You could always check out a book on Belgian Shepherds, scan photos from the book in...if you know how to do it. It's a thought. If I was in any way skilled with PhotoShop, I'd totally hook you up with a doctored photo of Dean with one of the shepherds you found. But alas, I suck. Still, you should put the word out, see if someone's willing to help you out--I bet it would be awesome!
