What Causes Peeling and Flaking of a Dog's Testicles?

A number of conditions can lead to peeling and flaking skin on your dog's testicles and scrotum. The most common causes include:

External Parasites

  • Mites: The sarcoptic mange mite burrows into the skin and causes intense itchiness and hair loss. The mites prefer hair follicles on the legs, abdomen and chest but can spread to the testicles.
  • Lice: Canine lice feed on skin and secretions, leading to hair loss, inflammation, and crusting on the testicles. Lice spread through close contact with other dogs.

Fungal Infections

  • Ringworm: A fungal infection that appears as circular, red, itchy patches that may peel or flake. Ringworm thrives on the groin, legs and testicles.

Bacterial and Yeast Infections

  • Staphylococcal hypersensitivity: A bacterial skin infection causing crusty sores with scales and hair loss on the testicles.
  • Yeast dermatitis: Overgrowth of yeast on moist skin folds like the scrotum leads to greasy, smelly skin and peeling.

Allergic Reactions

  • Contact dermatitis: An allergic reaction to grooming products, chemicals, fabrics or grass can lead to red, flaky skin on the testicles.
  • Food allergies: Allergies to proteins in dog food can cause uncomfortable skin inflammation and peeling on the genitals.

Hormone Disorders

  • Hypothyroidism: Low levels of the thyroid hormone result in dry, scaly, peeling skin all over the dog's body, including the testes.
  • Hyperadrenocorticism: Excess cortisol levels damage the skin leading to thin skin and hair loss on the testicles.

Other Causes

  • Foreign material: Dirt, debris or grass seeds stuck in the skin folds can cause irritation, infection and peeling.
  • Chemical irritation: Pesticides, lawn fertilizers or harsh shampoos can trigger skin reactions on delicate genital skin.
  • Dry skin: Lack of moisture and oil makes testicular skin extremely dry, tight and flaky.
  • Sunburn: Prolonged sun exposure can burn and peel the thin genital skin of dogs not protected by fur.
  • Trauma: Injuries from scratches, bites or accidents can damage the scrotal skin.

What Symptoms Accompany Peeling Testicles in Dogs?

Peeling or flaking skin on your dog's scrotum or testicles is often accompanied by other worrying symptoms:

  • Redness and inflammation – The skin appears red and inflamed indicating irritation.
  • Itchiness – Frequent scratching at the area suggests it's very itchy and uncomfortable.
  • Hair loss – Visible patches of hair loss around the testicles may occur.
  • Crusty or scaly texture – Dry, crusty deposits develop indicating abnormal skin shedding.
  • Greasy residue – A yellowish, greasy substance may coat the testicles.
  • Odor – In yeast infections, a distinct yeasty smell emanates from the testicles.
  • Pain – Dogs may whimper or snap if the area is touched due to tenderness.
  • Skin thickening – Certain hormonal disorders can cause the scrotal skin to thicken.
  • Blisters or sores – Bacterial infections may be accompanied by pustules or skin ulcerations.

How Do Veterinarians Diagnose the Cause of Peeling Testicles?

If you notice peeling or flaky skin on your dog's testicles, the following diagnostic tests will be used to pinpoint the underlying cause:

Physical Exam

The vet thoroughly inspects the extent of hair loss, peeling, inflammation and other symptoms affecting the testicles and surrounding region. They'll check for parasites, wounds, or abnormal discharge associated with infections.

Skin Scrapings

The vet uses a scalpel blade to gently scrape cells and secretions from affected areas onto a microscope slide. This helps identify parasites like mites as well as fungal infections.


Skin cells and oil collected using cotton swabs are stained and examined under the microscope. The cellular features help diagnose bacterial, fungal and yeast infections.

Skin Biopsy

A small sample of the abnormal testicular skin is extracted and sent to the lab for biopsy. Microscopic examination of the tissue helps identify skin disorders.

Bacterial Culture

Infectious bacteria are isolated from the peeling skin and grown in cultures in the lab to allow identification and antibiotic sensitivity testing.

Blood Tests

Blood work helps determine thyroid levels, adrenal function, blood cell counts and biochemistry parameters. This identifies any hormonal issues or systemic disorders.

With these diagnostic tests, vets can definitively diagnose the specific cause of your dog's peeling testicles whether it's mites, allergies, infections or hormone abnormalities.

What Treatments Can Relieve Peeling and Itching of the Testicles?

The appropriate treatment will depend on the exact cause diagnosed by your vet:

Medicated Shampoos and Dips

  • Antibacterial and antifungal shampoos treat underlying fungal, yeast or bacterial infections.
  • Sulfur lime dips kill parasites like sarcoptic mange mites on the testicles.
  • Colloidal oatmeal shampoo soothes inflammation and itching.
  • Medicated wash with chlorhexidine and ketoconazole has anti-fungal, antibacterial and anti-yeast action.

Oral and Topical Medications

  • Ivermectin eliminates mites, lice and other parasites.
  • Antibiotics target bacterial infections.
  • Antifungal drugs clear fungal or yeast infections.
  • Anti-inflammatories like steroids help control itching and discomfort.
  • Immunosuppressants manage contact or food allergies.
  • Topical ointments provide soothing relief while treating the skin.

Hormone Replacement Therapy

  • Hypothyroid dogs are treated with oral thyroid hormone replacement medications.
  • Cortisol inhibiting drugs help manage Cushing's disease.

Diet Trials

Hypoallergenic diets help determine food allergies causing skin reactions.

Environment Control

Eliminating fabric softener, yard chemicals and other irritants aids in contact dermatitis. Grooming tools should be sterilized.

With appropriate treatment guided by a veterinary dermatologist, the peeling and itching can be controlled allowing your dog's testicles to heal. Make sure to finish the entire course of prescribed therapy. Follow up with your vet to ensure the problem is resolved.
