At a glanceShedding separates selected sheep from a group under the requirements of the particular trial course.WORKING DOG reference library · Added 2026-10-19 · Editorial guideObserve the separationWatch which sheep are required and what the handler and dog must do to demonstrate control. Simply seeing a mob divide does not establish a completed trial shed.Check the courseSelection, completion and handler movement depend on the rules. Do not assume that every three-sheep, yard or herding event includes the same exercise.Using this referenceUse this explanation to understand the term in context. For an entry decision or disputed result, check the current rules and the original event documentation; a glossary cannot replace the authority’s decision.Keep selection visibleIf the course requires particular sheep, a wide view and identifiable markings help explain the task. A cropped separation may conceal which animals left the group. An educational explanation should state what is known from the course and what remains unclear from the available footage.Sources & further readingReferences for this guide.
