Warg
The Wargs or Wild Wolves are a race of fictional wolf creatures in J.R.R. Tolkien's books about Middle-earth. They are almost always in league with the Orcs or Goblins whom they permitted to ride on their backs into battle. The Wargs, according to Tolkien, speak a rudimentary language of their own.In The Hobbit, the Wargs appear twice, once in chasing Bilbo Baggins, Gandalf, and the dwarves just east of the Misty Mountains, and once at the Battle of Five Armies. In the Lord of the Rings trilogy, they are most prominently mentioned in the middle of The Fellowship of the Ring, where a band of Wargs, unaccompanied by Orcs, attack the Fellowship in Hollin.
