250 THEORY AND PRACTICE 



PHIMOSIS. 



Phimosis is the inabiHty of the animal to extend the penis. 

 This may be due to congenital malformation. It may be due to 

 ulcer or to some other interference, as edema of the sheath. 



This condition can be recognized by the foulness of the 

 sheath in which the animal urinates. 



Treatment. — In congenital cases cast the animal if necessary 

 and insert a probe-pointed bistoury and cut down the prepuse 

 about half an inch to one inch. Bring the organ down and wash 

 off the parts. The sheath should be cleaned out night and 

 miOrning until the wound has begun to granulate. Then use the 

 white solution. 



Horses may get the notion that they cannot let the penis 

 down and consequently urinate in the sheath. Put a twitch on 

 the animal and bring the penis down once a day for three or 

 four days. 



PARAPHIMOSIS. 



Paraphimosis is the inability on the part of an animal to re- 

 tract the penis. There may be a swelling of the sheath and the 

 penis itself may be swollen. Following castration we find a typi- 

 cal example of this disease, probably on account of the swelling 

 of the penis and sheath. The penis swells mostly on the dorsal 

 side and the covering becomes tense and glistening. Such a 

 severe case is usually due to local irritation. Paralysis of the 

 penis may be the cause. In the dog sometimes following copula- 

 tion the erection cannot subside and the organ becomes gangren- 

 ous in the course of three or four days. 



Treatment. — If the condition comes from castration, you will 

 have to reduce the swelling. Give diuretics internally and plenty 

 of exercise and fresh water. If it comes from injury and in- 

 flammation has set in, put on ice pack tight upon the horse's 

 body near the penis. Keep this up until the swelling goes down. 

 Give diuretics and laxatives. Sometimes we find that the penis 

 is cold and cyanotic; scarify it from six to a dozen cuts and 

 foment it with tepid water. This will produce a dilation of the
