Is Your Dog Throwing Up Yellow Vomit?

Dogs vomit. Anyone who’s spent a lot of time around canines knows this for a fact. The most common form of vomit is bile or bile reflux. It’s yellow or greenish in color and usually odorless. It can have the consistency of goo, be full of mucus … or be air-filled and foamy. Here’s what it means when you see your dog throwing up yellow …

What Is Bile?

Bile comes from the liver and gallbladder. It breaks down fats and oils in the small intestine … it helps your dog’s body absorb nutrients. Here’s a bit more detail on how that works.

Bile comes from recycled red blood cells that get converted into bilirubin through cellular metabolic processes in the liver. Bilirubin goes through the bile ducts into the gall bladder and breaks down dietary fats for digestion. Bile is very alkaline so it helps neutralize the acidic stomach contents, protecting the sensitive small intestinal lining. The acidic content of the stomach passes through the pyloric valve into the duodenum … then the pyloric sphincter closes. If It doesn’t close, bile leaks into the stomach and reacts with the acid left in the stomach. This is what you see when your dog vomits up yellow vomit.

So let’s talk about what to do if you see your dog vomiting yellow bile or foam.

3 Common Reasons For Yellow Dog Vomit

Here are some of the common reasons for a dog to vomit yellow foam or bile …

Reason 1: Empty Stomach

An empty stomach is the most common reason for a dog throwing up yellow bile.

Lack of food can cause bile to build up and irritate your dog’s stomach lining. So, depending on when your dog normally has his meals … you may see your dog vomiting yellow bile at night or in the early morning.

As dogs age, vomit happens more due to an empty stomach. Fortunately, this condition has an easy fix:

  • Feed smaller meals and …
  • Give your dog a snack at bedtime

These two things will help you avoid a dog throwing up yellow bile in the morning.

While there are common reactive foods like soy, corn, and wheat … any type of food can cause a reaction. Food sensitivities can develop over time and they’re usually a sign of an unhealthy gut.

Your dog’s gut is lined with a mucous membrane that stops pathogens from getting into your dog’s bloodstream. But it can get damaged by things like poor diet, antibiotics, NSAIDs and other drugs, stress, and environmental toxins. Then the spaces in the gut lining expand and allow substances like bacteria, viruses, and undigested food particles into the bloodstream. This is known as leaky gut syndrome and it leads to chronic problems like allergies or food intolerances … as well as more serious long-term problems like arthritis, autoimmune disease, and even cancer.

So, if your dog’s gut is unhealthy, new foods can also be the reason for your dog vomiting yellow. When you introduce a new food, try it first in a separate meal before adding it to your dog’s regular food so it doesn’t cause an irritated stomach (called gastritis).

Sometimes you’ll see your dog eat grass or dirt … and then throw up yellow bile mixed with grass. Dogs do this to help cleanse the digestive system and it’s not usually anything to worry about.

If your dog has severe gastritis … give his digestive system a break by:

  • Fasting for 24 to 48 hours, or …
  • Giving room temperature or slightly warmed bone broth for 24 to 48 hours

Inflammatory vomiting weakens the spleen. So it’s important to avoid serving your dog’s food cold or straight out of the fridge. Leave food on the counter until it’s room temperature.

Reason 2 – Diet Issues

Diet plays a significant role. Abrupt dietary changes or long gaps between meals can trigger bile vomiting. Maintaining a consistent feeding schedule and ensuring a balanced diet can help address this issue.

Reason 3 – Gastrointestinal Issues

Underlying gastrointestinal problems, such as infections or inflammation, can contribute to bile vomiting. Identifying and treating these issues is essential for your dog’s health.

Reason 4 – Bilious Vomiting Syndrome

Bilious Vomiting Syndrome is a condition characterized by recurrent episodes of vomiting bile. Understanding the symptoms and triggers is key to managing this syndrome effectively.

Reason 5 – Eating Grass

Dogs may eat grass, a natural behavior, to induce vomiting and relieve stomach discomfort. However, excessive grass consumption can lead to bile vomiting. Monitoring and controlling this behavior is important.

Reason 6 – Medical Conditions

Various medical conditions, such as pancreatitis or liver disease, may manifest through bile vomiting. Seeking veterinary advice is crucial to diagnose and treat these underlying health issues.

