For pet owners, the sight of masses protruding from their dog's or cat's vagina can spark concern. Thankfully, such occurrences are infrequent and are rarely observed in spayed pets.
Deciphering the Terminology: Hyperplasia, Swelling, Prolapse, or Mass?
These terms might seem confusing, but understanding them is crucial. Vaginal hyperplasia, swelling, and prolapse might appear similar but have distinct characteristics. Hyperplasia refers to excessive tissue growth due to an increase in cell count. This differs from swelling, which results from fluid accumulation between cells. Prolapse is the eversion (turning inside out) of the vagina, often accompanied by swelling. Visualize it like a sock being turned inside out. Vaginal hyperplasia is more uniform compared to a mass. Imagine a thick wool sock compared to a thin cotton one—the "walls" of the wool sock (vagina) are thicker. If this sock can't stretch outward due to tight shoes, it might feel constrictive.
When vaginal hyperplasia leads to prolapse, a round, tongue- or doughnut-shaped mass becomes evident, sometimes hard to miss as the pet focuses on that area. This prolapse initially appears smooth and shiny, later developing fissures as it dries out. It's an exaggerated response to estrogen and typically emerges just before or during a pet's heat cycle. It primarily occurs in intact dogs and cats due to estrogen levels. However, if a spayed pet encounters external estrogen exposure, such as licking estrogen cream from its owner, prolapse could occur. Prolapse might also result from labor and delivery stress or hormonal fluctuations before giving birth.
During whelping, any unusual vaginal protrusion demands immediate medical attention.
Hyperplasia can hinder breeding by causing discomfort; preliminary signs could be a reluctance to mate or difficulties urinating. Sometimes, discomfort extends through pregnancy or recurs postpartum.
Breeds predisposed to vaginal hyperplasia include the boxer, English bulldog, mastiff, German shepherd dog, Saint Bernard, Labrador retriever, Chesapeake Bay retriever, Airedale terrier, English springer spaniel, American pit bull terrier, and Weimaraner. While genetics and heritability aren't fully understood, it's advisable not to breed dogs with a history of prolapse.
Distinguishing a Mass
Masses form from cell collections. Occasionally, masses develop within a dog's (or rarely, a cat's) vagina, growing until they protrude. Vaginal masses, benign or malignant, are rare, especially in spayed pets. Picture a burr inside your sock—similarly, vaginal masses protrude. Pedunculated masses, attached to a stalk, are often vaginal polyps, more common in intact bitches. Sessile masses, which aren't on a stalk, might be leiomyomas or leiomyosarcomas, differentiated via biopsy. Other neoplasms can also arise.
Transmissible venereal tumors can induce vaginal protrusions in dogs.
Managing Vaginal Prolapses
- Vaginal prolapses often resolve as the heat cycle progresses or after spaying unless extreme. Mild cases require cleaning and ointment for moisture retention.
- If tissue damage is minimal, a veterinarian can manually push it back, aided by appropriate cleaning and reducing swelling with hypertonic dextrose or sugar. Sutures might secure it.
- Necrotic tissue necessitates surgical removal. Spaying prevents recurrence and can be done concurrently.
- Dogs facing delivery difficulties due to prolapse might need a C-section.
- Supportive care, including an E-collar, diaper with lubricated pad, and hormone treatment, can expedite ovulation. However, hormone response is limited in dogs.
- Post-treatment, monitor intact dogs for relapse.
Managing Vaginal Masses
Mass treatment depends on factors like type (benign or cancerous), location, extent, and metastasis. Consult your vet to discuss options for a vaginal mass.
To sum up, if you spot a pink mass protruding from your pet's vagina, inform your vet. If your pet displays discomfort or urination issues, contact your veterinarian or an emergency clinic promptly. Vigilance and timely action ensure your pet's well-being.
