An ancient breed, the Neapolitan Mastiffs are massive dogs with a history of protecting their family and their property. The breed has deep rooted protective instincts and they are very frightening in appearance. The Neapolitan is of the Molosser group of dogs, all of whom probably came from the same line. It is known that all the mastiffs in Europe are descendants of the Tibetan Mastiff. The Tibetan Mastiff is considered the most ancient of all canines.
The Asian Mastiffs came from India to Greece around 300 BC with Alexander the Great. Then the breed was brought to the Romans by the Greeks and then introduced them in their circus in fights. Another possibility is that around 500 BC the mastiffs came to Britain from the Phoenicians. Either way the Roman Molossus is the ancestor of the Neapolitan Mastiff.
The Romans crossed the breed with the English Mastiff around 55 BC and developed a premiere war dog that was called a Mastini.
The breed eventually became extinct in Europe with the exception of Campania. The breed was recognized in 1946 with the standard accepted in 1949. However, it is believed that the Neapolitan Mastiff has been continuously present in Campania for over two thousand years.
