My Dog Is Throwing Up Yellow Bile: Causes, Treatment & Prevention

Nothing is worse than seeing your dog throw up and not eating or drinking. There are different possible reasons for the dogs throw up, especially if they eat scraps from the trash or odd items they find on the ground. Unsurprisingly, this can cause stomach upset, usually relieved by throwing up the offending item.

Bile – what is it?

In dogs, yellow throw up usually indicates the presence of bile. Bile is a digestive juice produced by the liver and stored in the gallbladder until required. To help break down food, bile is released into the small intestine when a dog eats.

Dogs Throw up with Bile Symptoms

A variety of factors can cause a dog’s vomiting. The following are symptoms your pet may exhibit before and after throw up :

  • Heaving stomach
  • A drooling sensation
  • Swallowing excessively
  • Vomiting
  • A retching sensation
  • The depression
  • Appetite deficit
  • Having a cough

Causes of Throw up in Dogs

It is important to rule out the following causes of vomiting with bile in dogs:

Pancreas Inflammation

The pancreas disrupts digestion enzymes and can often result in bile vomiting. Eating extremely fatty or oily food can also trigger a dog’s pancreatitis. When the pancreas becomes inflamed, bilious vomiting occurs, accompanied by severe stomach pain and diarrhea.

Acute Gastritis

Due to the lack of food in the stomach, acute gastritis can cause vomiting of bile. Several potentially dangerous gastrointestinal conditions can cause a dog to vomit bile, such as parasitic infections, ulcers, and certain types of cancer.

Intestinal Blockage

The foreign body lodged in the intestinal tract may cause vomiting with bile because it prevents food from being processed into waste, causing vomiting. Toys, bones, cloth, and even hairballs can cause intestinal blockages.

Parasitic Illnesses

Roundworms are the most common intestinal parasite in dogs. Almost all dogs will have an infestation of roundworms at some point in their lifetime. Your dog may throw up yellow bile if it has a heavy worm burden in its digestive tract. Symptoms of parasitic illnesses such as Giardia include acute vomiting and bile production.

Bilious Vomiting Syndrome

A bilious vomiting syndrome is characterized by intermittent vomiting of bile, normally on an empty stomach. Your dog may throw up if its small intestine leaks bile into the stomach, especially if it hasn’t eaten in a while or overeaten.

Systemic Illness

Dogs can vomit bile due to systemic illness. Symptoms of a systemic illness, such as kidney disease, Addison’s disease, or another chronic condition, can cause a dog to vomit bile, including digestive disturbances, diarrhea, constipation, abdominal pain, and jaundice.

Food Allergies

If your dog eats something that causes an allergic reaction, it might vomit (with or without bile). An allergic reaction may also cause your dog to vomit (with or without bile). Many commercial dog foods contain beef, dairy, corn, soy, and other food products that can trigger an allergic reaction in some dogs.

Ingestion of Fatty Food

High-fat diets are more likely to cause problems than low-fat diets. Overfeeding your dog with rich or fatty foods can cause pancreatitis (inflammatory disease of the pancreas). Throw up, abdominal pain, diarrhea, and loss of appetite can result.

Dog Throw-up Treatment

Your dog’s vomiting will be treated based on its underlying cause. It will be easier for your veterinarian to formulate a treatment plan for your dog if you provide them with as much information as possible about your dog’s illness.

If your dog only throws up a few times, watch them. They may also have diarrhea, depending on the cause of the vomiting. Keep them hydrated by providing clean drinking water, and monitor them over the next few hours.

If the dog continues to vomit over a few hours with other symptoms like diarrhea, shaking, and lethargy, go to an emergency vet clinic immediately. For peace of mind, it’s always a good idea to consult an expert if you’re unsure what caused your dog’s illness.

The Best Way to Prevent Dog Throw up

  • Keeping your dog away from items he shouldn’t eat, lick, or chew is the best way to prevent vomiting. Sometimes, vomiting cannot be prevented in dogs since many illnesses have no known cause.
  • Keep treats to a minimum and feed a proper diet.
  • Ensure plants, chemicals, human food, and other toxins are kept away from children.
  • It is important to watch your dog while playing with chew toys, especially if he tends to destroy them.
  • It is important to contact your veterinarian as soon as you notice any signs of illness; delaying will only make things worse. In case of doubt, visit your nearest veterinarian.

Why is my dog’s throw up yellow?

Usually, yellow throw up indicates the presence of bile, which is a digestive juice produced by the liver. It can either appear foamy or thick and sticky.

Can I treat my dog’s bilious vomiting syndrome (BVS) at home?

Try splitting your dog’s daily food allowance into several smaller meals throughout the day if he is otherwise healthy. It would help if you also fed him a light meal before bed. A vet visit is a good idea for your dog if this doesn’t solve the problem.

Is it safe to feed my dog after he throw up bile?

For 12 to 24 hours, you should not feed your dog. After your dog has not vomited for at least six hours, you can offer the dog a small meal. Mix cooked white rice with boiled white meat chicken (no bones or skin), but you can also use a small portion of your dog’s regular food.

Is it safe for my dog to drink water after throw up bile?

Suppose your dog is throw up bile once or twice, which is very isolated. In that case, you can give your dog more water or feed it bland, easily digestible food to replenish its lost fluids while observing its behavior and looking for other signs of discomfort.
