Ozotoceros bezoarticus is a medium-sized, lightly built cervid. Head and body length is 110 - 140 cm, shoulder height is 70 - 75 cm. The prevailing color of the upper parts and limbs is reddish brown or yellowish gray. The face, crown, and tail are darker. Coat color is richer on the back than toward the extremities. Cream-colored areas occur as tarsal tufts, inside the ears, around the eyes, chest, throat, underparts, and underside of the tail. There is no marked difference between summer and winter pelage. Pelage of newborns is chestnut with a row of white spots on each side of the back and a second line from the shoulders to the thighs. The spots disappear by about 2 months of age, leaving a russet juvenile coat.
Males are slightly larger but there is no marked sexual dimorphism in size, weight, or pelage. Only males have antlers, that consist of three tines: a lower or front prong of the main fork and the upper or posterior prong divided. A synchronized antler cycle exits. Antlers are shed in mid winter, a new set begins to grow immediately and racks are cleaned of velvet by early summer.
It was suggested a latitudinal size gradient with northern animals larger. Three subspecies have been described based on geographic variation of the color coat. Ozotoceros bezoarticus bezoarticus is pale red-brown, O. b. leucogaster is tawny-brown, and O. b. celer is bay.
