Huan the Hound
Large wolfhound of Beren and Luthien. Huan the Hound assisted the couple on the quest of te Silmaril. He was first brought from Valinor by the Valar to Middle-Earth, where he befriended Celegorm. The two were best friends until Celegorm mistreated Luthien in Nargothrond. Huan then abandoned Celegorm and befriended Luthien. He killed off wolves of Sauron for her and battled Sauron head-on by the Forest of Tol-in-Gaurhoth. He killed Carcharoth. Huan was very loyal and was well-respected, but after the Battle, Huan's wounds killed him. Beren was saddened much by Huan's death, for he accompanied him to his death-bed.
