Something that some people either need to know or are simply interested in knowing is the bite force of different dog breeds.

In this guide, we look at how different breeds rate on the bite scale in terms of bite pressure and bite force.

Bite Force (Strength) Of Different Dog Breeds, & A Comparison To Other Animal Species’ & Humans

 

How Bite Force Is Measured?

Bite force is generally measured in pounds per square inch (psi), and not in Newtons.

There’s several ways bite force experiments might be carried out, and how they are carried out can have a large impact on results.

The most accurate way might be with a force measuring device that is placed in the mouth.

 

Dog Breeds With The Strongest Bite Force

Measured in psi:

  • Kangal – 743
  • American Bandogge – 730
  • Cane Corso – 700
  • Dogue De Bordeaux – 556
  • Tosa Inu – 556
  • English Mastiff – 556
  • Dogo Canario – 540
  • Dogo Argentino – 500
  • Wolfdog – 406
  • Leonberger – 399
  • Akita Inu – 350 to 400
  • Rottweiler – 328 
  • Siberian Husky – 320
  • African Wild Dog – 317
  • American Bulldog – 305 
  • Doberman – 245
  • German Shepherd – 238
  • Great Dane – 238 
  • American Pit Bull – 235
  • Labrador Retriever – 230 
  • Boxer – 230
  • Alano Espanol – 227
  • Dutch Shepherd – 224
  • Chow Chow – 220
  • Malinois – 195

 

How Dogs Compare To Other Animal Species

  • Lions and White Sharks – around 600 pounds
  • Hyena – around 1000 pounds
  • Nile alligator – 2500 pounds

*For perspective, 2000 pounds of bite pressure is roughly the equivalent of the force that the weight on a small subcompact automobile would put on something when it is on in. 

 

How Animals Compare To Humans

Human bite force is around 120 pounds.

 

Asterisks On Bite Force

Psychologytoday.com wrote an interesting piece on bite force and we paraphrase from that article:

  • Bite force can differ depending on if you’re measuring at the back or front of the jaw – force measured at the front of the jaw can in some cases be only a quarter of the force compared to that at the back of the jaw. The back of the jaw is where the lever principle works most strongly
  • Bite force can differ depending on if you are measuring with Newtons, or pounds of force (A Newton only equals 0.22 pounds of force i.e. one fifth)
  • How bite force is measured can matter i.e. how the experiment is conducted. Is it done with a force-measuring device, or is it only calculated and estimated based on the makeup of the jaw structure?
  • Bite force might differ depending on how provoked and angry an animal is
  • The size of the animal and the shape of it’s jaw are usually good predictors of bite strength – The larger the dog and the dog’s head, and the wider the jaw, generally the stronger the bite force
