Condition Overview

This is an inherited skin disease controlled by an autosomal recessive gene that adversely affects the development of sebaceous glands. Predisposed breeds include the Standard Poodle, Akita, Samoyed, and Vizsla.

Symptoms

Signs usually appear in the first 4 years of life, but may develop later. Longhaired breeds such as the Standard Poodle have areas of symmetrical hair loss involving the muzzle, top of head, ear flaps, and the top of the neck, trunk, and tail.

The skin develops a scaly seborrhea, and in advanced cases a bacterial infection of the hair follicles. Shorthaired breeds such as the Vizsla have circular areas of hair loss with scaling on the head, ears, trunk, and legs.

Causes

This is an inherited skin disease controlled by an autosomal recessive gene that adversely affects the development of sebaceous glands.

Diagnosis

The diagnosis is confirmed by skin biopsy.

Treatment

Treatment involves corticosteroids, Accutane (isotretinoin), and a number of anti-seborrhea (anti-dandruff) and anti-follicular drugs and shampoos that can be prescribed by your vet.

Prevention

The Institute for Genetic Disease Control in Animals maintains a registry for sebaceous adenitis in Standard Poodles. The OFA has taken over much of the sebaceous adenitis data and registry.

Dogs with sebaceous adenitis and those identified as carriers should not be bred.
