The Norwegian Lundehund is a unique and ancient breed known for its distinctive traits and potential health concerns. One of the most distinctive traits of the Norwegian Lundehund is its polydactyl toes, which means they have more than the usual number of toes on each foot. This feature allows them to climb steep cliffs and navigate rocky terrain with agility. They are incredibly flexible due to their unique skeletal structure. They can bend their neck backward to touch their spine and have exceptionally mobile shoulder joints, which allows them to squeeze through narrow passages and retrieve birds from tight spaces.
