Sebaceous Adenitis in Dogs

Not all skin problems in dogs are due to allergies, mites or other environmental factors. Genetics can also play a role in your dog's skin condition.

Sebaceous adenitis (SA) in dogs is a hereditary skin disease in which the sebaceous glands of the skin surface become inflamed, often leading to progressive loss of hair, dandruff, odor, and infections. The disease is primarily seen in Standard Poodles, Akitas, and Samoyeds, although there have been reported cases in other breeds and mixed breeds as well.

Canine sebaceous adenitis can develop at any age, with age of onset documented as early as one year and as late as 12 years. Males and females appear to be affected equally and the exact mode of inheritance is unknown.

Sebaceous adenitis is rare and can be difficult to diagnose as the symptoms vary by breed. It can look like hypothyroidism, allergies, parasites and other hormonal disorders, and can vary greatly in its severity. At this time, there is no DNA test available to detect sebaceous adenitis. Currently, diagnosis is based on skin biopsy samples performed by a veterinarian. In some dogs, the current screening method may result in false negatives. Because the age of onset varies, and since this is only a phenotypic test reflecting a point in time, retesting is recommended every one to two years for dogs used in breeding programs.

For dogs that do test positive, treatment for sebaceous adenitis is complicated. Unfortunately, there is no one treatment option that is effective for all dogs with sebaceous adenitis. It is best to talk with your veterinarian about what treatment might work best for your dog.
