I realized I didn't have an anthro reference sheet for Frodo's WindWolf form so I whipped this one out.
As always, no Frodo is not my boyfriend (sadly), nor is he a character I made up and named Frodo. This is Frodo Baggins from the Lord of the Rings drawn as a wolf (a WindWolf in this case).
In his WindWolf form Frodo should not be drawn with the Ring since this would be afterwards and in a slightly different universe. He should always be drawn with 4 fingers on his right hand though.
