This rare breed isn't hunting puffins anymore, but their unique features speak to their past: they can tip their head back until it touches the backbone, they have six toes and their ears can fold backward, forward or closed. The Norwegian Lundehund is an energetic and playful breed. He's protective of his family and may be wary of strangers. Norwegian Lundehund puppies need sensitive training and socialization and can sometimes be a challenge. But once you establish trust, you'll have delightfully friendly, clever and fun-loving companion.
