Alice Borchardt writes fantasy involving werewolves. Pretty sure the werewolves are the good-guys (or at least, not evil simply because they're werewolves) in her books.
S. Andrew Swann wrote a couple, but I think the wolves are the bad guys, although it's a sort of twist (they're creatures used by the templars in their crusades, if I remember correctly).
I know of lots of shapeshifters/werewolves in the romance genre, but I get the feeling that's not what you're looking for, plus, they're more in contemporary contemporary/urban setting.
Gail Carriger has a steampunk 5-book series including werewolves and vampires. There is a romantic element, but this is more along the lines of urban fantasy, although it's set in Victorian times.
