# Lundehund

> Profile of the Norwegian Lundehund, a spitz breed with six functional toes, extreme joint flexibility, and closeable ears adapted for puffin hunting in cliff crevices. Brad covers its near-extinction after puffin hunting bans and the resulting genetic bottleneck.

Let's talk about one of the most unique dogs in the world—the Norwegian Lundehund. This isn't just another spitz breed; it's a dog that evolved some truly bizarre features to hunt puffins in the remote islands of Norway.

Here's where it gets crazy. The Lundehund has six toes on each foot. Not just little extras, but full, functional toes with extra joints. That gives them insane grip on rocks and slippery surfaces. They also have super flexible shoulders that let them splay their legs out completely flat, like a frog. And their neck? It's so bendy, they can tilt their heads backward until it touches their spine. Why? So they can maneuver inside tight rock crevices without getting stuck.

But here's the catch—this breed almost vanished. When puffin hunting was banned, people stopped breeding them, and by World War II, there were only a handful left. They were hit with a genetic bottleneck, meaning today's Lundehunds all come from a tiny pool of ancestors. That makes them incredibly rare, and it also means they have some unique health quirks.

They're the only dog breed in the world with six fully developed toes on each foot
Their neck flexibility is unmatched in the dog world—they can bend their head backward 180 degrees
They can close their ears completely to keep out water and dirt
Their shoulder joints are so flexible they can rotate their forelegs 90 degrees from their body

The Lundehund isn't just another rare breed—it's a living example of how dogs can evolve incredibly specific traits to perform incredibly specific jobs.
