About Neapolitan Mastiff

Ancient Italian giant guardian with massive build and heavy wrinkles. Calm and affectionate with family, wary of strangers, and protective by nature. Needs early training, steady leadership, moderate daily walks, and careful skin and drool care due to size and loose folds.
