# Dog Throwing Up: Medicines and Remedies That Help Vomiting in dogs is common, and most short episodes pass without treatment. When it does not stop, the right dog medicine for throwing up is usually a prescription anti-nausea drug chosen by a veterinarian, not something from your own medicine cabinet. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Occasional vomiting in an otherwise bright, drinking dog is often minor and can be watched for a short time [1]. - Never give human anti-nausea or pain drugs without veterinary direction. Some are toxic to dogs, and doses are calculated by weight. - Prescription anti-nausea medicines such as maropitant and metoclopramide are the standard treatments vets use for vomiting. - Blood in vomit, a bloated belly, repeated unproductive retching, or vomiting with fever, collapse, or a known toxin exposure means go to a vet now. - Withholding food for a day is not always right, especially in puppies, small dogs, and dogs on daily medication. ## What Dog Vomiting Looks Like and What Is Normal Vomiting is the forceful ejection of stomach and upper small intestine contents [1]. It usually comes with warning signs first, such as nausea, heavy drooling, retching, and hard contractions of the belly and diaphragm [1]. Your dog may lick their lips, swallow repeatedly, or pace before anything comes up. This is different from regurgitation, which is passive and takes no effort [1]. Regurgitated food often looks undigested and may keep a tube shape from the esophagus, and it is more often linked to coughing or trouble breathing than to nausea [1]. Short-term or occasional vomiting is generally not tied to other problems [1]. Long-term or repeated vomiting can bring weakness, lethargy, weight loss, dehydration, and electrolyte imbalance [1]. That is the line that matters most. One vomit and a happy dog is a very different situation from six vomits in an afternoon with a dog who will not stand up. ## Main Causes of Vomiting in Dogs Vomiting is a sign, not a disease. It can come from digestive system disease, kidney or liver failure, pancreatitis, nervous system disorders, and eating irritating substances or poisons [1]. Because the list is long, the clues around the vomiting matter as much as the vomiting itself. | Cause | Typical clues | How urgent | |---|---|---| | Dietary upset (new food, garbage, table scraps) | One or two vomits, still playful, normal gum color | Usually minor, watch closely | | Stomach or intestinal disease | Repeated vomiting, not eating, belly pain, diarrhea | See a vet soon | | Pancreatitis | Vomiting with a hunched posture, belly pain, lethargy | Same day | | Kidney or liver failure | Vomiting with weight loss, drinking more, bad breath | Same day | | Nervous system disorder | Vomiting with wobbliness, head tilt, seizures | Emergency now | | Poison or irritating substance | Vomiting after chewing a plant, pill, or chemical | Emergency now | | Foreign object (bone, skewer, toy) | Vomiting, drooling, retching, not passing stool | Emergency now | Foreign objects deserve special mention. In a study of 114 dogs that swallowed a skewer or popsicle stick, vomiting was induced successfully in 38 of 48 dogs, but the rest needed endoscopy or surgery [2]. That is why you should never try to make your dog vomit at home. The decision depends on what was swallowed, how long ago, and whether it is safe to bring back up. Some dogs have chronic, pattern-based vomiting. A 16-year-old Maltese with daily vomiting that did not respond to maropitant, ondansetron, or metoclopramide was eventually diagnosed with a syndrome resembling cyclic vomiting syndrome, the first report of its kind in dogs [3]. This is rare, but it shows that vomiting which resists standard anti-nausea drugs needs a deeper workup, not stronger home remedies. ## Dog Medicine for Upset Stomach and Vomiting: What Vets Actually Use ### Prescription anti-nausea drugs Maropitant is one of the most used anti-nausea drugs in dogs. In a blinded trial of 87 healthy dogs, maropitant at 1 mg/kg given under the skin 60 minutes before sedation reduced nausea and vomiting compared with placebo [4]. The same study found that injection-site discomfort was more common in the maropitant group [4]. Your vet calculates the dose from your dog's weight and health, and the drug comes as an injection or an oral tablet. Metoclopramide and ondansetron are other anti-nausea options. They work through different pathways, which is why a dog who does not respond to one may respond to another. Ondansetron targets the serotonin system, and that system