Also,Huan could have been a Maia in the form of a wolfhound,since we all
know Maiar can change their form,or no?
It could have been a Maiar in the service of Orome,who took a form of a wolfhound,
and might have been equal or even more powerfull then Sauron,them beign both
of the same order...
...I know it sounds unlikely but...Maiar can take the forms of animals
and humans alike so...
