A diverticulum is a bulging sack that occurs in any portion of the gastrointestinal tract and may be either congenital or acquired. In small animals, intestinal diverticula are rarely reported. Recent literature reports four cases of intestinal diverticula in dog, where two are duodenal diverticula and two are jejunal diverticula. The etiology of intestinal diverticula is unknow. Diagnosis is made by ultrasonography and confirmed during surgery. The treatment for intestinal diverticula is surgical resection. The prognosis is excellent. The clinical case reported in this dissertation was attended at Veterinary Hospital of University of Trás-os-Montes e Alto Douro. A 6-month-old female Beagle was presented with the main complaint of diarrhea with melena and hyporexia over the preceding 4 days. Complementary diagnostic tests showed leukocytosis and hypoproteinemia, presence of foreign bodies in the stomach and small intestine and a highly distended intestinal segment compatible with intestinal obstruction. Medical treatment made followed the standard indications. Surgical treatment consisted on gastrotomy and duodenotomy to remove foreign bodies. During surgery, a jejunal diverticulum was discovered and removed by partial enterectomy with end-to-end anastomosis. Biopsies to the duodenum, jejunum and jejunal lymph nodes were made, as well as a serosal patch before the abdomen was closed. Histologically the diverticulum showed normal appearance and no signs of gastric-type mucosa or pancreatic tissue. The dog was clinically discharged six days after the surgery with no signs of gastrointestinal problems. Seven months after surgery the patient did not present clinical signs of gastrointestinal pathology and recovered corporal condition.
