What food to give 3 week old shih tzu?

At three weeks old, a Shih Tzu puppy is typically still nursing and may not be ready for solid food yet. If the mother is unable to nurse, you can introduce a high-quality puppy milk replacer. If the puppy is transitioning to solid food, a soft, moistened puppy kibble or specialized puppy formula can be offered. Always ensure fresh water is available and consult a veterinarian for personalized feeding advice.
