332 HERNIA. 



cases we observe a prolapse of the duodenum or lower bowel, and 

 sometimes in the dog we observe a prolapse of the bladder. 



In the dog we recognize perineal hernia by a soft swelling the 

 size of an egg or the size of a hand. This appears in the side and 

 above the anus, between the root of the tail and the tuber ischii. 

 In the bitch this hernial swelling is seen under the vulva and on 

 the peritoneum. This hernia can only be removed by means of 

 an operation.
