Dog Threw Up Yellow Liquid And Died

Here’s a detailed description of yellow vomit in dogs, emphasizing the seriousness of the situation and when to seek veterinary attention. I’ve also included key takeaways for dog owners.

Yellow Vomit in Dogs: When to Worry

Seeing your dog vomit yellow liquid is understandably concerning. While occasional vomiting with bile may not be life-threatening, it can sometimes indicate severe health issues. Understanding potential causes and when to act is crucial for your dog’s well-being.

What Does Yellow Vomit Mean?

Yellow vomit in dogs typically contains bile, a digestive fluid produced by the liver. Bile helps break down fats and is stored in the gallbladder before being released into the small intestine. Here’s what it might indicate:

  • Empty Stomach: The most common reason. If a dog hasn’t eaten in a while, stomach acids can irritate the lining, causing the dog to throw up yellow bile.
  • Dietary Issues: Fatty foods, food changes, or overeating can upset the stomach.
  • Serious Conditions: Yellow vomit can signal underlying health problems, including:
    • Liver disease
    • Pancreatitis
    • Intestinal blockage
    • Kidney failure
    • Parasites
    • Cancer

When to Seek Urgent Veterinary Care

While not always an emergency, yellow vomit demands your attention. Seek immediate veterinary care if you see any of these signs alongside vomiting:

  • Repeated Vomiting: Vomiting multiple times over a short period.
  • Lethargy: Unusual tiredness, weakness, or lack of energy.
  • Loss of Appetite: Refusal to eat for longer than usual.
  • Diarrhea: Loose or watery stools, potentially with blood.
  • Abdominal Pain: Whining, restlessness, or a hunched posture.
  • Other Signs of Illness: Fever, tremors, change in behavior.

What to Do if Your Dog Vomits Yellow

  1. Observe & Monitor: Pay close attention to the frequency of vomiting, the appearance of the vomit, and your dog’s overall behavior.
  2. Fasting: If your dog vomits once or twice and seems otherwise normal, withhold food for 12-24 hours, but provide plenty of water.
  3. Bland Diet: After fasting, gradually reintroduce food with bland, easily digestible options like boiled chicken and rice.
  4. Seek Veterinary Help: Contact your vet for advice anytime you are concerned. If any alarming symptoms are present, take your dog in for an examination immediately.

Diagnosis and Treatment

Your veterinarian will conduct a thorough examination and may recommend tests like:

  • Bloodwork: Evaluates organ function and checks for infections.
  • Urinalysis: Assesses kidney function and hydration.
  • Imaging: X-rays or ultrasound can visualize blockages or abnormalities.

Treatment depends on the underlying cause:

  • Simple Upset Stomach: May resolve on its own or with supportive care and a bland diet.
  • Parasites: Deworming medication.
  • Blockages: May require surgical removal.
  • Severe Conditions: Could include hospitalization, medications, and sometimes surgery.

Prevention is Key

Protect your dog by following these tips:

  • Quality Diet: Offer nutritionally balanced dog food. Avoid table scraps and sudden changes.
  • Portion Control: Manage food intake to prevent overeating.
  • Regular Vet Checkups: Catch problems early.
  • Preventive Care: Vaccinations and anti-parasite treatments.
  • Supervise During Walks: Prevent your dog from scavenging.

Key Takeaways

  • Yellow vomit is often bile and may indicate minor issues or serious problems.
  • Don’t ignore repeated vomiting, lethargy, or other concerning signs.
  • Timely veterinary care is crucial for diagnosing and treating the root cause.
  • Prevention through a healthy lifestyle reduces the risk.

Remember, you know your dog best. Don’t hesitate to trust your instincts and seek professional help if worried. Early intervention can make all the difference in your furry friend’s recovery.

Why My Dog Threw Up Yellow?

Yellow-colored vomit in dogs indicates that it is mainly composed of bile. This bile is a liquid naturally secreted by your dog’s liver. It is stored in the gallbladder and then discharged into the small intestine. It is then evacuated through the stools with other waste. Bile is an essential liquid for the proper digestion of fats and certain toxins present in the dog’s diet.

Causes Why Dog Threw Up Yellow:

Vomiting in dogs is a nonspecific symptom. Dogs vomit for a multitude of reasons, but stomach conditions are surely one of the most common causes of vomiting. See below the causes of dog vomiting bile.

Plant Poisoning:

The ingestion of certain plants or household products that are not very toxic or ingested in small quantities by a dog can cause vomiting of bile. Be careful, however, “it’s the dose that makes the poison”. The effects depend on the type of plant or product ingested and especially on the quantity ingested.

Inflammation of Liver Cells:

A disease of infectious viral etiology or developing due to disturbances in the functioning of other systems. In addition to general malaise, the dog experiences diarrhea, vomiting, and pain in the abdomen. The dog tries to take a forced position, spreading its chest limbs wide apart, thereby reducing the pressure on the affected area. It is necessary to conduct a thorough diagnosis in the clinic, identifying the underlying factor and prescribing treatment.

