White & Blue

The AKC lists White & Blue as a registration color for breeds including the Rat Terrier and American Hairless Terrier. The AKC Rat Terrier standard defines pied as comparatively large patches of one or more colors combined with white, and includes blue among accepted colors. The UKC American Hairless Terrier standard permits blue in the coated variety and requires some white, without fixing its location or size. Those coated-variety rules are separate from the hairless variety’s skin colors.
