Mouse
A tibetean temple dog.
Where is he from?
Mouse is a big awesome loveable temple dog featured in Jim Butcher's Dresden Files books, because there's no character in any story that you can't make better by giving him a dog. He never appeared in the 2007 Sifi adaptation series since he came later in the novel continuity, so for now we just have some fun fanart.
