DISEASES OF THE GENITAL ORGANS. 281

 sheath, etc. 



Some writers claim that the dog may have, like hu- 

 man beings, the specific inflammation known as gonor- 

 rhoea from sexual intercourse, and even syphilis. The 

 subject is worthy of further investigation. 



The symptoms of urethritis are uneasiness, possibly 

 painful micturition, licking the penis, and especially a 

 muco-purulent whitish or yellowish discharge, which can 

 be traced within the penis i. e., to the urethra. 



Balanitis is an inflammation of the sheath (prepuce) 

 covering the penis. The symptoms are as in the preced-

 this disease, though the two may be associated, as they 

 not infrequently are. 



The sheath is swollen, tender, and soon gives rise to a 

 muco-purulent discharge. The dog is disgustingly atten- 

 tive to his genitals when they are affected. 



If not relieved, the prepuce may become swollen to 

 such a degree as to prevent the extrusion of the penis, 

 (phimosis) and may even in some degree interfere with 

 the passage of urine. 



Occasionally, from long-continued sexual excitement, 

 etc., the prepuce prevents the return of the penis within 

 the sheath (paraphimosis), and the former becomes greatly 

 swollen, and, in its exposed condition, liable to abrasions 

 and ulcerations. The latter are apt to occur from pent-up 

 discharges, as in balanitis, so that the whole may become 

 very offensive to the associates of the dog, and a source of 

 worry and humiliation to himself. The animal always 

 licks the parts, his own method of cleansing and relieving
