Diseases of the Urinary System. 209 



the glans penis is swollen, extruded, and mostly erect, a 

 imall quantity of pustular fluid oozing from the opening. 

 Pain is evident in urination, and the animal constantly 

 licks the exposed member. In other forms of the dis- 

 ease the prepuce is swollen and covers the glans penis, 

 retaining the discharge to the further detriment of the 

 organ, but allowing a portion to escape and accumulate 

 in drying on the hairs around the orifice. By external 

 pressure, which the animal stoutly resists, a large quantity 

 of discharge may be obtained, sometimes having a dis- 

 agreeable odour; and not uncommonly the diseased 

 parts are invaded by abscesses and sinuses to a serious 

 extent. 



Treatment. — After a thorough cleansing, the long hairs 

 should be removed to avoid the accumulation of dis- 

 charge and dirt, the dog should be immersed in a warm 

 bath, or fomentations may be locally applied. In either 

 case care must be exercised in order to dry the patient 

 and prevent his taking cold. Astringent lotions are then 

 needed, or the " Sanitas " mixtures {see Antiseptics) will 

 be highly beneficial. The bowels should be moved by 

 the castor-oil mixture, and tonics, combined with muci- 

 laginous fluids, are essential. 



Parasitic Invasion of the Urethra is on record. 

 In an instance falling beneath the notice of M. Seon, the 

 worm was believed to be the male Eustrongylus glgas^ 

 upwards of four inches long, and was detected during an 

 attack of urethral irritation and paroxysmal retention of 

 urine, occupying the entire length of the urethra. Removal 

 of the parasite aflbrded instant relief.
