No dog breed has a bite that exerts 48000 pounds of pressure per square inch. In fact, no animal in the world has a bite that hard. I believe crocodiles have the strongest bite in the world, and among dogs, bite pressure per square inch averages around 320 pounds.
Pitbulls have the strongest bite. Bites have so many lbs. of pressure, they have the most lbs. of pressure when they bite. Krenshell- Pit bulls have the weakest bite pressure compared to GS, Rottie, Doberman, Mastiff.
