Dog Throwing Up: Causes & What to Do

Common Causes of Dog Vomiting

Dogs frequently vomit due to harmless behaviors like eating grass, garbage, or spoiled food. This is often the body’s way of clearing irritants from the stomach. Overeating, especially in puppies who eat quickly from a shared bowl, can also trigger vomiting. Motion sickness during car rides is another frequent cause, though most dogs outgrow it with time. Stress, phobias (like thunderstorms), and infections—such as parvovirus—can also lead to vomiting. In some cases, vomiting is a sign of serious underlying conditions, including kidney or liver disease, diabetes, pancreatitis, or intestinal blockages from swallowed objects like toys or bones.

When Vomiting Is a Red Flag

While occasional vomiting is normal, certain signs mean a vet visit is urgent. Persistent vomiting—especially if it continues for more than a day—or vomiting that includes blood, coffee-ground material, or bile on an empty stomach may indicate a serious problem. If your dog is weak, lethargic, or shows signs of dehydration, seek immediate veterinary care. Vomiting with diarrhea, or vomiting that returns after trying to reintroduce food or water, also requires professional attention. Puppies, senior dogs, and those with existing health issues are more vulnerable and should be seen by a vet sooner.

Home Care for Mild Vomiting

For healthy adult dogs with one or two episodes of vomiting and no other symptoms, home care may be safe. Start by withholding food and water for at least 12 hours to rest the stomach. After that, offer small amounts of water or ice chips every few hours. If the dog keeps it down, slowly introduce a bland diet—such as boiled rice mixed with lean, fat-free meat (chicken or beef), cottage cheese, or strained baby food. Feed small portions every few hours and gradually increase over two days. Avoid fatty or spicy foods during recovery.

What Not to Do: When to Avoid Home Treatment

Do not attempt home care if your dog is a puppy, senior, or has a chronic illness. Never delay a vet visit if vomiting is severe, bloody, or accompanied by weakness, lethargy, or diarrhea. If vomiting continues despite fasting, or returns when food is reintroduced, seek veterinary help immediately. These signs may indicate a blockage, infection, or organ failure requiring IV fluids, medication, or surgery.

Prevention Tips for Future Episodes

Prevent vomiting by feeding your dog regular, measured meals and avoiding sudden diet changes. Keep garbage, toxic plants, and small objects out of reach. If your dog eats something questionable, monitor closely but don’t panic—many dogs recover quickly. For motion sickness, gradually acclimate your dog to car rides. Regular deworming helps prevent vomiting from roundworms, especially in puppies.
