Severity is mild to moderate to severe

  • Diagnosis Icon
    Requires a diagnosis by a veterinarian
  • Time to Cure
    Resolves: typically never. This is a chronic condition that requires lifelong management
  • Treatment Icon
    Manageable by a veterinarian and by the pet parent
  • Prevention Icon
    Do not breed affected dogs as it is believed to potentially be inherited
  • Spread Icon
    Transmission is not possible between animals nor to people
  • Lab Icon
    Diagnosis requires a physical examination. Skin scrapings, cytology or cultures may be recommended to rule out other skin conditions.

VERY COMMON IN
Although other breeds may be involved, this condition is typically seen in Miniature Schnauzers

Symptoms & Signs

Dogs with schnauzer comedo syndrome typically have raised, black, crusty bumps (comedones) all along the spine. There may also be pimples, wart-like lesions, patchy hair loss, and the skin may become thickened and red. In some dogs, the skin takes on an oily nature with a strong odor.

Diagnosis

The condition is usually diagnosed by history, breed, and physical examination findings. Visual inspection of the lesions is normally enough to diagnose this condition, but the veterinarian may recommend a skin scrape, culture, or biopsy to rule out any other potential causes to definitively diagnose the condition.

Causation

The exact cause of schnauzer comedo syndrome is not known but it is believed to be an inherited dysfunction of the hair follicle which causes the follicle to become dilated and blocked with keratin and oils leading to the development of blackheads (comedones) along with the potential for secondary bacterial skin infections. Although not life threatening, this condition affects the appearance and smell of the animal. In severe cases, secondary infections can develop.

Treatments

icon AT-HOME CARE
Treatment is primarily aimed at managing the condition. Comedo syndrome usually persists in varying degrees for the life of the pet affected by this disorder. Frequent cleaning with a veterinary antiseptic solution (chlorhexidine) or cleansing wipe may be recommended by your veterinarian to help loosen and soften the comedones. Medicated benzoyl peroxide or anti-seborrheic shampoos can work well and should be used on a regular basis, if recommended by your veterinarian. Regular brushing is recommended to help remove excess hair and dirt while helping to spread the natural oils in the dog’s skin and fur, however caution should be taken if skin lesions are present as they can be itchy or painful, especially if infected.
icon SUPPORTIVE CARE
Keep the dog well-groomed and treat or wash as directed by a veterinarian
icon MEDICATIONS
If a secondary bacterial infection develops, an antibiotic may be prescribed to treat the infection. Vitamin A and Omega-3 fatty acid supplements may also be recommended. Isotretinoin (Accutane) is a synthetic retinoid that is occasionally prescribed for refractory cases of schnauzer comedone syndrome. While many medications are often administered for ‘off-label’ or 'extra-label' use in veterinary medicine, it is important to know that off- or extra- label use of a medication can only be done by a veterinarian when there are no other more appropriate medications for a particular pet's circumstances. Your veterinarian must also know all vitamins, supplements, medications etc. your pet is taking to help avoid complications. You must also be sure to follow all instructions provided by your vet carefully and consult your veterinarian with any questions or concerns if they arise.
icon DEVICES
An Elizabethan collar (cone) may be used to prevent excessive licking or chewing at affected areas.
icon SPECIALISTS
A competent general practitioner usually manages most dogs with schnauzer comedo syndrome, although a veterinary specialist in dermatology may be necessary for refractory cases.

Cost Of Treatment

The cost of veterinary treatment can vary widely for a multitude of reasons, but s prescribed shampoos and medication may cost $50 to $150 each month depending on the size of the dog, the severity of the condition and length of treatment.

Recovery

Although this is usually a lifelong condition that needs to be managed, it is not detrimental to the health of the pet and the pet typically lives a normal life as long as any secondary infections are properly treated.

Monitoring

Dogs with this condition should be monitored closely for secondary bacterial skin infections and inflammation so medications recommended by your veterinarian can be started as soon as possible. For patients on isotretinoin treatment, blood testing will need to be performed every 6-12 months to monitor for potential side effects.

Prevention

Since this disease is genetically inherited, responsible breeding by removing affected dogs from a breeding program will help prevent this disease.
