Neapolitan Mastiff


An ancient breed with roots going back to war dogs used by the Romans, the Neapolitan Mastiff retreated into obscurity until the breed was rediscovered in Italy in the 1940s. With its massive size and imposing look created by its loose folds of skin, the Neapolitan is a daunting and commanding guard of livestock, estate, master, and family. The AKC recognized the Neapolitan Mastiff as a member of the Working Group in 2004.
