Its relatively small legs are beige to fawn in color, with individual black hairs that turn lighter to white towards the legs. The soles are heavily coated with fur that fully covers the pads, an adaptation to extremes of temperature in the desert, that probably helps to distribute its weight and move easily on sand. The back has a black speckling, resulting in a thick black patch at the base of the tail, which is bushy with a white tip. The fur is very soft and fluffy in two coats, a heavier denser winter coat and a thinner summer coat. The females have three pairs of mammae.
