Among various factors that determine a dog’s strength, its bite force is an important one. The severity of a dog bite injury highly relies on the animal’s bite force. It is the reason why certain breeds are associated with fatal dog attacks more than others.
A dog’s bite force is measured in pounds per square inch, PSI. It is the measure of a dog’s jaw strength and directly correlates with the severity of its bite. The bite force of a dog is measured by using an instrument called a “bite force meter.”
During the test, dogs are encouraged to bite a sensor pad with a specific object or dummy. The sensor measures the maximum pressure exerted by the animal’s jaw. Measurements can vary depending on the dog’s health, stress levels, and bite angles.
Here are some dog breeds with the strongest bite force in the dog world.
