Bite strength is in terms of PSI or pounds per square inch. To measure this force accurately, a dog must bite the sensors with its full power. The measuring devices have edible substances tempting the dog to chew them. 

Studies indicate that dogs with large heads, big bodies, and broader jaws have more bite power. To analyze the strength, we have a few bite strengths for you to compare.
