Ichthyosis is an autosomal recessive genetic mutation that affects the skin of Golden Retrievers. The mutation prevents the outer layer of the epidermis from forming properly, resulting in skin that becomes darkened and thick, with excessive flaking.
The name "Ichthyosis" is derived from the Greek word for fish. This describes the skin's resemblance to fish scales. The most common symptom of ICT-A is excessive flaking of the skin. Other symptoms include areas of hardened skin and hyperpigmentation, which may make the skin appear dirty or blackened. Symptoms can be mild or severe. Evidence of the disease may be detected when the dog is still a puppy, but symptoms may take a year or more to develop. Additionally, symptoms can improve or worsen, depending on stress and hormonal cycles.
Ichthyosis is generally not dangerous to a dog's health, but can be unsightly and uncomfortable for the dog. A dog diagnosed with ICT-A will usually require more care with special shampoos and treatments.
There is a also more severe form of Ichthyosis : Ichthyosis Type 2
