The Strongest Dog Bite Force by Breed (Top 20)

The friendships between humans and dogs date back over 15,000 years, after the domestication of dogs. As the first animals to be domesticated, strong bonds developed between master and hound. Dogs’ natural hunting, herding, retrieving, and other skills made them important companions to farmers, hunters, and nomads. The inborn traits of some breeds even earned them critical role players in wars. Unfortunately, sometimes the strongest dog bite force per breed is in dogs with a history as trained fighting dogs.

Humans and canines have worked and lived together for centuries, and dogs are often the result of their training. Good or Bad. A simple example is dog owners who neglect to socialize and train their dogs. Worst still are those who train their dogs to fight or be vicious. Any dog can bite, regardless of the breed. A provoked Jack Russel, like a provoked Boxer, is likely to attack. We can say the about a Chihuahua and a Belgian Malinois. The severity of the injuries they cause depends on which one has the strongest bite force.

How do They Measure a Dog’s Bite Force?

The force of a dog’s bite is measured in PSI–pounds per square inch. Researchers use digital bite meters to determine bite force. They categorize the dogs into nine categories, based on their skull shape and breed size.

PSI indicates the pressure that a dog’s jaw uses at any given point. It’s a very common measurement system; also used to measure car tire pressure. The pressure released by a dog’s jaws differs based on what they are biting. A dog would not release the same amount of pressure biting a toy as it would in a defensive situation.
