Uncommon But Muscular Dog Breeds
1. Norwegian Lundehund
The Norwegian Lundehund is a rare small Spitz breed from the remote islands of Norway. Originally bred in the 1600s to hunt puffins on cliffs, this dog is built for strength and balance. Its compact, muscular physique and natural agility helped it climb where other dogs could not.
Over time, new hunting methods and a dog tax nearly caused the breed’s extinction. Today, only about 250 Lundehunds live in the USA, making it one of the rarest dog breeds in the world.
Unique Physical Traits
Six toes on each foot with elongated rear pads for extra grip
Double dewclaws on the forefeet
