What to feed a dog with an upset stomach

A bland diet can settle a mild tummy upset — but knowing when it's a vet job matters just as much. Here's the simple approach, and the red flags.

What to feed a dog with an upset stomach

For a mild, one-off tummy upset, a simple bland diet often helps a dog settle — but the first question isn't what to feed, it's whether this needs a vet at all. Get that right, and the feeding part is refreshingly simple.

Charlie
Charlie's tip

See your vet first if the upset is severe or persistent, if there's blood in the vomit or stool, or if your dog is a puppy, very small, elderly or has a health condition. Ongoing vomiting or diarrhea causes dehydration quickly, and some causes need treatment, not just a change of food.

The classic bland diet

Once your vet is happy it's a mild upset, the go-to is plain, easily digestible food: boiled skinless chicken or lean turkey with plain white rice, cooked with no salt, oil or seasoning. Serve it in small, frequent portions rather than one big meal, and make sure fresh water is always available. A spoonful of plain pumpkin can help firm things up, too.

Getting back to normal

As your dog improves over a day or two, reintroduce their usual food gradually — mixing a little more in each day — rather than switching straight back, which can restart the upset. A bland diet is a short-term bridge, not a long-term diet, because on its own it isn't complete and balanced.

Rule out the serious first, then keep it plain, small and frequent — and ease back to normal slowly.

If your dog isn't improving within a day or two, gets worse, or seems unwell in any other way, stop guessing and call your vet. And never give human stomach medicines without veterinary advice. Informational only — always consult your vet for dietary decisions.

Common questions

What can I feed my dog with an upset stomach?

For a mild upset, a bland diet of boiled plain chicken or lean turkey with plain white rice, in small frequent portions, is the classic choice. Check with your vet first, especially if symptoms are severe or persistent.

How long should a dog stay on a bland diet?

Usually just a couple of days, then a gradual return to their normal food. A bland diet isn't complete and balanced for the long term, so it's a short bridge, not a lasting diet.

When should I take my dog to the vet for an upset stomach?

If the upset is severe or ongoing, there's blood, or your dog is a puppy, elderly, very small or unwell in other ways. Persistent vomiting or diarrhea can cause dehydration and needs veterinary care.

Can I give my dog human anti-diarrhea medicine?

Not without veterinary advice. Some human medicines are unsafe for dogs or can mask a problem, so always ask your vet before giving anything.

Charlie's the guide. These two keep him busy.

Two dogs, two completely different problems, one rule: read the label first.

Charlie
Charlotte
Shih Tzu · 7.8 kg

Came off "premium" kibble after a single scan turned up coral. Six weeks of home-cooked turkey bowls later: less scratching, a coat you'd notice across a room.

Theodor
French Bulldog · 18.3 kg

A sensitive stomach and a drawer full of "maybe" treats. One quiet afternoon of scanning sorted the safe from the questionable for good.

The reveal

No black box. No scare tactics.

One scan turns any label into a single rating — mint for good, coral for caution. Here's the difference it surfaces, side by side.

The science

How the dog food score is built.

One number on a single scale, built from the label and weighed against vet-informed thresholds. No black box, no scare tactics.

One scale, four bands
0 → 100
CautionFairGoodExcellent

On the surface you see two colors — mint for good, coral for caution. The number underneath is what moves the badge, so two foods that both look "fine" still rank against each other on the same scale.

Four things move the number.

01
Ingredient order

What's listed first is what's mostly in the bag. A named whole protein up top lifts the score; corn or "meat meal" first pulls it down.

02
Risk flags

Fillers, artificial dyes, vague by-products and known irritants are checked against a vet-informed watchlist. Every flag is a deduction you can see.

03
Nutrient balance

Protein, fat, fiber and sodium are read against the range for your dog's size and life stage — not a one-size-fits-all average.

04
Transparency

Specific labels score better than vague ones. If a brand won't say what's actually in the bag, that uncertainty counts against the score, not for it.

A worked example

Same shelf. Two very different scores.

What these guides cover

01
Food safety

Can dogs eat this? Clear answers on everyday foods — with genuine hazards like chocolate, grapes and xylitol flagged firmly, and the rest kept in proportion.

02
Feeding & portions

How much to feed, how often, and why it changes with a dog's weight, age and activity — the same math the NatBuddy app runs per pet.

03
Homemade recipes

Simple, real-food recipes with actual nutrition numbers, weighed against AAFCO baselines — a starting point to cook from, not a prescription.

04
Labels & ingredients

What ingredient lists actually tell you, what the marketing hides, and how to read a bag before you trust it.

How these guides are made

Every article is grounded in published guidance from the ASPCA, AAFCO, the National Research Council (NRC) and WSAVA — and each one lists its sources at the bottom, so you can check them yourself instead of taking our word for it.

Health topics use cautious language on purpose. We flag real dangers clearly, but we won't scare you about a food that's simply worth a quick word with your vet. The scores in our reviews come from the same method the app uses — you can read it in full on The Science.
