Balanoposthitis (Inflammation of the Penis and Prepuce) in Dogs

Overview of Canine Balanoposthitis

Balanoposthitis is the medical term used to describe inflammation of the penis and prepuce (the sheath of skin on the belly of the dog that covers the penis). There are a variety of causes of balanoposthitis, including injuries, bacterial infections, phimosis (constriction of the prepuce opening so that the prepuce cannot be drawn back to expose the penis), and tumors. Balanoposthitis is one of the more common problems to affect the prepuce and occurs more frequently in intact (non-neutered) male dogs.

What to Watch For

Signs of Balanoposthitis in the dog may include:

• Yellow or yellow-green discharge (pus) visible at the tip of the penis or prepuce
• Sometimes bloody discharge from the prepuce or penis
• Possible swelling and inflammation around the penis/prepuce
• Excessive licking at the prepuce
• Discomfort
• Disinterest in breeding
• Possibly lethargy, fever and loss of appetite if a serious infection is present

Diagnosis of Balanoposthitis in Dogs

Careful inspection and examination of the entire prepuce and penis is of utmost importance and is often diagnostic. Your veterinarian will examine the area for injuries, foreign bodies and tumors. A thorough examination may require sedation or anesthesia of the animal, especially if the dog is painful in the area.

Baseline tests such as a complete blood count, biochemical profile and urinalysis are usually within normal limits unless a bladder, prostate, or systemic infection is present. Urine for urinalysis is usually retrieved from the bladder so that discharge from the balanoposthitis does not contaminate the sample.

Bacterial culture and cytologic analysis (examination under the microscope) of the discharge may be helpful in some cases.

Treatment of Balanoposthitis in Dogs

Treatment of mild balanoposthitis involves keeping the penis and prepuce clean and preventing the dog from licking and self-trauma through use of an Elizabethan collar. In more severe, chronic, or recurrent cases treatment options may include:

• Removal of the underlying cause if one is found, such tumors, adhesions or abnormal tissue
• Antibiotic therapy
• Daily irrigation of the preputial sheath with an antiseptic solution
• Infusion of antibiotic ointment directly into the preputial sheath
• Neutering the dog

Home Care and Prevention

It is important to follow the instructions given to you by your veterinarian. Continue therapy for the entire recommended time period.

Recurrence is common despite therapy, especially when a predisposing factor cannot be identified. It is felt that intermittent flushing of the prepuce and neutering the dog may be of some help in minimizing subsequent infections, although there are no guaranteed ways to prevent the condition.
