 sheath, etc. 



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

 man beings, tlie 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

 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
