Intestinal atresia and stenosis is one-third of intestinal obstruction cases in animals and is a common surgical problem in neonates. In human the most common causes of intestinal obstruction in newborns are intussusception and intestinal atresia. The pathogenesis of intestinal atresia in both human and animals is not clear. The present study describes the clinical and histomorphological features of a case of congenital intestinal atresia in a dog. The animal presented with single ileal blind-end atresia combined with the extension of proximal segments of intestines. The distal part of intestines including anus were patent. Histologically intestinal wall congestion and flattening of intestinal villi were noted.
