Shih Tzus are one of the most popular breeds of dogs. They originated in Asia, during Tang and Ming Dynasties, and have been known for being a symbol of royalty. They also stand out because of their lion-like appearance. These dogs come in a variety of colors including bringle, silver, red, gold, blue, and black. The colors may be combined, or they may be just one single color. Shih Tzus have double coats, but unlike other dogs with double coats, they actually shed very little. These dogs are even recommended for people with allergies and asthma.
