Preputial Inflammation in Male Dogs

Balanoposthitis is a widespread issue in veterinary practice that can affect male dogs of all ages and breeds. Although often dismissed as a minor ailment, chronic or recurrent balanoposthitis can significantly impact the quality of life of affected animals and presents a challenge for both veterinarians and pet owners. This article aims to provide you with a comprehensive overview of the etiology, clinical signs, diagnosis, and therapy of preputial inflammation, offering practical tips for your daily practice.

Etiology: Causes and Predisposing Factors

The causes of preputial inflammation are diverse and can be both infectious and non-infectious. Common predisposing factors include:

Bacterial Infections: Various bacteria, including Staphylococci, Streptococci, and Escherichia coli, can cause inflammation of the prepuce.
Fungal Infections: Yeasts, particularly of the genus Malassezia, can play a role in immunocompromised animals or in the presence of skin irritations.
Viral Infections: Herpesviruses can, in rare cases, also cause balanoposthitis.
Foreign Bodies: Foxtails, grains of sand, or other foreign bodies that enter the prepuce can lead to irritation and inflammation.
Anatomical Anomalies: Narrow prepuce (phimosis), preputial constriction (paraphimosis), or other anomalies can impair the self-cleaning function of the prepuce and promote infections.
Allergies: Allergic reactions to food components, environmental allergens, or contact allergens can lead to inflammation of the skin and mucous membranes of the prepuce.
Trauma: Injuries to the prepuce, e.g., from bites or bumps, can cause inflammation.
Hormonal Factors: In intact male dogs, elevated testosterone levels can stimulate sebum production in the prepuce, thus promoting bacterial growth.

Clinical Symptoms: What to Look Out For

The symptoms of preputial inflammation can vary depending on the severity of the inflammation. Common clinical signs include:

Discharge: Purulent, serous, or bloody; may vary in severity.
Licking at the Prepuce: Increased licking due to itching or irritation.
Redness and Swelling: Signs of inflammation in the area of the prepuce.
Painfulness: Sensitivity to pain upon touching or manipulating the prepuce.
Unpleasant Odor: Foul-smelling odor from the prepuce.
Pollakiuria: Increased urination, often in small amounts.
Dysuria: Painful urination.
Restlessness: General restlessness or irritability.
Changes in General Condition: In severe cases, fever, loss of appetite, and apathy may also occur.

Diagnostics: How to Determine the Cause

A careful history and clinical examination are crucial for diagnosis. The following diagnostic measures may be useful to clarify the cause:

Cytological Examination: Microscopic examination of the discharge to assess cell types and detect bacteria or fungi.
Bacteriological Examination: Setting up a bacterial culture with an antibiogram to identify the bacteria involved and determine antibiotic susceptibility.
Allergy Test: Performing an allergy test (e.g., serum test or intradermal test) if an allergic origin is suspected.
Blood Test: Performing a blood test to assess the general condition and rule out systemic diseases.
Endoscopy: In rare cases, an endoscopy of the prepuce may be useful to assess the mucous membrane and rule out foreign bodies or tumors.

Therapy: Individual Treatment Concepts

The therapy for preputial inflammation depends on the underlying cause. The following treatment measures may be considered:

Cleaning of the Prepuce: Regularly rinsing the prepuce with a mild, antiseptic solution (e.g., based on hypochlorous acid).
Antibiotic Therapy: Systemic or local application of antibiotics for bacterial infections (according to the antibiogram).
Antifungal Therapy: Local or systemic application of antifungals for fungal infections.
Removal of Foreign Bodies: Careful removal of foreign bodies under sedation or anesthesia.
Castration: In intact male dogs, castration can reduce sebum production, thus reducing bacterial growth.
Allergy Management: Food change, hyposensitization, or use of antihistamines for allergic reactions.
Surgical Intervention: In rare cases, surgical correction of anatomical anomalies (e.g., phimosis) may be necessary.

Prevention: Preventive Measures for a Healthy Prepuce

Good preputial hygiene can help prevent inflammation and avoid relapses. You can recommend the following measures to your patients’ owners:

Regular Cleaning: Regularly rinsing the prepuce with a mild, antiseptic solution.
Avoidance of Irritants: Avoid contact with potential allergens or irritants.
Regular Checks: Carry out regular checks of the prepuce to detect changes early.
Early Treatment: Treat inflammation early to prevent it from becoming chronic.

Conclusion:

Preputial inflammation is a common and often underestimated problem in small animal practice. A careful history, clinical examination, and, if necessary, further diagnostics are crucial for determining the cause and establishing an individual therapy plan. Through a combination of causal therapy and preventive measures, you can help your patients lead a comfortable life free from discomfort.
