Vomiting is a common problem in dogs and can have many causes. Sometimes, your dog vomiting yellow foam, which can indicate an empty stomach, a foreign object, or a more serious condition. In this article, I will explain why your dog may be vomiting yellow foam, and what you can do to help.
What Is Yellow Foam?
Yellow foam is a mixture of stomach acid and bile that is produced in the liver and stored in the gallbladder. Bile helps with the digestion and absorption of fats in the small intestine. When your dog vomits yellow foam, it means that there is no food in the stomach to buffer the acid and bile, and they irritate the stomach lining.
What Causes Yellow Foam Vomiting?
There are many possible reasons why your dog may vomit yellow foam, such as:
If your dog has not eaten for a long time or has skipped a meal, the stomach may become empty and produce more acid and bile. This can cause nausea and vomiting of yellow foam, especially before breakfast or several hours after dinner. This is more common in dogs that are fed once or twice a day, rather than small frequent meals.
Dogs are curious animals and may eat things that are not good for them, such as spoiled food, grass, trash, or foreign objects. These can upset the stomach and cause vomiting of yellow foam, along with other symptoms such as diarrhea, loss of appetite, or abdominal pain. Some foreign objects may also get stuck in the stomach or intestines and cause an obstruction, which is a medical emergency.
Bilious vomiting syndrome
This is a condition where dogs vomit yellow foam regularly, usually in the morning or after a long period of fasting. The exact cause is unknown, but it may be related to abnormal motility of the stomach or duodenum, or increased sensitivity to bile. Dogs with this condition may benefit from more frequent feeding, dietary changes, or medications to reduce acid production or improve motility.
This is an inflammation of the pancreas, an organ that produces digestive enzymes and hormones. Pancreatitis can be caused by various factors, such as a high-fat diet, trauma, infection, or certain medications. It can cause severe abdominal pain, vomiting of yellow foam or blood, diarrhea, fever, dehydration, or shock. Pancreatitis is a serious condition that requires immediate veterinary attention.
The liver is responsible for producing bile and detoxifying various substances in the body. Liver disease can impair these functions and cause various symptoms, such as vomiting of yellow foam or blood, jaundice (yellowing of the skin and eyes), weight loss, loss of appetite, increased thirst and urination, or ascites (fluid accumulation in the abdomen). Liver disease can be caused by infections, toxins, tumors, or genetic disorders.
Other gastrointestinal conditions
Many other conditions can affect the stomach or intestines and cause vomiting of yellow foam, such as gastritis (inflammation of the stomach), inflammatory bowel disease (IBD), ulcers (sores in the stomach or duodenum), parasites (worms), infections (bacterial or viral), tumors (benign or malignant), or food allergies (hypersensitivity to certain ingredients).
What Should I Do If My Dog Vomiting Yellow Foam?
The treatment for yellow foam vomiting depends on the cause and severity of the condition. In some cases, your dog may only need some home remedies and supportive care, such as:
If your dog vomits once or twice and otherwise seems fine, you can try to withhold food for 12 to 24 hours to let the stomach rest and recover. However, do not withhold water, as your dog may become dehydrated. You can also offer small amounts of ice cubes or low-sodium chicken broth to keep your dog hydrated.
Feeding a bland diet
After the fasting period, you can gradually reintroduce food to your dog by feeding a bland diet of boiled chicken and rice or boiled hamburger and rice. Feed small portions several times a day for a few days, then slowly transition back to your dog’s normal diet.
Giving ginger or chamomile
These natural remedies can help soothe the stomach and reduce nausea and vomiting. You can give your dog ginger or ginger tea, chamomile or chamomile tea, or a ginger tincture in water. However, do not give these to your dog if they have diabetes, bleeding disorders, or are pregnant or nursing.
If you know what causes your dog to vomit yellow foam, such as eating too fast, eating garbage, or having food allergies, you can try to avoid these triggers by changing your dog’s feeding habits, keeping them away from trash or other harmful substances, or switching to a hypoallergenic diet.
In other cases, your dog may need medical attention and treatment, such as:
If your dog is dehydrated from vomiting, they may need intravenous fluids to restore their electrolyte balance and hydration status. Your veterinarian may also give anti-nausea medications or antibiotics through the IV line.
If your dog has a foreign object or an obstruction in their stomach or intestines, they may need surgery to remove it and repair any damage. This is a life-threatening situation that requires immediate intervention.
Depending on the cause of your dog’s vomiting, your veterinarian may prescribe medications to treat the underlying condition, such as anti-inflammatories for pancreatitis, steroids for IBD, antacids for gastritis, or anti-parasitic for worms.
Some dogs may need a special diet to manage their vomitings, such as low-fat food for pancreatitis, high-fiber food for constipation, or prescription food for liver disease. Your veterinarian will advise you on the best diet for your dog’s condition.

Some cases of yellow foam vomiting may be prevented by following these tips:

- Avoid giving your dog fatty, spicy, or human foods that may upset the stomach.
