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. The shorter cut is typically called a 'puppy cut' or a 'teddy bear cut' when the puppy cut is accompanied by a fuller, rounder face, resembling a cute and cuddley stuffed animal. In comparison with many other breeds, Shih Tzu do not shed to the same degree, only losing small amounts when bathed or brushed. It is the dog's dander and saliva that trigger most allergic reactions. The coat may also be wavy or coarse. A number of health issues, some of them hereditary, have been found in individual Shih Tzu, and are listed below.
