It’s a fact of life that your dog is going to vomit at some point. It is often just the regurgitation of their food because they ate it too quickly, but sometimes, it might be true vomiting, and may indicate that something is wrong.
If your dog throws up bile over one episode of vomiting, and seems otherwise fine, you should be fine to monitor them for a few hours to make sure all is well. However, if they are showing other signs of illness or if it continues to happen, get in touch with your vet.
In the meantime, read on as we discuss the reasons that a dog may throw up bile and what you can expect regarding treatment.
Why Is My Dog Throwing Up Yellow Bile?
If your dog is throwing up yellow liquid, it’s probably bile. The liver produces bile, which is stored in the gallbladder, and released into the small intestine when a dog eats. Bile helps to break down oils and fats in the small intestine into smaller particles that can be absorbed more easily. It also helps neutralize stomach acid which is passed from the stomach to the small intestine along with the stomach contents. This protects the intestinal tract lining. Bile should be prevented from leaking into the stomach by the pylorus, a muscular valve of the stomach. However, when dogs vomit excessively or on an empty stomach, bile can be produced.
If bile is contained in the vomit, it may be yellow or greenish, lack any odor, and may be foamy, bubbly, or mucousy. Your dog may vomit this substance more than once.
What Causes Dogs to Vomit Bile?
What Causes Dogs to Vomit Bile?Several conditions can cause dogs to vomit bile, ranging from minor to severe.
1. Bilious Vomiting Syndrome
Bilious vomiting syndrome is a condition that entails dogs throwing up bile when they haven’t eaten for a while, and it typically occurs in the morning.
- Panting
- Drooling
- Restlessness
- Trembling
- Repeatedly swallowing
- Lip licking
- Retching
It’s thought that for some dogs, waiting too long before eating (which is why this can happen most often in the morning) can result in bile flowing into the stomach. This condition is not considered serious, but if it continues to occur, you should speak to your vet.
You might also want to feed your dog a small meal before bed so they don’t need to wait as long for breakfast. This can help some dogs, but consult with your vet first, as they might need to run tests or offer medication for your dog.
2. Allergies
Food allergies can cause your dog to vomit. Allergies to particular foods (typically certain proteins) typically start to occur when a dog has eaten the food without incident for years.
- Beef
- Dairy
- Chicken
- Wheat
- Excessive scratching
- Paws smelling like corn chips
- Excessive licking of paws
- Chronic ear infections
- Recurring hot spots
- Chronic diarrhea
- Red eyes
- Coughing
If you suspect that your dog might have food allergies, your veterinarian can help you set up an elimination diet to identify the allergen.
3. Gastrointestinal Disorders
Several gastrointestinal diseases can lead to a dog throwing up acutely (suddenly vomiting) or chronically (continuing to vomit over time).
- Switching to a new diet abruptly
- Bacterial or viral infections
- Parasites
- Ulcers
- Certain cancers
- Inflammatory diseases of the stomach
Since many of these conditions require proper diagnosis and treatment, it’s essential to seek advice from a veterinarian, who will determine the underlying condition.
If you have recently switched your dog’s diet without a transition period and your dog has had acute vomiting and diarrhea, it is reasonable to feed your dog a bland diet for a few days to help them settle. If your dog is otherwise unwell, e.g. showing signs of lethargy or a poor appetite, seek veterinary advice.

4. Pancreatitis
Pancreatitis is a medical condition that is most often idiopathic (has no known cause). However, some breeds are predisposed to pancreatitis and it can result from dogs consuming high-fat foods. The condition can be either acute or chronic.
- Persistent vomiting
- Stomach pain
- Lack of appetite
- Lethargy
- Severe dehydration
- Shock and collapse in severe cases
- Loss of appetite
- Lethargy
- Stomach pain and/or vomiting
- Diarrhea
Treatment for pancreatitis varies depending on the severity of the disease. Many dogs will need hospitalisation, fluid therapy, pain relief and anti-sickness medications to help them through a bout of pancreatitis. The current advice is to try to get the dog to eat as soon as possible to give them the best chance of survival. Dogs that have suffered with pancreatitis should be fed ultra-low-fat food for the rest of their lives.
5. Systemic Illnesses
Systemic illnesses are a group of medical conditions that affect many systems or organs in the body. These include Addison’s disease, kidney disease, liver disease, and other chronic conditions.
Digestive upset is a common sign of many systemic conditions, but they usually have more signs than just vomiting. For example, a dog with kidney disease is likely to be drinking excessively, losing weight and may have a reduced appetite.
If your dog is diagnosed with a systemic illness, your vet will provide treatment options and guide you on how to take care of your pet at home.
6. Intestinal Blockage
An intestinal blockage is an emergency situation and requires urgent surgical attention!
- Extreme lethargy
- Severe abdominal pain
- Loss of appetite
- Diarrhea or difficulty pooping
The most common indication of an obstruction is a dog vomiting but not pooping. Surgery is usually necessary.
Should You Go to the Vet If Your Dog Is Vomiting Bile?
If your dog throws up bile only once and seems okay otherwise—eating, exercising, and generally acting normally—it’s likely they are fine.
However, if your dog throws up more than once within 24 hours, it’s best to take them to your vet to ensure that they are okay. You should also speak to your vet if your dog seems to throw up bile chronically, such as every few days or weekly.
What’s the Best Way to Settle Your Dog’s Stomach?
After your dog vomits, you have a few options for your next steps. However, you should ask your vet for their input because treatment options vary hugely depending on the cause of the vomiting. If your dog has vomited multiple times, take them to your veterinarian for assessment.
- Small amounts of boiled chicken and rice, or canned pumpkin
- Plenty of water
Before feeding anything to your dog if they’ve been throwing up, run these options by your vet.
- Chicken and rice
- Shredded chicken
- Bone broth
- Baby food (as long as it doesn’t contain any toxic ingredients, including onions, shallots, garlic, grapes or raisins).
