An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
