Shih Tzus have big personalities and small digestive systems. If your dog has ever had gas, loose stools, or a skipped meal after a new snack, you know how quickly a treat can go wrong. Many store-bought options contain rich fats, artificial flavors, and fillers that are hard on a toy-sized stomach.
This guide covers why Shih Tzus are prone to digestive upset, which ingredients tend to be gentle, and how to bake a simple batch of mild treats at home.
Why Shih Tzus Often Have Sensitive Stomachs
Shih Tzus typically weigh only 9 to 16 pounds, so even a small dietary change has a big effect on their bodies. Common reasons for digestive trouble include:
- A small digestive system. A few extra bites of a rich treat can be enough to cause upset.
- Sensitivity to fatty foods. Rich, greasy treats are a common trigger in small breeds.
- Food sensitivities. Some Shih Tzus react to ingredients such as wheat, corn, soy, or certain proteins.
- Eating too fast. Many small dogs gulp treats, which can lead to gas or an upset stomach.
If your dog has frequent vomiting, ongoing diarrhea, or sudden changes in appetite, see your vet. Homemade treats can’t treat a medical condition, and persistent symptoms deserve a proper checkup.
Ingredients That Tend to Be Gentle
When baking for a sensitive stomach, keep the ingredient list short and simple. These are commonly well tolerated by dogs:
- Oats. Rich in soluble fiber and usually easy to digest. For a longer look at this ingredient, see our oatmeal dog treat recipe for sensitive stomachs.
- Plain pumpkin. A well-known source of fiber that many owners use to support regular digestion.
- Banana. Mild, naturally sweet, and an easy binder (in moderation, since it contains sugar).
- Unsweetened applesauce. Adds moisture without added sugar.
- Egg. A simple binder and protein source for dogs that tolerate it.
Ingredients to Avoid
Some foods are unsafe or likely to upset a delicate stomach:
- Xylitol, an artificial sweetener found in some peanut butters and baked goods, which is toxic to dogs
- Chocolate, grapes, raisins, onions, and garlic, all of which are harmful to dogs
- Excess salt, sugar, and fat
- Dairy, since many dogs have trouble digesting lactose
- Artificial colors, flavors, and preservatives
Always check labels on anything you add, such as canned pumpkin (it should say 100% pumpkin, not pie filling).
Gentle Shih Tzu Treat Recipe
This recipe makes about 40 tiny treats, sized for a small mouth. It uses only a few mild ingredients.
Ingredients
- 1 cup oat flour (blend rolled oats into a fine powder if needed)
- ¼ cup plain canned pumpkin
- 2 tablespoons unsweetened applesauce
- 1 egg
- 1 to 3 tablespoons water, as needed
Instructions
Step 1: Preheat. Heat your oven to 325°F (163°C) and line a baking sheet with parchment paper. A slightly lower temperature keeps the treats from becoming too hard.
Step 2: Mix the wet ingredients. In a medium bowl, whisk together the pumpkin, applesauce, and egg until smooth.
Step 3: Add the oat flour. Stir in the flour until a soft dough forms. If it feels dry, add water a tablespoon at a time. If it’s sticky, add a little more oat flour.
Step 4: Shape. Roll the dough to about ¼ inch thick and cut it into very small pieces, roughly the size of a pea or a small button. Tiny treats are easier to chew and easier to portion.
Step 5: Bake. Bake for 18 to 22 minutes, until the treats are firm and lightly golden.
Step 6: Cool. Let the treats cool completely on a wire rack. They will firm up further as they cool.

How Many Treats Is Too Many?
For a Shih Tzu, portion size matters as much as ingredients. A good rule is that treats should make up no more than 10% of daily calories. For a dog this size, that often means only a handful of tiny treats per day.
To avoid upset:
- Start with just one or two treats the first time.
- Wait 24 hours and watch for gas, loose stools, itching, or vomiting.
- Increase gradually only if your dog does well.
- Offer treats between meals rather than right before or after a big meal.

Storage Tips
Homemade treats have no preservatives, so store them carefully:
- Room temperature: Up to 5 days in an airtight container
- Refrigerator: Up to 2 weeks
- Freezer: Up to 3 months in a sealed bag
Throw away any treats that smell off, feel slimy, or show signs of mold.
Helpful Tips for Shih Tzu Owners
- Keep a food journal. Note what your dog eats and how they react. Patterns show up quickly this way.
- Change one thing at a time. Introducing several new foods at once makes it hard to find the culprit.
- Choose soft, small pieces. Shih Tzus have short muzzles and small mouths, so oversized or very hard treats can be a struggle to chew.
- Keep fresh water available. Fiber works best when your dog is well hydrated.
- Talk to your vet. Especially if your dog has allergies, pancreatitis, or any chronic condition.
Frequently Asked Questions
Can Shih Tzu puppies eat these treats?
Many puppies can have small amounts, but their digestion is more delicate. Check with your vet before offering new foods to a young puppy.
Can I skip the egg?
Yes. Replace it with two extra tablespoons of pumpkin or applesauce.
Are oats safe for dogs with grain sensitivities?
Oats are usually well tolerated, but any grain can cause problems for some dogs. If you suspect a grain allergy, ask your vet before feeding oats.
How do I know if a treat is upsetting my dog’s stomach?
Watch for gas, loose stools, vomiting, scratching, or loss of appetite within a day or so of trying a new treat. Stop feeding it and call your vet if symptoms continue.
Final Thoughts
A sensitive stomach doesn’t mean your Shih Tzu has to miss out on treat time. With a short ingredient list, tiny portions, and a slow introduction, homemade treats can be a safe, enjoyable part of your dog’s day. Start small, watch how your dog responds, and adjust from there.
