Although neither of the parent breeds of the Shorkie Tzu tends to shed, they have very different coats and can produce a coat in their Shorkie puppies that require a variety of grooming measures. That difference is that Yorkshire Terriers have single coats of silky hair whereas Shih Tzus have double coats with a dense outer hair and a soft, silky inner hair. In any case, Shorkie grooming will require moderate to high effort, and if you elect to let your cute little Shorkie have floor-length hair, you will need to set aside a lot of time for daily brushing, frequent bathing and heavy grooming. Most people, however, tend toward the puppy cut — a style that keeps the hair short, easily managed and relatively free of debris.
The puppy cut (essentially short all over) can be done at home with a bit of patience. If it is your first time attempting a simple cut, however, you may want to watch an online video on how to groom a Shorkie. As for bathing, it need not be done except every 2-3 months at the most.
