Two Cases of Canine Pyovagina
Author information

1989 Volume 42 Issue 3 Pages 185-188


Two cases of pyovagina were admitted to the veterinary teaching hospital of the Osaka Prefecture University with the chief complaint of a persistent draining of pus from the vulva.
One of these was a primipara Yorkshire Terrier dog which was six years old, and the other was a mongrel bitch, both of whose medical histories were unknown.
Although their uteri and ovaries were normal, they had a dilation of the vagina and retention of pus in it. Various bacteria, such as Streptococcus and Staphylococcus, were detected in the pus.
The etiology of the disease was not unknown in the first case where no stenosis or closure in the vagina could be found, but it had a history of labor and also abortion had been reported by another researcher in an other case. From this information, insufficient involution of the vagina after labor or abortion, may probably have been the causative factor. In our second case, the cause of vaginal dilatation and retention of pus was an inserted foreign body in the lumen of the vagina by a sexual pervert.
