Biting power in dogs: These 7 breeds have the most power
Dogs have been man's friend and helper for many millennia. In order to also be able to protect humans, it is not surprising that they have also developed great biting strength over the years. Even if this characteristic is less important for dogs nowadays, the biting power is still present. Depending on the breed, this strength can vary greatly.
Many strong biting breeds are also listed dogs. However, this often has nothing to do with their temperament, but is only related to their high biting strength. An example of this is the Rhodesian Ridgeback, which is listed in Switzerland.
PSI as a measuring unit
In order to make the values comparable, scientists have developed a unit with which the biting force can be measured. The unit describes the mass that acts on a certain area. PSI stands for pounds per square inch.
In order to be able to classify the values better, you get three comparison values here:
- Human: 120 to 140 PSI
- Wolf: 400 PSI
- Hippopotamus: 1800 PSI
