It was in the region of Tibet that the Shih Tzu breed of dogs beheld its initial origin. It is generally believed that the Shih Tzu breed of dogs are a mixture of the Tibetian Mountain Dogs and the Pekingese breed of dogs, being a cross between the two breeds. Having believed to possess a disposition that pronounces loyalty, the Shih Tzu breed of dogs has inherited this trait from the Emperor of China, who gave favorable treatment to this very breed, having a strong penchant for the dogs of this breed. This fact is authenticated from the evidence of Chinese paintings, which also portray the royal treatment, which was given to the Shih Tzu breed of dogs by the Emperor of China. It was during the early half of the twentieth century that this breed was introduced in Europe (in England) and were soon introduced in the United States as well after the end of the Second World War.
