Estimates put the number of Lundehunds at around 1,500 in the world, and only around 250 live in the United States. Originally from Norway, Lundehund means “puffin dog.”And it’s not just the six toes that make folks take a second look. The Lundehund is extremely limber. They can turn their heads a full 180 degrees, rotate their legs over their heads, and even lie completely flat, with all four legs sticking straight out to the sides.
