Dog bites are very serious injuries. Every dog in the world is capable of inflicting a bite, no matter its size or personality, according to dog bite statistics. However, some breeds of dogs have stronger jaw muscles than others, along with larger jaws, and can do more damage. This is why the right training with an animal behaviorist is essential when you adopt a new dog, especially for first-time dog owners.

A dog’s jaw strength is measured in pounds per square inch PSI, a figure that’s derived from evaluating the adductor muscles. The strongest dog breed in terms of jaw strength using this measurement is the Kangal, with the highest bite force at 743. But there are many others that come close.  

All dog owners, no matter how friendly their pet is, should also know how to treat a dog bite should one occur. Quick action can be the difference between life and death. 

Dogs with Strongest Bite Force

There are hundreds of dog breeds in the world, each with its own personality type and characteristics. Through extensive testing and studies, scientists and researchers have been able to assign many dogs a rating. Here are the top dogs with the strongest bite force:

Measures to Take in Dog Bite-Related Injuries 

If you experience a dog bite or are around someone who has, there are a few short but critical steps to take to prevent a more serious injury or infection.  

First, make sure to try to control the bleeding. In some cases, this might mean applying a tourniquet. If one isn’t available, tie a strap of cloth just above the bite. Then, clean out the wound as best as possible. This might mean running warm water over the wound, using hydrogen peroxide, or applying ointment. Cover it to protect it against further contamination. 

It’s important to seek medical attention, no matter how minor the bite looks, because it can get infected quickly. There are a number of bacteria in a dog’s mouth that can transfer to your bloodstream.  

Most states require you to report dog attacks, and when you do this, make sure to also document all of the details surrounding the bite. When did it happen, what type of dog, its owner, and any witnesses to the biting incidents.  

In some cases, legal action may be necessary, especially if the bite is serious enough to warrant ongoing medical attention. 


Is a Dog’s Increased Danger Linked to its Stronger Biting Capability? 

Not exactly. While dog breeds with the strongest forces can inflict more damage, that doesn’t necessarily make an average dog more dangerous. There are a number of factors that go into what makes them a dangerous animal, and one of the key components is its handling.  

How Serious are Dog Bites? 

The answer to this question depends on two main factors: how big is the bite, and where did it occur? For example, a bite on the arm could be less serious than a bite on the neck due to the location of the body’s major veins and arteries.

However, any dog is capable of inflicting a fatal bite if it does so in the right spot, so the answer is a dog bite can be very serious. Even if it’s not a fatal bite that hits a major vein or artery, a bite can become quickly infected if not treated properly.  

How Is the Bite Strength of a Dog Measured? 

A dog’s bite force is measured in PSI, pounds per square inch. Those carrying out studies use different methods to measure bite strength, including a bite force transducer or through electronic stimulations of the jaw adductor muscles. 

Which Dog Has the Weakest Bite Force? 

The dog with the weakest bite force is also one of the smallest dogs you can find — the Chihuahua. However, despite this, it’s still important to handle any breed of dog with care, as even those with weaker bite forces can be dangerous.


Ever since the domestication of dogs, our four-legged friends have been well-known for being friendly animals, but the truth is our furry friends can bite at any time, and sometimes, without warning.

It’s a good idea to be educated about bites and how to handle them in order to ensure there’s no lasting damage. And remember, even if you know the dog, always exercise caution.
