A 5-year-old castrated male Chihuahua weighing 1.8 kg was presented for examination of a right perineal swelling. No clinical signs other than the swelling were observed by the owner. Digital palpation to the swelling confirmed right reducible perineal herniation. Dorsal perineal hernia was observed during surgery. A modified internal obturator transposition combined with a modified traditional perineal herniorrhaphy was performed for the perineal hernia repair. Contralateral herniation involving fat was noted a month after surgery. Coexistence of sciatic, dorsal, and caudal perineal hernias was observed during surgery. Aforementioned herniorrhaphy was performed for the perineal hernia repair. The follow-up information was based on physical examination by veterinarian. The owner reported that there was no evidence of complications related to surgery.

Three dogs presented to the Veterinary Medical Teaching Hospital of the University of Konkuk and Hangang Animal Hospital with a history of perineal swelling. No tenesmus, stranguria, or any clinical signs other than the swelling was observed by the owners in three dogs. On physical examination, the swelling was observed unilaterally in two dogs and bilaterally in a dog. Digital palpation to the swelling confirmed reducible perineal herniation in two dogs and irreducible perineal herniation in a dog. Plain radiographs revealed that no pelvic or abdominal contents other than the fat were displaced into subcutaneous perineal region in three dogs. Internal obturator transposition herniorrhaphy was performed for correction of perineal herniation in three dogs. Contralateral herniation involving fat was noted after surgery in a dog. The follow-up information was based on physical examination by veterinarians or telephone interview with owners. The owners reported that there was no evidence of complications related to surgery such as sciatic nerve injury, rectal prolapse, wound dehiscence, or perineal hernia recurrence in all dogs.

Perineal hernia occurs spontaneously in older male dogs after idiopathic weakening of the pelvic diaphragm A 14-year-old uncastrated male shih tzu dog with right-sided perineal swelling was referred to the Veterinary Medical Teaching Hospital of Konkuk University. He had sign of perineal swelling for three years. Plain radiography documented the extent of rectal and colonic dilation in the herinal sac. During surgery, external anal sphincter muscle, coccygeus muscle and levator am muscle were weakened due to the three years of herniation. Internal obturator muscle transposition method was not enough for large defect, so mesh was applied to reduce the hernial sac. Internal obturator muscle transposition combined with using of polypropylene mesh was successfully performed in this dog.
