Acute gastritis is the sudden and often severe inflammation of the stomach lining. It is one of the most common causes of vomiting in dogs and cats. While often caused by dietary indiscretion (eating garbage, spoiled food, or foreign objects), it can also result from toxins, infections, or metabolic disorders.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpThe condition itself is not typically contagious. However, if the underlying cause is an infectious agent like a virus or bacteria, that agent may be transmitted through direct contact or shared bowls.
The condition typically presents with an acute onset of vomiting. If untreated, it can progress to dehydration and electrolyte imbalances. Recovery is usually rapid with appropriate supportive care.
Diagnosis is primarily based on the patient's history and physical examination. X-rays or ultrasound may be performed to rule out foreign body ingestion or obstruction. Blood tests help evaluate hydration and rule out organ failure.
Treatment focuses on resting the stomach (brief fasting), providing a bland diet, and administering anti-nausea medications such as maropitant (Cerenia) or ondansetron. Fluid therapy is essential if the animal is dehydrated.
Prevention involves preventing access to garbage, table scraps, and potential toxins. Feeding a consistent, high-quality diet and avoiding sudden food changes can also reduce risk.
The prognosis is generally excellent for simple cases treated early. However, if caused by a toxin or foreign body, the outcome depends on the severity of the underlying issue.
