Ichthyosis, ICH1
This skin disorder gets its name from the thick, darkly pigmented scales of skin ("ichthys" is Greek for "fish") that affected dogs display over most areas of the body, not including the head or extremities.
-
Signs and symptoms
Ichthyotic 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. -
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 a continuous treatment of mild anti-dandruff shampoos and moisturizing rinses. This is a chronic and frustrating condition to manage.
