Wargs

Wargs or Wild Wolves are a race of fictional wolf creatures in J.R.R. Tolkien's books about Middle-earth. They are usually in league with the Orcs or Goblins whom they permitted to ride on their backs into battle. The Wargs speak a rudimentary language of their own. It is probable that they are descended from Draugluin's werewolves of the First Age.

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, they are most prominently mentioned in the middle of The Fellowship of the Ring, where a band of Wargs, unaccompanied by Orcs, attacks the Fellowship in Hollin.
