The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.
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. The breed was initially developed as war dogs and for the Roman coliseum spectacles.
In 1946 Dr. Piero Scanziani established a program to breed them in Italy. He wrote the breed standard in 1949.
Today the Neo is a farm dog, an army dog, a police dog and a guard dog. They were shown in Italy for the first time in 1946 but only in 2004 was the breed recognized by the American Kennel Club (AKC). It was 1973 when the Neapolitan Mastiff Club of America was born and 1996 when the standard was approved by the AKC. They are still a rare breed in the United States.