Chronic Inflammation Of The Stomach Walls:

Gastritis affects the inner lining of the digestive organ. Characteristic signs of gastritis are vomiting of yellow mucus, loss of appetite, exhaustion, and deterioration of the coat.

Ulcerations of the mucous wall of the stomach or intestines, tumor processes in the digestive system. Vomiting is a frequent accompaniment of serious disorders in the gastrointestinal tract.

If your dog vomits yellow foam with mucus, or there are particles of undigested food consumed the day before in the vomit, you should immediately consult a doctor. It is problematic to independently determine the type of pathological process and its location.


Damage to the digestive system by helminths occurs quite often. In the absence of timely antiparasitic treatments, helminths quickly multiply in the body, provoking dangerous conditions, including intoxication and perforation of the intestinal walls.

Roundworms huddled together in balls provoke blockage of the intestinal lumen. Against this background, yellow vomiting often occurs, with foam and mucus. Severe helminthiasis in puppies can be fatal.

Blood Parasitic Infections:

A disease such as piroplasmosis, which occurs in a dog’s body after the bite of an infected ixodid tick, is characterized by a sluggish course. The first signs of the disease in the form of apathy and lethargy appear a few days after the pathogen enters the dog’s body.

With piroplasmosis, against the background of general intoxication of the body, vomiting, apathy, and an increase in the animal’s body temperature are observed. Without timely treatment, the pet is likely to die.


An infectious lesion that provokes the development of infectious jaundice. The disease is characterized by damage to the circulatory system and most of the internal organs of the animal. If the dog vomits yellow liquid, streaks of blood are found in the vomit, and profuse diarrhea is also observed – it is necessary to urgently take the pet to the clinic.

Inflammation of the Gallbladder:

Cholecystitis is a pathological process characterized by inflammation of the bladder and the reflux of bile directly into the stomach. Severe irritation of the stomach walls occurs and a gag reflex occurs. With cholecystitis, the pet suffers from increased formation of gases in the stomach, and eruptions of gastric contents, especially in the morning immediately after eating.

Gastrointestinal Obstruction:

Dogs often vomit yellow foam due to intussusception, gastric volvulus, and swallowing stones, toys, rags, and other objects. Intussusception is a condition in which the intestines curl in on themselves. This happens more often in young animals because their intestinal wall is still thin. Gastric volvulus is a dangerous condition; large dogs are prone to it when they overeat.

If there is an obstruction, the dog vomits food, water, bile, and yellow foam. All this is accompanied by drooling, acute pain, and sometimes bloating.

The pet may try to eat and drink, but everything that it swallows will be vomited after some time. Treatment is almost always surgical; in rare cases, it is possible to remove the foreign object using laxatives and enemas.

Diet Violation:

When eating too fatty foods, smoked foods, excess spices, or when regularly feeding them from the table, vomiting occurs quite often in dogs. Diarrhea also occurs, and if untreated, the dog vomits bile even without food; there may be a refusal to eat, lethargy, and abdominal pain.

If vomiting occurs once, then symptomatic therapy (antiemetics, antispasmodics, diet correction) is sufficient. But if the diet is violated regularly, this leads to serious consequences. The groups of drugs will depend on what kind of disease caused the dog’s diet.


Sometimes tumors affect the gastrointestinal tract or neighboring tissues. In addition to vomiting, weight loss occurs with preserved appetite, diarrhea, and perversion of appetite (licking walls, and eating inedible objects). Treatment is almost always surgical. Radiation or chemotherapy may also be required.

Pancreatic Diseases:

Inflammation of the pancreas (pancreatitis) or its necrosis (death) is accompanied by periodic vomiting, acute abdominal pain, loss of appetite, and possible diarrhea. A common symptom is a strange dog posture, which is called the “praying dog pose.” In the early stages, antiemetics, diet, painkillers, and drip infusions are used to help the pet.

Endocrine Pathologies:

Vomiting can be a secondary symptom of hyperadrenocorticism (adrenal gland disease) and diabetes. In addition to vomiting, thirst, and appetite increase, the pet’s activity level changes, the skin becomes thinner, and skin damage does not heal for a long time. Treatment includes symptomatic and hormonal (replacement) therapy.

Kidney Diseases:

Kidney damage (nephritis, renal failure) is accompanied by general intoxication (azotemia) and often leads to uremic gastritis.

The first symptoms of kidney damage are lethargy, changes in thirst, increased volume of urine, decreased appetite, and weight loss. During treatment, it is important to adjust the level of electrolytes and the pet’s drinking regimen (diet, drips).

Drugs that relieve symptoms affecting renal blood flow and blood pressure, as well as a diet low in phosphorus, are used.


Dogs have always had problems with heat transfer. Unlike humans, they do not sweat. Their fur protects them from the sun and heat; thermoregulation occurs through breathing. At high temperatures, this may not be enough, which can lead to heat stroke.

In addition to vomiting, diarrhea, unsteadiness of gait or even fainting, rapid breathing, and redness of the mucous membranes often occur. Treatment consists of cooling the pet to its normal temperature and replenishing fluid deficiency.

