Congenital ichthyoses comprise a heterogeneous group of genodermatoses characterized by abnormal desquamation over the whole body. Different genodermatoses can occur in different dog breeds.
In Golden Retrievers, dermatological signs include a mild, moderate or severe generalised scaling, initially with small to large whitish scales that progress to blackish scales. The ventral glabrous skin can be hyperpigmented and rough. Dermatological signs can be visible at as early as a few weeks of age.
