My Dog Keeps Throwing Up: What Can I Give Him?

Watching your dog throw up is stressful, especially when it happens repeatedly. Your instinct is to do something — anything — to make them feel better. But giving the wrong remedy, or waiting too long when the situation is serious, can turn a manageable stomach upset into a dangerous emergency.

The single most important rule is this: vomiting is a symptom, not a disease. It can be caused by something as harmless as eating grass too quickly or as serious as parvovirus, pancreatitis, or an intestinal obstruction. Your job is to assess the severity, provide safe supportive care for mild cases, and recognize when your dog needs a vet immediately. This guide gives you that framework.

Vomiting vs. Regurgitation: Know the Difference

Owners often use these terms interchangeably, but they point to different problems and different urgency levels. Knowing which one you are seeing helps your veterinarian narrow down the cause faster.

If your dog regurgitates but is otherwise bright and eating normally, the issue is more likely mechanical (such as swallowing too fast or an esophageal issue) and should still be checked by a vet if it recurs. Active vomiting with nausea is more often related to the stomach or intestines. For a deeper look at related digestive problems, see our guide on dogs who do not chew their food and then vomit.

Safe First Steps When Your Dog Is Throwing Up

When you have assessed that your dog is bright, alert, and otherwise acting normally, these are the safe first steps. Follow them in order.

1. Remove access to food temporarily. For healthy adult dogs, a food fast of 6-12 hours gives the digestive system time to settle. If your dog is a puppy under 6 months, a toy breed, or has a known health condition such as diabetes, do not fast without veterinary approval.
2. Keep fresh water available in small amounts. Do not let your dog gulp a large bowl of water at once, as this can trigger more vomiting. Offer a few tablespoons at a time, every 20-30 minutes. If your dog cannot keep water down, this is a red flag for dehydration and warrants a vet call.
3. Observe closely for warning signs. Check for lethargy, pale gums, a bloated or tense abdomen, shaking, drooling, or blood in the vomit. Any of these signals escalate the situation to an urgent vet visit.
4. Do not rush to reintroduce food. After the fast, start with a small amount of bland food only if your dog has not vomited during the fasting period. Small, frequent meals are better tolerated than one large meal.
5. Note the details. Write down how many times your dog vomited, what it looked like, whether it was food or foam or bile, and when it happened. This information is extremely helpful to your vet and can speed up diagnosis.

What You Can Safely Give Your Vomiting Dog

There is no safe human medication you can give for dog vomiting without veterinary approval. What you can safely offer is supportive care — hydration, rest, and a carefully managed bland diet. Here is what is generally considered safe for mild, uncomplicated vomiting.

Safe Supportive Options

• Small sips of fresh water. Hydration is more important than food. Offer small amounts frequently. If your dog refuses water entirely for more than 12 hours, call your vet.
• Ice chips. For dogs who gulp water too fast and trigger vomiting, ice chips can provide hydration more slowly.
• Plain boiled chicken breast. Skinless, boneless, unseasoned, and shredded into small pieces. This is a low-fat, highly digestible protein source that most dogs tolerate well.
• Plain white rice. Cooked thoroughly and served plain. White rice is easy to digest and helps bind loose stool if diarrhea is also present.
• Plain canned pumpkin. Pure pumpkin puree, not pie filling, in small amounts (about 1-2 teaspoons for small dogs, 1-2 tablespoons for large dogs). It provides soluble fiber and is soothing to the stomach.
• Plain boiled egg. Unseasoned and chopped, in small amounts. A gentle protein source for dogs who tolerate chicken well.
• Low-sodium, unseasoned chicken broth. A small amount can encourage drinking. Check the label carefully — it must contain no onions, garlic, or added salt. Homemade broth is safest.
• Plain cooked sweet potato. Mashed and unseasoned, in small amounts. A gentle source of fiber and carbohydrates.

What You Must Never Give Your Vomiting Dog

This section may be the most important part of this entire guide. Many well-meaning owners give human medications that cause serious harm. Never give any of the following without explicit instructions from your veterinarian.

• Pepto-Bismol (bismuth subsalicylate). Contains salicylates that can be toxic to dogs, especially cats and small dogs. It can cause gastrointestinal bleeding and, in high doses, neurological problems.
• Human anti-nausea medication. Drugs like Dramamine, promethazine, and metoclopramide are sometimes used in dogs but only under veterinary supervision. Wrong doses can cause dangerous side effects including seizures and heart arrhythmias.
• Ibuprofen, naproxen, or aspirin. Human NSAIDs are toxic to dogs and can cause kidney failure and stomach ulcers. This is one of the most common accidental poisonings in pets.
• Acetaminophen (paracetamol, Tylenol). Toxic to dogs even in small amounts and can cause liver damage and death.
• Human motion sickness tablets. Often contain ingredients unsafe for dogs, and dosing is impossible to calculate safely by eye.
• Milk or dairy products. Many dogs are lactose intolerant, and dairy can worsen vomiting and diarrhea.
• Fatty or greasy foods. Can trigger pancreatitis, a painful and potentially life-threatening condition. If your dog has vomiting and a history of pancreatitis, see our guide on managing dog pancreatitis.
• Any food containing onion, garlic, grapes, raisins, chocolate, xylitol, or macadamia nuts. All are toxic to dogs and can cause vomiting as an early symptom of poisoning.
• Human oral rehydration solutions. Some are high in sugar or contain ingredients not suitable for dogs. Ask your vet before using any electrolyte product.

