What Should I Do If I See White Foam On My Dog’s Mouth?

Seeing your dog vomit is far from a pleasant sight, but if you ask just about any dog owner out there, it’s not an uncommon sight either.

Dogs are curious beings. They are constantly putting things in their mouth that they shouldn’t and finding themselves in less-than-ideal situations. And when your dog eats something, they shouldn’t, one of the common side-effects are vomiting.

White Foam On My Dog’s Mouth

This could happen because they’re trying to expel the substance, they ate something toxic, and a bunch of other things.

But what do you do if there’s white foam in your dog’s vomit?

The first thing to do is not panic. White foam in your dog’s vomit can mean a lot of things, but it’s usually just gastric juices or saliva. This is natural and isn’t any reason to freak out. Whenever your dog vomits, the best thing you can do is observe them.

In this guide, we’ll be going through exactly what to do if you see white foam in your dog’s vomit, what it means, and how to keep it from happening.

What Does White Foam In a Dog’s Vomit Mean?

One of the most common causes of a dog throwing up white foam is saliva. Most of the time, the white foamy substance on top of your dog’s vomit is just saliva mixed with air and is nothing to worry about. Other times, the white foam could be gastric juices from your dog’s stomach that came up along with the food.

If this happens just once, there’s no reason to panic. However, in the event that your dog throws up white foam every day or it’s happened a couple of times, there might be other underlying causes. In this case, the best solution is to call the vet as they will know exactly what to do.

What To Do When You See White Foam In Your Dog’s Vomit

If you notice white foam in your dog’s vomit, while not a cause of panic, can be concerning. Here’s what you have to do whenever your dog throws up white foam:

Examine the Vomit

The first thing to do is take a look at the vomit. Along with the white foam, what else did you notice? What other colours were present? Did you see any debris and other things in the vomit? All of these things can be indicators of why your dog is vomiting and would be crucial in describing your dog’s condition to the vet.


Once you’ve examined and cleaned up the vomit, it’s time to observe your dog. Try to note if they vomit again, how they are acting, and whether or not there are other symptoms they’re exhibiting such as diarrhoea or lethargy. It’s also helpful to try and remember what your dog may have been doing the past couple of hours. Were they in a place where they could have eaten something they shouldn’t have? The answer to this question could determine why your dog is vomiting in the first place.

Call Your Vet

If your dog vomits once and doesn’t do it again, there’s no reason to call the vet. Your dog probably threw up because they ate something shouldn’t have, ate too fast/much, or they could have run around too much after eating.

However, if they vomit more than once and it’s accompanied by other symptoms, that’s when you should call your vet. Since your vet knows your dog and its conditions, they should be able to easily figure out what to do and whether your dog needs medical attention.

Either way, if symptoms persist, make sure to schedule an appointment as soon as possible.

How to Keep Your Dog From Vomiting White Foam

You can’t keep your dog from vomiting. There are simply too many things that can cause your dog to vomit white foam to prevent all of them. However, you can do some things to reduce the chances of it happening.

The best thing you can do to keep your dog from vomiting is to make sure they don’t eat anything they shouldn’t. So, if your dog spends a lot of their time in the gardens, train them not to eat the grass or other plants. This goes the same for just about anything that isn’t their dog food or treats.

Additionally, making sure your dog is fully vaccinated and eats a healthy diet is a great way to prevent vomiting. Remember, you can never fully prevent vomiting and other sicknesses, but you can reduce your chances of it happening to your dog by making sure they live a healthy life.


If your dog is vomiting white foam, don’t panic. There are a number of things that can cause it, and most of the time, it’s nothing to worry about.

Just keep an eye on your dog and if symptoms persist or are accompanied by other symptoms like lethargy or diarrhoea, contact your vet and schedule an appointment immediately.
