266 DISEASES OF THE PENIS AND PREPUCE 



(c) Sequel to specific infectious diseases, as distemper. 



(d) Follows in some cases of mange and eczema. 



In all of the above causes we find that the condition is 

 brought about by infection either as a primary cause, or due 

 to reduced resistance of the tissues by other diseases which 

 allows secondary infection to take place. In some, accumu- 

 lations of dirt will favor injury to the mucosa with subsequent 

 infection. 



Symptoms.— The mucosa of the prepuce will be injected, 

 swollen, and there is present at the preputial opening a dis- 

 charge of pus of a yellowish or greenish color. Some of the 

 material accumulates around the preputial opening aggluti- 

 nating the hair, drying and forming crusts. Examination 

 of the mucosa shows a marked catarrhal inflammation. 



Prognosis.— The condition is not serious as in most cases it 

 remains local. When treatment is applied, recovery takes 

 place after a few weeks. 



Treatment.— The parts are thoroughly cleansed and all 

 long hairs removed with the scissors. The prepuce should 

 be washed thoroughly once or twice daily with antiseptic 

 and astringent solutions (alum, 2 per cent.; silver nitrate, 

 i per cent.; zinc sulphate, 1 per cent.). 



PHIMOSIS. 



Definition.— A contraction of the prepuce in front of the 

 glans penis, preventing the projection of the penis, interfering 

 with coition, and in some cases the escape of urine. 



Etiology.— Phimosis is a congenital defect in puppies. It 

 may cause in some cases almost complete occlusion. It 

 results frequently from trauma of various kinds, the subse- 

 quent cicatricial tissue formed leading to constriction. Acute 

 infectious inflammation (balanitis) with severe swelling will 

 produce a temporary closure, and in some cases, owing to 

 the change in the structure of the tissues, a permanent 

 contraction. 



Symptoms.— In puppies it will be noticed that urine cannot 

 be discharged; there may be frequent attempts at micturition, 

 with only a small quantity passed or there may be complete
