Schnauzer Comedo Syndrome in Dogs

Schnauzer Comedo Syndrome, also known as Schnauzer Bumps, is a skin disorder which only affects Schnauzers. These bumps are wart-like in appearance or may look like pimples or blackheads. They typically flare up on the back of the dog, mainly down the spine. They are not contagious and are not harmful to the Schnauzer.

These bumps may vary in appearance from dog to dog; some may be pus-filled, some may have slight oozing fluid, and some may not have either.  Black-centered bumps may be apparent in certain cases, and in other cases they may crust over. The Schnauzer’s skin may also be scaly in addition to having the bumps.

The frequency and the severity of the bumps depend on each dog. For certain Schnauzers, the bumps may only appear sporadically or frequently and consistently. They do not harm the dog’s overall health, but can be slightly uncomfortable in some cases. Luckily, there are specific types of shampoos and topical solutions that can help minimize any discomfort. There is no cure for this condition, but it can be controlled with the help of a veterinarian.

Schnauzer Comedo Syndrome in dogs is a genetic condition in which miniature Schnauzers develop bumps on the skin, typically along the back. This condition is not a harmful condition and only affects the appearance of the skin.

Symptoms of Schnauzer Comedo Syndrome will vary from dog to dog, in both appearance and discomfort. Symptoms may include:

• Black, crusty bumps on the back
• Raised pimple-like or wart-like spots on the back
• Hair loss
• Skin thickening
• Itchiness
• Red and irritated patches of skin
• Possible strong odor

Types

There are several different skin conditions which can occur that may be confused with Schnauzer Comedo Syndrome or have similar characteristics. Differential diagnoses include:

• Skin allergies
• Food reactions
• Flea dermatitis
• Bacterial infection
• Fungal infection
• Ectoparasites

Causes of these bumps are breed-specific. Causes may include:

• Predisposition
• Genetics
• Blocked sebaceous glands

If your Schnauzer is showing signs of bumps along his back, make an appointment with your veterinarian. Once you arrive, the veterinarian will take a close look at your dog’s skin. He may then perform preliminary testing, such as blood work, urinalysis and biochemistry profile to check your dog’s overall health. Before he moves on, he may want to rule out any other health conditions.

He will ask questions pertaining to when you first noticed the bumps and the frequency of the flare ups. He may also want to know information about your dog’s environment, sleeping conditions (such as bedding type), and diet. He will also want to be sure your dog gets plenty of water throughout the day due to proper electrolyte content within your dog’s system. Dogs who do not have plenty of water can become dehydrated and can be at risk for scaly skin.

Typically, your veterinarian will be able to come to a diagnosis by visual observation and the knowledge of this condition. The veterinarian may clip a small area of his hair so he can take a closer look at the papules on his back. He may also scrape the skin to retrieve a sample in order for it to be tested. The biopsy will confirm this diagnosis if there is a plug blocking the follicle of the hair and the sebaceous gland. This plug may be filled with sebum and keratin and have a secretion. It will look like a very small cyst.

Once your miniature schnauzer is diagnosed with this condition, your veterinarian will outline several treatment options for your companion. Treatment methods may include:

Antibiotics

If there is a secondary infection due to infected pustules on your dog’s skin, your veterinarian may prescribe an antibiotic for 2 to 3 weeks. Your veterinarian will recommend the appropriate antibiotic for your companion.

Topical Medications or Agents

Consistent cleaning using alcohol, antiseptic, or even cleaning pads for people can help dissolve and loosen the comedones. Other topical ointments such as benzoyl peroxide and anti-seborrheic shampoos may also be used. It is important to use only the mildest of shampoos or topical ointments due to the fact that the follicles which are plugged may become inflamed by harsher substances. Your veterinarian may also suggest that you combine several of these topical substances.

Consistent Monitoring

Since there is no cure for this condition, consistent upkeep can help keep the bumps to a minimum. Consistent care and monitoring of your dog’s affected areas may help keep any flare ups from occurring. Your veterinarian may suggest keeping the hair very short in the affected areas and bathing your dog frequently.

Vitamin Supplements

Vitamin A supplements may help control your Schnauzer’s condition. You may want to ask your veterinarian if supplements of 600-800 IU/kg once a day can help. You should not give your dog vitamin supplements without your veterinarian’s consent.

Fortunately, this condition is not harmful to your Schnauzer; it does cause his skin to lack a healthy appearance, but it can be controlled.

If your veterinarian has given you suggestions for maintaining the bumps and preventing flare ups, follow his advice. It is important to not give your dog any medications or holistic treatments without consulting with your veterinarian first. If you do choose to see if any holistic supplements will work for your dog, your veterinarian may be able to recommend some for you.

Your Schnauzer will live a long and happy life with this condition. If it is managed well by you, it will be devoid of any secondary infection or inflammation. It will be important to monitor the bumps and be sure they are cared for with the advice of your veterinarian.
