The Chihuahua and Shih Tzu are both popular small dog breeds, each with unique characteristics that may appeal to different dog owners. Chihuahuas, originating from Mexico, are known for their high energy levels and protective nature, making them excellent companions for those who enjoy an active lifestyle.
