What astonishing feat regarding neck extension can the Lundehund perform?

Answer

Folding its head backward so the back of its skull touches its spine

A demonstration of the breed's uncanny flexibility is its ability to severely extend its neck. The Lundehund can fold its head so far back that the posterior aspect of its skull makes contact with its spine. This extreme range of motion is highly advantageous because it permits the dog to look directly behind itself without needing to pivot or turn its entire body. This capability is invaluable when the dog is operating within narrow crevices or small caves where the angular limitations of turning are restrictive, allowing for effective scouting.
