Have you noticed your dog vomiting white foam? It can be a very concerning sight for pet owners, seeing their furry best friend in such discomfort, but it happens to a lot of dogs out there.

Your dog throwing up white foam can be caused by various things, such as ingesting rotten food or eating a foreign object. Whatever the reason, it’s always best to act fast to prevent any further health complications.

In this article, we’ll be going through a couple of things you should do if your dog starts vomiting white foam.

Read on to learn more.

What Causes Dogs to Throw up White Foam?

As we mentioned earlier, there can be many reasons a dog will throw up white foam. The most common cause, however, is gastrointestinal (GI) distress. When a dog experiences indigestion and has nothing left to expel in its stomach, it may start throwing up white foam. Excess gas in the gut can also cause this.

GI in dogs is usually caused by ingesting something that shouldn’t be eaten. This can be rotten food, garbage, grass, or any foreign object.

However, there are times where a dog throwing up white foam can be a symptom of something more serious. These include:

Kennel Cough

Kennel cough, also known as tracheobronchitis, and it’s a highly contagious respiratory disease. Vomiting is one of the symptoms of kennel cough and is usually accompanied by sneezing and a strong cough.


Parvovirus is a severe viral infection that is frequently seen in puppies and can be fatal. A dog can contract parvovirus through oral contact with feces, and the symptoms include vomiting, diarrhea, and a bloody stool.

Luckily, most dogs develop immunity to parvovirus through early vaccination.

Vomiting may also signify other serious issues such as acid reflux, fungal infection, kidney problems, pancreatitis, and tracheal collapse.

What to Do if Your Dog Throws up White Foam

As vomiting white foam can be caused by many things, including severe health conditions, the primary thing to do if you notice your dog vomiting white foam is to bring them to the vet.

If you only notice your dog throw up once, that isn’t a cause of concern yet. This is because the vomit might just be caused by your dog ingesting something they shouldn’t have, such as grass. But if you notice that your dog has thrown up white foam twice within 24 hours, the best decision is to bring them to the vet.

A veterinarian can quickly diagnose the cause of your dog’s vomiting and recommend treatment plans that are safe and effective for your dog.

How to Prevent Vomiting in Dogs

While, at times, it can be impossible to prevent these things from happening, there are some things you can do to reduce the risk.

First, make sure to bring your pet to the vet for a check-up annually. This will need to be done for all pets so that you can keep a constant tab on the state of the animal’s health. And if your vet recommends bringing your dog over more frequently, it’s best to follow their advice.

Secondly, make sure that your dog is eating a healthy diet. This means giving it the proper nutrients and food it needs while keeping treats down to a minimum. Feeding your dog properly also means preventing it from chewing on grass and eating things they shouldn’t like garbage or rotten food.

Lastly, make sure to keep foreign objects out of your dog’s reach. A lot of dogs will be happy to eat anything they find lying around on the floor. Make sure to keep foreign objects in a drawer or place a dog won’t reach.
