What must happen to the hind legs when viewed from the rear during the White Shepherd's correct trotting gait?

Answer

They should remain parallel, dropping straight to the ground.

Evaluating the White Shepherd's locomotion requires specific attention to the rear assembly, which provides the essential drive for movement. When the dog is executing the correct trot, the rear legs should move efficiently, propelling the dog forward. When assessed from behind, the hind legs must track parallel to each other, dropping straight down to the ground and pointing directly forward. Any tendency for them to turn in or out at the hocks constitutes a deviation from the ideal structural conformation necessary for efficient, sustained work.
