What colors are Norwegian Lundehunds?
Norwegian Lundehunds come in a variety of colors, most commonly reddish-brown, fallow, white, or tan. Their coat is often layered, with darker tips on their fur, giving a slight gradient effect. The tips of their fur can range from black to a darker shade of their base color, adding a distinct outline to their overall look.
White markings are usually found on their chest, legs, and face. Some Norwegian Lundehunds may also have a darker mask, especially when they’re younger, though this can fade over time.
