What is stated regarding the Lundehund's sixth toe compared to the extra dewclaws occasionally seen in other breeds?

The Lundehund’s extra toes are integrated and must be functional for the breed standard

The Lundehund's characteristic six toes are fundamentally different from incidental extra dewclaws seen in breeds like the Great Pyrenees or Beauceron. In the Lundehund, these digits are fully integrated components of the paw structure, contributing directly to locomotion and grip, and are explicitly required to be present and functional to meet the breed standard. Conversely, dewclaws in other breeds are often structurally different, sometimes vestigial, and may even be removed for safety reasons in contemporary settings, illustrating the crucial distinction between a defining adaptation and an occasional anomaly.
