A five-year-old female intact German shepherd presented with an acute onset of abdominal pain. Abdominal ultrasound revealed a 5-cm encapsulated, heterogeneous structure with hypoechoic patches near the right pancreatic lobe. An exploratory laparotomy revealed a partially encapsulated necrotic mass located at the greater omentum. A partial omentectomy was performed. Histopathological findings were consistent with necrosis of the omentum secondary to omental torsion. Postoperative course was uneventful. Omental torsion is a rare cause of abdominal pain in human beings and animals. In veterinary medicine, it has only been reported four times, none of them in a dog. Omental torsion should be included as a differential diagnosis for dogs with acute abdominal pain and gastrointestinal signs. Imaging studies can aid in the diagnosis but exploratory laparotomy is probably the best diagnostic and therapeutic intervention in these cases. Prognosis after surgery appears to be good but an underlying aetiology should be searched thoroughly.
