What is PSI? Measuring the Strength of a Dog’s Bite:

A dog’s bite strength is measured by pounds per square inch or PSI for short. This is the amount of pressure applied per square inch of one pound. PSI is not exclusive to a dog’s bite strength. It is also used to measure pressure in tires and atmospheric pressure.

In general, the larger the size of the dog, the bigger its mouth, and hence, the stronger its bite is. The strength of a dog’s bite also depends on the shape of its jaw and the size of its skull. The pressure that a dog’s bite exerts may depend on the kind of material they are biting.[/box]
