Does Your Dog Have Urethral Prolapse?
A red bump, bleeding, and constant licking. Here's what urethral prolapse looks like in dogs and what to do.
If you’ve noticed a small red or purplish bump at the tip of your dog’s penis, maybe with a little blood or constant licking, take a breath. What you’re likely looking at is urethral prolapse, and while it looks alarming, it’s a treatable condition. It happens when the inner lining of the urethra slips forward and protrudes through the tip of the penis, forming a small fleshy ring, and it’s most common in young, intact male dogs, particularly English Bulldogs and other flat-faced breeds.
TL;DR
- Urethral prolapse looks like a red or purple doughnut-shaped bump at the tip of your dog’s penis, and it can bleed, especially during excitement or arousal.
- Young, intact male English Bulldogs and other brachycephalic breeds are most at risk, and sexual arousal or straining to urinate are common triggers.
- Treatment usually involves surgery (either reattaching or removing the prolapsed tissue), often paired with neutering to reduce the chance of it happening again.
- While you wait for a vet appointment, you can take steps at home to protect the area and reduce bleeding.
- Surgical correction isn’t cheap, and recurrence is possible, so having pet insurance in place before a diagnosis matters.
What does urethral prolapse looks like in dogs?
The symptom that sends most pet parents to Google is a visible red bump at the very tip of the penis. It’s easy to mistake for an injury or a growth, but it’s actually tissue that belongs inside the body that has pushed its way out. Here’s what to look for:
- A small, round, red or dark pink bump at the tip of the penis, often described as looking like a tiny doughnut or rosette
- Bleeding from the penis, which may appear on bedding, the floor, or after your dog licks the area
- Blood in the urine (called hematuria), which can look pink or red in the urine stream
- Excessive licking at the penis or genital area
- Straining or discomfort when urinating
- Increased bleeding or swelling during or after sexual arousal or excitement
The bleeding tends to be worse when your dog gets excited. Because the exposed tissue is delicate and unprotected, even normal arousal can trigger a flare-up. It’s not life-threatening in the short term, but it does need veterinary attention.
Why does a urethral prolapse happen?
There isn’t always one single cause, but there are clear risk factors that make some dogs much more likely to develop this condition.
Breed and anatomy
English Bulldogs and other brachycephalic breeds (flat-faced dogs like French Bulldogs and Boston Terriers) are significantly overrepresented in urethral prolapse cases. Vets believe that anatomical differences in these breeds, combined with the physical strain that comes with their compressed airways, may contribute to increased abdominal pressure that pushes tissue outward over time.
Being intact and sexually aroused
Intact male dogs (dogs that haven’t been neutered) are far more prone to this condition. Sexual arousal increases blood flow and pressure in the genital area, which can cause the urethral lining to push through or worsen an existing prolapse. This is a key reason vets almost always recommend neutering as part of the treatment plan.
Straining and genitourinary issues
Straining to urinate, such as from a urinary tract infection, bladder stones, or other blockages, increases pressure in the area and can trigger or worsen a prolapse. Any underlying issue that makes urination difficult should be identified and treated alongside the prolapse itself.
Diagnosis and treatment options
A vet can usually diagnose urethral prolapse just by looking at the tip of the penis. That said, they’ll also want to rule out any underlying causes, so expect a physical exam, a urine test to check for infection or blood, and possibly imaging to look for bladder stones or other issues.
For treatment, there are two main surgical approaches your vet may recommend:
- Urethropexy: the prolapsed tissue is stitched back into its normal position inside the penis. This approach preserves the tissue and works well if it hasn’t been severely damaged.
- Urethral resection: the prolapsed portion of tissue is surgically removed, and the edges are sutured closed. This is typically recommended when the tissue is too damaged or swollen to be repositioned.
In most cases, neutering is performed at the same time or strongly recommended alongside surgery. Removing the hormonal drive that causes arousal significantly reduces the risk of the prolapse coming back.
If an underlying cause like a urinary tract infection or bladder stones is found, that gets treated too, since unresolved straining can undo surgical repair.
How do you prevent recurrence and care for your dog at home?
The prolapse can come back, especially if the root causes aren’t addressed. Here’s what to know about reducing that risk and protecting your dog in the meantime.
Why neutering matters
Sexual arousal is one of the biggest drivers of urethral prolapse in intact dogs. After neutering, testosterone levels drop significantly, reducing the frequency and intensity of arousal-related engorgement. Most vets consider neutering essential, not optional, for dogs who’ve had a urethral prolapse. It’s often performed at the same time as the surgical repair.
Managing straining long-term
If your dog has any ongoing urinary issues, staying on top of them matters. Keep up with follow-up vet visits, feed a diet appropriate for urinary health if recommended, and make sure your dog has regular access to water and bathroom breaks to avoid unnecessary straining.
At-home care while you wait for surgery
If surgery is a few days out, here’s how to protect the area in the meantime:
| What to do | Why it matters |
|---|---|
| Gently clean the area with a damp cloth and keep it moist with a sterile lubricant or water-based gel | Prevents the exposed tissue from drying out and cracking |
| Use a cone (e-collar) | Stops licking, which introduces bacteria and irritates the tissue |
| Limit excitement and stimulation, including play and interactions with other dogs | Arousal worsens the prolapse and increases bleeding |
| Use washable covers on bedding and furniture | Manages any bleeding until surgery |
| Call your vet if bleeding becomes heavy, the tissue turns dark purple or black, or your dog can’t urinate | These are signs of an emergency |
Does pet insurance cover urethral prolapse?
Yes, urethral prolapse is eligible for coverage under a Lemonade Pet accident and illness policy, when the condition isn’t pre-existing. That means your dog shouldn’t be showing any signs or symptoms before your policy starts or during your waiting period.
Surgery, pre-op testing, anesthesia, hospitalization, follow-up care, and neutering add up quickly. And if recurrence happens and a second procedure is needed, those costs stack. For Bulldogs and other brachycephalic breeds, enrolling while your dog is young and healthy is what keeps those costs eligible for coverage when you need it.
Before we go
A red bump at the tip of your dog’s penis is alarming to see, but urethral prolapse is something vets know how to treat. Get him seen soon, keep him calm and the area clean in the meantime, and don’t skip the conversation about neutering. The sooner it’s addressed, the better the outcome and the lower the risk of it coming back.
Frequently Asked Questions
Is urethral prolapse in dogs an emergency?
It’s not always a same-day emergency, but it does need prompt veterinary attention. Call your vet right away if the bleeding is heavy, your dog can’t urinate, or the tissue looks dark purple or black, as those signs suggest the tissue may be losing blood supply.
Can a prolapsed urethra in a dog heal on its own?
No. Urethral prolapse doesn’t resolve without treatment. The tissue will remain exposed and vulnerable to injury, infection, and worsening, so surgical correction is almost always necessary.
Why is my English Bulldog more prone to urethral prolapse?
English Bulldogs and other brachycephalic breeds have anatomical traits that may increase abdominal pressure, and as intact males, hormonal arousal adds additional risk. This combination makes Bulldogs one of the most commonly affected breeds.
Will neutering alone fix a urethral prolapse?
Neutering alone won’t correct the prolapse, but it’s an important part of the overall treatment plan. Surgery is needed to reposition or remove the prolapsed tissue, and neutering helps prevent it from recurring.
What happens if urethral prolapse comes back after surgery?
Recurrence is possible, especially in intact dogs or those with ongoing urinary issues. A second procedure may be needed, which is why neutering and managing any underlying straining causes are so important after the first repair.
