Anybody have a good, free-to-use picture of a big, shaggy black dog?

Now that I've had to take down my website I've decided to revamp it a little bit before I re-upload it - give it a LoM and a games/Knytt Stories section etc. - and one of the small things I've always been meaning to fix is swapping out the very unfitting dog picture on the Remus/Sirius page. Any help would be appreciated...

All the links (well, nearly all of them) are still dead, of course.
