About the Shih Tzu
The Shih Tzu is a small, affectionate companion bred for centuries as a palace dog. One of the longest-lived small breeds, Shih Tzus are sturdy despite their silky appearance and thrive on human company.
Caring for a Shih Tzu
Coat maintenance. The long double coat requires brushing every one to two days. Many owners keep a shorter 'puppy cut' to reduce grooming demands.
Breathing. Shih Tzus are brachycephalic — their flat faces can cause breathing difficulties. Avoid strenuous exercise in heat.
Eye care. Prominent eyes are vulnerable to injury and dryness. Check and wipe daily; see a vet promptly for any redness.
