Vaginal Hyperplasia ------------------- General Information During each breeding season (heat) in female dogs, the lining of the vagina becomes congested and swollen. This change results from the high levels of estrogen produced by the ovaries during this time. In some females, this swelling becomes highly exaggerated and vaginal tissue protrudes from the vaginal opening as a pinkish, fleshy mass. While some dogs recover spontaneously, others must be treated to prevent injury to the exposed vaginal tissue. Vaginal hyperplasia occurs most commonly in young females, especially during the first heat period. It commonly recurs with each heat period. Surgical removal of the ovaries and uterus (spaying) is the only permanent cure. Important Points in Treatment 1. Treatment is designed to reduce vaginal swelling and protect the vaginal tissue. In severe cases, the vaginal tissue must be surgically removed. 2. Spaying is desirable to prevent recurrence. 3. Give all medication. Call the doctor if you cannot give the medication. 4.

Instructions for surgical patients: Notify the Doctor if Any of the Following Occur: * Your dog irritates or damages the exposed tissues. * There is bleeding from the enlarged tissues. * There is bleeding from the surgical site. * Your dog's condition worsens.