Here are some herbs you can use to help with your dog’s yellow vomit. Read the descriptions and find the one that best fits your dog.

Meadowsweet

Meadowsweet is good for acidity in the stomach, over-reactivity, and pain. It’s well-indicated for dogs who are thin, cool, and lacking vitality.

If using dried meadowsweet, administer it twice daily with food:

  • 150 mg. for particularly small and small dogs

Marshmallow root

Marshmallow root calms the stomach and reduces heat. It coats and soothes the gastrointestinal tract and relieves inflammation.

Use a marshmallow pod or chopped root and steep it in cold water overnight. Both can be taken with food. For capsules, use the following amounts twice daily:

  • 1/2 capsule for small dogs,
  • 1 capsule for medium and large dogs
  • 3 capsules per day for very large dogs (2 capsules in the morning and 1 in the evening).

For an infusion, take 2 tablespoons of marshmallow root in 2 cups of water and leave overnight. Filter and administer these quantities twice a day:

  • 2 spoons for particularly small dogs
  • 3 spoons for small dogs
  • 2 spoons for large-breed dogs

Chamomile

Chamomile helps relieve cramps and inflammation of the digestive tract. It envelops and soothes the mucous membranes and tissues.

  • 1-2 tablespoons for particularly small dogs
  • 3 spoons for small dogs
  • 1-2 tablespoons for large dogs

For inflammation (gastritis) of the digestive tract, I like to use a combination of herbs when I see a dog vomiting yellow. You can mix the infusion of chamomile and lemon balm leaves with marshmallow glycerite.

Preparation: infuse chamomile and lemon balm as described above. Mix 4 ounces of cooled infusion with 20 drops of marshmallow. Use the same dosage regimen as chamomile infusion.

Here’s another yellow vomit mix, prepared by holistic veterinarian Cheryl Swartz. She (she IS the author of “Four Paws-Five Directions”). It is a blend of turmeric root, dandelion root, and chamomile. It refreshes and soothes the stomach and eliminates stagnation in the liver.

Administer these quantities 2-3 times a day.

  • 1/2 dropper for small dogs
  • 1-2 drops for medium-sized dogs

Licorice

Licorice coats the digestive tract and has a refreshing effect. It can be used short term to relieve acute bilious vomiting and heartburn.

Use a licorice glycerin extract. Administer these amounts twice daily on an empty stomach for 1 to 10 days during an active episode of bilious vomiting.

  • 3 drops for very small dogs
  • 5 drops for small dogs

When you shouldn’t treat yellow vomit at home

It is common for a dog to vomit yellow bile. However, if your dog frequently vomits yellow bile or foam and the above solutions do not help, the cause is not simple and you should consult your vet. Here are some examples.

Intestinal blockage

Some dogs eat inedible objects, such as socks or hard toys. These objects can cause a blockage in the digestive tract. If you see your dog vomiting yellow bile when he is also constipated or unable to keep liquids down, take him to the vet immediately.

Bloat or GDV

If your dog repeatedly vomits yellow or white foam or tries to vomit without anything coming out, this could be a sign of bloat (also called GDV – gastric dilatation and gastric volvulus). If your dog’s gums are pale, his stomach is tense, or he is restless and distressed, don’t hesitate to consult your vet. Gastric volvulus is fatal because the stomach can fill with gas and twist so that it closes at both ends.

Don’t stop to think about it. Timing is everything when it comes to bloat.

Giardia

If you see your dog vomiting yellow, Giardia could be a possible cause. This parasite causes other symptoms, including severe diarrhea and possibly lethargy.

If you suspect your dog has giardia, take a fecal sample to the vet for analysis.

Pancreatitis

Inflammation of the pancreas is painful and sometimes serious. Pancreatitis usually occurs because the dog cannot digest fats and oils.

Pancreatitis can be acute or chronic. Symptoms include lethargy, cramps, decreased appetite, diarrhea, and abdominal pain. If you notice these symptoms, it is best to take your dog to the vet for a visit.

Severe gastrointestinal disorders

If your dog regularly vomits yellow vomit, it could be a sign of a serious gastrointestinal problem. This may be cancer, ulcers, or chronic inflammation.

In these cases, the dog may present other symptoms, such as…

  • loss of appetite
  • lethargy
  • dehydration
  • fever
  • weight loss
