What colors are Icelandic Sheepdogs?
Icelandic Sheepdogs’ coats come in several colors, including shades of tan (from cream to reddish brown), chocolate brown, gray, and black; white markings are common but are never the predominant color. The most common white markings are a blaze on the face, chest, socks, or tips of their tails. Icelandic Sheepdogs with tan and gray coloring often have black face “masks” and black on the tips of their tails.
