A number of factorscontribute to the development of perineal hernias.
Genetic selection for low muscle mass in the rump area and male hormone
influences are involved.
Environmental factors can play a role such as exercise and sudden impacting
pressure to the abdomen.
Animals who have suffered trauma such that the intra-abdominal pressure
suddenly rises can force abdominal contents through a body wall and into
areas outside the abdomen.
