Yellow Dog Vomit: Causes and Symptoms

Many things can affect your dog’s digestive system. So, read this article to find out what yellow dog vomit means and how to treat it.

What is yellow dog vomit?

The yellow substance that your dog vomits is nothing but bile. This secretion that’s produced by the liver, is stored in the gallbladder until it’s released to help digest food. Once the digestive process begins, the bile is released into the small intestine to finish processing food.

Bile is made up of water, lecithin, cholesterol, bicarbonate ions and pigments, and bile salts. When your dog vomits bile, usually it’s due to the bile that enters the stomach from the small intestine. This happens when your dog has eaten too many high-fat foods or too much grass.

If your dog usually throws up yellow vomit, then you should give him foods that are high in fiber and low in fat to help relieve the symptoms.

If a change in diet doesn’t improve the condition, then it may be caused by an underlying disease. Below are some of the most common diseases:

  • Gastrointestinal problems such as ulcers, parasites, or certain types of cancer. The acidity coming from the bile can irritate the esophagus and cause ulcers. This can take place in certain breeds such as bulldogs, retrievers, and small dogs.
  • Pancreatitis. This occurs when the pancreas becomes inflamed. The pancreas is responsible for producing the secretions for the digestive system and hormones such as insulin or glucagon. This disease can also occur after eating foods that are high in fat. It can cause stomach pain, diarrhea, and yellow vomit containing bile.
  • Intestinal obstructions. Some bones, toys, or hairballs can get lodged in your dog’s intestine and cause intestinal obstructions. If you suspect that your dog may be suffering from a blockage, go to the closest 24-hour emergency veterinarian hospital.
  • Allergies. If certain foods are causing yellow dog vomit, most likely your pet may have an allergy. Sometimes, this is due to abruptly changing your dog’s diet. However, this can be corrected by gradually changing his to food. Also, keep in mind that animals can develop allergies to foods they eat on a regular basis.
Allergies can cause yellow dog vomit.

No matter what, if you see yellow dog vomit in your yard or house, you should call your veterinarian to properly diagnose your pet. Try taking your dog to the vet as soon as possible to prevent your pet from becoming weak after passing several hours eating or drinking.
