Aug 31,2021

In many places around the world, dogs are known as the number one household pet choice. However, many of us are unaware of how dangerous some dogs could be if not raised well, due to their PSI strength. Here is a list of canines with the strongest bite forces in the world.

What is PSI strength?

Before we get into the list, you will notice every dog in the list will have a PSI, but what does this mean? This is a unit made to calculate the pressure released upon any given point and it stands for “Pressure per Square Inch”. For example, an average human bite is 162 PSI and a bear's is around 1,200 Psi. So where do our dogs come in on this scale?
