The Neapolitan mastiff, also known as the Italian mastiff, is an eye-catching breed that has recently gained popularity throughout the world.

History and Origin

The Neapolitan mastiff is a breed native to Italy, dating back to 300 BC when the ancestors of the breed appeared with Alexander the Great. In ancient Roman times, Alexander the Great was known for breeding several large dogs together to develop a shorthaired dog known as the Molossus. The Neapolitan mastiff is considered to be a descendant of the Molossus.

In southern Italy, breeders wanted to create a mastiff that maintained the size and strength of the Molossus. They wanted a breed with a mean, serious look for protection, but gentle enough to stay at home with the family. From the Molossus and the Tibetan mastiff came the Neapolitan mastiff that had all the desired characteristics.

Until World War II, the Neapolitan was a treasured secret of Italy. Following the war, Italians began to promote the breed to the public. By 1973, the breed eventually made it to the United States and the Neapolitan Mastiff Club of America was formed. The Neapolitan mastiff has grown in population in the United States and in May of 2004, the American Kennel Club accepted the breed as a member of the working group.

Appearance and Size

The Neapolitan mastiff has a large head with many wrinkles and folds, drooping jaws and pronounced dewlaps. The eyes are set deep and hidden beneath drooping upper eyelids. The ears of the Neapolitan mastiff can be cropped or uncropped depending on the owner’s preference and the dog’s job. The body is heavily boned and well muscled with a tail carried straight up or curved slightly over the back. The coat is short and dense with uniform length over the entire body. The colors of the hair coat include solids of gray, black, mahogany, and fawn with solid white markings on the chest and toes of some dogs. The height of the Neapolitan mastiff is 24 to 30 inches at the shoulder and weighs between 100 and 150 pounds.


The Neapolitan mastiff is a sweet, affectionate and loyal companion. If necessary, the Neapolitan mastiff can be a formidable foe if his family is in danger.
