Days 1–3: 75% old food, 25% new formula
Days 4–6: 50% old food, 50% new formula
Days 7–9: 25% old food, 75% new formula
Day 10+: 100% new formula

Shih Tzus can be sensitive to rapid diet changes, particularly those prone to dental issues, skin allergies, and brachycephalic issues. Slow transitions minimize digestive upset and help you identify any intolerance to new ingredients.
