Largely considered to have descended from dogs used by the Roman military, Neapolitan Mastiffs originate from Italy. After World War II, Piero Scanziani began breeding the local Italian mastiff-type dogs, giving rise to the formal dog breed known today.
It is believed that the first dogs were wolves that were domesticated by humans at some point during the Paleolithic stone age. All the modern breeds of dogs are descended from these domesticated wolves. (yes, the chihuahua is a wolf :)
