Neapolitan Mastiffs are the ultimate guard dog. They’re enormous, they’re ferocious-looking, and they have a useful habit of approaching a stranger quietly before barking. They’ll never love anyone but you, and you probably feel the same way. You can say it with this personalized Neapolitan Mastiff T-Shirt. Care: 100% cotton. Machine wash warm, no bleach, tumble dry low, warm iron. Available in Infant, Toddler, Youth, and Adult sizes. Personalize your t-shirt by using the "Personalization" box below.
