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).
Although the Border Collie is bred for its abilities and natural herding instinct rather than for appearance, they were officially recognized by the American Kennel Club in 1994 and are now allowed to compete in conformation classes (for AKC Championships).
