Have you seen your dog throwing up yellow foam? Yes, it may be a good reason to take it to the vet. But first, there are a few things to consider. Vomiting is quite common to dogs, that’s a fact. The presence of a yellow foam mostly indicated there is bile in the vomit, and you are about to understand what it means.

Within the next paragraphs, you’ll find out what can give your dog vomiting and diarrhea. Also, you won’t have any doubts regarding the meaning of specific colors when your pet throws up. Grab a pen to take notes. Let’s continue with PetscareHQ…………..

When It’s Not a Matter of Concern

After seeing their dog throwing up yellow fluid, some people panic. It’s understandable, but not always necessary.

The yellow foam will sometimes indicate an empty stomach. Their system has to get rid of the bile, which is a fluid produced by the liver if it isn’t used to digest food. If that’s the case, dividing the current meals of a healthy plan may help.

And what if there is something else in the vomit? If it’s grass, you are not alone. Make sure to keep your pet away from it, and you won’t have a problem with your dog tasting what it shouldn’t.

However, anything else or recurrent episodes without any clear explanation become a matter of concern. Your dog throwing up undigested food several times could also lead to malnourishment, which is another reason to see a vet.

Conditions That May Cause Vomiting with Bile

A dog vomiting yellow may have a problem.

Taking to a specialist vet is always the best thing to do when concerned. Several conditions may lead to it. Some aren’t so serious and will suddenly disappear after the cause is extinguished, such as:

  • Side effects of medication;
  • Sudden change in the diet;
  • Stress.

Others, such as parasites and diseases, could lead to the same problem. Those are relevant and can have severe effects on the health of your dog. Following this paragraph, you’ll get to know some of them.

Bilious Vomiting Syndrome

This condition occurs when the bile, which we mentioned earlier, is released into the stomach without any food to digest. It also happens when a dog eats more fat or ingests more water than usual. Also, eating grass may lead to it.

As said earlier, smaller meals throughout the day may help. Vets recommend a diet that is low in fat and high in fiber. You can check the food you give your dog for information on the nutrients.

Gastrointestinal Diseases

Dogs have a small intestine that occupies 25% of the entire gastrointestinal system. That number equals us, people. The difference is that their transit time is usually only 6-8 hours. However, when it comes to diseases in the GI, we are similar.

Dogs suffer from heartburn and a series of other conditions that affect the GI system. There are several cases in which such a problem may appear in your dog:

  • Parasite Infections;
  • Cancer.

It’s important to check with a vet your dog’s general GI health. Now, let’s continue to review the possibilities.


The ingestion of fatty or oily food can lead to pancreatitis in dogs. Pancreatitis is an inflammation that causes your dog vomiting and diarrhea. Under this condition, it’s highly likely to see your dog vomiting yellow.

Intestinal Blockages

While responsible owners avoid giving specific things that may be bad to their dogs, not everyone is aware of the dangers. Toys and even little ones can cause a blockage in their intestine. A dog suffering with it will probably vomit a lot, which will at some point become bilious.

Now, you’ll have your main questions about your dog throwing up yellow foam answered.
