Seborrhea by Jennie Bullock  

        Seborrhea is a disorder of the surface layers of the skin and/or the oil glands of the skin.  Seborrhea occurs in two forms : primary (seborrhea oleosa) and secondary (seborrhea sicca).  Seborrhea can be a primary skin disorder, or a manifestation of some other medical problem.  Problems such as hypothyroidism, endocrine disease, dietary deficiency, allergies, internal or external parasites, cancer, immune disorders, bacterial infections, or fungal infections can all exhibit seborrhea as a symptom.

        Seborrhea sicca is similar to dandruff. this forms presents itself as white or grayish white scales, accompanied by dry skin and a dull, dry coat.  The scales lift easily off the skin.  The dog usually has a severe scratching problem. Seborrhea sicca is most often symptomatic of an underlying cause.

        Seborrhea oleosa normally consists of yellow or yellow brown scales.  These scales are frequently clumped to the hair.  The dogs coat and skin has a greasy feel.  Since seborrhea oleosa is associated with the excess production of sebum (skin oil), the dog will usually have a rancid oil smell.  Many dogs affected with seborrhea oleosa have recurrent ear problems, itching skin and skin infections.

        Primary seborrhea is incurable, it is however controllable.  Anti-seborrhea veterinary shampoos, creams, ointments, cortisone, and antibiotics all contribute to the repertoire for combating this problem.
