Quick answer: For a mild upset stomach in a bright adult dog, vets often suggest a short food rest, small sips of water, then small portions of a bland diet such as plain boiled chicken and rice, with a slow return to normal food. Skip human medications unless your vet says so, and call if vomiting repeats.
When your dog is gagging, gulping grass, or turning down dinner, you want to help right now. The good news is that many mild upsets settle within a day. The better news is that the safest steps are simple. This guide covers what vets commonly suggest, what to skip, and the signs that mean it is time to stop home care and call.
Call your vet now if your dog has any of these
- Vomit or stool that contains blood, or vomit that looks like coffee grounds
- Vomiting more than once or twice in a day, or vomiting that keeps returning over several days
- Lethargy, weakness, collapse, fever, or belly pain
- A swollen, tight belly, drooling, or unproductive retching (trying to vomit and nothing comes up)
- Diarrhea along with vomiting, or signs of dehydration such as dry, sticky gums
- A puppy, a senior dog, a toy breed, or a dog with a health condition such as diabetes, kidney disease, or heart disease
- Any chance your dog swallowed a toy, sock, bone, plant, medication, or something toxic
If you think your dog ate something poisonous, call your vet or the ASPCA Animal Poison Control Center right away. When in doubt, call.
What an upset stomach usually looks like
"Upset stomach" is a catch-all phrase, not a diagnosis. In dogs it often shows up as one or more of these signs: drooling or lip licking, restlessness, eating grass, gurgling belly sounds, a lower appetite, vomiting, or loose stool. The VCA Animal Hospitals overview of vomiting in dogs notes that vomiting is a sign, not a disease, and that occasional vomiting in an otherwise healthy dog may not mean anything is wrong. It also says many sudden cases improve on their own within 24 hours.
Common mild triggers include eating table scraps or garbage, a quick switch in food, a rich treat, stress, and intestinal parasites. More serious causes include infections, pancreatitis, toxins, blockages, and kidney or liver disease. That is why the red-flag list matters more than any home remedy.
Step 1: Check the situation before you feed anything
Before you reach for the pantry, ask three quick questions. Is my dog bright and alert? Has the vomiting happened once or twice at most? Could my dog have swallowed something harmful? If your dog is lively, the episode was brief, and a swallowed object or toxin is unlikely, home care is reasonable. If any answer worries you, phone your vet first.
Step 2: Water and a short food rest
Offer fresh water in small amounts, a few laps at a time, because a big gulp can set off more vomiting. The Merck Veterinary Manual states plainly that water should not be withheld from a vomiting dog unless the dog is getting fluids from a vet, because dehydration makes things worse.
For food, vets often suggest a brief rest while the stomach calms down. The length varies by source and by dog. Merck describes withholding food for about 24 hours in a vet-directed plan, while the American Kennel Club cites a much shorter pause of one to two hours for a mild case, then small amounts of water and bland food if things stay calm. Because the right amount differs, ask your vet how long to rest your dog.
Who should not fast: puppies, toy and small breeds, senior dogs, and dogs with diabetes or other health conditions can run into trouble without regular meals. Call your vet before skipping food for any of them.
Step 3: A vet-approved bland diet
Once the vomiting has stopped and your dog seems comfortable, the next step many vets suggest is a bland, easily digested diet. VCA says your vet may recommend a specific home-cooked diet fed in small portions given frequently, with no other foods during that time. The AKC lists boiled, skinless, boneless chicken breast as a gentle option, and its diarrhea guidance describes boiled chicken and rice as an at-home approach for mild cases.
A simple version looks like this:
- Cook plain. Boil skinless, boneless chicken breast and plain white rice. No oil, butter, salt, onion, garlic, or seasoning.
- Serve small portions. Offer a few spoonfuls at a time, then wait. The right amount depends on your dog's size, so ask your vet for portions.
- Feed little and often. Several small meals are easier on a sensitive stomach than one big one.
