  Bilious Vomiting Syndrome (BWS) is a condition associated with the patient's vomiting characterized by bile in the early morning hours. BWS (reflux gastritis/duodenal gastric reflux) is a common disease that develops due to biliary reflux from the duodenum to the stomach and is characterized by chronic and intermittent bile vomiting [1-3]. Vomiting is thought to occur as a result of irritation of the gastric mucosa as a result of reflux of duodenal fluid into the lumen of the stomach. Although the cause is unclear, the primary underlying cause is thought to be gastric hypomotility. No age, race or gender predisposition is reported in the disease. It is mostly observed in the middle-aged dogs [1,3,4]. The disease is mainly symptomatic in dogs that have not received food in the morning and during the night. It is characterized by chronic and intermittent bile vomiting. These dogs have an empty stomach and gastric bile reflux is observed. Body condition of the patients is generally normal. Bile salts cause damage to the gastric mucosal barrier over time, leaving the gastric mucosa unprotected against gastric acid. In dogs with bilious vomiting syndrome, gastric bile reflux and irritation of bile on the gastric mucosa lead to the development of gastritis over time [1].
