title: Non-rotated midgut in a dog.
abstract: Macroscopic observations of the partly-dissected abdomen of the preserved cadaver of a Labrador bitch were recorded and photographs taken. Neither the duodenum nor the colon looped around the root of the great (jejuno-ileal) mesentery, but both were long enough to have done so. The abdominal organs appeared to be otherwise normal, as did the other parts of the body. The condition appeared to have resulted from non-rotation of the midgut during embryonic development and to have no adverse effect on the animal.
