Ichthyosis
Ichthyosis is derived from the Greek root “ichthy,” meaning fish, and was so named due to the visible scales on the skin. Affected dogs may develop generalized severe greyish scales, mild redness of the skin, less hair than normal, and specific areas of hair loss. Dogs may also have blackheads on their belly. Some dogs develop secondary bacterial skin infections that may make diagnosis difficult and contribute to itching.

Signs and symptoms
Affected dogs typically have large, greasy flakes of dandruff but aren't itchy. The scales of skin can get so thick that they can crack and cause fissures, leading to considerable discomfort.
As puppies, affected dogs can show signs of scaling. This disease tends to worsen with age.Uncover health risks with Embark

Diagnosis
Examining the characteristic lesions is the first step in diagnosing Ichthyosis. Confirmatory genetic testing and/or skin biopsies can also be performed.
-
Treatment
There is no definitive treatment for Ichthyosis: typically, ichthyotic dogs are maintained on the continuous treatment of mild anti-dandruff shampoos and moisturizing rinses. This is a chronic and frustrating condition to manage.
