Our Mastiff Sign features a distinct and recognizable black silhouette of this breed, surround by the words Caution, Area Patrolled by Mastiff Security Co. If the size of your pet were a direct indicator of ferocity, any strangers would be deterred. However, our Mastiff Sign could be displayed as an expression of pride in your pet, with affection not fear being the motive. Each Warning Sign is durable and weather resistant, made from high impact styrene, and measures 11 x11 inches. Our Mastiff Guard Sign could simply indicate that your visitors need to make room for a gentle giant.
