For a dog with an upset stomach and vomiting, only very mild home care is safe to try, and you should be ready to call a vet quickly if things don’t improve or look at all serious.

First: When you MUST call the vet

Do not delay professional care if you notice any of these:

  • Vomiting many times in a row or lasting more than 12–24 hours.
  • Blood in vomit or stool, black/tarry stool, or coffee‑ground material.
  • Your dog is a puppy, senior, very small breed, pregnant, or has other illnesses (kidney, liver, diabetes, etc.).
  • Severe lethargy, collapse, pale gums, belly looks swollen or painful, or signs of poisoning (chewed medicine bottle, garbage, toxins).
  • They can’t keep water down at all, or seem dehydrated (sticky gums, sunken eyes, no urine).

If you’re unsure, treat it as urgent and call a vet or emergency clinic; they can often triage by phone.

What you can safely give at home (mild cases only)

These ideas are for an otherwise healthy dog with mild tummy upset, who is still fairly bright and can drink small amounts of water. Always introduce changes slowly.

1. Short “rest” for the stomach

  • Many vets recommend withholding food for about 6–12 hours (sometimes up to 24 hours in a healthy adult) to let the gut settle, as long as your vet has said fasting is safe for your dog’s age and health.
  • Do NOT withhold water entirely; instead, offer very small amounts at a time (a few sips every 15–30 minutes) so they don’t chug and vomit again.

If vomiting continues even with this gentle approach, you need a vet.

2. Bland diet options

Once vomiting has stopped for several hours and your dog can hold down water, you can offer a bland, easily digestible meal in tiny portions.

Safe bland foods commonly recommended by vets and pet‑health sources:

  • Plain boiled chicken (skinless, boneless, no fat, seasoning, onion, or garlic).
  • Plain white rice, well‑cooked, no salt, butter, or seasoning.
  • Plain boiled turkey or very lean hamburger, drained of fat, also unseasoned.
  • Plain canned pumpkin (100% pumpkin, not pie filling) in small spoonfuls; the fiber can help firm or normalize stool.
  • Low‑sodium, unseasoned bone broth (no onion/garlic) for extra hydration and gentle calories.
  • Some vets also allow a little plain yogurt with live cultures for gut bacteria in certain dogs, if they tolerate dairy.

How to feed:

  • Start with 1–2 teaspoons for tiny dogs or 1–2 tablespoons for medium/large dogs.
  • Offer this small amount every 2–3 hours, increasing slowly if they keep everything down.
  • If they do well for a day or two, gradually mix their regular food back in over 2–3 days.

3. Hydration and gentle fluids

Vomiting dries dogs out quickly, so careful hydration matters.

  • Fresh water, in frequent small sips, not a full bowl gulped at once.
  • Ice chips to lick if they keep vomiting after drinking; this sometimes stays down better.
  • Dog‑specific electrolyte solutions (from a vet or pet store) can help in mild cases if your vet approves.
  • Some vets allow small amounts of unflavored Pedialyte for dogs, but this should be done only under veterinary guidance because the wrong amount can be harmful.

If you see worsening thirst with minimal urine, or they cannot keep any fluid down, treat it as urgent.

Medicines: what NOT to give without a vet

  • Human meds like Pepto‑Bismol, Imodium, or others can be dangerous or hide serious disease and should not be given without specific veterinary dosing guidance.
  • Even when some products are technically used in dogs, they can interfere with tests, cause toxicity, or be unsafe with certain conditions or other meds.

A vet may prescribe:

  • Anti‑nausea medications such as maropitant (Cerenia), ondansetron, or metoclopramide, tailored to your dog’s weight and cause of vomiting.
  • Gut‑protective medications or fluids (possibly by injection or under the skin) if dehydration is a concern.

These are prescription treatments and are much safer than guessing with human OTC products.

Red‑flag causes you can’t treat at home

Because vomiting is a symptom, not a diagnosis, keep in mind some dangerous possibilities that need in‑clinic testing and treatment:

  • Foreign body (toy, bone, sock) stuck in the stomach or intestines.
  • Pancreatitis, especially in dogs that recently ate fatty foods.
  • Infections (parvovirus in puppies, severe gastroenteritis, etc.).
  • Toxins (chocolate, xylitol, grapes/raisins, medicines, chemicals).
  • Bloat (GDV) in large deep‑chested dogs – emergency.
  • Kidney, liver, or endocrine disease.

Because of this, home care is only for mild, short‑term cases in otherwise stable dogs.

Quick checklist: what to do right now

  1. Check your dog’s overall state: bright vs. weak, any blood, known toxin exposure, belly pain or swelling. If any concern, call a vet immediately.
  2. If they seem otherwise okay and your vet has previously said fasting is safe for your dog, offer a short break from food (6–12 hours), but not from small sips of water.
  3. Once vomiting settles, start tiny, frequent meals of bland food (boiled chicken and rice, a bit of pumpkin, etc.), slowly increasing as tolerated.
  1. Monitor closely for 24 hours. If vomiting continues, appetite doesn’t return, diarrhea becomes severe, or your gut feeling says “this is bad,” seek veterinary care promptly.

Bottom line: “What to give dog with upset stomach vomiting” is mostly about gentle bland food, careful hydration, and knowing when to stop home treatment and see a professional.