- Watch your dog. If your dog keeps it down and acts normally, you can slowly offer a bit more.
- Return to normal food gradually. VCA describes increasing portions and slowly reintroducing the regular diet over several days. For diarrhea cases, VCA mentions a transition of seven to ten days. Mixing a little of the regular food into the bland meal, then increasing it day by day, is a common way to do this.
A bland diet is a short-term plan, not a complete diet. If your dog needs it for more than a few days, your vet should be involved, because long-term home cooking can leave out important nutrients.
Things not to give
- Human medications. Pain relievers, anti-nausea products, antacids, and anti-diarrheal products made for people can be ineffective or harmful for dogs, and dog doses are different. The AKC quotes an emergency veterinarian who urges owners not to use human medications for a dog's diarrhea because "most human medications are ineffective, but some can be harmful." Talk to your vet before giving any human medication.
- Fatty, greasy, or seasoned scraps. Rich food can irritate the gut, and fatty meals are a known concern for pancreatitis.
- Milk and dairy. The ASPCA notes that pets lack much lactase, so dairy can cause diarrhea or other digestive upset.
- Toxic foods. Grapes, raisins, chocolate, onions, and garlic are dangerous. The ASPCA list of people foods to avoid is worth bookmarking.
Remedies people ask about
Plain pumpkin. The AKC lists puréed pumpkin among the gentle, bland foods that may help soothe an upset stomach in mild cases. Use plain pumpkin, not pie filling, which contains sugar and spices, and ask your vet about an amount for your dog.
Ginger, bone broth, and other kitchen remedies. We could not find solid veterinary guidance for these in the sources we trust, so we are not recommending them. Some broths contain onion, garlic, or lots of salt, which are not good for dogs. If you want to try something beyond a bland diet, ask your vet first.
Where a daily probiotic may fit
A probiotic is not a remedy for an upset stomach in the moment, and it will not treat the cause of vomiting. But after your vet has ruled out anything serious, some owners look for ways to support their dog's everyday digestive health, and that is where a daily probiotic may fit. VCA mentions that several probiotic products may help dogs with diarrhea, while also telling owners to consult their vet first because the quality and effectiveness of these products are not always known. Published trials have looked at probiotic use in dogs with acute diarrhea, and a canine-specific probiotic product has been studied in dogs with acute or intermittent diarrhea. Research on vomiting itself is thinner, so we will not promise more than that.
Probonix for Dogs is a liquid probiotic with 8 strains that goes right on your dog's food, 6 drops a day for small dogs and 8 drops for medium and large dogs. It can help maintain healthy digestion as part of a routine your vet is comfortable with. It is a dietary supplement, not a medicine, and is not meant to diagnose, treat, cure, or prevent any disease.

Frequently asked questions
Can I give my dog Pepto-Bismol for an upset stomach?
Do not give it unless your vet tells you to. Human stomach medications can be ineffective or unsafe for dogs, and the right dose depends on your dog's size and health. Call your vet and ask what is safe.
How long should a dog eat chicken and rice?
Usually just a few days, then a gradual return to regular food over several days. If your dog is not improving, or needs the bland diet for longer than your vet suggested, schedule a visit.
Should I fast my dog after vomiting?
A short food rest is common advice for healthy adult dogs, but the length varies and some dogs should not fast at all, including puppies, small breeds, seniors, and diabetic dogs. Ask your vet what fits your dog. Keep fresh water available unless your vet says otherwise.
Is pumpkin good for a dog's upset stomach?
Plain puréed pumpkin is listed by the AKC as a gentle food for mild cases. Avoid pumpkin pie filling, and check with your vet about how much your dog should have.
When is an upset stomach an emergency?
Go to your vet or an emergency clinic if there is blood, repeated vomiting, a swollen belly, weakness, unproductive retching, or any chance your dog swallowed an object or toxin. Puppies and seniors can decline quickly, so call sooner.
