Old English sheepdog
a large, compact dog distinguished by its profuse, shaggy, gray and white coat that covers the body, including the face, and obscures most of the body features. The tail is either naturally short or docked to a very short length. Called also the English bobtail. The breed is predisposed to congenital deafness, myelopoietic disorders, inherited cataracts and demodectic mange.
