some researchers have noted that at maximum attack mode, a wolf's bite force can be over 1000 PSI. Did your dog make the cut? All these dogs are ranked by their bite force which is measured in Pounds per Square Inch or PSI. This is not a reflection of any single animal and should only be taken as a scientific study.

What is PSI?
PSI is a unit made to calculate the pressure released upon any given point. The full meaning of psi is "Pound per Square Inch" or "Pound-force per Square Inch". PSI is a measured result of all the pressure applied over one square inch of a pound. It is a very commonly used system and is easy to understand for even some of the most scientifically challenged people. To understand this a little better, take a tire for example. The average tire's pressure generally falls around 32 psi or pounds per square inch. PSI is the scientific method used to explain the force that a dog is able to put forth through their bites. This list documents the twelve strongest dogs based on the psi system.Meanwhile, the PSI that the jaws of animals will make use of is normally average.



However, the pressure may vary based on - What gets bitten, Feelings of the dog - its mood, The dog itself. If compared, while humans make use of an average bite force that ranges from 120-140 PSI, the Nike crocodile's bite force is 5,000 PSI. Well, the bite force of the average dog is placed around 230-250 PSI even though some of these dogs have more strength. Measuring the exact bite force of dogs gets very complicated.

Strongest Bite?


1. Kangal
Dog with the Strongest Bite!
Bite Force - 743 PSI
