So precious! Well I am not sure on the styles and things being newer to the world of Yorkies, but what a cutie. If he tolerates brushing and top knots (if you want to do a top knot), I would go for letting it grow out a bit. But if he hates brushing, you could trim it up. I have seen both long and short haired boys and each are so cute!!! It's so hard to choose! A Yorkie is just cute no matter what you do with them! LOL. Katie Scarlett could of rolled in mud and leaves and I'd still think she was cute!
