Can Dogs Develop Stomach Ulcers? Signs & Causes Explained

Stomach ulcers, also known as gastric ulcers, are painful sores that develop on the lining of the stomach. While commonly associated with humans, dogs can also develop stomach ulcers, which can significantly affect their health and quality of life. Understanding the signs, causes, and treatment options is crucial for any dog owner.

What Are Stomach Ulcers in Dogs?

Stomach ulcers in dogs are lesions that form when the protective mucosal lining of the stomach is damaged, allowing stomach acid to erode the tissue beneath. This can lead to pain, bleeding, and digestive issues.

Common Causes of Stomach Ulcers in Dogs

Cause	Description
Medications	Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids can irritate the stomach lining.
Stress	Physical or emotional stress can increase acid production, leading to ulcers.
Infections	Certain bacterial infections, such as Helicobacter pylori, may contribute to ulcer formation.
Chronic Diseases	Conditions like kidney or liver disease can predispose dogs to ulcers.
Dietary Factors	Poor diet or ingestion of toxic substances can damage the stomach lining.

Dietary Management: Feeding bland, easily digestible food to reduce stomach irritation.
Addressing Underlying Causes: Managing stress, adjusting medications, or treating chronic diseases.
