🔍 What Are Paraphimosis and Phimosis?

Paraphimosis is the inability of a dog or cat to retract the penis back into the prepuce (sheath). In contrast, phimosis is the inability to extend the penis from the sheath. Though less common, both conditions can lead to serious complications if not treated promptly. 🧠

⚠️ Paraphimosis: When the Penis Won’t Retract

This condition occurs when the penis remains exposed for more than two hours. It may begin after sexual excitement, masturbation, trauma, or grooming issues, and often leads to swelling, dryness, and potential tissue damage.

Common Causes:

• 🧬 Congenital narrow prepuce
• 🧵 Hair entanglement or matting at the base of the penis
• 💢 Trauma or infection
• 🦠 Foreign objects in the sheath
• 🦴 Os penis (penile bone) fractures
• 🧫 Cancer or tumors
• 🛠️ Post-surgical complications

Emergency Signs:

• 🔴 Red, dry, or discolored penis
• 🤕 Pain, excessive licking, or urine dribbling
• 💉 Swelling or inability to urinate

🛠️ Paraphimosis Treatment

• 🧴 Lubrication and gentle retraction
• ✂️ Trim entangled hair at the base
• 🧊 Sugar wraps or cold compresses to reduce swelling
• 💉 Sedation or general anesthesia may be needed
• 🧫 Antibiotics for infection
• 🔄 Debridement or, in severe cases, penile amputation may be required
• 🧪 Urinalysis, biopsy, or culture may help rule out complications

💡 Prevention includes keeping the area clean, trimming long hair, and avoiding overexposure during mating or collection.

🧬 Phimosis: When the Penis Won’t Extend

Phimosis occurs when the sheath opening is too small, preventing the penis from exiting. This can be congenital (present from birth) or acquired due to inflammation, trauma, or tumors. Though rare, it can interfere with urination and mating. 🚫

Signs of Phimosis:

• 🚽 Urine pooling or dribbling from the sheath
• 🩸 Bloody discharge
• 👅 Excessive licking of the sheath
• 🐶 Inability to breed or abnormal mating behavior

Treatment:

• 🔍 Visual inspection and diagnostics (biopsy if needed)
• 🔧 Surgical widening of the sheath under general anesthesia
• 💊 Addressing any underlying infection or inflammation

🐶 Final Thoughts from Dr Duncan Houston

Paraphimosis and phimosis may be uncommon, but they are serious. With timely care, most dogs recover fully—but delays can lead to irreversible damage. Don’t hesitate to call your vet or seek immediate support. 💙
