When your Shih Tzu turns up their nose at mealtime, it can be a little frustrating—and honestly, kind of confusing. These pups usually love their food. So when they suddenly refuse to eat, it’s natural to wonder what’s going on.

Before you panic, let’s walk through some of the most common reasons a Shih Tzu might skip a meal and what you can do to help.

1. They’re Feeling a Little Off


Just like humans, dogs sometimes have off days. If your Shih Tzu skips a meal here and there but seems fine otherwise, playful, alert, and hydrated, chances are they’re just having a moment. Keep an eye on things and see if their appetite returns the next day. But if they miss more than two meals or show other signs like vomiting, diarrhea, or lethargy, it’s time to call the vet.

2. Dental Pain or Mouth Issues


Shih Tzus are prone to dental problems due to their small mouths and flat faces. If your pup suddenly stops eating, check for red gums, loose teeth, or bad breath. Painful chewing is a major reason why dogs go off their food. A dental check-up could be the fix.


Pro tip: Regular brushing and dental chews can help prevent these issues before they start.

3. Picky Eater Habits

Shih Tzus are known for having discerning palettes. (Royal roots, remember?) If you’ve been switching foods a lot or giving too many treats, your pup may be holding out for the “good stuff.” Consistency is key. Avoid feeding from the table and stick to high-quality, balanced meals.
At Divine Pups, we feed our pups PawTree’s freeze-dried raw beef and whitefish kibble, which supports their digestion and keeps them thriving. It’s nutritious, delicious, and made to please even the pickiest eaters.

4. Stress or Environmental Changes


Has anything changed lately? A move, travel, a new pet, or even a different feeding spot can throw your Shih Tzu off. These pups are creatures of habit. If something shifts in their world, their appetite might take a temporary hit. Try feeding them in a quiet, familiar space to help them settle.

5. Underlying Health Issues


Loss of appetite can be a symptom of something deeper… like kidney problems, infections, or digestive issues. That’s why it’s so important to monitor for other symptoms and talk to your vet if things don’t improve after a day or two. Better safe than sorry.

6. They’re Not Actually Hungry


This one might seem obvious, but sometimes your Shih Tzu just isn’t hungry, especially if they’ve had too many treats or snacks between meals. Watch their portion sizes and stick to a regular feeding schedule. A little “tough love” can help get their appetite back on track.

In Conclusion


A Shih Tzu refusing food can be a sign of something minor or something that needs attention. Start with the basics: rule out treats, check their mouth, and watch for signs of stress. If you’ve ruled out pickiness and routine changes and they’re still not eating, don’t wait to consult your vet.And remember, nutrition plays a huge role in keeping your Shih Tzu healthy and happy. That’s why we only use PawTree’s premium food and supplements here at Divine Pups. It gives our dogs the fuel they need to grow strong, stay energized, and thrive long after they leave our home.
