Possible Causes of Stomach Ulcers in Dogs

Pug 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 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.

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.
