While every dog has the ability to bite, did you know that their bite force varies significantly? Bite force is a fascinating characteristic, impacted by the dog’s size, jaw structure, and even emotional state. Whether it’s the intimidating Kangal or the loyal Labrador, each breed has its unique bite strength.

This article will take you through the dog breeds with the strongest bite force, explain how dog bites are measured, and discuss what these figures mean in practical terms.
Understanding Dog Bite Force
What is Bite Force?
Bite force is measured in pounds per square inch (PSI), which tells us the pressure a dog can exert with its bite. The PSI measurement offers an insight into how powerful a dog’s bite can be, influenced by factors like body size, skull shape, and jaw strength.
For comparison, a typical human bite is between 120 and 140 PSI, whereas some dog breeds can reach several hundred PSI. While bite strength alone does not determine aggression or temperament, it can indicate a dog’s potential to cause harm if not properly trained or handled.
How is Dog Bite Force Measured?

Scientists and experts use specialized tools to measure bite force accurately. Much like measuring air pressure in a tire, these instruments record the force exerted when a dog bites down. The PSI is calculated by dividing the total force by the area over which the force is applied.
The following are the top 20 dog breeds with the strongest bite force, ranked by their PSI.
