Possible Causes of Stomach Ulcers in Dogs

Stomach Ulcers in Dogs The most common causes include:

  • Conventional anti-inflammatory medications prescribed for skin conditions, arthritis, or other chronic health problems, such as NSAIDs, corticosteroid, can cause canine ulcers.
  • Conventional medicines for pain relief, such as aspirin and ibuprofen, inhibit a hormonelike substance that acts as a protection for the stomach lining. Prolonged use of these medications, therefore, can also cause stomach ulcers in dogs. Sometimes the condition can be serious. (Although buffered aspirin is said to be gentler and easier on the stomach, it can still lead to dog ulcers.)
  • Another cause of canine stomach ulcers is mast cell cancer in the skin. Cancerous mast cells release histamine which leads to stomach ulcers.

Other less common causes include:

Diagnosis and Treatment

Physical examination and tests may include:

  • Blood tests

  • Feces analysis
  • Ultrasonography
  • Endoscopic examination

Conventional treatment include diet change and antacid medications to coat the stomach lining.

Depending on the conditions of the dog, medicines for diarrhea and vomiting may also be described.

Preventing and Controlling Ulcers in Dogs

As always, prevention is better than cure. If your dog has a weak digestive system, and is showing signs of ulcers, such as vomiting and diarrhea, take action quickly. Use the remedies recommended above to nip the problem in the bud. Also, try doing the following:

Feed the Dog More Frequently

Just like people with ulcers, dogs with ulcers also benefit from having more frequent meals in smaller portions. If your dog is fed only once or twice a day, stomach acids have more chance to irritate the dog's stomach. Divide the food into smaller portions and feed your dog three or four times a day instead.

Reduce Stress

Stress in itself may not cause ulcers in dogs, but if a dog with ulcers is under a lot of stress, his condition may get worse. It is therefore advisable to provide a calm, loving, and stress-free environment for your dog.

Stop all Ulcer-Causing Medications

As mentioned above, the most common cause of ulcers in dogs is conventional anti-inflammatory medications and pain-killers. If your dog is suffering from arthritis or allergies, and is in need of long-term medication for allergies or pain relief, try using some gentle natural pain relief or natural remedies for allergies.

Natural Remedies for Stomach Ulcers in Dogs

To effectively to deal with canine ulcers, herbs and other supplements can be used to:

  • treat the ulcers and accompanying symptoms in a more gentle way;
  • improve and strengthen the immune system of the dog.


Herbs that can soothe, coat, and help rebuild the stomach lining are effective in treating ulcers:

  • Licorice root: This herb stimulates cell growth, helps protect the stomach's walls, and alleviates ulcers. (Dosage: 100 to 300 mg depending on the size of the dog, up to one week.)
  • Slippery elm: This herb soothes, lubricates and protects the stomach walls and digestive tract, and is ideal for treating ulcers. (Dosage: 1/2 teaspoon to 1 tablespoon depending on the size of the dog, 3 times a day. Use the powdered form of the herb and mix it with warm water until it forms a paste.)
  • Aloe vera: The juice of this herb prevents nausea and help ulcers heal faster. (Dosage: one to two teaspoons of the juice once a day can be added to the dog's drinking water.)
  • Alfalfa: This herb is anti-inflammatory, and supports the rebuilding of mucous membranes. Alfalfa is known to balance hyperacidity in the digestive tract and has been traditionally used for digestive ailments.
  • Astragalus/Echinacea: These herbs are immune-booster and can strengthen the overall health of a dog.


  • L-glutamine: This is an amino acid that is effective for protecting and healing mucous membranes, such as the lining of the stomach. It also prevents the formation of stomach ulcers.
  • Quercetin Chalcone: Quercetin is a bioflavonoid and it has antihistamine, anti-inflammatory and antioxidant properties. Quercetin Chalcone, a form of Quercetin, can inhibit bacterial growth in the stomach and may be helpful in preventing stomach ulcers.

Home Remedies for Ulcers in Dogs

For ulcers that are not deep (superficial), try these home remedies:

  • Manuka Honey: Manuka honey from New Zealand is the "king" of honey. It is rich in antioxidants and flavonoids, and is known to be highly anti-bacterial, anti-viral and anti-fungal. It can kill Helicobacter pylori bacteria, which causes stomach ulcers. It also has inflammatory-properties.

    In a study, it was found that Manuka honey had anti-ulcer properties and worked well against ulcers in rats.

    Try giving a teaspoon to a tablespoon (depending on the size of your dog) to your dog every day. Be sure to get Manuka with a UMF of at least 10+.

  • Cabbage Juice: Research has shown that cabbage juice facilitates rapid healing of stomach ulcers in people.

    It's no wonder if you look at what's in the cabbage juice. It's rich in the amino acid L-glutamine and the compound gefarnate, both of which are effective in nourishing the lining of the GI tract. Cabbage is also rich in S-methylmethionine, which has anti-ulcer properties.

    You can of course make the cabbage juice yourself, or if you don't have time, take a look at this:

    This cabbage extract is easy to use: just add 1/4 teaspoon of the powder to a glass of water and give it to your dog with meals.
