The second of three episodes on The Silmarillion Chapter 19, "Of Beren and Lúthien." Man's best friend has a soft spot for Elf-maidens too, as Huan the hound of Valinor befriends Lúthien and assists in her quest to fetch Beren from the dungeons of Sauron. We find two sons of Fëanor off their leash, bury the bones of a beloved Elf-king, and dig up some of Tolkien's essays and letters to determine the difference between wolves, wargs, and werewolves. As it turns out, not all dogs come from heaven.
