perineum

the region between the tail and the ischiatic arch, especially the region between the anus and genital organs made up of the pelvic diaphragm and associated structures occupying the pelvic outlet, bounded ventrally by the pelvic symphysis, laterally by the ischial tuberosities, and dorsally by the coccygeal vertebrae. During parturition the perineum may be torn, resulting in possible damage to the urinary meatus and anal sphincter. To avoid a perineal laceration the veterinarian may cut the perineum just before delivery and suture the incision after delivery. See also episiotomy, perineorrhaphy.
