1. Empty Stomach (Hunger Vomiting)
When a dog’s stomach is empty for too long, it can produce bile, which irritates the stomach lining. This often results in vomiting white or yellowish foam.
What to Do:
- Feed your dog smaller, more frequent meals.
- Avoid letting long hours pass between meals.
2. Gastrointestinal Upset
Eating something they shouldn’t, like grass, garbage, or spoiled food, can upset a dog’s stomach and lead to vomiting foam.
What to Do:
- Monitor your dog to ensure they’re not eating non-food items.
- Offer plain, boiled chicken and rice for a day to settle their stomach.
3. Kennel Cough
This respiratory infection, similar to a cold in humans, can cause dogs to cough up white foam. It’s highly contagious and often spreads in places where dogs gather, like parks or boarding facilities.
What to Do:
- Keep your dog away from other dogs until they recover.
- Consult your vet for medications if the cough persists.
4. Acid Reflux
Acid reflux happens when stomach acids flow back into the esophagus, causing irritation and white foam vomit.
What to Do:
- Feed smaller, frequent meals.
- Avoid feeding right before bedtime to give their stomach time to settle.
5. Bloat (Gastric Dilatation-Volvulus)
Bloat is a serious condition where the stomach twists, trapping gas and fluid inside. One symptom is vomiting white foam, often accompanied by a swollen belly and restlessness.
What to Do:
- Treat this as an emergency and contact your vet immediately.
- Avoid letting your dog eat too quickly by using slow feeder bowls.
6. Pancreatitis
Inflammation of the pancreas can lead to vomiting, including white foam. This condition often occurs after eating fatty foods.
What to Do:
- Avoid feeding high-fat foods like table scraps.
- Consult your vet if vomiting persists, as pancreatitis requires medical care.
7. Parvovirus
Parvovirus is a highly contagious and potentially fatal disease, especially in puppies. Symptoms include vomiting white foam, diarrhea, and lethargy.
What to Do:
- Seek immediate veterinary care.
- Ensure your dog is up to date on vaccinations.
8. Rabies or Other Serious Infections
Although rare, white foam vomiting can indicate rabies or other severe infections. Other signs may include aggression, drooling, or strange behavior.
What to Do:
- Contact your vet immediately if you suspect a serious infection.
When to Worry

While occasional white foam vomiting might not be a cause for concern, certain signs mean it’s time to see a vet. These include:
- Vomiting frequently or repeatedly.
- Signs of pain, such as whining or pacing.
- Blood in vomit or stool.
- Swollen belly or difficulty breathing.
- Lack of appetite or extreme lethargy.
What Your Vet Might Do
If you take your dog to the vet for white foam vomiting, they might:
- Perform a physical exam.
- Ask about recent changes in diet or behavior.
- Conduct diagnostic tests like X-rays or bloodwork.
- Provide treatments such as medications, fluids, or specific diets.
Preventing White Foam Vomiting

Here are some tips to keep your dog’s tummy happy and healthy:
- Feed Regularly: Provide meals at consistent times to avoid an empty stomach.
- Avoid Table Scraps: Stick to dog-friendly foods to prevent gastrointestinal upset.
- Keep Them Hydrated: Ensure your dog always has access to fresh water.
- Supervise Outdoor Activities: Watch for your dog eating grass, garbage, or other non-food items.
- Use Slow Feeder Bowls: These can prevent bloat in dogs that eat too quickly.
Final Thoughts
Seeing your dog vomit white foam can be unsettling, but it’s often not as serious as it looks. Pay attention to their behavior, and if you’re ever unsure, don’t hesitate to reach out to your vet. A little care and quick action can make all the difference in ensuring your furry friend stays happy and healthy. The white foam is typically just a mixture of stomach acid and saliva. The dog may have already thrown up all their stomach contents due to indigestion, eating too fast, or simply eating something that doesn't settle well. After vomiting, a dog should eat a bland diet to help soothe their stomach. Boiled chicken and white rice or plain, canned pumpkin are commonly recommended. Gradually reintroduce their regular food over a few days. Ensure they stay hydrated and avoid feeding large meals. The white foam could mean he has little food left and you're seeing beaten gastric juices and saliva. The mucus lining his stomach is irritated and this is what you are seeing. Don't feed him his normal food yet as his stomach needs to settle down. Maybe offer him some ice chips vs water. Rapid intake of water with overexpansion of the stomach can lead to expulsion of clear, slimy fluid. If vomiting occurs as an isolated episode, veterinary attention is normally not needed. But if the dog has repeated or severe episodes of vomiting, call your vet.
