The winter fur is soft and tall, with short, dense underfur and long, sparse guard hairs. The summer coat is shorter and coarser than the winter fur, and is not as dense and close-fitting, with a more strongly developed ochreous or reddish tone. The ears are completely white, while the throat is yellowish-white or almost white. Sometimes, the head is entirely white. The lower part of the neck is dark blackish-brown or brown, while the chest and front legs are black or blackish-brown. The abdomen is light, yellowish-straw in colour.