Common Causes of Vomiting in Dogs

Understanding what might be causing the vomiting helps you decide how urgently to act. Causes range from harmless to life-threatening.

Mild, Self-Limiting Causes

• Dietary indiscretion. Eating garbage, table scraps, or something unusual. Often causes a single episode of vomiting followed by a quick recovery.
• Eating too fast. This is a common cause of regurgitation, especially in greedy eaters. Slow feeder bowls help. For more on fast eaters, see our guide on dogs that do not chew their food.
• Food transition. Switching foods too abruptly causes stomach upset. Always transition over 7-10 days by mixing old and new food gradually.
• Grass or plant eating. Some dogs vomit after eating grass. Usually harmless unless the plant is toxic. See our guide on toxic foods for dogs for what plants to keep away from.
• Motion sickness. Vomiting during car rides is common, especially in puppies. Ask your vet about safe anti-nausea options for travel.

Causes Requiring Veterinary Attention

• Parvovirus. A serious, often fatal viral infection in unvaccinated puppies. Symptoms include severe vomiting, bloody diarrhea, lethargy, and loss of appetite. If your puppy has these signs, seek emergency care immediately. See our guide on recognizing and managing parvo.
• Pancreatitis. Inflammation of the pancreas, often triggered by fatty foods. Causes repeated vomiting, abdominal pain, and lethargy. Requires veterinary treatment.
• Intestinal obstruction. A swallowed toy, bone, or foreign object blocks the intestine. Symptoms include repeated vomiting, refusal to eat, and abdominal pain. This is a surgical emergency.
• Gastric dilatation-volvulus (bloat). A life-threatening condition where the stomach fills with gas and twists. Symptoms include a distended abdomen, retching without producing vomit, and extreme restlessness. This is an immediate emergency.
• Kidney or liver disease. Can cause chronic or intermittent vomiting, often with other signs like increased thirst, weight loss, or changes in urination. See our guide on dog kidney disease for more information.
• Gastrointestinal parasites. Roundworms, hookworms, and giardia can cause vomiting and diarrhea. Puppies are especially vulnerable. Regular deworming prevents this.
• Bacterial or viral infection. Other than parvo, conditions like distemper and bacterial gastroenteritis can cause significant vomiting. Vaccination prevents many of these.

When Vomiting Is an Emergency: Red Flags

Do not wait to "see if it gets better" if any of the following are present. Call your veterinarian or the nearest emergency clinic immediately.

The Bland Diet Recovery Plan: Step by Step

Once your dog has not vomited for at least 6-12 hours and is keeping water down, you can begin reintroducing food. The goal is to ease the digestive system back to normal gradually — not to rush.

1. Start with a small amount of bland food. Offer one to two tablespoons of boiled chicken and rice for a small dog, or two to three tablespoons for a larger dog. Mix the chicken and rice in roughly equal parts. If your dog vomits after this, stop and call your vet.
2. Feed small meals every 4-6 hours. Do not let your dog eat a large meal at once. Frequent small meals are much easier on an upset stomach.
3. Monitor for 24 hours. If your dog keeps the bland food down for a full day without vomiting, you can gradually increase the portion size. If vomiting returns, stop and contact your vet.
4. Transition back to regular food over 3-5 days. Mix a small amount of regular food into the bland diet, increasing the ratio slowly. For example, start with 25% regular food and 75% bland food for a day, then 50/50, then 75/25, and finally all regular food. Abrupt switches can trigger another episode.
5. Keep your dog hydrated and rested. Avoid vigorous exercise during recovery. Short, gentle walks are fine, but let your dog rest as much as they want.

Preventing Future Vomiting Episodes

Once your dog has recovered, focus on reducing the risk of it happening again. Most mild vomiting episodes are preventable with a few simple changes.

• Secure garbage and food. Use locking trash cans, keep food out of reach, and store pet food in sealed containers. Dietary indiscretion is one of the most common causes of vomiting.
• Use a slow feeder bowl. If your dog eats too fast, a slow feeder bowl reduces the amount of air swallowed and decreases the risk of regurgitation and bloat.
• Transition foods gradually. Always mix old and new food over at least 7 days when switching diets. This gives the gut bacteria time to adjust.
• Keep up with parasite prevention. Regular deworming and flea control prevent many gastrointestinal problems. See our guide on monthly parasite prevention for a schedule.
• Avoid feeding table scraps. Human food is often too fatty or contains toxic ingredients. Stick to dog-specific treats and food.
• Supervise chew time. Bones, rawhide, and small toys can cause obstructions or vomiting. Choose safe chew toys and replace them when they get small. See our guide on safe chew toys for dogs.
• Manage stress. Some dogs vomit from stress or anxiety. If your dog is prone to stress-related stomach upset, our guide on dog anxiety wraps may help.
• Schedule annual wellness exams. Regular vet visits catch underlying conditions before they cause repeated vomiting. For a full checklist, see our guide on dog vaccination schedules and wellness care.
