Understanding dog throwing up white foam: Common Causes Explained

January 9, 2025

A dog’s vomit could be transparent, yellowish, brownish, or white with foam. Several conditions, including indigestion, pancreatitis, viral diseases, foreign bodies ingested, and others, might cause your dog throwing up white foam. If your dog throws up frequently, you should avoid certain foods or objects or take them to the doctor for a thorough examination to rule out major health problems.

Seeing your dog throw up is never fun, but thankfully, it’s usually just a one-time incident. But if your dog throws up, you should watch out for additional signs. Instead of hoping for a miracle cure, immediately take your sick dog to the vet. When a dog vomits white foam, here’s what you should know.

Dogs Throwing Up White Foam—What Is It?

If a dog is throwing up, it’s important to distinguish between actual vomiting and coughing or a mix of the two. Puke can have a variety of textures, including chunky, grainy, semi-liquid, or watery. Similarly, vomit can range in color from brown to yellow to transparent.

A common symptom of an upset stomach is the production of foamy, white vomit due to the combination of saliva, stomach acids in an empty stomach, and excess gas. Forcefully expelling contents from the stomach or upper intestines is known as vomiting. The usual components of vomit include bile, partially digested food, or both.

When your dog starts to gag, he can cough up white foam. This is a common symptom of kennel cough. White foaming mucus can be vomited when coughing if saliva or excess fluid in the lungs combines with the air. When a dog coughs up white foam, it’s not common for its abdomen to constrict, unlike when it vomits. The age group affected, and the nature of the underlying illness determine the specific conditions that can produce white foam vomiting.

Dog throwing up white foam: Why?

White foam in your dog’s vomit could be due to a few different things. Most of the time, a gastrointestinal problem in your dog results from anything he or she tried. Your canine may have been gnawing on something unpleasant, licking something that tasted nasty, or nibbling on grass. But regular vomiting, or any kind, can be a sign of a more serious sickness. Several things can cause white, frothy vomit in dogs, the most prevalent of which are:

Indigestion

For dogs, this is a common sign that they ate something that didn’t agree with them, such as grass or anything from the garbage. Consuming food too rapidly or immediately following strenuous physical activity is another potential cause of indigestion.

Reflux from acid Treatment

The condition when a dog vomits white foam due to an upset stomach caused by an excess of bile or stomach acids is called bilious vomiting syndrome. This is particularly probable if your canine has a history of morning foam vomiting just before breakfast. Reduce the size and frequency of your dog’s meals and give it a snack before bed and first thing in the morning to help alleviate this issue. Antacid medicine is also necessary for some.

Pancreatitis disease

Vomiting is a common symptom of pancreatic inflammation in dogs, and if the dog’s stomach is empty, the vomit may be white and foamy. Pain, loss of appetite, and diarrhea are common symptoms that often accompany pancreatitis. Immediately consult a veterinarian if your canine exhibits any of these signs.

Additional Illnesses of the Digestive System

Inflammation of the stomach caused by germs or viruses might cause your dog to vomit white foam or other colors.

Blockage in the digestive tract

Obstructions in the intestines can occasionally form in dogs that swallow foreign objects, such as chunks of bone or toys. Surgery may be necessary for this potentially life-threatening condition. Please contact your veterinarian immediately if your dog exhibits any more symptoms of discomfort or pain when vomiting.

Exposure to Toxins

A dog may vomit white foam out if it ingests anything poisonous, such as certain meals, medicines, cleaning products, or toxic plants. On the other hand, other symptoms, including weakness, trembling, or repeated vomiting episodes, are more frequent. Again, you need to contact your vet right away for this one.

Rabies

Although rabies is quite uncommon in the US due to extensive immunization programs, your dog can still vomit white foam if it gets the disease.

Bloat

This uncomfortable ailment can build up gas, fluid, or food in a dog’s belly. White foamy vomiting is a possible early sign. Immediate medical attention is required in the event of bloat. You should contact your vet immediately if your dog has an enlarged tummy, seems uncomfortable, and cannot defecate. If this occurs outside of regular business hours, get to the closest open emergency veterinary clinic without delay.

Kennel Cough

Dogs may cough up foamy white liquid due to kennel cough or other issues with the upper respiratory system. Although it looks like vomit, the fluids and mucus could come from the respiratory system. Another possibility is that the dog is vomiting fluids and mucous that it swallowed due to the respiratory problem. If your dog is going to vomit white foam, you’ll notice his or her stomach lurching first, distinguishing it from coughing up white foam.

Steps to Take If Your dog throwing up white foam

As a dog owner, you understand how unsettling it is when your beloved pet displays strange symptoms. The sudden appearance of white foam in your dog’s vomit is cause for concern. Feeling anxious is normal, but you can face this challenge head-on if you know what to expect and what to do. This article will go over why dogs may throw up white foam, what you can do to assist, and why taking your dog to the vet is necessary. After going over some of the possible reasons, let’s look at what you can do if your dog throwing up white foam:

First, assess your dog’s overall health. Note any other symptoms, such as fatigue, diarrhea, or stomach pain. With this information, your vet can make a more informed diagnosis.

