Have you seen a dog vomiting white foam? This phenomenon can be a very strange and distressing one. This can cause you to have questions concerning your dog's health status. This is why you need to know the potential causes of your dog vomiting white foam and when to seek veterinary care. 

This guide will help you understand the potential reasons behind this vomiting. It will also help you to differentiate between minor and serious causes, and know when to seek veterinary care.

Vomiting in Dogs

Vomiting in dogs occurs when the stomach forcefully pushes its contents up and out through the mouth. This can happen for various reasons like eating something bad, having a stomach infection, or feeling very anxious or stressed. It is a way for the body to get rid of something that it thinks is harmful.

Causes of White Foam Vomiting in Dogs

Empty stomach

This is a common cause of your dog vomiting white foam. Dogs sometimes throw up white foam because their stomachs have been empty for too long. Gastric acids that irritate the stomach lining are produced when their stomach has been empty for a while. Then they vomit white foam which is a mixture of saliva and gastric juices. This is often called the "hunger puke" and can occur if there is a long gap between meals.

Gastrointestinal issues

Gastrointestinal (GI) issues are discomforts in your dog's stomach that occur when your dog eats something that is not normally supposed to be ingested or that their body is not used to.

GI issues can come in many forms. For example, irritable bowel syndrome, gastritis (acute or chronic inflammation of the stomach lining), nausea, and vomiting. These issues can also come from your dog ingesting an unhealthy meal or even taking something they are allergic to.

GI issues can also be caused by microorganisms like viruses or bacteria or even a health condition.

Bloat

Bloat, also known as gastric dilatation-volvulus (GDV) can be fatal in dogs if not treated in time. GDV happens when a dog's stomach fills with food and gas, and then twists on itself. This twist traps the contents inside and cuts off blood flow, making it a medical emergency.

One of the symptoms of bloat is retching and vomiting white foam. Other signs include a swollen or distended abdomen and restlessness. Bloat requires immediate veterinary attention to save the dog's life.

Eating grass

Grass on dog’s vomit

Sometimes, dogs eat grass to make themselves vomit or help their digestion. When they eat grass and then vomit, it might look like they are vomiting white foam mixed with grass particles. This behavior is usually not harmful unless it becomes excessive or is accompanied by other symptoms. If you notice your dog eating grass frequently and vomiting often, it's best to consult with a veterinarian to rule out any underlying issues.

Pancreatitis

Pancreatitis is the inflammation of the pancreas. This condition can be the cause of your dog vomiting white foam. This is a serious condition and requires prompt medical intervention. Other symptoms include abdominal pain, lack of energy, and loss of appetite.

Parvovirus

Parvovirus is a contaminable viral disease that affects puppies and unvaccinated dogs. It can cause  severe vomiting , often accompanied by white foam, diarrhea, and lack of energy.

Parvovirus is a medical emergency that requires immediate veterinary care.

Infectious bronchitis

Infectious bronchitis can also be called kennel cough. It results from inflammation of the trachea. This contagious disease of the respiratory tract will cause your dog to cough and sometimes vomit white foam. It can also occur if your dog has been to the groomer, boarding facility, or dog park.

Kennel cough presents with a persistent dry cough and vomiting which occur because of throat irritation.

Other causes of white foam vomiting in dogs include bilious vomiting syndrome (when bile from the small intestine leaks into the stomach acids), internal blockage, kidney disease that causes blockage, inflammatory bowel disease (IBD), and internal parasites.

Parvovirus is a medical emergency that requires immediate veterinary care.

When to Seek Veterinary Care

Persistent vomiting

If your dog continues to vomit white foam for a long time with added symptoms like loss of appetite or diarrhea, it is important to consult a vet. Persistent vomiting can lead to dehydration and may indicate a more serious underlying issue.

Signs of bloat

As mentioned earlier, bloat is a critical condition that requires immediate attention. If your dog shows signs of bloat, such as a distended abdomen, restlessness, or retching, please seek emergency veterinary care urgently.

Blood in vomit

If you notice blood in your dog’s vomit, it could be a sign of a severe gastrointestinal issue, ulcer, or internal injury. Blood in vomit is always a red flag and requires prompt veterinary evaluation.

Other symptoms

Dogs that throw up white foam may have an underlying disease. Other symptoms like excessive drooling, weakness, pale gums, difficulty breathing, or collapse indicate that your dog needs immediate medical attention.

Treatment

Treatment for your dog throwing up white foamy stuff will depend on the cause. The following are some common treatments.

Dietary changes

If you notice your dog throwing up white foam because of minor gastrointestinal issues or hunger pukes caused by regurgitating stomach acids, adjusting their feeding schedule or diet can help. Providing smaller, more frequent meals prevents an empty stomach and reduces gastric irritation.

Medications

If the cause of vomiting is an underlying condition like gastritis, pancreatitis, or even kidney disease, your vet may prescribe medications to reduce inflammation, control nausea, and manage pain. Antibiotics may be needed if an infection is present.

Medication for dogs vomiting white foam

Fluid therapy

When your dog vomits persistently, it can result in dehydration. In cases like this, fluid therapy may be administered to rehydrate your dog and restore electrolyte balance.

Surgery

In severe cases, such as bloat or gastrointestinal obstructions, surgery may be necessary. Surgical intervention will correct the issue and prevent further complications.

Supportive care

For conditions like parvovirus or kennel cough, supportive care is crucial. This includes maintaining hydration, providing a comfortable environment, and monitoring for secondary infections.

Prevention

While some causes of vomiting cannot be avoided, there are measures you can take to prevent it from happening.

Proper diet

Ensure your dog is on a balanced diet suitable for their age, size, and health needs. Avoid sudden changes in diet and do not give them table scraps or foods toxic to them. Also, avoid foods they are allergic to. To be on the safe side, you can feed your dogs healthy chews like the Super Health Vitality™ Chews

Regular vet check-ups

Regular veterinary check-ups help detect and address potential health issues early. Keep up with vaccinations and parasite control to prevent infectious diseases.

Safe environment

Ensure your home and yard are free from potential hazards such as toxic plants, chemicals, and small objects that your dog might ingest. Supervise your dog during walks to prevent them from eating something harmful.

Gradual feeding schedule

If your dog tends to vomit due to an empty stomach, feed it smaller, more frequent meals throughout the day. This can help maintain a more consistent level of stomach contents and reduce the risk of vomiting. An all-inclusive meal like the Primal-Vitality™ Beef Organ Complex may solve and even prevent digestive issues.

Avoid overexertion

Avoid strenuous exercise immediately after meals as this can increase the risk of bloat. Allow your dog to rest and digest their food before engaging in physical activities.

Conclusion: What Does It Mean if a Dog Vomits White Foam?

Your dog throwing up white foam can be a symptom of various conditions, ranging from minor to severe. Understanding the potential causes and knowing when to seek veterinary care is important for your dog’s health and well-being. While occasional vomiting may not be a cause for alarm, persistent and severe symptoms warrant prompt medical attention. By providing a balanced diet, maintaining a safe environment, and ensuring regular vet check-ups, you will minimize the risk of white foamy vomit from a dog and keep your pet healthy and happy.
