The vaginal process develops in the embryo as an extension of the parietal peritoneum. Therefore the cavity of the vaginal process is continuous with the peritoneal cavity via the vaginal ring. In the male of all species and the bitch it is possible for abdominal contents (e.g. small intestine or great omentum) to protrude through the vaginal ring and enter the vaginal process. Within the vaginal process the herniated organ or tissue passes through the inguinal canal and may enter the scrotum. An inguinal hernia may or may not be reducible; an irreducible hernia may become strangulated if the blood supply becomes interrupted.

Congenital inguinal hernias are common in pigs, but in sheep they are thought to be a result of trauma. In the horse inheritance has not been proven, but they are more common in certain breeds.
