6 Reasons Why Your Dog Is Throwing up Yellow Bile

Almost anyone with a furry four-legged canine knows the sound of agaggingorvomiting dog. It’s an unfortunate and anxiety-inducing sound, especially when you find a pile of yellow, bubbly, watery, gooey-looking liquid.

Your dog throwing up yellow bile can mean a multitude of things, and some of them can be concerning.

My Dog Is Throwing up Yellow. What’s Happening?

Typically, yellow vomit is commonly bile. Bile is produced in the liver and gallbladder. It breaks down fats and oils in the small intestine while helping your dog’s body absorb nutrients. Bile is very alkaline, so it helps neutralize acidic stomach contents, protecting the sensitive small intestinal lining. But when bile leaks into the stomach, it reacts with stomach acid—and your dog might vomit.

Bile is typically yellow or greenish and usually odorless. It can be full of mucus, bubbly, or foamy. Sometimes it’s seen in one pile or a couple, typically in small amounts, or mixed with water.

Why Dogs Vomit Yellow Bile

While vomiting bile is a common issue pet parents see in their pups, the exact cause can range from minor to more severe. Here are some of the underlying causes of bile vomiting in dogs.

1. Bilious Vomiting Syndrome

Bilious vomiting syndrome (BVS) is sometimes used to describe a condition where dogs vomit bile or froth—but not food—after not eating for a while. For most dogs, this happens early in the morning after not eating overnight.

Dogs with BVS may show obvious signs of nausea, especially first thing in the morning.Nausea in dogsoften manifests as:

• Lip-smacking

• Drooling

• Panting

• Reduced interest in food

For some dogs, it’s thought that the fasting period between dinner and breakfast can result in intestinal fluid flowing backward into their stomach. This can lead to irritation, nausea, and vomiting.

Although BVS is not typically life-threatening, talk to your veterinarian to rule out other causes of vomiting in your pet, as some can be serious. The vet can recommend testing and treatment that’s right for your dog. If standard diagnostics such as a blood panel and physical exam are suggestive of BVS rather than something more serious, your veterinarian may recommend dietary adjustments or medications.

If your dog continues to vomit after changing feedings, consider medical treatment. Antacids and/or medications that increase stomach motility are frequently used. A single evening administration of medicine is usually enough to prevent clinical symptoms.

2. Gastrointestinal Diseases

When a dog is throwing up yellow bile acutely (a sudden onset) or chronically (continuously over time), a multitude of problems could be affecting the digestive system, including:

• Inflammatory diseases of the gut

• Ulcers

• Bacterial or viral infections

• Parasite infestations

• Certain cancers

In each of these cases, the underlying condition needs to be diagnosed and treated by a veterinarian.

Because bile’s acidity can wear down the esophagus, it can lead to ulcerations if left unchecked. Breeds with sensitive stomachs that are predisposed to such problems includeBulldogs, toy breeds,Labrador Retrievers, andPoodles.

3. Pancreatitis

Endocrine disorders such aspancreatitiscan occur after a dog ingests highly fatty or oily foods. But 90% of the time, the inciting cause of pancreatitis in dogs is idiopathic, meaning it cannot be determined.

This condition causes inflammation of the pancreas, and in turn bilious vomiting, along with intense abdominal pain anddiarrhea. Pancreatitis usually occurs three to five days after a dog eats fatty foods, but it can occur as early as 24 hours after.

To help treat pancreatitis, veterinarians will provide care to prevent dehydration and electrolyte imbalances. During this time, treatment often includes withholding food to allow the pancreas to rest.

4. Addison’s Disease

Addison’s diseaseis another endocrine disorder—particularly a disorder of the adrenal glands—that is often characterized by vomiting. With adrenal glands that aren’t producing enough corticosteroids (stress hormones), dogs with Addison’s disease can be critically affected by the tiniest amount of stress.

5. Intestinal Blockages

Regular vomit can become yellow bile after a dog’s stomach has been emptied (though if your dog is vomiting, it’s ideal to address the problem before reaching this point). Along with vomiting bile, an extreme lack of energy and severe abdominal pain mayindicate an intestinal blockage.

This is a medical emergency, and your dog should see a veterinarian right away. Surgery is the most common method for removing the obstruction causing the blockage.

6. Allergies

If your dog eats something they’re allergic to, vomiting may occur and bile may be present. Often, this happens when adog switches their diet. Commonfood allergies in dogsinclude:

• Beef

• Dairy

• Wheat

• Egg

• Chicken

• Corn

• Lamb

• Soy

• Pork

• Rabbit

• Fish

In other cases, a dog may become allergic to something they’ve eaten regularly for years. Most pets develop food allergies between 1–5 years of age.

In this case, astrict 12-week diet trialmay be needed to identify the offending protein. A veterinary nutritionist can also create a diet that removes the allergen without depriving your dog of the vitamins and nutrients needed to function at full strength.
