why your dog throwing up sometimes a yellowish bilious liquid? This behavior often worries owners, however, rest assured. If this vomiting is frequent in dogs, it is most often not serious. However, this problem can sometimes alert to the presence of an underlying disease.

Discover the signs that should encourage you to consult your veterinarian and the reflexes to adopt to reduce your dog’s bilious vomiting!

Why is my dog ‘s throw up yellow?

throwing up that is yellow in color in dogs indicates that it is mostly made up of bile. This bile is a liquid naturally secreted by your dog’s liver. It is stored in the gallbladder, then it is discharged into the small intestine. It is then evacuated by the stool with the other waste.

Bile is an essential liquid for the proper digestion of fats and certain toxins present in the dog’s diet.

Why is my dog throw up bile?

Benign causes
Most of the time, the causes of bile reflux in dogs are not serious. Bilious vomiting can be linked to:

  • Food. A food not adapted to the needs of your dog can cause digestive disorders. In addition, poor quality food can also be responsible for stomach irritation. Industrial food may, for example, contain poorly digestible or allergenic ingredients.
  • Ingestion of medication. Some medications can have side effects on your pet. Often made up of chemical molecules, they can irritate the mucous membranes of the dog’s stomach.
    More serious causes
    More rarely, throw up bile can be linked to the presence of more serious underlying conditions such as:

  • Inflammation of the stomach such as gastritis,
  • Inflammation of the intestine,
  • An intestinal obstruction which may be linked to the presence of a foreign body or the ingestion of a toxic food,
  • A liver disorder (affecting the liver) such as hepatitis or a liver tumour,
  • A stomach ulcer.
  • Controversial causes
  • Other, more controversial causes may also explain your dog’s yellow vomit. This is for example the case of bilious vomiting syndrome. It is an inflammation of the stomach (gastritis) caused by the animal’s bile when its stomach remains empty for too long.

In this case, vomiting of bile is observed only several hours after eating (when the dog’s stomach is empty). This explanation is debated because the dog’s digestive system is normally adapted to ingesting a meal only once a day.

What can I do to limit my dog’s vomiting of bile?


Improve his diet
Does your dog’s diet meet his needs? A meal made up of too many vegetables or fruits can be responsible for your dog’s bilious vomiting. Indeed, his carnivorous digestive system is not adapted to digest too many vegetables.

To limit the appearance of bilious vomiting, have several reflexes to choose a good diet for your dog:

  • A diet whose composition of vegetables and fruits is not too important.
  • A food rich in good quality animal protein.
  • Some specialists also recommend multiplying the meals given to the dog during the day. This would avoid periods during which the stomach remains empty for too long.

Consult your veterinarian


Three situations should lead you to consult your veterinarian if your dog vomits yellow and you do not know the cause:

  • Other symptoms accompany his bilious vomiting (dejection, fever, constipation, lack of appetite, for example).
  • Your dog vomits yellow regularly (every day for example).
  • Bilious vomiting intensifies over time.
  • You must then quickly consult your veterinarian who will carry out a clinical examination. The causes of vomiting bile in your dog can be mild or more serious. Your veterinarian checks that no underlying disease is present to treat a possible pathology with an appropriate treatment.
