Stomach ulcers in dogs are sores or lesions that form in the lining of the stomach, which protects the organ 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 of stomach ulcers in dogs, and though ulcers are usually treatable, 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 the signs of a stomach ulcer in your dog, you should consult your veterinarian immediately so they can form a diagnosis, determine any underlying causes, and form 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 has perforated the wall of the stomach, for example, dogs may require surgery.

If a dog has suffered from dehydration due to vomiting and diarrhea, intravenous fluids may be needed to restore hydration and electrolytes. Veterinary treatment will also focus on the underlying cause of the stomach ulcer.

Veterinarians will usually prescribe an antacid medication to reduce the level of stomach acid and allow the ulcer to heal. They will 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 antibiotics will be prescribed.

There are several natural treatments for ulcers, as well. Many dog owners 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 should ask your veterinarian about these treatments before offering them to your dog.
