A stomach ulcer is a wound that forms on the inside of the stomach. Often, it’s a side effect of some medications, especially when human painkillers are given to dogs. Some cases can be severe and even life-threatening.

The acid inside the stomach is fundamental for digestion and protection from infections. However, the stomach needs to protect itself from the acid with special secretions and other mechanisms. If something damages these defences, the acid will cause one or more wounds that will struggle to heal. Most stomach ulcers can be treated, but some can cause complications like internal bleeding or peritonitis.
