Abstract

A clear understanding of the pulmonary morphology of domestic animals is essential for the recognition and investigation of any anatomical variations. The right and left lungs of small ruminants and dog are separated into distinct lobes by inter lobar fissures. The right lung in these animals typically divides into 5 and 4 lobes, respectively. However, the left lung divides into 3 lobes. We report a case of congenital absence of the middle lobe of the right lung of a sheep and extra lobation in the left lungs of two dogs in Trinidad. This case report is of value to veterinary radiologists, pathologists, and veterinary public health inspectors during examination and investigation of the thoracic cavity of the sheep and dog.
