What Does “A Wing of Sheep” Mean?
“Wing” most plausibly comes from sheepdog herding terminology, where the “wings” of a flock refer to its outer edges, the sections a working dog manages and adjusts to steer the whole group in a particular direction. This vocabulary remains active today in sheepdog trials, competitive events where handlers direct dogs through precise herding courses, and commentators and judges regularly reference how well a dog works a flock’s wings while gathering or driving sheep through gates and obstacles.
Managing a flock’s wings effectively is a genuinely skilled part of practical sheepdog work, not just competition; a dog that can read and adjust a flock’s edges lets a shepherd move sheep efficiently without the group breaking apart or scattering. “A wing of sheep” likely describes exactly this, the flank section of a larger flock, a specific, functional piece of herding vocabulary rather than a term for an entire independent group.
Example: “The dog swung wide to bring the wing of sheep back in line with the rest of the flock.”
