Blue Merle & White

Blue merle combined with white. Cardigan Corgis have black-and-grey marbling, with white flashings usual on the neck, chest, legs and other areas. Collies have blue-grey-and-black marbling with their usual white markings; Shetland Sheepdogs have varying amounts of white or tan. Old English Sheepdogs also permit blue merle with white markings.
