3 of 15


It’s possible that this breed’s name comes from the Latin word massivus, meaning massive. It’s certainly an appropriate description for a dog with a minimum height of 30 inches at the shoulder for males and 27.5 inches for females. Mastiffs have a weight range of 120 to 200 pounds or more.
