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.

The Akita Inu is showered with love and admiration not only by the Japanese but also by the entire world because of the stout heart and working spirit they possess. While this breed has a couple of commendable traits, the potential is there for this dog to attack with deadly consequences.
The Akita Inu can slam its scissor-like jaw shut with up to 400 PSI and you really couldn’t force the dog to open its mouth until it decides to let go. Its sheer size alone is a reason why this breed is feared by some.
