Basically the wolves are as fluffy (or not fluffy) as the other animals
Right now the game doesn't render any fur specifically (mostly for reasons of performance), except for the lion (but it only uses very basic fur).
Having said that, we've done some preparations for better fur rendering in general, while still keeping an eye on performance. We don't have an ETA yet, but once it's ready, it will make most animals more fluffy (please bear in mind that this is still work-in-progress and only provides a basic fur rendering - fully fledged fur rendering is not possible without killing the performance unfortunately)
