Barghest
In Northern English folklore, the Barghest or Barguest is a mythical monstrous black dog with large teeth and claws; however, in other cases, the name can refer to a ghost or household elf, especially in Northumberland and Durham, such as the Cauld Lad of Hylton. == Origin of the name == "Ghost" in Northern England was pronounced "guest", and the origin is thought to be of the combination burh-ghest, "town-ghost".