does not cover every type of nausea [5]. Dimenhydrinate, an over-the-counter antihistamine used for motion sickness in people, was also tested in that same 87-dog trial at 4 mg/kg given into the muscle [4]. It is not a first-choice drug for general vomiting, and you should not dose it at home without a vet's instruction. ### What about human medicines? Do not reach for your own stash. Human anti-nausea drugs, pain relievers, and stomach acid pills are dosed for people, and some are outright toxic to dogs. Even when a drug is used in dogs, the dose depends on weight, other medications, kidney and liver function, and what is causing the vomiting. A veterinarian has to make that call. If your dog vomits after you give a prescribed or over-the-counter medication, that is a separate problem with its own steps. See [Why Is My Dog Throwing Up After Taking Medicine?](/knowledge/veterinary-medicine/pet-medication-guide/dog-throwing-up-after-medicine) and [What to Do If Your Dog's Medication Is Causing Vomiting: Home Care and When to Worry](/knowledge/veterinary-medicine/pet-medication-guide/dog-medication-vomiting-home-care). ### Why fasting advice can be wrong The old advice to pull food and water for 24 hours is not a universal rule. Vets control vomiting by finding and removing the cause while giving the digestive system time to recover [1]. That recovery plan looks different for a healthy adult dog with one vomit and for a diabetic dog, a puppy, or a dog on seizure medication. Skipping meals can cause its own problems in those groups. Ask your vet before you withhold food, and never withhold water from a dog who is vomiting and thirsty unless a vet tells you to. ## Dog Throwing Up and Diarrhea: What Changes When vomiting comes with diarrhea, the risk of dehydration climbs fast. Fluid loss from both ends can drop a dog quickly, especially small breeds and puppies. This combination also raises the odds of a contagious or dietary cause, and it makes home monitoring harder because you cannot easily judge fluid balance by eye. If your dog has both signs and is still bright and drinking, call your vet for guidance the same day. If your dog is dull, has a dry mouth, or will not drink, treat it as urgent. For home steps that are safe to try while you wait, see [Dog Throwing Up And Diarrhea Home Remedy](/knowledge/veterinary-medicine/symptom-guides/dog-throwing-up-and-diarrhea-home-remedy). ## Dog Medicine for Fever and Vomiting Fever with vomiting points away from a simple dietary upset. It suggests infection, inflammation, or a systemic problem, and it needs a veterinary exam instead of a home remedy. Do not give human fever reducers such as acetaminophen or ibuprofen. They are not safe for dogs, and the dose cannot be guessed. A dog with a fever may feel warm to the touch, shiver, breathe fast, or seem stiff and sore. Take the temperature only if you have a rectal thermometer and your dog tolerates it, and stop if it causes distress. Then call your vet and describe both signs together. Fever plus vomiting is a same-day visit at minimum. ## Red Flags That Make It an Emergency Go to a veterinarian now, not later, if you see any of these: - Repeated unproductive retching with a swollen belly (possible bloat) - Blood in the vomit, or vomit that looks like coffee grounds - Vomiting after eating a known poison, human medication, or foreign object - A distended, painful, or hard belly - Collapse, weakness, pale gums, or trouble breathing - Vomiting with a fever, seizures, head tilt, or wobbliness - Vomiting in a puppy, a senior dog, or a dog with a chronic illness - Vomiting that will not stop for more than a few hours, or any vomiting with a dog who cannot keep water down Long-term or repeated vomiting is linked to weakness, lethargy, weight loss, dehydration, and electrolyte imbalance [1]. Those changes can become serious before you notice them at home. ## Safe Things You Can Do at Home While You Wait You cannot treat vomiting at home with medicine, but you can keep your dog safe and give your vet useful information. - Remove food and water bowls only if your vet tells you to. Otherwise, offer small amounts of water often. - Write down the time of each vomit, what it looked like, and whether food, bile, blood, or a foreign object was in it. - Check your dog's gums. Pink and moist is normal. Pale, white, blue, or tacky gums mean call the vet now. - Keep your dog away from garbage, compost, and any chewed-up items so they cannot eat more. - Do not give human drugs, herbal remedies, or leftover pet prescriptions. - Do not try to make your dog