Understanding the Unique Nutritional Needs of a Shih Tzu
Body Size and Metabolism
Shih Tzus are small dogs, typically weighing 8–16 pounds. Because of their compact size, they burn calories quickly and need high‑quality protein to maintain muscle mass. A balanced diet should contain 18–22% protein and 14–16% fat.
Common Health Concerns
These dogs are prone to dental issues, eye problems, and joint stiffness. Foods enriched with calcium and phosphorous support bone health, while antioxidants help protect eyes. Omega‑3 fatty acids improve skin and coat quality, which is especially important given the Shih Tzu’s long, silky fur.
Digestive Sensitivity
Many Shih Tzus have sensitive stomachs. Choosing foods with easily digestible proteins, such as chicken or turkey, and limited fillers like corn or wheat, reduces the risk of upset stomach, itching, and flatulence.

How to Read Dog Food Labels: Key Terms for Shih Tzu Owners
First Ingredient
Look for a specific animal protein, such as chicken or salmon, instead of generic “meat” or “protein.” The first ingredient should reflect the main protein source.
Guaranteed Analysis
This section shows the minimum protein, fat, and moisture levels. Compare these figures to your Shih Tzu’s needs.
Life Stage & Breed Size
Premium brands mark the food with “Adult Small” or “Senior Small.” This ensures the kibble size and nutrient balance fit a Shih Tzu’s life stage.
AAFCO Statement
All commercial foods must meet the Association of American Feed Control Officials (AAFCO) standards. This guarantees the food is nutritionally complete.
Grain‑Free vs. Whole Grains
Grain‑free foods use alternative carbohydrates like sweet potato or peas. For most Shih Tzus, moderate grains are fine, but grain‑free is essential if they have allergies.

- Always provide fresh water.
