1. Dog 'Shih Tzu' As the name suggests, the Shih Tzu is a Chinese dog. It is commonly believed that the breed was developed over a long period of time by crossing the Lhasa Apso from Tibet with Pekingese, specifically for the Chinese imperial court. The reason for specifically creating the Shih Tzu was probably to produce a breed that looked more like a lion, which is a symbol of Chinese culture..
