Shih Tzus were palace dogs in China, developed from small Tibetan dogs presented to the imperial court. The name comes from the Mandarin word for lion, and the first dogs reached England around 1930 and the United States after World War II. Today's Shih Tzu is a sturdy toy dog with a short square muzzle, large dark eyes and a long, flowing double coat in almost any color.
Many Shih Tzus are friendly, outgoing and happiest close to their people, and they usually get along with visitors and other pets. Dogs vary, though. Care centers on the coat, which needs brushing every day or two or a short trim every few weeks, plus attention to the eyes, teeth and breathing that come with a flat face. Shedding is low, but the breed isn't hypoallergenic.
