Neapolitan Mastiff History

The Neapolitan mastiff is a dog of ancient lineage, originally bred as a watchdog and livestock guardian. The origin of the Neapolitan mastiff is unknown, but it is likely that it descends from the Molossian type. In 1831, the first specimen of what is now called the Neapolitan mastiff was brought to England. From there, the breed became popular, especially in the south of England. The Neapolitan mastiff is also sometimes referred to as the “English” or “Old English” mastiff. Today, the Neapolitan mastiff is recognized by the Kennel Club (UK), the Fédération Cynologique Internationale (FCI) and the Federation Cynologique Internationale (FCI). The FCI describes the Neapolitan mastiff as “a big molossoid with a massive skull, wide forehead, low-set triangular or snipy ears and a wrinkled face”.
