We can thank the selective breeding of a Tibetan dog in ancient 17th century China for the modern-day white Shih Tzu. During this era, Shih Tzus were regarded as royal dogs and weren’t introduced into Europe until the 1930s. Despite its playful and friendly demeanor, the Shih Tzu shares a close bond with wolves. Surprisingly, this ancestry link with wolves is closer than many more aggressive-looking dogs share with wolves.
White Shih Tzu are loyal, friendly, and affectionate dogs, hence their popularity as great companion dogs. They are naturally non-aggressive though they have been known to exhibit possessive behavior around other canines.
