The top of the head, forehead, under and between the eyes, and between the eyes and ears is gray with a reddish film.

The muzzle is pale ochreous gray, and the area of the lips, cheeks, chin, and throat is white.

The coat of the Eurasian wolf is a mixture of ochreous (yellow to orange) and rusty ochreous (orange/red/brown) colours with light gray.

Wolves usually have some hairs that are white, brown, gray and black.

A wolf's coat colour is determined by its guard hairs.

Hair length on the middle of the back is 60–70 mm (2+3⁄8–2+3⁄4 in), and the guard hairs on the shoulders generally do not exceed 90 mm (3+1⁄2 in), but can reach 110–130 mm (4+3⁄8–5+1⁄8 in).

Winter fur is retained longest by lactating females, although with some hair loss around their teats.

Older wolves generally have more white hairs on the tip of the tail, along the nose, and on the forehead.

Female wolves tend to have smoother furred limbs than males and generally develop the smoothest overall coats as they age.

In warm climates, the fur is coarser and scarcer than in northern wolves.
