The Cava-Tzu dog is a breed that was produced by crossing the Cavalier King Charles Spaniel and the Shih-Tzu dogs. These are dogs that have a moderate to dense coat and with a look very similar to the shih-tzu. Known for their funny attitude and cute looks, the small-sized cava tzu has a round face, round, dark, button-like eyes, a black, glossy nose, and with a pair of ears hanging loose almost reaching their neck. They retain their cute, teddy-look even at old age. Being a loyal, affectionate dog, they make a wonderful companion, a great foot-warmer, and an entertaining family dog.
