Pectus excavatum is considered a pathology of the chest wall where there is convexity in the ventral aspect of the sternum, which generates secondary complications, such as ventrodorsal stretching of the chest and increased intrathoracic pressure, among others. In the present case, the body of a French bulldog dog was born with previous signs of decay and low consumption of maternal waste, in addition to a forensic medical evaluation. According to the pathological evaluation, a crack was found in the sternal chest related to the caudal sternum close to the xiphoid cartilage, frothy content in the laryngeal epiglottis cartilage and severe signs of emphysema in the caudal, cranial and middle lung lobes. In the cardiological evaluation, an invaginating morphological asymmetry was observed in the interventricular septum in the same area in which the sternal cleft occurs, in turn, in the radiographic evaluation, it shows a dorsal depression of the caudal third of the sternum with considerable changes in the cardiac silhouette. In Colombia there are no reports of complete litters that present this alteration, so it is intended that this is the first anatomopathological and imaging report that describes the pathology in canines.
