liLENNORRHCEA IN THE DOG. 55 



portion of the urethra is affected, examination of the urine voided 

 towards the end of the act of micturition enables the disease to be 

 distinguished from affections of the genito-urinary organs proper. 

 Polypi developed on the penis, or lining membrane of the prepuce, 

 give rise to a sanguinolent discharge, and as a rule produce knobby 

 swellings of the sheath. Even when of small size, or deeply situated, 

 they can immediately be diagnosed by exposing the base of the penis 

 and drawing back the sheath. I should remind you of the occurrence 

 of traumatic blennorrhoea, caused by the accidental entry into the 

 sheath of some foreign body like a fragment of straws a thorn, a husk of 

 grain, a little fragment of wood, or more rarely by a ligature, which 

 some mischievous person or child has applied to the penis. 



Local applications are used in all cases, but in some varieties of the 

 disease constitutional treatment appropriate to the general condition of 

 the patient is also necessary. 



The sheath is cleansed and disinfected by syringing out, for some 

 days in succession, with warm boric solution. This is retained by 

 closing the preputial orifice with the finger, and any fragments of mucus 

 adherent to the lining membrane are removed by gently massaging the 

 parts for a few moments before the liquid is allowed to escape. Boric 

 acid is afterwards replaced by a 'i or '05 per cent, sublimate, by i per 

 cent, sulphate or chloride of zinc, or by 2 to 3 per cent, alum or tannin 

 solution. Injections need only be made once a day, or even once every 

 two days. If the discharge diminishes rapidly the injections should 

 still be continued for a time, as when it disappears too soon it is apt 

 to return ; a drop of muco-pus is seen one morning at the opening of 

 the sheath, and each succeeding day increases. The i or 2 per cent, 

 solution of nitrate of silver is rarely necessary, even in old-standing 

 cases, the i per cent, solution of sublimate or chloride of zinc being 

 preferable. 



In the acute form of blennorrhoea the same treatment with boric or 

 sublimate injections is indicated. In addition, a moist antiseptic com- 

 press is applied to the sheath, and retained in position with a bandage. 



For distemper or other complications young dogs often require in- 

 ternal medication. According to their age, temperament, and bodily 

 condition, adults are treated with alkalies, arsenical preparations, iodide 

 of potassium, or iodide of iron.
