At a glanceA boundary marks the intended edge of an area in tending work. It can be represented in different ways.WORKING DOG reference library · Added 2026-10-19 · Editorial guideRead the layoutBefore interpreting a boundary exercise, locate the intended grazing area and the edge described by the organiser or instructor. A boundary in a course diagram is not automatically a physical fence. The observer needs the layout and task context to understand what a dog is being asked to influence.An example of ambiguityA dog travelling beside a strip of mown ground might be following a working boundary or simply moving along a convenient path. A photograph alone cannot settle that question. Ask for the course description and explain which interpretation the source actually supports before labelling the image as an assessed tending exercise.Avoid importing another course’s rulesA defined sporting boundary can carry specific requirements within its own class and authority. Do not assign those requirements to every farm scene or historical breed image. Keep the course identity with a result and seek supervised instruction for practical work instead of constructing an exercise from a simplified reference drawing.Common questionsDoes boundary always mean a stockproof fence?No. The task description and layout identify what the boundary represents.Sources & further readingReferences for this guide.