Keep an eye on your dog’s actions and energy levels. If it keeps throwing up or is distressed, get it to a vet immediately.

Encourage your dog to drink small quantities of water to avoid dehydration. But wait a few hours after the vomiting stops before giving food.

We hope the information we provide is useful, but it’s best to talk to your vet for specific recommendations about your pet’s health.

Methods for Treating White Foam in Canines

Dogs often throw up white, foamy vomit after their saliva and gas have combined in the stomach. You shouldn’t be worried as long as your canine performs normally except for the one episode of white foam in his vomit. You should wait until your dog stops vomiting white foam before giving him his next food. If your dog shows any additional symptoms, such as:

Area of Deficit
Lack of motivation
Lack of hunger
Diarrhea
Vomit with blood
Shaking

More than two times of vomiting in 24 hours or more than a day of intermittent vomiting should prompt you to seek veterinary attention for your canine. If there are any further disease symptoms alongside vomiting, it is essential to consult your veterinarian.

How Veterinarians Diagnose Dog Vomiting White Foam?

A complete physical examination of your dog will be the initial procedure carried out by your veterinarian. Tell the vet everything they need to know about your dog’s current and past health. Be sure to mention any strange things, such as plants, chemicals, or harmful foods your dog may have consumed.

Your veterinarian may suggest additional diagnostic testing to determine the reason behind the vomiting. Imaging studies, such as X-rays and ultrasounds, may be part of this process. This is probable if your veterinarian suspects bloat or an obstruction in your dog’s intestines.

What can you do at home if your dog throwing up white foam

Withholding meals for 12 hours is the recommended course of action for a single episode of white foam vomiting in an adult dog. As a result, the stomach might calm down. After that time has passed, you should feed your pet and observe their reaction. You shouldn’t be concerned if they eat enthusiastically and continue as normal. But you should take them to the vet if they don’t eat or if they eat but then throw up again.

Puppies should not be denied food and water because doing so puts them at risk of dehydration; instead, they should visit the vet as soon as possible. Similarly, it is essential to seek a veterinarian’s advice before depriving your pet of food or water if they have a known medical problem, like diabetes or chronic renal disease.

If your dog shows other symptoms of illness, such as vomiting more than once in 24 hours or vomiting more than 24 hours following the initial episode, immediate veterinary attention is required.

When to Look for Veterinary Assistance?

Seeing a vet right away isn’t always necessary, but if your pet starts throwing up every once in a while, it could be an indication of something more serious. Consider a trip to the vet if any of the following occur:

Continued Vomiting: If vomiting occurs more than once per 24 hours or more frequently than that, it’s important to take your dog to the vet.

Vomiting Blood: Any amount of blood in vomit, whether fresh or digested, is cause for alarm and necessitates prompt treatment by a veterinarian.

Weakness or Lethargy: If your dog seems weak, unresponsive, or sluggish, it needs to be examined and treated immediately.

Seeing your dog vomit white foam is distressing, but you must remain calm and do what is necessary. Your animal friend’s health and happiness are in your hands if you know what to look for and when to take them to the vet. Make an appointment with one of our skilled veterinarians at Best Friends Veterinary Hospital immediately if your dog is throwing up excessively or for an extended period. We are dedicated to giving your pet the loving care they need because their health is our first concern.

Preventing Dogs from Throwing Up and Suffering

Avoiding giving your dog anything it shouldn’t eat, lick, or chew is the surest way to keep it from throwing up. On the other hand, there are situations in which you simply cannot stop your dog from throwing up. Many dogs can pick up and swallow things from the floor faster than you can respond, and illnesses can happen for no apparent reason. Thankfully, you can still take some measures to lessen the likelihood of harm.

Once a year, take your dog in for a check-up at the vet. Limit the amount of treats and stick to a healthy diet.

Keep your dog away from any greenery, sticks, or grass that he might find. Do not let your dog near something that could suffocate him.

Some canines will gladly consume everything they come across on the ground. Before you do anything, learn your dog’s routine.

Put away poisonous substances, including plants, chemicals, and human food.

It is crucial to contact your veterinarian as soon as you notice any symptoms of illness; putting it off will only make matters worse. A veterinarian should see your canine at your earliest convenience if you notice any unusual or concerning symptoms, such as excessive lethargy, diarrhea or vomiting regularly, a complete lack of appetite, chills, or trouble breathing.

Conclusion

In conclusion, a dog throwing up white foam could indicate a problem with its digestive system or lungs. Though many of these conditions are common and manageable, some can be more serious or even life-threatening. Especially in emergencies, it is crucial that you consult a veterinarian without delay if you suspect your dog is ill.
