The Shih Tzu may be a small dog, but these pups are not short on personality. It is an ancient small dog breed that can be traced back to the 1600s in Chinese art, making it one of the oldest dog breeds on record. These historically beloved small dogs are known for their sweet demeanor and boisterous opinions. Their brachycephalic muzzle means they are better lap dogs than running companions, as they can’t tolerate high temperatures. So if you are looking for a cuddly, fluffy small dog breed, the Shih Tzu might just be the one for you. Just remember that their fluffy coat will require some maintenance to keep it at its best.
