Which Dogs Have the Strongest Bite?

When choosing a dog, many factors come into play, including temperament, size, and trainability. However, one often overlooked but crucial trait is bite force, which is measured in pounds per square inch (psi). This metric determines how much pressure a dog can exert with its jaws. For reference, the average human bite force is around 162 psi—but some dog breeds far exceed this number. The UK Kennel Club recognizes several powerful breeds with exceptionally strong bites. Whether they were originally bred for guarding, herding, or hunting, these dogs boast impressive jaw strength, making them formidable working animals and loyal companions when properly trained. So which dogs have the strongest bite?

Many of these breeds, including the Kangal, Rottweiler, and German Shepherd, have proven their loyalty, intelligence, and protective instincts time and again. If you’re considering a strong-jawed breed which has one of the strongest bites, ensure you provide the right training, environment, and care to help these dogs thrive as loving, disciplined pets.
