Cavalier King Charles Spaniel

The Cavalier King Charles Spaniel was created in the early twentieth century to recreate the longer-muzzled spaniel type seen in old portraits from the era of King Charles II, who adored such dogs. It differs from the shorter-faced King Charles Spaniel mainly in its longer nose and flatter skull. At around 8 kilograms, it is one of the most popular toy breeds in the world, though it carries a known predisposition to heart valve disease, which makes health screening in breeding lines especially important. The long, silky, slightly wavy coat needs regular brushing. Temperament is exceptionally friendly, rarely aggressive, and it gets along well with children and other pets. That devotion to people can tip into separation anxiety if left alone too long. Despite its small size, it still needs a daily walk. Life expectancy runs 10 to 14 years.

Shih Tzu

The name Shih Tzu means little lion in Chinese, and the breed was kept for centuries in the Chinese imperial court as a palace companion, likely descended from Tibetan dogs given as gifts to Chinese emperors. The long, dense, flowing double coat in its full show form needs either constant brushing or a shorter trim to avoid matting, since it is rarely left to grow untended. The short muzzle gives the breed its trademark chrysanthemum face, where the coat radiates outward from the nose in every direction. Despite its decorative role, the breed reaches up to 8 kilograms on a compact, sturdy frame rather than a fragile one. In temperament it is friendly and easygoing, better suited to life as a companion than as an active outdoor dog. Life expectancy runs 13 to 16 years.
