The Norwegian Lundehund is a small and agile Spitz breed with several unique characteristics in combination not found in any other dog. Features such as six toes on each foot; prick ears that fold closed, forward or backward at will; and the ability to tip the head backward until it touches the back bone all helped them perform their job as Puffin hunter. Their dense coat ranges from fallow to reddish brown to tan in color, with black hair tips and white markings, or white with red or dark markings.

Their superior personality, even disposition and small size make them an ideal, easy-to-live-with pet, although they may be wary of strangers. Consistency in the home environment is extremely important, as is consistency in training, house training, and socialization. Lundehund is very sensitive and can develop trust issues with an owner who tries to trick him into doing things – you can only fool a Lundehund once. They are incredibly clever and fun-loving, making them delightful and sometimes challenging.
