Perineal Hernia

Perineal Hernia


The anal region of a dog is known as the perineum. Within the abdomen and pelvic cavities are structural linings that provide support and hold organs (intestines, rectum, prostate, bladder) in place. When these organs are able to protrude against that lining, or if the pelvic diaphragm becomes structurally lax, a perineal hernia develops.
