Canines are always spitting something up but a dog vomiting yellow bile should be a cause of concern. It can be very difficult to understand what caused it especially since dogs cannot talk. They cannot explain the reason for it and how they are feeling.

If your dog is vomiting, it is important that you know about the bilious vomiting syndrome. Bile is important in food digestion and waste removal functions. Bile is formed in the liver but is stored in the gallbladder until food is taken in.

The gallbladder then releases the bile in small amounts to help in digestion and food emulsification. But when bile abnormally enters the stomach, it can cause irritation and vomiting. This is called the bilious vomiting syndrome. At times when the bile is not vomited, it stays in the stomach and causes gastric reflux.

Predispositions and Symptoms of Dog Vomiting

If your older canine is throwing up, you should pay more attention to the frequency and vomit color. Dogs in their middle age as well as mature canines are prone to this syndrome. Canines that have had duodenitis and gastritis are more prone to dog vomit. This occurs in all breeds, including mongrels, and it affects male and female canines. Common symptoms for a dog throwing up yellow bile are:

Chronic intermittent vomiting with bile of yellow/green tint that occurs in the morning or late at night

  • Lack of appetite
  • Discomfort in the abdomen.
  • Nausea
  • Loss of weight

What are the Reasons for a Dog Vomiting Yellow Bile?

There are various reasons for your dog vomiting mucus of a yellow color. Dog vomiting yellow bile major causes include:

  • An injury
  • Complication from another digestive problem
  • Problems with the stomach being able to handle stomach bile
  • Permanent injury to the stomach lining after a digestive illness causing it to expel the bile
  • Diseases causing gastritis or intestine inflammation and affecting gastrointestinal motility
  • Stomach or intestinal reflux which occurs when the dog’s stomach has remained empty for a period of time

Diagnosis and Treatment for Dog Vomiting Bile

In order to have the proper diagnosis, you will need to consult a veterinarian. As much as possible, you need to give him information about your pet’s health, background history of his symptoms, recent activities or incidents that could have caused the condition, when the symptoms began and the frequency of the vomiting.

The vet can do a thorough examination including a blood profile, chemical profile, blood count and urinalysis. In some cases, a stool examination, biopsy and endoscopy are required. In a biopsy, the pet will have to be placed under anesthesia but with endoscopy, a tiny camera is inserted to examine the stomach. An ultrasound of the abdomen can also be done.

If the dog is behaving normally, save for the vomiting, you don’t need to give him medication. But if the doctor finds something is wrong with your pet, he can recommend drugs that aid in gastric motility and drugs that decrease acid secretion in the stomach.

Understanding why dogs vomit is the first step to treating this condition. Canines respond to treatment differently. Others may require only a short treatment while others need a long course of treatment.

If the dog has chronic bilious vomiting syndrome, it is important to include a dietary change in the treatment method. A dog vomiting yellow bile can indicate a serious condition and should not be overlooked.
