In terms of size, it has a length of 75 to 145 cm, including the tail, and a height between 35 and 40 cm. It is considerably smaller than the Iberian wolf. It weighs between 3 and 14 kg. Regarding its characteristics, it has a pointed snout typical of canids, although this one is even more so. As for its fur, it has a characteristic reddish-orange color, with white on the underside and tip of the tail, as well as darker paws and ear tips. However, the color can vary between orange and a darker shade close to black.

It feeds on small mammals, birds, insects, fruits, and berries. It stores food in its burrow for later consumption. It reproduces at the end of winter, and the gestation period is between 49 and 55 days. On average, 4 to 6 offspring are born. These offspring are born blind and helpless, which is why they remain in the burrow to be nursed for 8 to 10 weeks. After this time, they begin to leave the burrow, and after 3 to 4 months they are able to hunt. They become independent the following autumn. This species is more active during the day in spring and summer, while in autumn and winter it has more nocturnal habits. They are quite cunning and adaptable.
