How to Feed a Dog with an Upset Stomach

An upset stomach is one of the most common reasons dogs visit the vet — and one of the most manageable at home when caught early. Whether your dog is dealing with vomiting, diarrhea, gas, or just seems "off," adjusting their diet is the first and most important step. Here's what to feed a dog with an upset stomach and how to help them recover quickly.

Signs Your Dog Has an Upset Stomach

• Vomiting (once or twice, not repeatedly)
• Loose stools or diarrhea
• Excessive gas or bloating
• Gurgling stomach sounds
• Grass-eating (a classic self-soothing behavior)
• Reduced appetite or lethargy

If symptoms are severe, persistent, or accompanied by blood, contact your vet immediately.

Withhold Food Briefly First

For adult dogs with mild GI upset, a short fast of 12–24 hours can give the digestive system a chance to reset. Always provide fresh water during this time. Do not fast puppies, small breeds, or diabetic dogs without vet guidance.

Introduce a Bland Diet

After the brief fast (or immediately for puppies and small dogs), introduce a bland diet in small amounts:

• Boiled chicken breast — plain, no skin, no seasoning
• Plain white rice — well-cooked and soft
• Plain canned pumpkin — not pie filling, just pure pumpkin

Offer small portions every 3–4 hours rather than one large meal. This reduces the load on an already-irritated digestive system.

Why Pumpkin Works So Well

Plain pumpkin is a go-to remedy for dog digestive issues because it works for both diarrhea and constipation. The soluble fiber in pumpkin absorbs excess water in the intestines (helping with loose stools) while also adding bulk that keeps things moving (helping with constipation).

Add 1–4 tablespoons to your dog's bland meal depending on their size. Nummy Tum Tum Organic Pumpkin is a convenient pantry staple — 100% pure pumpkin, no additives, easy to portion out from the can.

Keep Them Hydrated

Vomiting and diarrhea both cause fluid loss. Make sure your dog has constant access to fresh water. If they're reluctant to drink, try offering a small amount of low-sodium broth or a bone broth topper to encourage fluid intake.

The Honest Kitchen Bone Broth Pour Overs are a great way to add both hydration and gentle nutrition when your dog's stomach is sensitive. The liquid format is easy to digest and the savory flavor encourages drinking.

Transitioning Back to Regular Food

Once your dog has had 24–48 hours of solid bland diet with no symptoms, begin mixing in their regular food gradually:

• Day 1–2: 75% bland, 25% regular food
• Day 3–4: 50/50 mix
• Day 5–6: 25% bland, 75% regular food
• Day 7: Back to normal

What to Avoid

• Fatty or greasy foods
• Dairy products
• Spicy or heavily seasoned food
• Raw food during active GI upset
• Large meals

Final Thoughts

Most mild upset stomachs in dogs resolve within 24–48 hours with a bland diet and good hydration. The key is to keep things simple, gentle, and consistent. If symptoms persist beyond 48 hours or worsen at any point, your vet is the next call.
