Canine Disease Information: Schnauzer Comedo Syndrome



  • Type Disease
    Skin
  • Name
    Schnauzer Comedo Syndrome
  • Abbreviation
    SCSx
  • Description
    Dogs with this syndrome have multiple comedones on their backs. These plugs of keratin and sebum block the hair follicles, and are commonly called blackheads.
  • How Transferred
    The mode of inheritance is unknown.
  • What to Look for
    Animals with this syndrome have bumps, scabs and blackheads on their backs, which may only be noticed when the hair is clipped. These usually do not bother the dog unless a secondary bacterial skin infection develops, causing some pain and itching.\nThe dog's general health is not affected.
  • Diagnosis
    The diagnosis is readily made based on finding comedones or blackheads along the back of a miniature schnauzer. Your veterinarian may take a skin biopsy to confirm the diagnosis. This is a simple procedure done with local anesthetic, in which your veterinarian removes a small sample of your dog's skin for examination by a veterinary pathologist.
  • Treatment
    This condition can not be cured but it can be controlled. Mild cases need no treatment. In other cases or where there are repeated infections, regular cleaning with acne cleaning products or mild anti-seborrheic shampoos will be required. Your veterinarian will work with you to find a regime suitable for your dog.\nIf a secondary bacterial infection develops, your dog will need to take antibiotics for 3 or 4 weeks.\nFor the veterinarian: Refractory cases may respond to retinoid therapy.
  • Breeding Considerations
    It is preferable not to breed affected dogs, in order to reduce the occurrence of this common disorder in miniature schnauzers.
