How strong is an African mastiffs bite?

The African Mastiff, also known as the Boerboel, has an exceptionally strong bite force, estimated to be around 800 to 1,000 psi (pounds per square inch). This powerful bite, combined with their muscular build, makes them effective protectors and formidable guard dogs. Their bite strength is among the highest of all Dog Breeds, reflecting their history as working dogs on farms in South Africa.
