Paraphimosis in Dogs: Symptoms, Causes, and Treatment

Paraphimosis in Dogs

Paraphimosis in Dogs: Paraphimosis refers to a medical condition in which a dog’s penis cannot be retracted back into the prepuce or foreskin. The swelling and inflammation cause the narrow opening of the prepuce to constrict, trapping the penis outside the body. This can quickly become a medical emergency if left untreated.

If your male dog’s penis is protruding from the prepuce and swollen, it’s likely suffering from paraphimosis. Some possible symptoms include:

  • Swollen, irritated penis that remains outside the prepuce
  • Discharge or bleeding from the penis
  • Licking or biting at the penis
  • Restlessness or anxiety
  • Urinating difficulties

Several factors can lead to paraphimosis in dogs:

  • Improper preputial opening: If the preputial opening is too narrow, it can constrict around the penis. This is common in young dogs and certain breeds like Bulldogs.
  • Infections: Bacterial infections of the prepuce or penis can cause inflammation and swelling, leading to paraphimosis.
  • Trauma: Any trauma or damage to the penis or prepuce may trigger paraphimosis. Rough play or mating injuries are often to blame.
  • Long walks: Extended walks or exercise can cause the penis to become engorged with blood, enlarging it so it gets stuck outside the prepuce.
  • Lack of preputial muscle tone: Weakness or lack of muscle control prevents the prepuce from retracting normally over the penis. This is seen more often in older dogs.

The good news is paraphimosis can usually be easily treated by a vet. They will examine your dog, reduce the swelling, and guide the penis back into the proper position. Antibiotics, anti-inflammatories, and medication may also be prescribed based on the underlying cause. With prompt treatment, most dogs recover fully from paraphimosis.

Causes and Risk Factors for Paraphimosis

Several factors can increase a dog’s risk of developing paraphimosis or make them more prone to the condition. The most common causes and risk factors include:

  • Inflammation or trauma of the prepuce. The prepuce is the loose fold of skin that covers the penis. Any swelling, irritation, or injury to this area can cause the prepuce to tighten around the penis, making it difficult to retract. Things that can lead to preputial inflammation include infections, allergic reactions, trauma from mating, or debris caught under the prepuce.
  • Obesity. Overweight dogs have more tissue surrounding the prepuce, making it more likely to swell and tighten. Losing excess weight can help prevent recurrences of paraphimosis.
  • Anatomical abnormalities. Certain breeds like Bulldogs, Pekingese, and Chow Chows have narrow preputial openings that can predispose them to paraphimosis. Dogs that have been improperly neutered at a young age may also have anatomical changes that increase the risk.
  • Lack of preputial mobility. If a dog’s prepuce is not regularly retracted and manipulated from an early age, it may tighten and lose elasticity over time. Gently retracting and massaging a puppy’s prepuce from an early age can help prevent paraphimosis later on.
  • Chronic disorders. Conditions like Cushing’s disease, diabetes, adrenal disease, and hypothyroidism can cause changes in hormones and connective tissues that may lead to paraphimosis. Managing the underlying disease can help reduce flare-ups.

By understanding the causes and risk factors for paraphimosis, you can take steps to prevent this condition in your dog or minimize recurrences if he develops it. Be on alert for any irritation, swelling or trauma to the prepuce area and have your vet examine your dog right away. Keeping your dog at a healthy weight, retracting his prepuce regularly, and properly managing any chronic diseases can all help lower his risk of paraphimosis.

Recognizing the Symptoms of Paraphimosis

Paraphimosis happens when a dog’s foreskin gets stuck retracted behind the glans penis, causing the blood flow to become constricted. This is a medical emergency, so knowing the signs to look for is critical. If you notice any of these symptoms in your dog, contact your vet immediately.

One of the first symptoms you may notice is swelling of the penis and foreskin. The constricted blood flow causes fluid buildup, resulting in significant swelling and inflammation. The penis and foreskin will appear very swollen, puffy and tender. Your dog may seem uncomfortable and lick or bite at the area frequently.

Difficulty urinating or blood in the urine can also occur. The constriction can make it hard for your dog to pass urine, or may only allow urine to dribble out. You may also see drops of blood in the urine or on the fur around the prepuce.

Discharge from the prepuce is another symptom to watch for. A foul-smelling, pus-like discharge may seep from the prepuce as infection sets in. The discharge is usually thick, yellow or green, and very smelly. Infection must be treated quickly to avoid complications.

If the condition is left untreated, tissue damage and even gangrene can develop. The lack of blood flow and oxygen causes the tissues of the penis and prepuce to start dying off. This is an emergency situation and requires immediate unblocking of blood flow and surgical removal of damaged tissue.

Treatment Options for Paraphimosis in Dogs

If paraphimosis occurs in your dog, take them to the vet immediately. The vet will examine your dog and determine the underlying cause of the inflammation before proceeding with treatment. There are a few options to provide relief and correct the problem.

Manual reduction

The vet will first try manually manipulating the swollen tissue to return the dog’s foreskin to its normal position over the glans. They will apply a lubricant and gently squeeze and massage the edema to reduce swelling and pull the foreskin forward. This method is usually effective, especially if addressed promptly. However, repeated episodes may require surgery.

Cold compresses

Applying cold compresses to the swollen area can help reduce inflammation, relieve discomfort, and make manual reduction easier. The vet may recommend doing this for 10-15 minutes, a few times per day until the swelling goes down. Be very gentle to avoid further irritation.

Anti-inflammatory medication

The vet may prescribe oral or topical anti-inflammatory medication such as corticosteroids to decrease swelling. This can help make other treatments more effective and provide pain relief for your dog. Follow all dosage and administration instructions carefully.


In severe or chronic cases, or if other treatments are not effective, surgery may be recommended to prevent future episodes of paraphimosis. The most common procedure is circumcision, the surgical removal of part or all of the foreskin. Circumcision eliminates the foreskin so it cannot become trapped behind the glans again.

Recovery and aftercare will depend on the treatment method. Be sure to keep the area clean, limit activity, and return for follow-up appointments as directed. With prompt diagnosis and treatment, paraphimosis can be fully corrected and future episodes prevented.
