282 THE DOG IN DISEASE. 



pain and irritation. Inflammation may extend to the cov- 

 ering of the testicles {scrotum), or this may arise inde- 

 pendently in old dogs, and requires attention lest the 

 parts become the seat of malignant disease, as cancer or 

 sarcoma. Balanitis in chronic form is common. 



Treatment. — The indication in all these cases is to re- 

 lieve irritation, both from the actual inflammation and 

 from the discharges. The sheath should be kept clean 

 by frequent washing with warm water or injecting up 

 into it from a syringe the same, and, if this does not 

 answer of itself, astringent and soothing solutions, such 

 as tannic acid, sulphate of zinc, acetate of lead, etc., 

 which are all the more effective if some glycerin be 

 added. 



A very good plan is to insert a little surgeon's lint or 

 some cotton-wool dipped in the astringent solution within 

 the sheath for twenty minutes. The addition of laudanum 

 or morphia to the cleansing water or to the astringent 

 lotion will be helpful. 



In the case of urethritis, it will be necessary to inject 

 one of these solutions after the use of very warm water 

 into the urethra. 



Such combinations as the following will illustrate how 

 useful lotions may be made :
