The second gene determines coat pattern. It can produce animals with no saddle (essentially all-tan, but called 'red' in bloodhounds); ones with saddle-marking; or ones largely covered with darker (black or liver) pigment, except for tan lips, eyebrows, forechest and lower legs. However, more modern study attributes the variation to 3 different alleles of the Agouti gene. In Medieval hunting the typical use of the Bloodhound was as a 'limer', or 'lyam-hound', that is a dog handled on a leash or 'lyam', to find the hart or boar before it was hunted by the pack hounds (raches).
