🔍 What Is a Vaginal Protrusion?

A vaginal protrusion in a dog or cat appears as a fleshy, pink mass extending from the vaginal area. While alarming, most cases are benign and treatable—especially in unspayed pets. These protrusions are rarely seen in spayed animals. They may be caused by hyperplasia, prolapse, swelling, or a mass. 🧬

🧠 Understanding the Types

🔸 Vaginal Hyperplasia

• 📈 Overgrowth of vaginal tissue due to estrogen
• 🩸 Occurs during proestrus or estrus (heat)
• 👀 Appears smooth, shiny, and may become cracked
• 🧬 More common in breeds like Boxers, Labs, Bulldogs, German Shepherds

🔸 Vaginal Prolapse

• 🔄 Vaginal wall everts outward—like turning a sock inside out
• 🛑 Can block urination or become necrotic if untreated
• ⚠️ Can occur during heat or delivery

🔸 Vaginal Mass

• 🧫 Could be a polyp, leiomyoma, leiomyosarcoma, or TVT
• 📍 Typically seen in older, intact females
• 🔬 Requires biopsy to diagnose properly

🚨 When It’s an Emergency

• 🩸 Bleeding or foul-smelling discharge
• 🚽 Difficulty urinating
• 🤕 Tissue appears dried, cracked, or darkened (indicating necrosis)
• 🐶 Active labor and visible tissue abnormality

🩺 Diagnosing the Cause

• 👁️ Visual exam of the vaginal area
• 📈 Assessment of heat cycle timing
• 🧪 Urinalysis, bloodwork, and cultures if infection is suspected
• 🔬 Biopsy for masses or unknown tissue types
• 📸 Imaging (radiographs or ultrasound) may be needed

💊 Treatment for Vaginal Prolapse & Hyperplasia

Conservative Management (Mild Cases)

🔬 Treatment for Vaginal Masses
