BLUE OR GREY The called Blue or Grey Border Collie is due to the presence of a dilute gene, so the deepness of black color is blended, to bluish, slate or dark grey. As well as it happens with other coat colors, the differences are easily seen on puppies (better than on adults, whose coats gets darker).
Today the Border Collie is recognized as the premier sheepherding dog. The breed's superior herding ability leads many fanciers to advocate breeding Border Collies only to working, not conformation, standards. The Border Collie was recognized by the American Kennel Club on October 1, 1995.
