Thirty seven intact male dogs were presented by perineal hernia. Nine of them were suffered from bilateral (24.3%) and the remaining cases were unilateral condition (75.7). All cases were subjected to repair of the perineal hernia, standard herniorrhaphy (28cases), implantation of polypropylene mesh (8cases), and placement of tension band (3cases). Recurrence was recorded in two cases 4 months after initial surgical intervention. Castration was performed in 32case and the other five cases were not castrated according to the owner judgment. Follow up of the previous cases were undertaken. Both sides of bilateral conditions and simultaneous castration were operated at same time. Perineal hernia mostly suspected clinically and confirmed by radiographic assessment. In our study, we are review the etiology, clinical signs, radiographic picture, postoperative complications and synthetic hernioraphy to aid in the successful closure of the pelvic diaphragm.
