212 DISEASES OF THE URINARY AND SEXUAL APPARATUS 



are having their first littoi-s. In the acute form the Labia pudendi are 

 tumefied and painful to the touch. The condition is indicated by a 

 whitish, purulent discharge, in some cases being foetid, which is generally 

 licked off by the animal. The examination in the larger animals can be 

 made by means of a speculum (Fig. 85) . On examination of the vagina 

 we find it intensely red and inflamed and covered with a gray- 

 ish, mucous discharge; the mucus is also grayish in color, and 

 has in some cases striated lines or petechial patches. In 

 chronic cases there is a constant discharge from the vulva of 

 a whitish-yellow muco-purulent fluid which agglutinates the 

 hair in that region, and the animal is constantly licking the 

 discharge; the mucus is sometimes grayish in color, and car- 

 cinoma is often present. (8ce chapter on Tumors for further 

 details.) 



The therapeutic treatment consists of daily injections and 

 irrigations of astringent or disinfectant washes of sulphate of 

 zinc (1 per cent.), or permanganate of potassium solution, 

 boric acid, or creolin, lysol, bacillol, etc., or a solution of acacia (mucil- 

 age) is useful. In chronic cases use nitrate of silver, 1 per cent, solu- 

 tion, or sulphate of zinc, 2 to 100 solution. 



Prolapse of the Vagina and Uterus. 



{Prolapsus Vagince; Prolapsus Uteri.) 



Prolapse of the vagina is more common than prolapse of the uterus; 

 it is seen especially in young bitches, frequently at the termination of heat 

 and occasionally at the latter period of pregnancy; it rarely occurs as a 

 result of parturition. In some instances it is accompanied by serious 

 alterations of the vagina, especially hypertrophic alterations, and also in 

 rare cases we find polypus formations. As a rule there is more or less 

 protrusion of the vagina through the vulva, appearing in the form of pear- 

 or flap-shaped, red, inflamed tissue covered with mucus (Fig. 86). In 

 very rare instances the prolapse is so great that the os of the vagina can 

 be seen through the external opening. When the vagina has been parti- 

 ally prolapsed for some time, the exposed portion becomes so infiltrated 

 and hypertrophied that it becomes impossible to reduce it. Care must 

 be taken to differentiate between a pedunculated fil^roma and the pro- 

 lapsed vagina, and instances are not rare where the vagina is prolapsed 

 and a tumor whose existence is never suspected also accompanies it. 



The prolapse of the uterus in the dog is practically impossible, for the 

 reason that the uterus itself is merely a body in name, and really the uterus
