What to feed a dog with an upset stomach
A mild, short-lived upset stomach in an otherwise well dog is often managed with a plain, easily digested diet for a short period, alongside your vet's advice — never as a substitute for getting your dog checked if things do not settle quickly or your dog seems genuinely unwell.
Why a bland diet is the usual approach
The idea behind a bland, easily digested diet is to give an irritated gut less work to do while it settles, rather than to treat whatever caused the upset in the first place. It is a supportive step, not a cure, which is why it is normally used for mild, short-term upsets rather than as a response to anything more serious or ongoing.
Reintroducing food gradually rather than going straight back to a normal portion of a dog's usual food also matters, since doing too much too soon can restart the same problem. Your vet is the right person to advise on timing for your specific dog.
What to look for in a suitable food
A food designed around digestive sensitivity typically uses a limited number of easily recognised ingredients, avoids some of the more common triggers, and is formulated to be gentle on a sensitive gut rather than rich or high in fat, which can make an upset stomach worse rather than better.
Reading the ingredients list matters more than the marketing on the front of the pack — look for a short, clear ingredients panel rather than a long list of additions, and check whether the food is specifically formulated for sensitivity rather than simply labelled as a standard adult recipe.
When it needs a vet, not just a diet change
See your vet if your dog's upset stomach lasts more than a day or two, if there is blood in the vomit or stool, if your dog seems lethargic, is repeatedly vomiting, has stopped drinking water, or is a puppy, an older dog, or has an existing health condition — all of which deteriorate faster than a healthy adult dog with a mild, short-lived upset.
A dog who is bright, still drinking, and only mildly off their food with one or two loose stools is generally less urgent, but ongoing or worsening symptoms of any kind are a reason to stop managing it at home and get them examined properly.
Supporting digestion going forward
For a dog with a genuinely sensitive stomach rather than a one-off upset, sticking to one consistent, appropriate food rather than switching often tends to help, since frequent changes are themselves a common trigger for digestive upset in dogs prone to it.
A digestive supplement can be worth discussing with your vet for a dog with recurring sensitivity, used alongside — never instead of — an appropriate diet and any advice specific to your dog's situation.

Common questions
- Can I just feed my dog chicken and rice for an upset stomach?
- A plain, bland approach along these lines is a commonly used short-term step for a mild upset, but it is not nutritionally complete for ongoing feeding and should not replace your dog's normal diet for more than a short period. Speak to your vet if you are not sure how long to continue it.
- How long should a bland diet last?
- This depends on your dog and how they respond, which is why it is best discussed with your vet rather than followed for a fixed number of days regardless of how your dog is doing. Reintroducing normal food too soon or too late can both cause problems.
- When should I worry about my dog's upset stomach?
- Worry, and see a vet, if it lasts more than a day or two, if there is blood in the vomit or stool, if your dog seems lethargic or stops drinking, or if they are a puppy, an older dog, or already have a health condition. These groups can deteriorate faster than a healthy adult dog.
- Is a sensitive stomach food the same as a bland diet?
- Not exactly. A bland short-term diet is usually a temporary step during an active upset, while a sensitive stomach food is a complete, balanced diet formulated for ongoing feeding in a dog prone to digestive sensitivity. Your vet can advise which is appropriate for your dog's situation.
