I want my Shih Tzu's hair to be long, but I don't know what to do on her face. I can't get the hair to lay down and I don't want it in her eyes. She is terrible about letting me do anything with her face. I don't have trouble brushing her back or legs. She is 6 months old. Will the face hair grow longer so it can be brushed down and tired up as she gets older. What do I do for her now?
