The breed is steady, good-natured and playful, with a clownish streak, and some try to herd the people around them. In Britain it became widely familiar through decades of paint advertising. Paul McCartney's Old English Sheepdog, Martha, gave her name to a Beatles song.
It is a thickset, square-built dog whose topline rises from shoulder to loin, so the rump stands higher than the withers. The profuse, shaggy coat is hard-textured over a dense undercoat. It is usually grey, grizzle or blue with white on the head, chest and forelegs, and hair often falls over the eyes. Puppies are born black and white, and the dark areas lighten as they grow. At a walk it moves with a rolling, bear-like amble, and the British standard describes a loud bark with a distinctive cracked ring.
The Old English Sheepdog, often linked to the West Country though its origins are obscure, moved into the show ring in the later nineteenth century, when dogs of the type were first exhibited and a breed club was formed in England. Fanciers in Britain worked to fix a more uniform appearance, and the breed's working role with drovers gradually gave way to life as a show dog and companion.
