A friend of mine got one of these dogs, and I thought the canine was so odd that I did a bit of research.
The have 6 real toes on every foot! Traction on the rockly ledges!
It has a number of features to allow it to get into tiny tunnels and crevices as it hunt the puffins.
The Lundehund’s forelegs bend outwards so far that the dog can lay flat on its chest to wriggle into small spaces.
The dogs neck and spine are extremely flexible, so they can turn around in the smallest spaces! I can't think of another mammal that can touch the top of its head to its spine.
