What the jaw pressure of an American mastiff?

The American Mastiff has a strong and powerful jaw, capable of exerting significant pressure when biting. While specific measurements can vary, it's estimated that their bite force can range from 500 to 700 pounds per square inch (psi). This impressive strength is characteristic of large breeds, allowing them to perform tasks that may involve gripping or holding onto heavy objects. However, individual bite strength can vary based on factors like age, health, and size.
