The Alpine ligurian poem R sacrifisi dr can, written in Ligurian, tells of how a shepherd shot his sheepdog after finding it covered in sheep blood, only to later find a dead wolf in the stable.
Tom Shippey, in The Road to Middle-earth (pp. 193–194) says that the hunting of the great wolf recalls the chase of the boar Twrch Trwyth in the Welsh Mabinogion, while the motif of 'the hand in the wolf's mouth' is one of the most famous parts of the Prose Edda, told of Fenris Wolf and the god Týr; while Huan recalls several faithful hounds of legend, Garm, Gelert, Cafall.
