Although sometimes long, a Shih Tzu will not always have extremely lengthy hair like the Pekingese (but with short legs). Some of them have more short, curly hair. Because of their long coat and fast-growing hair, regular grooming is necessary, which may be expensive and should be taken into account when considering adopting one of this breed. Often, the coat is clipped short to simplify care, but the coat still requires daily brushing. For conformation showing, the coat must be left in its natural state, though trimming for neatness around the feet and anus is allowed. It usually affects middle-aged dogs and is seen in all breeds. Symptoms include hair loss, weight gain, muscle loss, and lethargy.
