Dog Vomiting Yellow | Treat your Pet’s Throwing Up Yellow Issue

As a pet owner, failing signs of health from your dog can be a major cause for concern. Vomiting in dogs can be a fairly common phenomenon. However, the frequency and nature of occurrence need to be considered for further diagnosis. You are rightly worried if you have witnessed your dog throwing up copious amounts of a yellow substance. This yellowish liquid is bile and can indicate various problems. We look at the reasons behind this and provide a list of symptoms and treatment options. 

Why is My Dog Throwing Up Yellow?

Are you worried about why is my dog vomiting yellow? There are several reasons dogs throw up. Below are some of the most common causes of dog puking bile.

Presence of Bilious Vomiting Syndrome

Bile is produced by a dog’s liver to aid digestion. However, this bile may leak into the stomach. This is generally observed in dogs who haven’t consumed any solid food in a long while or drank abnormally large amounts of water. Dogs can also sometimes chew on things like leaves and grass. The body cannot digest excess bile, which is generally removed by throwing up.

Presence of Gastrointestinal Disease

Your dog vomiting bile may also indicate a preexisting gut issue in it. It can point toward a number of issues affecting the digestive system, such as the presence of parasite infections and inflammation. Ulcers which are fairly common in dogs, can also be a reason. Sometimes, if a dog keeps throwing up bile, it can indicate a much more serious issue, such as stomach cancer. If left unchecked, this acidic bile accumulates in your dog’s body. This, in turn, leads to other issues like wearing down the esophagus. Some species of dogs are highly susceptible to this, such as terriers and bulldogs.

Signs of Pancreatitis in your Dog

If your dog ingests fatty or calorie-rich foods, there is a high possibility of endocrine disorders. One of these could be pancreatitis which occurs when the pancreas gets swollen. This generally occurs a couple of days after your dog has consumed the food and seeks relief by throwing up. The vomit, in this case, has been found to contain large amounts of bile. This is sometimes followed by intense abdominal pain and diarrhea. In the case of severe cases, the symptoms may start showing much earlier. 

Indication of Intestinal Blockages

Given dogs’ propensity to chew and bite on things, they often swallow some of them. These get stuck in the gut and can often create blockages. These are generally quite serious, and the first signs of trouble looming are through your dog throwing up yellow foam. Even if the stomach has been emptied and continues to throw up yellow bile, it may have ingested some foreign object.

Caused Due to Allergies

Sometimes dogs may react to changes in their diets or other factors by vomiting bile. They can be caused due to any number of factors. Either they are not used to the new brand of dog food, or the floor cleaner used to mop their surroundings has triggered an allergic reaction. So such allergies could become the causes of dog vomiting.

What to Do If your Dog Throwing Up Bile?

  • Schedule your dog for an appointment with the vet immediately if your dog throws up yellow. Afterward, please keep your pet under an observation period where you note the number of times they have thrown up and the frequency. Noticing whether the vomit contains partially or undigested food is also a useful record
  • The next step would be to get your dog physically examined by the vet. A series of tests, such as blood count, blood and chemical profile, etc., would follow this. A urinalysis can follow this to understand the cause of the problem.
  • In case of the issue persists, further analysis can be done in the form of an ultrasound to look at the abdomen. Sometimes a biopsy might also be carried out if the vet suspects a larger issue with the liver. 
  • Ensure that the surroundings are optimal to prevent future occurrences. Ensure you keep away houseplants and flowers from their chewing range. Also, ensure that there are no toxic materials nearby that they might be tempted to lick or chew. Ensure proper hygiene when it comes to dog toys by cleaning them regularly.
