Dog Throwing Up White Foam – 9 Reasons Why and What To Do

If your dog is throwing up white foam, it may be time to take him to the vet. Here are some causes and solutions for white foam vomiting in dogs.

Why is my dog throwing up white foam?

Dogs are prone to vomiting just like humans. As a pet parent, your dog’s vomiting can be really upsetting. If you are concerned about your dog throwing up white foam, you’ve come to the right place.

Dogs vomit due to multiple reasons. Their vomit can often appear green, yellow, white, or even foamy. While the reason your dog vomited white foam
may not always be concerning, it’s almost always certainly worth exploring.

If your dog has only had a single episode of throwing up white foam, it might not be that concerning. 

However, you might need to rush your dog to the nearest vet if your dog vomits white foam frequently, or has had multiple episodes in a single day!

Here are some of the most common reasons why dogs vomit white foam. Read more below to find out how concerned should you be if you find your canine making belching noises and throwing up behind the couch.

9 reasons why dogs throw up white foam

As mentioned before, dogs vomit white foam due to multiple reasons. Frothy white vomit can be caused by infections, GIT (gastrointestinal tract) obstructions, toxins, and even an upset stomach!

Here are some of the most common reasons why your dog can’t stop throwing up.

1) Indigestion

Indigestion is the most common cause of throwing up in many animals. Dogs like to sniff around for food in the trash and other unhygienic places. Most of the time, the food they find does not end up agreeing with their gut.

An upset stomach can cause your dog’s gut to move in the opposite direction, causing everything to come out from the mouth. 

This is usually not a huge problem and most dogs feel fine instantly after throwing up whatever caused indigestion in the first place.

2) Acid reflux

If your dog vomits white foam before breakfast, this may be due to excessive acid or bile salts in the stomach. Both the acid and the bile salts can irritate the lining of your stomach, causing projectile vomiting.

Vomiting due to acid reflux is also very common in dogs and this is usually resolved by giving the dog small but frequent meals throughout the day.

3) Pancreatitis

Pancreatitis is one of the most serious causes of vomiting white foam in dogs.

Pancreatitis refers to inflammation of the pancreas, which is an emergency condition. typical symptoms of pancreatitis, other than vomiting, include diarrhea and a complete lack of appetite.

4) Gastrointestinal inflammation

Inflammation of the gut lining, regardless of where its located, can cause the food to travel in the reverse direction and cause vomiting in dogs.

If your dog keeps throwing up white foam, it might have an active inflammatory lesion in any part of its small or large intestinal tract.

5) GIT obstruction

If your dog keeps projecting white foamy vomit, remains irritable, curls up on the floor, and seems in intense pain, it might have a gut obstruction.

A gut obstruction at any point in the GIT can block the normal passage of food. Food starts accumulating behind the obstruction. 

Once enough pressure is built up, your dog may throw up in a projectile manner, i.e. throwing up in an explosive manner.

GIT obstructions are an emergency condition and any dog with multiple episodes of projectile vomiting should be rushed to the nearest vet.

6) Toxins

White foam vomitus can also occur if your dog eats any toxic material lying around the house, such as medications, expired food, cleaning supplies, and other such materials.

Other symptoms that appear after a dog ingests something toxic include weakness, trembling, and fever.

7) Rabies

Infections are notorious for causing vomiting. Rabies infection, while rare in the United States, can cause nausea and bubbling in the mouth that appears similar to a collection of white foam.

8) Overeating

A dog’s stomach can only accommodate so much food, and when dogs overeat it usually results in white foam vomit. Overeating also contributes to a majority of dog vomit cases every year in the United States, as well as around the world.

9) Kennel cough

Kennel cough and other respiratory infections can lead to excessive foaming and even white foam vomit.
