Black is generally pictured as “coal black”, completely devoid of any white, red or brown hairs. The guard hairs are consistently the same color all over the dog’s body although some reddening, or “sun burning” of the coat may appear in those dogs which spend time outdoors. The undercoat may be lighter in color particularly prior to shedding. The points (eye rims, nose, lips and pads) are black.
