Seeing your dog spit up foam can be concerning. While it might be as simple as an empty stomach, it may hint at something more serious, like bloat. Understanding why your dog is vomiting foam can make all the difference in getting them back to feeling their best again.
Let’s explore the common causes of foamy vomit, when to contact the vet, and practical tips you can use at home.

What to do if your dog vomits foam
When it’s a one-time event
If your dog vomits foam just once and seems fine afterward, it may be nothing serious. Common causes include eating grass, drinking too much water, or a mild stomach upset.
Here’s what to do:
Hold off on food for a few hours, including treats (but ensure water is available).
Gradually reintroduce regular meals over the next day.
Monitor them for any changes in health.

Contact your veterinarian if your dog:
Vomits repeatedly or can’t keep food or water down.
Appears lethargic, dehydrated, or in pain.
Shows signs of bloat, like a swollen belly or dry heaving (vomiting unsuccessfully).
Has blood in their vomit or stools, has diarrhoea or other unusual symptoms.
Urgent veterinary care is critical for conditions like pancreatitis, bloat, or poisoning.
Common causes of dogs vomiting foam
1. Bloat (Gastric Dilatation-Volvulus (GDV))
Bloat is one of the most serious causes of foam vomiting. This life-threatening condition occurs when the stomach fills with gas and twists, cutting off the blood flow. Early signs include vomiting foam, a swollen belly, and restlessness.
If you suspect bloat, take your dog to the vet immediately. Emergency treatment is critical and potentially lifesaving.
2. Bilious vomiting syndrome (BVS)
Bilious vomiting syndrome usually happens early in the morning or late at night, especially if your dog hasn’t eaten for several hours. The period of fasting allows bile to enter the stomach, irritating the lining and causing vomiting – usually a foamy mix of yellow bile and saliva.
The occasional bout of BVS isn’t typically a cause for concern, but if it’s happening more often, adjusting your dog’s feeding schedule can help. Offering a small snack before bedtime may prevent their stomach from being completely empty overnight. Speak to your vet if you’re concerned.

3. Eating too quickly
It’s great to see a pup with a healthy appetite but when dogs eat too fast, they can swallow air, leading to regurgitation and foamy vomit.
If your dog gulps down their meals, consider using a slow feeding bowl or offering smaller, more frequent portions to slow them down.
4. Indigestion or upset stomach
Dogs sometimes vomit foam when their stomach is upset, usually after eating something unusual, like discarded food scraps or something they shouldn’t have. This type of vomiting typically resolves on its own once the irritant has been regurgitated. However, if vomiting persists, consult your vet.

Less common, but serious causes of vomiting foam
1. Pancreatitis
Pancreatitis, or inflammation of the pancreas, can cause vomiting, often with foam. As the pancreas aids digestion, inflammation can lead to nausea and vomiting.
Symptoms of pancreatitis:
Vomiting (with or without foam)
Abdominal pain
Lethargy
If you suspect pancreatitis, seek veterinary care immediately. Your vet may suggest dietary changes and medication.

2. Ingestion of toxic substances
If your dog ingests something toxic, foam vomiting may be their body’s way of expelling it. Household chemicals, certain plants, spoiled food, or medications can all cause toxic reactions.
Look out for signs of poisoning like:
Vomiting foam or yellow bile
Tremors or seizures
Difficulty breathing
Excessive drooling
If poisoning is suspected, contact your vet or a pet poison control hotline right away.
3. Kennel cough
Kennel cough is a highly contagious respiratory illness that often leads to severe coughing fits, sometimes causing foam vomiting. It’s common when unvaccinated dogs are exposed to infected pups, such as at kennels or dog parks.
Kennel cough is treatable and usually not life-threatening in healthy dogs. If you suspect kennel cough, consult your vet — especially if you know your dog has been exposed.
Tips for preventing foam vomiting
Vomiting isn’t fun for your pup (or for you). Luckily, a few simple steps can help you both avoid the stress and the mess!
Smaller, more frequent meals: dogs prone to vomiting can benefit from smaller meals to avoid an empty stomach.
Slow feeder bowls: if your dog eats too quickly, a slow feeder can help regulate their pace.
Monitor water intake: encourage your dog to drink throughout the day but prevent gulping large amounts at once, especially after exercise.
