What is Schnauzer comedo syndrome?
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 is Schnauzer comedo syndrome inherited?
The mode of inheritance is unknown.
What breeds are affected by Schnauzer comedo syndrome?
Miniature schnauzer
For many breeds and many disorders, the studies to determine the mode of inheritance or the frequency in the breed have not been carried out, or are inconclusive. We have listed breeds for which there is a consensus among those investigating in this field and among veterinary practitioners, that the condition is significant in this breed.
What does Schnauzer comedo syndrome mean to your dog & you?
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.
The dog's general health is not affected.
How is Schnauzer comedo syndrome diagnosed?
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.
How is Schnauzer comedo syndrome treated?
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.
If a secondary bacterial infection develops, your dog will need to take antibiotics for 3 or 4 weeks.
For the veterinarian: Refractory cases may respond to retinoid therapy.
It is preferable not to breed affected dogs, in order to reduce the occurrence of this common disorder in miniature schnauzers.
