What Can I Give My Dog for Vomiting and Nausea?
By Dr. Zubair Khalid, DVM, MS, PhD ·
If your dog just vomited once and seems fine, you can usually hold food for a short time, keep water available, and watch closely. If vomiting repeats, lasts more than a day, or comes with lethargy, pain, or blood, call your veterinarian. There is no single safe over-the-counter answer to what can I give my dog for vomiting, because the right treatment depends on the cause.

Quick Answer
- Withhold food but not water for about 12 hours after an isolated vomit, then offer small amounts of plain white rice and boiled chicken for two days [1].
- Do not give human nausea drugs, pain relievers, or motion sickness pills unless your veterinarian tells you to and gives you the dose.
- Call your vet if vomiting lasts more than 24 hours, if your dog seems lethargic, if the belly is painful, or if there is a fever [1].
- Go to an emergency clinic now if you see blood or material that looks like coffee grounds in the vomit [1].
- Prescription antiemetics such as maropitant (Cerenia), ondansetron (Zofran), and famotidine (Pepcid AC) are options your veterinarian may consider after an exam [1].
What Dog Vomiting and Nausea Look Like
Vomiting is the forceful ejection of stomach and upper small intestine contents. It usually comes after signs of nausea, including drooling, retching, and strong contractions of the belly and diaphragm [2].
That word "forceful" matters. Vomiting is active. Your dog will heave, arch the back, and push the food out. Regurgitation is different. It is passive, takes no effort, and the food often comes up undigested, sometimes in a tube shape that matches the esophagus. Coughing or trouble breathing show up more with regurgitation than with vomiting [2].
Nausea is harder to spot than vomiting. Watch for lip licking, swallowing, drooling, and a dog that turns away from food it normally loves. Some dogs pace or seem restless before they vomit.
One throw-up after eating grass is often a one-time event. Vomiting even once a week can point to a disease that needs a workup [1].
Common Causes of Vomiting in Dogs
Vomiting has many possible causes. They include digestive system disease, kidney or liver failure, pancreatitis, nervous system disorders, and eating irritating substances or poisons [2].
| Cause | Typical clues | How urgent |
|---|---|---|
| Dietary upset (new food, table scraps, garbage) | Vomits once or a few times, still bright and drinking | Monitor at home, call vet if it continues |
| Eating grass or a mild irritant | Single episode, dog returns to normal quickly | Usually an isolated incident [1] |
| Foreign object or toxin | Repeated vomiting, drooling, possible diarrhea, known access to a hazard | Emergency now |
| Pancreatitis | Vomiting with a painful belly, hunched posture, not eating | Same day |
| Kidney or liver failure | Long-term or repeated vomiting, weight loss, weakness, dehydration | Same day to urgent |
| Nervous system disorder | Vomiting with wobbliness, head tilt, or behavior change | Emergency now |
| Infection or inflammatory bowel disease | Vomiting that keeps coming back over days or weeks | Routine visit soon |
Short-term or occasional vomiting usually comes with no other problems. Long-term or repeated vomiting can bring weakness, lethargy, weight loss, dehydration, and electrolyte (salt) imbalance [2]. That is why duration matters as much as frequency.
Red Flags That Mean Emergency
Some signs mean you should not wait and see.
- Blood in the vomit, or material with the consistency of coffee grounds (digested blood) [1]
- Vomiting for more than 24 hours [1]
- Lethargy [1]
- A painful belly [1]
- A fever [1]
Unresolved vomiting can change electrolyte balance, which is needed for normal cell function, and can lead to life-threatening dehydration [1].
If your dog may have eaten something poisonous or a foreign object, call your veterinarian or a pet poison hotline right away. Do not try to make your dog vomit on your own. Inducing vomiting is a medical procedure, and in dogs it is most often done with an injected drug under veterinary supervision [3].

Safe Things You Can Do at Home While You Wait
Fasting and reintroducing food
For an isolated case of vomiting, you can withhold food but not water for 12 hours. After that, feed your dog plain white rice and boiled chicken for two days [1]. Keep portions small and frequent instead of one large meal.
Do not fast a puppy, a very small dog, or a dog with a health condition without asking your vet first. Young and tiny dogs can drop their blood sugar fast.
Water and hydration
Offer small amounts of water often. Ice chips can help a dog that gulps. Watch for dehydration signs like tacky gums, skin that stays tented when you pinch it, and sunken eyes. A dog that cannot keep water down needs to be seen.
What not to give
Do not reach into your own medicine cabinet. Human anti-nausea drugs, motion sickness pills, and pain relievers are not automatically safe for dogs, and the dose depends on weight and health. Your veterinarian calculates the dose from your pet's weight and condition.
Do not give food or treats that could make things worse, such as greasy table scraps, bones, or rich food. Do not force your dog to eat.
Keep notes
Write down when each vomit happened, what it looked like, whether food or bile came up, and whether your dog is drinking, urinating, and acting normal. These details help your vet decide how urgent the problem is.

