than that of northern foxes. It is the smallest subspecies of red fox inhabiting Eurasia; adults attain a body length of , a tail length of , an ear length of and a weight of .

Generally, dull-yellowish or grey tones predominate. The head is sandy or yellowish-creamy in colour, with a whitish muzzle. A dark grey, reddish-brown or blackish-brown band is present in front of the eyes. The outer surface of the ears are either pure black or brownish-black.

The throat, chest and belly are whitish or grey. The feet are grey with dark stripes. It is not overly exploited by the

Its reproduction is much more prolonged than that of northern foxes; pairs are formed in November, and begin mating throughout December and January. Kits are born in February–March.
