When testing footing on uneven ground, how does the Lundehund's movement differ from a typical dog's approach?

It seems to hook its foot into the texture of the surface using the additional digits

Observing a Lundehund move across varied, challenging ground reveals a specialized testing methodology for footing that differs from other canines. Where a typical dog might simply push down onto a surface to test its stability, the Lundehund utilizes its extra digits to actively secure itself by seeming to 'hook' its foot into the inherent texture of the surface before fully committing its body weight onto that limb. This hardwired physical structure provides superior stability before weight transfer occurs.
