Common reasons dogs vomit

Dietary indiscretion: Eating rubbish, grass, table scraps, or sudden diet changes.
Gastroenteritis: Inflammation of the stomach/intestines, often with diarrhoea.
Food intolerances or allergies.
Parasites: Worms and protozoa (more likely in puppies or dogs without regular deworming).
Foreign bodies: Bones, toys, socks—anything that can obstruct.
Toxins: Chocolate, grapes/raisins, xylitol, onions/garlic, certain plants, human meds.
Motion sickness or anxiety.
Pancreatitis: Often after fatty foods; can be severe.
Ulcers, gastritis, or inflammatory bowel disease.
Systemic diseases: Kidney or liver disease, Addison’s disease, diabetes complications.
Medications: NSAIDs, certain antibiotics, supplements.

What to do when a dog vomit

1. Stay calm and observe

Note the frequency, colour, and contents (food, grass, foam, bile, blood).
Watch for additional signs: lethargy, diarrhoea, pain, bloating, drooling, pale gums, collapse.

2. Remove food for a short period

Adult dogs: Withhold food for 6–8 hours after the last vomit if your dog is bright and alert (not for puppies/toy breeds who risk low blood sugar).
Water: Offer small, frequent sips every 30–60 minutes. If your dog can’t keep water down, seek vet help.

3. Reintroduce a bland diet slowly

If vomiting stops for 6–8 hours, try small portions of a bland diet:
- Boiled chicken or white fish (no skin, bones, or seasoning) with plain white rice.
- Commercial veterinary gastrointestinal diet is ideal if available.
Feed 3–4 small meals for 24–48 hours, then gradually mix back regular food over 3–5 days.

4. Support hydration

Offer fresh water; ice chips can help if your dog is queasy.
Consider an oral rehydration solution formulated for pets (avoid sugary sports drinks).

5. Rest and monitoring

Keep your dog calm, avoid heavy exercise, and continue to observe stool, energy, appetite, and vomiting.

When vomiting is an emergency Seek urgent veterinary care immediately if you notice:

Repeated vomiting (more than 2–3 times in 24 hours) or vomiting that won’t stop.
Vomit with blood or “coffee-ground” material.
A swollen, tight, or painful belly; dry heaving with no vomit (possible bloat/GDV).
Severe lethargy, collapse, pale/white gums, or difficulty breathing.
Inability to keep water down.
Known toxin exposure (chocolate, grapes/raisins, xylitol, human meds, rodenticide).
Foreign body risk (chewed toy pieces, bones, clothing).
Puppies, toy breeds, seniors, pregnant/nursing dogs, or dogs with diabetes, kidney, or liver disease.
Vomiting with black/tarry stools, high fever, or severe pain.

What not to do

Don’t give human medicines (ibuprofen, paracetamol/acetaminophen, aspirin, bismuth subsalicylate) unless a vet directs you—many are toxic to dogs.
Don’t force food or large volumes of water.
Don’t give milk, fatty foods, or treats “to settle the stomach.”
Don’t wait if your dog is very unwell—early treatment saves lives.
