History of the Breed
The name "Shih Tzu" comes from the Chinese word for "lion dog" because this dog was bred to resemble lions that were depicted in ancient Chinese art
DNA analysis proves that the Shih Tzu is in that group of "ancient breeds" that arose in China around the time of 800BC. Other ancient breeds include the Pug, Pekingese and Lhasa Apso.
In fact, the Shih Tzu is sometimes confused with the Lhasa Apso in appearance. But be aware that the temperament of these to dogs is very different. Shih Tzu were bred to be companions and Lhasa Apso were bred to be guard dogs. Thus, the Shih Tzu tends to be friendy and playful, the Lhasa Apso tends to be more aloof and wary of strangers.
Shih Tzu come in a variety of colors and color pattern. They can be recognized by their short snout and legs, dropped ears and large dark eyes. They have hair instead of fur, which means that their hair is silky and grows continuously. This means that they do not shed very much, but they also need regular grooming and trimming. Most Shih Tzu owners will have their dogs groomed every 4-8 weeks.