Dog Medicine for Nausea and Vomiting
There is no one-size-fits-all answer here. Whenever possible, vomiting is controlled by finding and removing the cause while giving the digestive system time to recover [2]. That means the first job is diagnosis, not a pill.
When your veterinarian decides medication is appropriate, common prescription options include:
- Maropitant (Cerenia). A prescription antiemetic your vet may suggest after an exam [1]. In one randomized, blinded trial of healthy dogs, maropitant was given at 1 mg/kg subcutaneously to test its effect on nausea and vomiting before sedation [4]. That dose came from a specific study setting, so your vet will set the dose for your dog.
- Ondansetron (Zofran). Another prescription antiemetic your vet may suggest [1]. If you have heard about this drug, read Can You Give Your Dog Zofran for Vomiting? before giving anything at home.
- Famotidine (Pepcid AC). Sometimes suggested by veterinarians [1]. It is not a cure for every cause of vomiting, and it is not right for every dog.
- Dimenhydrinate. In one randomized, blinded trial, dimenhydrinate was given to healthy dogs at 4 mg/kg intramuscularly to test whether it prevented nausea and vomiting before sedation [4]. This was a study dose in a specific setting, not a home dose. Do not copy it.
A drug that stops vomiting can also hide a serious problem. If your dog has a blockage, a toxin, or pancreatitis, covering up the vomiting without treating the cause can delay care.
What Your Veterinarian Will Check and Test
Your vet starts with the story. When did the vomiting start? How many times? What does it look like? Any possible exposure to garbage, toys, plants, or medication?
Then comes the physical exam. Your vet will check hydration, gum color, belly pain, temperature, and heart rate. They will also look for signs that point to regurgitation instead of vomiting, since the two have different causes [2].
Depending on what they find, testing may include blood work, urine testing, X-rays, ultrasound, or a fecal exam. The goal is to sort out simple dietary upset from kidney or liver failure, pancreatitis, a foreign object, or a nervous system problem [2].
Treatment depends on the cause. It may include fluids for dehydration, antiemetics, a bland diet, or procedures to remove a foreign object. Some dogs need to stay for monitoring.
How To Treat Dog Nausea at Home and Prevent Repeat Episodes
Prevention starts with routine.
- Keep garbage, compost, medications, and small objects out of reach.
- Change foods slowly over several days instead of switching overnight.
- Skip table scraps and greasy food.
- Keep up with parasite prevention and routine wellness visits.
- Watch for patterns. Vomiting once a week or more can signal disease [1].
If your dog has a known sensitive stomach, ask your vet about a feeding plan before the next episode happens. Having a plan in place makes a middle-of-the-night vomit much less scary.
Limitations and When to Contact a Veterinarian
This article cannot tell you what is wrong with your dog. Individual cases need a veterinarian who can examine your pet, ask questions, and run tests.
Call an emergency clinic now if you see:
- Blood or coffee-ground material in the vomit [1]
- A painful belly [1]
- A fever [1]
- Lethargy [1]
- Vomiting that will not stop, or a dog that cannot keep water down
- Any known or suspected poisoning or swallowed object
Call your veterinarian the same day if:
- Vomiting has lasted more than 24 hours [1]
- Your dog is vomiting repeatedly but still seems somewhat alert
- Your dog is a puppy, a senior, or has a chronic illness
- You are unsure whether the vomit contains blood
Schedule a routine visit if:
- Vomiting happens once a week or more [1]
- Your dog is losing weight or eating less
- Vomiting comes and goes over weeks
Frequently Asked Questions
Can I give my dog human anti-nausea medicine?
No, not without veterinary guidance. Some human drugs are used in dogs, but the dose depends on weight and health, and some can be harmful. Your veterinarian will decide whether a prescription antiemetic is right and calculate the dose for your dog.
Should I fast my dog after vomiting?
For an isolated case, you can withhold food but not water for 12 hours, then feed plain white rice and boiled chicken for two days [1]. Skip fasting for puppies, tiny dogs, and dogs with health conditions unless your vet says otherwise.
What if my dog vomits once and acts completely normal?
A single episode, especially after eating grass, is often an isolated incident [1]. Offer water, hold food briefly, then reintroduce a bland diet. If it happens again, or if your dog seems off, call your vet.
Can I give my dog Pepto-Bismol or motion sickness pills?
Do not give these on your own. They are not automatically safe for dogs, and the correct dose is not something you can guess from a human label. Ask your veterinarian first.
How long can a dog go without eating after vomiting?
A short fast of about 12 hours is often enough for a mild, isolated episode [1]. If your dog refuses food after that, or vomiting returns when you feed, that is a reason to call your vet instead of extend the fast.
