The perineum is the part of the body wall that occludes the caudal opening of the pelvic cavity; it surrounds the anus and the urogenital opening. The major portion of the perineum, comprising the levator ani and coccygeus muscles, is called the pelvic diaphragm. A hernia through the pelvic diaphragm can occur as a result of a defect in the musculature. This is a fairly complex anatomical area including the external anal sphincter, superficial gluteal muscle and sacrotuberous ligament.

Perineal hernias occur mainly in older male dogs and certain breeds, e.g. the Boxer, Boston Terrier, Pekingese and crossbreds.
