It is pretty common for dogs to vomit every now and then. And there is absolutely no reason to be overly alarmed if your dog starts to spew white foam. The only you need to do is take the initiative which means looking into what’s causing it and coming up with a solution.
Discover the common causes and remedies for white foam vomit in dogs by reading on.

6 reasons your dog might be vomiting white foam
1. Food Poisoning
One of the frequent reasons for white foam vomit in dogs is eating hazardous food. Dogs need to be treated with extra care when eating because of their delicate stomachs.
After consuming something that makes their stomach unhappy, your dog will quickly want to get it out of its system. This may cause them to vomit white froth.
If you do see your dog vomiting white foam, check to ensure that they are not allergic to something they're being fed or that their food and water have not been contaminated.
2. Gastrointestinal Blockage
Another possible explanation for your dog's vomiting white foam is that they consumed something too large for them to digest or pass down their esophagus properly.
When playing, dogs frequently chew socks, toys, and other significantly sized objects. It's also possible that they ate large bones or maize cobs.
Consequently, your dog may start vomiting white foam to get rid of these foreign objects if they get caught in their intestines, stomach, or esophagus.
3. Respiratory Diseases
Canine Infectious Respiratory Disease, or as it is more often called, Kennel Cough, Lung Fluke, and Canine Influenza, among other ailments, can occasionally clog a dog's respiratory tract, resulting in a violent cough.
Your dog may start to create white foam when this coughing persists.

4. Change in diet
Dogs' sensitive stomachs, as previously mentioned, call for caution while choosing their diet. Any dietary changes could have an effect on how your dog feels internally.
You might have adjusted your dog's diet or made a few other nutritional modifications that could cause it to spit up white foam.
Ensure your dog isn't allergic to anything they consume, or keep them on a diet to be safe.
5. Gastric Dilatation and Volvulus (GDV)
Like us, dogs frequently experience stomach bloating. However, bloating in dogs can indicate a more serious condition and often results in Gastric Dilatation and Volvulus (GDV).
This is when a dog's stomach fills with air, twisting and floating as a result and obstructing the flow of blood to the spleen and stomach. This can be pretty uncomfortable and even agonizing at times and could cause the dog to throw up white foam.
6. Parasites
Parasites such as lungworms and heartworms live in dogs' respiratory systems and can wreak havoc on their airways. These parasites can infect your dogs through contaminated food or water. Parasites, while not hazardous, could cause your dog's white foam vomiting.

After determining the cause of your dog's white foam vomiting, the next step is administering treatment. But how?
The kind of treatment you will adopt depends on the cause of the dog's vomiting and how frequently it happens. Ascertain how often your dog vomits white foam if you have noticed them doing so and have located the cause.
You should keep an eye on your dog for at least 12 hours to decide whether there is a serious problem or whether your dog is just experiencing mild stomach discomfort
Keep an eye out for any other symptoms, such as dysentery, tiredness, decreased appetite, and so on.
1. Home Therapy
If the only symptom is a slight stomach ache or there are none at all, you can try home therapy.
Put a stop to any food or water intake to allow your dog's stomach to settle.
Also, keep an eye on your dog's feeding and make sure everything they consume is clean and healthy. To be safe, you might also include routine doctor checkups.
2. Visit the Vet
You should take your dog to the vet immediately if, after observation, you notice that it is displaying further symptoms and the vomiting is persistent. Your dog could be experiencing a more severe issue that needs immediate medical attention.
Conclusion
If your furry companion starts vomiting white foam, you can see that there's no reason to panic. You can quickly get them back in shape once you can determine the source and immediately put countermeasures in place.
