Neapolitan Mastiff vs St. Bernard
Compare two breeds
Pick two breeds to see them compared side by side.
Neapolitan Mastiff
The Neapolitan Mastiff comes from southern Italy and is considered a direct descendant of the old Roman molossers used for both warfare and farm guarding. Its most striking feature is an abundance of loose skin, with deep wrinkles across the muzzle and neck, historically thought to protect the dog from bite wounds while fighting. A male can weigh up to 70 kilograms, with a heavy, slow-moving build unlike many other guardian breeds. The short, dense coat needs little upkeep, but the abundant skin can bring health concerns around eye and skin-fold infections. In temperament it is calm, dignified, and strongly territorial, known for serious rather than noisy guarding. Life expectancy runs 8 to 10 years, on the short end even for a giant breed.
St. Bernard
At a monastery pass in the Swiss Alps, founded in the 11th century by Saint Bernard of Menthon, monks used this breed to search for travelers lost in avalanches and blizzards. The legendary dog Barry is credited with saving over forty people during his working life. A modern male can weigh up to 82 kilograms, ranking it among the heaviest breeds on the FCI list. The coat comes in short or long variants, both dense and cold resistant. Despite the massive size, the breed is known for a calm, patient temperament, particularly around children. Drooling and heavy shedding are simply part of owning a dog this size. Life expectancy runs 8 to 10 years, short given the weight it carries.
