Vulvitis and Vaginitis in Horses

Vulvitis (inflammation of the vulva) and vaginitis (inflammation of the vagina) can develop due to difficult labor, chronic contamination of the reproductive tract due to poor conformation, sexually transmitted diseases, or mating. Bruises and hematomas (a pool of blood under the surface of the skin) of the vagina may be found in mares following delivery of a foal. Severe inflammation of the vulva and vagina, including local tissue death, may also occur. The signs of severe inflammation can include an arched back, elevated tail, poor appetite, straining, swelling of the vulva, and a foul-smelling, watery discharge.
