Covered with dags (locks of wool matted with dung), as in sheep; shabby or unkempt.
From dag (noun), meaning a hanging lock of wool. The word comes from Middle English, possibly of Scandinavian origin, applied especially to sheep's wool condition.
Farmers developed 'dagging' as a surgical art because matted wool on sheep can cause serious infections—it's a veterinary procedure with centuries of refinement!
