I have a Yorkie. Actually her hair is long but I don't have that problem with her face hair. Actually your Yorkie is still a puppy. I'd wet a paper towel and wipe off her face after she eats. Then you can give her face a quick comb through. You have to get a Yorkie puppie used to the comb and brush. It takes awhile but they do get used to it. I blow Tiffany's hair dry after a bath and that took awhile too. Good luck! Can you post a picture of her? I'll bet she's adorable!
