by using a formula that includes the dog's weight and jaw size. The most precise way to measure a dog's bite force is using a "bite sleeve."
It's a unique device that simulates being bitten and can therefore describe the pressure a dog exerts in great detail.
To calculate the average dog's bite force, you must consider the following:
- The dog's weight
- The size of the jaw of the dog
- The type of surface the dog bites
- The angle of the dog's bite
- The surface's hardness
- The dog breed

Dog Breeds with the Strongest Bite Force
It is difficult to determine which dog breed has the strongest bite force, as a few breeds boast strength and power.
Based on my research and previous cases, there are various dog breeds with the strongest bites below.
Belgian Malinois (195 PSI)
Belgian Malinois dogs have a history of being used in the military and law enforcement due to their unrelenting strength, power, and agility. They are known as some of the most versatile breeds of dogs. The Belgian Malinois is one of the strongest dog breeds and has a powerful bite.
Chow Chow (220 PSI)
Because they were originally bred as guard dogs, Chow Chows have a strong bite of 220 pounds per square inch from their jaw straight down.
Still, the Chow-Chow is a widely adopted breed. They typically act more like cats than dogs, making them good companions that don't require too much exertion - perfect for people who want a pet but lead busy lifestyles.
Because of their independence, they can be left alone without human interaction for extended periods.
Reserved adults often prefer Chow Chows because they are powerful and independent. However, this independence can make them challenging to train. They may also be aggressive and take some time to warm up to people.
Dutch Shepherd (224 PSI)
With a bite force of 224 psi, Dutch Shepherds are often used in law enforcement. But these dogs aren't just loyal and protective - they're also intelligent, making them great family dogs.
Recently, the Dutch Shepherd has become a more popular breed of Belgian herding dog in the United States.
They offer great intelligence and athleticism and typically have a stronger bite force than average--making them perfect for various working roles such as police dogs or search and rescue missions.
They're also amazing family pets because of their loyalty and ability to be trained properly.
Alano Español (227 PSI)
The Alano Español is a Spanish breed of dog that is used for various jobs, such as herding other animals, hunting, and safeguarding livestock.
Alano Español dogs are not for everyone. They're large, need a lot of exercises, and have one of the strongest bite forces with a pressure of 227 psi.
If you're considering this breed as a pet, make sure you have enough space for them to roam around.
Doberman Pinscher (228 PSI)
Doberman Pinschers are a popular breed for personal protection, thanks to their reputation for having a powerful bite.
The Doberman Pinscher is commonly chosen for personal protection due mainly to its surprising bite force. With a psi measurement of 228, these herding dogs can take down an assailant with little effort.

American Bulldogs can exert up to 305 PSI of pressure when they bite. Their powerful jaws make them one of the breeds with the strongest bite force.
The American Bulldog is an aggressive breed not recommended for families with small children, as it could be dangerous. This dog has the strongest bite force among most family dogs.
Rottweiler (328 PSI)
Rottweilers are large dogs that were initially bred in Germany. They are working dogs known for being guarding and loyal.
Rottweilers have a bite force of up to 328 PSI, easily allowing them to be one of the strongest dog breeds in terms of power. However, their bites are also particularly dangerous because they've been known to attack and kill people before.

Siberia Huskies are not only popular working dogs but also as pets. They are often used in dog sledding, carting, and racing because of their gentle nature and friendly temperament. Siberian Huskies weigh around 35 to 60 pounds and have a bite force of about 320 psi.
American Pit Bull Terrier (330 PSI)
The American Pit Bull Terrier is a breed extrinsically known for how strong they are. With a jaw that can exert up to 240-330 PSI of pressure, this Pitbull could take down an animal much larger than itself with little issue.
Despite their notoriety, Pit bulls are legal in the United States, with some towns and cities in Canada being notable exceptions to ownership rules.
Although Pit bulls are easy to train, people often forget that they need to be taught what behaviors are acceptable and which aren't.
Without this training, Pit bulls can become bitter. They are loyal and intelligent, making them one of the best guard dog breeds.
Akita Inu (350-400 PSI)
The Akita Inu is the only large breed native to Japan. They have a reputation for being powerful and able to cause severe injuries with their bite. For centuries, they have been used as hunting and fighting dogs in Japan.

If you're seeking a gentle giant that will stay by your side and make sure you're always safe, the Tibetan might be the perfect dog for you. Although it is illegal to own this dog in some countries because of its strong bite, many people find its loyalty and guardianship worth the risk.
English Mastiff (552 PSI)
Most kennel clubs recognize the English Mastiff simply as "the Mastiff."
They are among the world's giant breeds of dogs and are highly regarded for their even temperament and great strength.
English Mastiffs have a bite force that is among the strongest of all dog breeds. This is likely because they were bred to fight.
Cane Corso (700 PSI)
Cane Corso dogs were once ubiquitous throughout the country but are now primarily found in southern Puglia. They aren't as significant as other Mastiff breeds bred for work, averaging 110 pounds. This breed of dog has a bite force of 700 psi, making it one of the strongest breeds.
The Turkish Kangal (743 PSI)
The Kangal is an aggressive dog breed known as the Anatolian shepherd dog. Kangal is one of the breeds with the strongest dog bite force in the world.

The Kangal's bite is so forceful that it can kill predators instantly. Some countries have banned this dog breed because it is considered the most savage, with the strongest mouth bite globally.
"The sporting dogs were initially bred to help hunters take down large prey. These strong dogs have the instinct to kill and are more likely to attack humans than other breeds."

Does a Stronger Bite Mean a More Dangerous Dog?
Yes, a stronger bite means a more dangerous dog. The Tosa Inu and the Kangal have a large, muscular build with bites to match--the Tosa's bite is slightly more powerful than the other dogs. If either of these breeds attacks a human, it could result in severe injuries or even death.
Dog breeds with stronger bite force can cause more damage and are more dangerous. For example, a dog's bite force of 500 PSI can do considerably more damage than a dog's bite force of 100 PSI.
