158 KENNEL DISEASES. 
ference, but, when it is absolutely necessary, an injection of sulphate of zinc— 
two grains, to water one ounce — may be used two or three times daily. If 
under this treatment recovery does not occur in the course of a week or ten 
days, there should be substituted an injection made of one drachm of the sub- 
nitrate of bismuth, two and one-half ounces of water, and two drachms of 
glycerin, to be used two or three times daily. If this in turn fails, capsules of 
the balsam copaiba and cubebs should be obtained, and one administered, con- 
cealed in a bit of meat, three or four times daily. 
Such capsules are on sale with druggists, and are appropriate for all breeds 
excepting the smallest, with which it is best to trust wholly to the local measures 
of treatment advised. 
In all cases of urethritis the diet should consist of bland foods, and milk may 
wisely be the main reliance. 
GENITAL AFFECTIONS. 
In consequence of a small number of causes the genitals of males may suffer 
from inflammation. Those causes are nearly all traumatic, and consist of blows, 
kicks, or other direct injuries; but in very rare instances quite serious trouble is 
induced by a parasite known as the “bot-fly.” 
This parasite or grub burrows into the walls of the bag, called the scrotum, 
which encloses the glandular organs, and causes swelling in the immediate 
neighborhood until a round, quite hard mass or “lump” is formed. 
This enlargement may exist for a long time without change, apparently caus- 
ing the dog but little if any discomfort; but it is liable in time to become an 
abscess, which, if allowed to run the usual course would likely excite much 
inflammation in adjacent parts, also destruction of the affected walls, and pos- 
sibly the gland within. 
Inflammations induced by injuries require much the same treatment as simi- 
lar troubles in other localities; that is, if there is much swelling and tenderness, 
soothing applications are demanded, and may be of warm water merely; or if 
the skin is not broken, the following can be advantageously employed: Solution 
of subacetate of lead, one ounce; dilute acetic acid, half an ounce; water, one 
pint. 
With this the parts should be frequently bathed, and kept as quiet as possible. 
Were the glandular organs seriously injured and the chances of a complete 
cure decidedly doubtful, castration might properly be performed. 
To remove a bot-fly, an incision should be carefully made and the grub dis- 
sected out, entire if possible ; but if there is doubt as to the removal being com- 
plete, the bottom of the incision should be thoroughly cauterized, that any 
remaining portions of the parasite may be with certainty destroyed.
