Occurrence of vaginal hyperplasia among intact dogs*

Abstract

Hyperplasia of vaginal mucous membrane is an unusual reproductive disorder observed in canines. It is the protrusion of oedematous vaginal tissue into and through the opening of the vulva occurring during proestrus and oestrus stages of the sexual cycle. This study was aimed to find out the overall occurrence of canine vaginal hyperplasia and its occurrence based on breeds, age, parity and stage of oestrous cycle. The occurrence of canine vaginal hyperplasia was 1.02 per cent. The highest occurrence of vaginal hyperplasia within a breed was observed in Labrador retrievers (48.94%), while the lowest occurrence was in German shepherd, Spitz, and Dachshund breeds (2.13%). The highest occurrence was recorded in dogs of one to two years old (43.62%) and the lowest occurrence in dogs of above 4 years of age (13.83%). Highest occurrence of vaginal hyperplasia was found in nulliparous (60.71%) and in intact dogs (100%).
