The gwyllgi (Welsh pronunciation: [ˈɡwɪɬɡi]; compound noun of either gwyllt "wild" or gwyll "twilight" + ci "dog"[1]) is a mythical dog from Wales that appears as a frightful apparition of a mastiff or Black Wolf (similar to a Dire wolf) with baleful breath and blazing red eyes.[2] It is the Welsh incarnation of the black dog figure of English folklore.
