Canine Sebaceous Adenitis (SA) is a skin disorder that affects a dog’s sebaceous glands. Sebaceous Adenitis is an autoimmune disorder, meaning that the body’s immune system mistakenly attacks its own healthy cells and tissues. The sebaceous glands produce sebum, which is an oily substance that helps keep their skin and coat healthy. When these glands are attacked by the immune system, they become inflamed and are unable to produce sebum. This leads to dry, scaly skin and hair loss.
SA can affect any dog breed, but is most commonly seen in Akitas, Standard Poodles, German Shepherds, and Labrador Retrievers. It’s also more common in males than females. The exact cause of SA is unknown, but it is believed to be related to genetics, environmental factors, or a combination of both.
Diagnosing Sebaceous Adenitis is typically made through a combination of physical examination, skin biopsy, and laboratory tests. During the physical examination, the veterinarian will look for signs of hair loss and scaling on your dog’s coat. The skin biopsy involves taking a small sample of tissue from the affected area and examining it under a microscope to look for changes in the sebaceous glands. Laboratory tests may also be used to look for specific antibodies associated with SA.
Symptoms of Canine Sebaceous Adenitis
The most common symptom of SA are:
- Dry
- Scaly skin
- Hair loss
Other signs may include:
- Itching
- Redness
- Musty odor
In severe cases, the affected area may become thickened and crusty.

Stages of Canine Sebaceous Adenitis
Canine Sebaceous Adenitis can be split into three stages:
Stage 1
Mild inflammation of the sebaceous glands. This stage is associated with dry, scaly skin and mild hair loss.
Stage 2
Moderate inflammation of the sebaceous glands. This stage is associated with more severe hair loss and their skin thickening.
Stage 3
Severe inflammation of the sebaceous glands. This stage is noted for severe hair loss, skin thickening, and crusting.
Treating Canine Sebaceous Adenitis
Treatment for SA depends on the severity of the condition. Mild cases can be managed with topical medications and shampoos that help reduce inflammation and restore their skin’s moisture. In more severe cases, systemic medications such as antibiotics or immunosuppressants may be necessary. In some cases, surgery may be recommended to remove affected tissue.
It’s important to note that SA is a chronic condition and may require lifelong management. It’s also important to know that SA can be very difficult to treat and may not respond to treatment in some cases.
Preventing Canine Sebaceous Adenitis
Unfortunately, there is no known way to prevent SA in dogs. It’s important to keep your dog’s skin and coat healthy by feeding them a balanced diet, regular grooming, and avoiding environmental irritants such as fleas or mites. It’s important to monitor your dog for any signs of skin irritations or hair loss and seek veterinary attention if these signs are present.
