How long can a shih tzu go without food?

A Shih Tzu can typically survive without food for about 3 to 5 days, but this varies based on the dog's age, health, and hydration levels. However, going without food for even a day or two can lead to health issues, including weakness and lethargy. It's important to consult a veterinarian if a Shih Tzu refuses to eat for more than 24 hours to ensure there are no underlying health concerns. Always prioritize their well-being and provide a balanced diet.
