Coat colour, roan
Also known as: Roan pattern · Schimmelzeichnung · Roan coat · Ticking modifier · Blauschimmel · …
Overview
What it is
Roan is a harmless genetic coat pattern inherited in an autosomal-dominant manner, affecting the integumentary system which comprises the skin and hair. It occurs when white and colored hairs are finely mixed across the dog's body, creating a characteristic mottled or speckled appearance. This is a purely cosmetic trait with no underlying medical relevance or negative health effects.
How it presents
The pattern is typically not visible at birth, as puppies are born white, but it begins to develop and become noticeable during the first few weeks of life. It does not cause any physical symptoms, discomfort, or health impairments.
Treatment
Because this is a natural and healthy color variation, no medical treatment is required. There are no associated veterinary costs, resulting in a lifetime treatment cost of 0 EUR.
