If your furry friend throws up white foam, there are a few things you can do.

Fast Your Pooch

Let your dog go without food for some time after throwing up. This will allow the stomach time to settle. In most cases, your dog will be throwing up white foam because they have ingested something that is irritating their stomach. You do not want your pooch to eat more of what is irritating so remove all food for 12 to 24 hours.


The next step is to check your pup’s vomit. It may be a little gross, but looking through the vomit can help you figure out what your pooch ate. In some cases, you will find the culprit that may have caused the stomach irritation, such as chunks of food or things such as candy wrappers or dirt.

Check For Other Symptoms

Vomiting can be a symptom on its own, or it can be accompanied by other symptoms. If your dog seems like its usual self after throwing up, then you may not need to worry.

However, additional symptoms like shaking, bloody diarrhea, lethargy, loss of appetite, or swollen abdomen are all cause for concern and require urgent veterinary care.

Try Home Remedies

When your pooch throws up white foam, there are some effective home remedies that can help ease the vomiting. Make sure that you give your pooch plenty of fluids to keep them hydrated.

Vegetable and chicken broth are great options for rehydrating. Ice chips are also good for combating dehydration. You can also give your pooch powder electrolytes to keep them properly hydrated.

How Can I Make My Dog Feel Better After Vomiting?

After your pooch has vomited, you can make them feel better by ensuring that they are not dehydrated.

Vomiting causes the body to lose water, and your pup ends up dehydrated.

Start by giving small amounts of water to your dog. Remember, if you give too much at a time, you may trigger vomiting again.

Powder electrolytes such as Pedialyte can help to replenish lost electrolytes and rehydrate your dog. You can get them from your vet or pharmacy.

Just like the water, electrolytes should be given in small amounts frequently to avoid triggering further vomiting.

You should withhold food from your dog for 12 to 24 hours after vomiting.

After the fast, reintroduce food in small quantities.