Motion Sickness in Transport:

Pets can also get motion sickness in transport. Prepare for the trip in advance: do not feed your pet 4 hours before travel, make stops every 1-2 hours. What to do if your dog vomits bile on the road? It is enough to give her a break, and before the trip, you should use anti-motion sickness medications.

Taking Certain Medications:

You should not use anti-inflammatory drugs (steroidal and non-steroidal) without a doctor’s prescription; drugs from the human pharmacy, such as paracetamol, diclofenac, ibuprofen, ketorol, and others, are especially dangerous.

In addition to vomiting, they can cause diarrhea, blood in vomit and stool, lethargy, and severe abdominal pain. Sometimes bleeding develops, which will be complicated by signs of blood loss and shock.

Treatment is symptomatic, gastroprotectors, enveloping agents, antiemetics, droppers, and a special diet are prescribed. Acute blood loss may require a transfusion.

What To Do When Your Dog Vomits Yellow?

Have you checked and found no signs justifying a consultation with the veterinarian? Below are some instructions on how to treat a vomiting dog and help him get back on his feet quickly:

  • Give him something to drink and leave water available to prevent him from becoming dehydrated. Alternate with saline solutions, Regidron is suitable. If your pet continues to vomit and diarrhea begins, inject as much saline solution under the skin as possible.
  • Check to see if he is wheezing or breathing with difficulty. If necessary, it could be a deeper obstruction: take your dog to the veterinarian as soon as possible.
  • Don’t give human medicine. In the best case, the dog will vomit the pill; in the worst, the situation will worsen. The network praises the drug Lansoprazole, intended for people suffering from duodenum and stomach ulcers.
  • Put him on a blanket to help him warm up, comfort him, and reassure him.
  • Leave his digestive tract to rest for 12 to 24 hours (maximum).
  • Then reintroduce food by feeding him easily digestible foods.
  • Ideally split meals by spreading them over 3 to 5 times per day during the following days.

How To Diagnose Why a Dog is Yellow Vomiting?

When a dog develops yellow vomiting, the veterinarian carries out diagnostic measures, which begin with a general clinical examination and anamnesis based on questioning the animal owner. Then a set of studies is prescribed, including:

  • Blood test – general clinical and biochemical;
  • Urine and stool analysis;
  • Radiography;
  • Ultrasound;
  • Gastroscopic examination.

If the results of these studies are not enough, laparoscopic surgery may be prescribed, allowing minimally invasive surgical access to the abdominal organs. The implementation of such surgical manipulations ensures not only diagnosis but also treatment at the same time.

Treatment Of Dog Threw Up Yellow:

Since vomiting is not an independent pathology, but a symptom of an underlying disease, the therapeutic strategy is aimed at eliminating the cause in the following areas:


Diagnosis begins with a history and laboratory tests. If the veterinarian considers it necessary, an instrumental examination is performed – x-rays or ultrasound. If the intestines are blocked by an inedible object or balls of worms, a loop is squeezed, or intussusception has developed. Surgery is the only way to treat such diseases.

Drug Therapy:

Drug therapy involves the destruction of contagion, symptomatic and supportive therapy. For viral diseases of puppies, ready-made polyvalent globulins and serums are used, since the symptoms of different ailments are similar.

Wormism is eliminated with anthelmintics together with detoxicants. In most cases, antibiotics cannot be avoided, since contagions make the mucous membranes of the digestive tract defenseless against the constant intestinal microflora.

Symptomatic Therapy:

The veterinarian monitors the pet’s condition and, as needed, prescribes medications that support the functioning of the heart, liver, kidneys, and alimentary tract, preventing dehydration.

Rehabilitation  Treatment:

After recovery, the dog’s body resembles a desert. All vitamin reserves have been used up. The beneficial intestinal microflora died in a battle with putrefactive bacteria and was also destroyed by antibiotics.

Therefore, the doctor prescribes vitamin preparations, probiotics – live cultures of lactic acid bacteria, and prebiotics – nutritional components available for absorption only by beneficial microbes of the alimentary tract.

Diet Therapy:

In all cases, when vomiting, therapeutic fasting is prescribed, often forced. The body’s enzyme systems become unaccustomed to the usual food, so the pet has to be taught to feed again.

How To Prevent Dogs To Vomit Yellow?

The cause of most pathologies of the digestive system is irregularities in the diet and improper care of the dog. In order to prevent diseases, it is necessary to follow a number of rules:

  • Do not feed the dog food from your table;
  • Prohibit picking up various objects and food on the street;
  • Carry out regular antiparasitic treatments;
  • Do not forget to take immunizing vaccines;
  • Monitor the quantity and quality of food.
  • Proper care and an attentive attitude towards your pet is the key to its health and longevity.


Vomiting is a common symptom in dogs. If your dog vomits bile, refuses to eat, and does not even eat his favorite treats, you should immediately consult a doctor. The yellow color of vomit is given by bile, gastric juice, or the remains of undigested food.
