Dog Bite Force Chart: Fact vs. Fiction – Is the Kangal Really 743 PSI?

Dog Bite Force Chart:

Fact vs. Fiction –

Is the Kangal Really 743 PSI?

If you've scrolled through social media, you've likely seen eye-catching charts ranking dog breeds by "strongest bite force." One popular version looks like this:

American Pit Bull Terrier (APBT) – 234 PSI

Dogo Argentino – 500 PSI

Presa Canario – 650 PSI

Cane Corso – 700 PSI

Bandogge – 730 PSI

Kangal – 743 PSI

These graphics are dramatic and get plenty of shares, but how much of this is actually true?

Understanding Bite Force (PSI)

Bite force is measured in pounds per square inch (PSI) — the pressure exerted by the jaws. Larger dogs with bigger heads and stronger jaw muscles generally have higher bite forces. However, accurate measurement is surprisingly difficult. It depends on the individual dog’s size, motivation, health, and the testing method (e.g., bite sleeves with sensors vs. biomechanical estimates based on skull shape).

Most widely shared numbers come from unverified internet lists that get copied repeatedly — not from large-scale, peer-reviewed scientific studies.

Breaking Down the Chart

Here’s what the popular chart claims, alongside more realistic context based on available estimates and tests:

American Pit Bull Terrier (APBT): 234 PSI

This figure is one of the more consistent ones across sources. For a medium-sized dog, it’s respectable, but not exceptionally high compared to larger breeds.

Dogo Argentino: 500 PSI

Often quoted around 300–500 PSI. Bred for big-game hunting, they have strong, sustained grips, but real-world tested figures tend to be lower than the chart suggests.

Presa Canario: 650 PSI

Estimates usually range from 500–550 PSI in more cautious sources. These powerful Canary Island guardians are undeniably strong, but 650 PSI appears inflated.

Cane Corso: 700 PSI

Frequently listed between 500–700 PSI. As a large Italian mastiff-type, they rank among the stronger domestic dogs, though exact numbers vary widely by individual.

Bandogge: 730 PSI

A crossbreed (often mastiff x bully types), so strength varies. Some estimates place powerful individuals in this range, but it’s not a standardized pure breed.

Kangal: 743 PSI

This is the most debated number. The Turkish Kangal (a livestock guardian) is repeatedly called the strongest, but many experts consider the 743 PSI figure a myth or exaggeration. It likely originated from a misread study or decimal error. More realistic estimates for large Kangals fall closer to 500–700 PSI at the high end, though they are still among the most powerful due to their size and jaw structure.

Key takeaway: The ranking order (Kangal and mastiff-types at the top, APBT lower) makes general sense — bigger, heavier dogs tend to have stronger bites. However, the specific PSI numbers are often overstated for dramatic effect, especially for the larger guardian breeds

Why Bite Force Isn’t the Full Picture

A high PSI number doesn’t automatically make a dog more “dangerous.” Real-world bite risk depends far more on:Temperament and socialization

Training and owner responsibility

Individual personality (not breed alone)

Context (fear, protection, pain, etc.)

Many strong breeds, including Kangals and Cane Corsos, are known for calm, loyal dispositions when properly bred and raised. Conversely, any dog can bite under the wrong circumstances

Final Thoughts

Viral bite force charts are fun to look at, but treat the exact numbers with caution. True bite force varies significantly between individual dogs of the same breed, and reliable scientific data is limited.If you're researching breeds for family, protection, or working roles, focus on temperament, exercise needs, training requirements, and responsible breeding — not just jaw strength. A well-trained, socialized dog of any breed is far safer than an untrained one with a “weaker” bite.Have you seen this chart before?
