Danger level 3


The primary symptom of an acute gastritis is constant vomiting that lasts for several days. Appetite is usually reduced. The general condition can be impaired but doesn't have to be in all cases.

In case of multiple gastric bleedings the vomit might be interfused with bloody streaks (without prior feeding) or look black rather than red (with prior feeding, also known as "coffee ground" vomit). Affected dogs often eat a lot of grass and yawn more frequently. If the acute gastritis is not complete healed it can become chronic.

With the secondary gastritis, a dysfunction of another organ (system) exists, which also affects the craw. Particularly liver and kidney disorders, but also stress conditions, circulatory problems and metabolic disorders (e.g. diabetes mellitus) may play a role here.

Otherwise the diagnosis of gastritis can be made with the aid of the method of elimination. For light diseases, in many cases spontaneous remission after feed reduction or withdrawal is possible. These measures should, however, not be taken by the owner itself, but always in consultation with a veterinarian. In more severe cases and with secondary gastritis, a medicinal treatment is indispensable. Particularly anti-inflammatory drugs and antibiotics may have an advantageous effect here.
