Dogs have evolved over thousands of years to become highly specialized predators who rely on their powerful bite force to kill prey. This makes them very effective at hunting, but also means they can easily break bones or even tear off limbs.


Dogs are known for being loyal companions, but they can also be dangerous. If you want to keep your dog safe, you should always supervise him closely and never leave him unsupervised.

Before we start, let’s find out some facts about bite force in dogs.

The average human bite force is around 50-70 newtons (9.8 – 14.5 lbs), while the maximum recorded canine bite force is over 200 N (40 lbs).

A Labrador retriever with a bite force of 140 N (28 lbs) could seriously injure someone if it were to bite down on them. Although Labradors are not aggressive dogs, they have the capability to bite pretty hard!

How Is Bite Force Measured In Dogs?

To measure the strength of a dog’s jaw muscles, researchers use a device called an electromyography. It measures electrical activity in muscle tissue.

When a dog bites something, the jaw muscles contract and this causes the electrical signal to increase. Then, scientists take that electrical signal and convert it into a measurement of bite force using a formula.

Why Do Some Dogs Have Stronger Jaws Than Others?

There are many factors that influence how strong a dog’s bite force is. These include genetics, diet, exercise, age, breed, and size.

In general, larger breeds tend to have stronger jaws because they need more power to chew food. They also need more energy to run around chasing after prey.

Smaller breeds like Chihuahuas have smaller mouths which require less energy to chew. Their jaws are also weaker as a result.

However, there are exceptions to every rule. Some small breeds like Maltese have extremely powerful jaws.

What Is The Strongest Bite Force Recorded In A Dog?

The strongest recorded bite force was achieved by a German shepherd named “Sasha”. He had a bite force of 205 Newtons (42 lbs)! That’s almost twice the amount of the next strongest dog, a Doberman pinscher named “Buster”.

He was able to achieve his incredible results through training. His owner used positive reinforcement to train him to bite harder.

What Is PSI?

PSI is short for pounds per square inch. It is a unit of pressure that is used to describe the strength of a person’s grip.

It is calculated by dividing the weight of the object by its surface area. For example, if a person holds a hammer with a 10 pound weight and a 2 square foot surface area, then the PSI value would be 20.

Scientists use PSI values to compare different types of dogs. When comparing two dogs of the same breed, they can determine which one has a higher PSI value.

On with the list we go!

1. Boxer (230 PSI)


Boxers are big, powerful dogs that aren’t very aggressive. They’re friendly and playful, and they get along well with other pets.
