What is the mandatory restriction on how the Whippet's tail must be carried?

Answer

It must never be carried over the back

The tail serves as a visible indicator of the dog's physical conformation, particularly when viewed in profile relative to the hindquarters. The tail itself is described as long and tapering, set low on the body. Crucially, its carriage is strictly defined by the breed standard: it should hang down or curve slightly upward, but it is explicitly forbidden from ever being carried over the dog's back. Maintaining the correct tail carriage ensures a clean, unbroken line extending from the slightly arched loin, which is a hallmark of the ideal sighthound silhouette.
