Norwegian Lundehund

The Norwegian Lundehund is a small rectangular and agile Spitz breed with unique characteristics not found in any other breed. Originating on remote islands of arctic Norway, the dog was used to wrestle and retrieve live puffin birds from the crevices of steep vertical cliffs. To enable the dog to climb, descend, and brake on these cliffs, unique structural characteristics have evolved and must be present as they define this breed: a minimum of six toes on each foot and elongated rear foot pads; an elastic neck that allows the head to bend backward to touch the spine, letting the dog turn around in narrow puffin bird caves; and shoulders flexible enough to allow the front legs to extend flat to the side in order to hug the cliffs. This shoulder structure produces a peculiar rotary movement. Finally, the ears close and fold forward or backward to protect from debris. The temperament is alert but not expected to be outgoing toward strangers.
