Understanding Sebaceous Adenitis in Dogs

Sebaceous adenitis (SA) is a hereditary skin disease that affects the sebaceous glands, leading to various skin problems. It is particularly common in breeds such as Standard Poodles, Akitas, and Samoyeds, though it can also occur in other breeds and mixed breeds.

What is Sebaceous Adenitis?

Sebaceous adenitis is an inflammatory condition targeting the sebaceous glands in a dog's skin. These glands produce sebum, an oily substance that helps keep the skin and coat healthy. When these glands become inflamed, they can be destroyed, resulting in symptoms such as hair loss, dandruff, a distinct odor, and secondary skin infections.

The onset of sebaceous adenitis can occur at any age, with reported cases starting as early as one year and as late as 12 years. Both male and female dogs are equally susceptible to this condition. The exact genetic transmission of the disease remains unknown.

Symptoms of Sebaceous Adenitis

Diagnosing sebaceous adenitis can be challenging because its symptoms often mimic other skin conditions like hypothyroidism, allergies, parasitic infections (such as Demodex), and hormonal disorders. Symptoms can vary widely in severity and presentation, depending on the breed and individual dog.

Typical symptoms include:

  • Progressive hair loss

  • Flaky skin or dandruff

  • A musty or rancid odor from the skin

  • Thickened skin and crusting

  • Secondary bacterial or fungal infections

As there is no DNA test available for sebaceous adenitis, diagnosis relies on a skin biopsy performed by a veterinarian. However, because the disease can manifest at different ages and with varying severity, even a biopsy can sometimes produce false negatives. Therefore, for dogs in breeding programs, it is recommended to repeat biopsies every one to two years to monitor for the disease.

Treatment for Sebaceous Adenitis

Treating sebaceous adenitis is complex and often requires a combination of topical and oral therapies. The response to treatment can vary significantly between dogs, and it may take several months to determine the effectiveness of the chosen therapies.

Topical Treatments:

  • Medicated baths and shampoos: These help to soothe the skin and remove excess flakes and crusts.

  • Sprays, rinses, and soaks: These can help to manage the symptoms and keep the skin clean.

Oral Treatments:

  • Essential fatty acid supplements: These can help to support overall skin health.

  • Cyclosporine: This prescription medication helps to modulate the immune system and reduce inflammation.

  • Synthetic retinoids: These vitamin A derivatives are prescribed to help normalize skin cell production.

Steroids, such as prednisone, are generally avoided as they often do not provide improvement and can sometimes exacerbate the condition.

Managing Sebaceous Adenitis

Management of sebaceous adenitis requires a tailored approach and ongoing veterinary care. Early and consistent treatment can help manage the symptoms and improve the quality of life for affected dogs. Regular follow-ups with a veterinarian are crucial to adjust treatment plans as needed.
