130 The Management and Diseases of the Dog. 
If the animal is plethoric a dose of aperient medicine is 
advisable. Ifanamic, tonics should be given, and a liberal 
but unstimulating diet allowed. 
Occasionally the same condition exists in bitches, and 
may be removed by the same measures. 
WARTS ON THE PENIS. 
These are not unfrequent in the dog. They may be the 
result of the former complaint, or exist independently. 
There may be only asingle growth, or several isolated, or 
they may be clustered together. 
Treatment.—The seat of the affection having been ex- 
posed, the excrescences may be removed by excision or 
ligature, after which the parts should be slightly pencilled 
with lunar caustic. When there is an excessive congrega- 
tion of warts, and a large amount of mucous membrane is 
involved, the repeated application of caustic or acetic acid 
will be the safest remedy. Occasionally warty adhesion 
exists between the sheath and the penis, which is of serious 
importance in stud dogs. In such a case a competent 
canine veterinary surgeon should be consulted, the necessary 
operation being too delicate for an amateur to attempt. 
SCROTAL IRRITATION. 
Dogs, especially aged ones, and those which have been 
freely used for stud purposes, are frequently troubled with 
irritation of the scrotum, which has been described by some 
authors (in my opinion, wrongly) as cancer. 
Causes.—The irritation is due to a plethoric condition of 
the scrotum. The circulation of blood in the integument 
being excessive, an amount of congestion takes place, 
resulting in the irritation named, which Nature endeavours 
to relieve by a serous exudation in the form of pimples. 
Symptoms.—The first indications are those usually found in 
all inflammatory processes—heat, redness, swelling, and sore- 
ness. Inthecourse of afew days minute pimples appear; these
