My opinion is not worth much, but I think he looks Yorkie. Silkies were originally a cross between the two you mentioned, but they are now their own breed. I just wanted to clairify that so that they are not mistaken as one of today's "designer" crosses. Here are a couple of pictures of my Silky. I won't lie, I don't take too many body shots of her because you would all tell me she is part doxy!!!
