[Folklore] The black dogs are found all over the British Isles, especially on deserted roads. They are roughly the size of a calf and they move in utter silence, except for the clicking of their claws. The chill despondency and despair these dogs cause is the reason why there are no detailed descriptions of their appearance. While a companion is no guarantee for safety -- for one might see the dog and the other might not -- it offers a better protection than walking alone. It is said that the best companion is a descendant of Ean MacEndroe of Loch Ewe. He rescued a fairy once and in return he and his descendants were given perpetual immunity from the power of the black dogs. (See also Barghest).
