The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Obsolete names for the breed include Shepherd's Dog and bob-tailed sheep-dog.[1] The nickname Bob-tail (or Bobtail) originates from how dogs of the breed traditionally had their tails docked. Old English Sheepdogs can grow very long coats with fur covering the face and eyes and do not shed unless brushed.[citation needed]