vomit. Emesis should only be induced by a veterinarian who knows what was swallowed. If your dog is on a daily medication and vomits it up, do not give a second dose on your own. Call your vet or the prescribing clinic for instructions. Repeated vomiting of medication can mean the drug is not being absorbed, and that matters for conditions like epilepsy or heart disease. ## What Your Veterinarian Will Check and Test Your vet starts with the story. When did it start, how many times, what did it look like, is your dog eating and drinking, any diarrhea, any possible exposure to toxins or objects. Then comes a full physical exam, including belly palpation, hydration check, gum color, and temperature. Testing depends on what the exam suggests. Common steps include blood work to check organ function and electrolytes, a stool check, and imaging such as X-rays or ultrasound if a foreign object or blockage is possible. In complex cases, vets may use contrast studies, endoscopy with biopsy, or advanced imaging to rule out structural causes [3]. Treatment is built around the cause. If nausea is the main problem, your vet may give an injectable anti-nausea drug and send you home with an oral version. If the cause is a toxin, a foreign object, or organ disease, the plan changes completely. Vomiting is controlled by removing the cause while the digestive system recovers [1]. ## Prevention and Monitoring Most repeat episodes can be reduced with a few habits. - Keep garbage, compost, bones, skewers, and small toys out of reach. Skewer and stick ingestion is common enough to have its own case series [2]. - Change foods slowly over several days instead of switching overnight. - Feed measured meals at set times, and skip table scraps if your dog is prone to stomach upset. - Store all human medications in closed cabinets. Dogs cannot tell your pills from treats. - Track episodes in a note on your phone. Patterns help your vet decide whether this is a one-time event or a chronic problem. - Keep routine wellness visits so kidney, liver, and metabolic problems get caught before vomiting starts. If your dog has had more than a couple of vomiting episodes in a month, or if episodes follow a pattern, bring the log to your vet. Pattern-based vomiting that resists standard anti-nausea drugs is uncommon but real, and it needs a full workup instead of repeated home treatment [3]. ## Limitations and When to Contact a Veterinarian This article cannot tell you what is causing your dog's vomiting. Only a veterinarian who examines your dog can do that, and individual cases need a veterinarian's judgment. Call your vet the same day if your dog has vomited more than twice, is not eating, has diarrhea along with vomiting, is on a daily medication, or is a puppy or senior. Go to an emergency clinic right away for a swollen belly, unproductive retching, blood in the vomit, collapse, pale gums, trouble breathing, a known toxin exposure, or vomiting with fever or neurologic signs. For a single mild vomit in a bright, drinking adult dog, a routine visit is reasonable if it happens again. ## Frequently Asked Questions ### Can I give my dog human anti-nausea medicine for vomiting? No, not without a veterinarian's direction. Human drugs are dosed for people, and some common ones are toxic to dogs. Even drugs that are used in dogs need a weight-based dose and a diagnosis first. ### What can I give my dog for throwing up at home? Nothing medicinal. Safe home steps are limited to offering small amounts of water, removing access to garbage and objects, and writing down the details of each episode. Any anti-nausea drug should come from your vet. ### Is it safe to fast my dog after vomiting? Not always. Vets control vomiting by treating the cause while letting the digestive system rest, and that plan varies by dog [1]. Puppies, small dogs, and dogs on daily medication may do worse with skipped meals, so ask your vet first. ### When should I worry about my dog throwing up? Worry when vomiting repeats, when your dog stops eating or drinking, or when you see blood, a swollen belly, collapse, fever, or neurologic signs. Long-term vomiting can lead to dehydration, weight loss, and electrolyte problems [1]. ### Can my dog's vomiting be caused by a swallowed object? Yes, and it is a common reason for vomiting. In one study of 114 dogs that swallowed a skewer or popsicle stick, vomiting was induced successfully in 38 of 48 dogs, while others needed endoscopy or surgery [2]. Never try to make your dog vomit at home. ## Related Articles - [Dog Vomiting: What Medicine Can You Give?
