Things to consider:

  • This breed may be less suited to smaller living spaces.

The Neapolitan Mastiff developed in southern Italy from the region's long tradition of large guardian and mastiff-type dogs. Similar heavy dogs had existed around farms and estates for generations, where their intimidating appearance and physical power made them useful property guardians. Romantic accounts sometimes trace the breed directly to Roman war dogs, but an uninterrupted pedigree from ancient Roman animals to the modern Neapolitan Mastiff cannot be demonstrated. The breed as recognized today was shaped much more recently. After the Second World War, Italian writer and dog enthusiast Piero Scanziani became an important advocate for the surviving mastiffs around Naples. He helped bring attention to the dogs at exhibitions and contributed to efforts to establish a formal breed standard. Selective breeding emphasized the massive head, loose skin, heavy bone, and characteristic wrinkles now associated with the Mastino Napoletano. The breed gradually gained recognition in Italy and spread internationally during the second half of the 20th century. The American Kennel Club recognized it in 2004. Although its dramatic appearance is now a defining feature, the Neapolitan Mastiff's fundamental historical role was straightforward: it was a formidable guardian whose size, confidence, and appearance alone could discourage threats to a home or property.
