About the Neapolitan Mastiff

The Neapolitan Mastiff is a massive, ancient guardian breed from southern Italy, known for its extraordinary loose, wrinkled skin, massive head, and powerful build. Descended from the great war dogs of ancient Rome, the Neapolitan Mastiff was developed in the Naples region as an estate guardian and protector. Their imposing appearance — with heavy folds of skin, a lumbering gait, and a weight that can exceed 150 pounds — makes them one of the most intimidating-looking breeds in the world.
