Grooming a pet, particularly a high-maintenance breed like the Shih Tzu -- can be a challenge. With this breed, grooming habits include daily brushing and combing and trimming the facial hair to prevent eye infections. You can opt to keep the hair straight, or you can learn intricate hairstyles like a topknot. It is also necessary to keep a Shih Tzu's face dry to prevent tear stains caused by the growth of red yeast. One way that you can do this after a bath is by using a hair dryer.
