The Hound of Sauron
 

In the Fellowship of the Ring, after the fellowship abandon Caradhras but before they enter Moria, they are attacked by a band of Wargs. There is a fight, and many are killed. However,
What exactly were these creatures?
They seem intelligent, as Gandalf speaks to one of them, and this combined with their disapearance leads one to believe that they were not ordinary wolves.
Were they ordinary Wargs which were being controlled by Sauron, like the birds who acted as his spies, and who then caused their bodies to disapear?
Or where they another kind of monster?

I think Wargs are of higher intelligence than Wolves so maybe they carried away their dead instead of leaving them lying.

But Orcs wouldn't do that. I'm not sure, but it's an outside possibility.

We had a pretty interesting conversation on this topic a while back -- see it here.

Thanks for the topic. It's quite an old one, so I must have missed it.
