I imagined him like a wolf, but more doggish, if you take my meaning. But I imagined him as a wolf until I read the part where he fought Sauron. Then he looked more like a dog in my mind. I'm not sure why.
Mm...i chose a long time how Huan might look like.Tolkien writes that he was a hound. But it`s unclear whether this suit or appointment.I saw Irish wolfhounds too, but ... they seemed too daunting outwardly. At least for a good character. For example www.arahu-iw.com/images/storie… or
Wow I really like the first image ! We probably have an imagination working differently ^^ Cause I always pictured Huan fighting Charcharoth like that (I even do a sketch that looks a lot like this picture... funny).
For me Huan is a hound and Charcharoth a wolf, that's clear. But he can be a type of hound looking a lot like a wolf (cause it's a looong time ago) or more like a dog (I like Irish Wolfhounds cause they are tall and are a really old race from the british islands which make them believable in ME).
I met an Irish Wolfhound once and for me it can really play the role of the faithful and nice Huan, wise in some occasions too. It's normal for him to look really fierce when it come to fighting.
It was awesome. I don't like big dogs usually, they scare me, but this one looks really cool and wise, he was playing with the young children like an ol' granda'. But yeah it's a huge dog, I'm sure he was able to carry a child on his back (if it remembers you something) !
