406 The Diseases of Animals 
PARALYSIS OF THE PENIS 
This condition most frequently oceurs in aged horses 
and is due to debility of advancing age. It may also 
occur in serving stallions from injury or debility. In 
old horses the only treatment is to amputate the penis. 
In other cases, the cause should be sought and removed; 
this to be followed by a course of tonic medicines and 
nutritious food. Give Fowler’s solution (of arsenic), 
beginning with one-dram doses in the feed once daily 
and increasing one dram daily until half an ounce is 
given in the feed three times a day. One dram of 
pulverized nux vomica seed in the feed three times 
a day is good. 
FREQUENT URINATING IN MARES 
Some mares have a most disagreeable habit of pass- 
ing small quantities of urine and often switching the 
tail at the same time. Such mares are usually of a 
nervous temperament; and the vice is most likely to 
occur when the animal is irritated or in heat. 
In some cases, when the animal is not badly affected, 
allowing her to raise a colt will cause the difficulty to 
disappear, although it is difficult, as a rule, to get 
such mares to breed. In other instances, the removal 
of the “clitoris,” a small organ just inside the lower 
part of the vulva, will stop the trouble. In bad eases, 
the best treatment is to spay the mare. Usually this 
will stop the vice, but sometimes it will not.
