Stomach ulcers in dogs are sores or lesions that form in the lining of the stomach. The lining protects the stomach from damage caused by gastric acid that aids in digestion.

Signs of stomach ulcers in dogs often include abdominal pain, loss of appetite, and weakness among other symptoms.

There are many possible causes, and though vets can usually treat ulcers, there are some extreme cases where an untreated ulcer can lead to anemia or perforations in the stomach that cause sepsis, shock, or even death.

If you see symptoms in your dog, you must consult your veterinarian right away so they can form a diagnosis, find any underlying causes, and prescribe a treatment plan. Here’s what you should know about the symptoms, causes, and treatments for stomach ulcers in dogs.

Treatment for stomach ulcers in dogs often depends on the severity of the condition. In cases where the ulcer perforates the wall of the stomach, for example, dogs may require surgery.

Dogs who suffer from dehydration due to vomiting or diarrhea may need intravenous fluids to restore hydration and electrolytes. Treatment will also focus on the underlying cause of the ulcer.

Vets usually prescribe antacid medication to reduce stomach acid and allow the ulcer to heal. They’ll also likely prescribe dietary changes. Dogs who have stomach ulcers should stick to low-fat, bland foods so they can heal and prevent more ulcers from forming.

If there is a bacterial cause of the ulcers, then vets will prescribe antibiotics.

Some pet parents try natural treatments for ulcers, as well. They may use licorice root, aloe vera, slippery elm, echinacea, or alfalfa. Certain supplements such as L-glutamine and quercetine can also strengthen the immune system and prevent new ulcers from forming.

You must ask your vet about these treatments before offering them to your dog.
