 is generally licked off by the animal. The examina- 

 tion can be made by means of a speculum in the larger 

 animals (Fig. 53). On examination of the vagina we 

 find it intensely red and inflamed and covered with 

 a grayish, mucous discharge; the mucus is also grayish 

 in color; carcinoma is often present. (See chapter on 

 Tumors for further details.)

Prolapsus of the Vagina and Uterus. 

 {Prolapsus Vaginae; Prolapsus Uteri.) 



Prolapsus of the vagina is more common than prolapsus of the 

 uterus. In some instances it is accompanied by serious alterations 

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

 rare cases, polypus formations. These alterations are generally 

 •caused by difficult whelping. As a rule, there is more or less pro- 

 trusion of the vagina through the vulva, appearing in the form of 

 pear- or flap-shaped, red, inflamed tissue covered with mucus. In 

 very rare instances the prolapsus is so great that the os of the 

 vagina can be seen through the external opening. When the 

 uterus is prolapsed the protruded portion is forced out of the 

 vulva, and we see a pear-shaped body, intensely red, with salient 

 borders. One horn of the uterus is protruded only; the author 

 has never heard of a case where both horns were protruded. 



The prolapse of the uterus in the dog is practically impossi- 

 ble, for the reason that the uterus itself is merely a body in name, 

 and really the uterus consists in the horns, the true body of the 

 uterus being a small body from which the horns bifurcate almost 

 at the OS. (Fig. 54. ) 



The therapeutics of prolapsus of the vagina is practically that 

 used in prolapsus of the anus and rectum. The retention of the 

 vagina is much more difficult than returning it to its normal 

 position. Hertwig advises that the vagina be returned, and for 

 several hours it is held in position by the fingers, and if that is
