Scientists have measured the biting force/PSI(pounds per square inch) of various dogs.
The top 3 dogs with the strongest bites are
Rottweiler
German Shepherd
Pitbull
The Rottweilers were the strongest and topped with 328 pounds of bite pressure. German Shepherds came in second with a 238 measured bite force, and the American Pit Bull Terrier came in third with 235 pounds of pressure.
How does that measure compared to cousins in the wild?
Dogs are at a disadvantage. A wolf’s normal bite force is around 400 pounds. If it is protecting itself, a large wolf can bite down with over 1,200 pounds of pressure.
Large cats are very strong. A Jaguar can reach 700 pounds of pressure, and Siberian Tiger 950.
You might not think of Hyenas as strong, but even though they are scavengers they also hunt, and most of the time they chase down their own food. A hyena can bite down with 1100 pounds, and they’ve been known to chase off lions to claim food.
I once got bitten by a German shepherd pale nyeri after I entered the wrong home for a burial, luckily the owner was near, otherwise I’d have lost my foot
