Cotswold sheep are usually calm and friendly. They mostly have white faces, but their faces are occasionally mottled with some light grey or tan hairs. Small black spots may occur on the “points” (non-woolly portions of legs, ears, and face), but the wool itself is white. Kemps (coarse hairs) are normally absent from the wool.

Cotswold hooves are normally black, but may sometimes be streaked with light or translucent colour. Foot rot is very uncommon in this breed. Cotswold rams occasionally have small scurs but they do not have horns.

Cotswold sheep do not have the tight-flocking instinct of western range sheep, preferring to spread out and graze enclosed pastures more uniformly. Some strains of the breed are not as prone to internal parasites as others, provided their grazing is not excessively short.
