20 Dog Breeds With The Strongest Bite Force (and how it’s measured)

February 6, 2021 Kar-Bay-Inc 0 Comments

One of the factors of dog’s strength is the bite force. So do we know what dog breeds have the strongest bite force? Yes, and it can be measured scientifically. The bite force of any animal is measured in Pounds per Square Inch (psi). This unit of pressure tells how much force is exerted on one square inch of space. The psi that the jaws of animals will exert is usually averaged.

The pressure can be different depending on the substance being bitten, the mood of the dog, and even the dog itself. To give you a comparison, humans have an average bite force of 120-140 psi, and the Nile Crocodile has a bite force of 5,000 psi. The bite force of average dogs ranges somewhere around 230-250 psi, but some have more strength.

Let’s focus on the dogs for now. Even though nowhere as strong as Nile Crocodile’s bite, the force of strong dog’s bite won’t only rip through flesh, but it could also break bones. Below we’ll list dogs that have the best chance of doing exactly that. If you’re considering owning one of these strong dog breeds, it is very important that you work with a professional dog trainer to ensure your pooch doesn’t show any signs of aggression.

Most breeds on this list are dogs that are considered to be aggressive. Those are the animals that usually get their bite force measured. What is important to remember, is that any dog can become aggressive if neglected and abused. Most dogs are not loners.

Myths about dog’s bite force, and the scientific truth

There’s a lot of misinformation about dog’s bite force out there, with some articles saying that certain dog breeds have the bite force strength of 2,000 pounds. That’s stronger than a bite force of a full grown adult hippo (yes, this thing). Obviously, this is wrong.

The only two studies measuring bite forces of dogs are the by Ellis et al and Lindner et al.

The results of the study were reported in Newtons, with some of the highest numbers coming at 2,000 Newtons. From here, many websites took the number and incorrectly interpreted it as psi, which in fact is around 450 pounds per square inch (not 2,000 psi).

Why some dog breeds have stronger bite force than others?

Majority of the bite force strength in dogs depends on the size of their body and skull, and the shape of their jaw. Dogs with largest heads and subsequently biggest jaws all had the strongest bite force, which explains why Mastiffs ranked the highest of all dog breeds.

Now without further ado, here are the dogs with the strongest bite forces in the world. Just so you know, they will all be greater than yours. Every dog’s bite is dangerous, but these ones could be especially brutal if they exert their full force.
