In a national Geographic test to see which dog had the strongest bite the American Pit Bull had an approximate bite force of 235 pounds. With these kinds of test it is often difficult to get accurate results since you can't train a dog to consistently keep its bite pressure the same throughout the test, and to bite as hard as it possibly can. You can watch this experiment at the link posted below.
A hyena's bite measures at 1000 pounds of force. A pit bull's bite measures at 235 pounds of force.
235 lbs/sq in pounds of force
A crocodile definitely produces much more bite force. Herpetologist Brady Barr measured the bite force of a great white shark at 669 pounds (303.45 kg). However, this is probably not the best bite force that a great white shark can produce. But, in any case, the shark has such razor-sharp teeth that he doesn't need a greater bite force. He also measured the bite force of a crocodile of South Africa at 2500 pounds (1133.98 kg)! After that, he measured the bite force of a very big Nile crocodile at 5000 pounds (2267.96kg)! This is also the most powerful bite ever measured from any animal. And that was still a defensive bite, despite the brute force that this crocodile produced, as it bit the bite meter only when it was brought in its mouth, while it was resting. If this crocodile had bitten the bite meter while charging at it, especially in water, the bite force would have been even greater.
Pit Bull Bite: 235 pounds of force German Shepherd: 238-750lbs pounds of force Rottweiler: 328 -350lbs pounds of force Lion: 691 pounds of force Hyena: 1000 pounds of force Dog bite strength is proportional to the size of the dog. Bull Terrier is a relatively small dog averaging 128 to 200 pounds. So a Staffie's bite would be somewhere below 235 pounds of force, depending on his size.
Pit Bull Bite: 235 pounds of force doberman Bite: 200 to 400 pounds of force German Shepherd: 238 pounds of force Rottweiler: 328 pounds of force Lion: 691 pounds of force Hyena: 1000 pounds of force.
Pit Bull Bite: 235 pounds of force German Shepherd: 238 pounds of force Rottweiler: 328 pounds of force Lion: 691 pounds of force Hyena: 1000 pounds of force Dog bite strength is proportional to the size of the dog. So of the four listed breeds, the pit bull would on average have the least bite force, the bull mastiff would average the highest bite force, and the German shepherd, rottweiler, and bouvier would be between. Of course, a dog's bite strength on any given bite can vary widely, dependant on the level of agitation and bite-inhibition of the particular individual. The answer-changing nonsense below does nothing to answer the question and is entirely falsified. German shepherds have the most powerful bite. Current bite pressure record is 450-1000lbs (made by a German shepherd) their average bite pressure is 450 pounds

The bite force of the ferret is about the same as a large dog's bite. They have powerful jaws and very sharp teeth.

The Orca's bite force has not been measured because it's virtually impossible to measure the bite force of an aroused bull Orca under controlled conditions. Note that bite force is measured in lbf, not psi. Estimates range from 2000 lbf to 10,000 lbf. Measuring bite force in psi would require defining what surface you were measuring on - the tip of the tooth? across the entire jaw?
