Few dogs look as dramatic as the Neapolitan Mastiff, a massive Italian guardian with loose skin, heavy folds around the head and a dewlap that hangs below the jaw. The breed grew out of the estate and farm guard dogs of southern Italy, and it was revived and standardized in Italy after World War II. Its short coat comes in gray, black, mahogany and tawny, sometimes with brindling, and its rolling, lumbering walk reflects sheer bulk rather than speed.
At home, many Neos are calm, affectionate and content to sleep for much of the day, while staying watchful and wary of strangers. Living with one means planning for a dog that can outweigh an adult, drools heavily, struggles in heat and tends to live a shorter life than smaller breeds. Patient, reward-based training and careful socialization matter a great deal with a guardian this strong.
