Coat colour, dominant black(KB)
Also known as: Dominant Black · K Locus · KB allele · Dominantes Schwarz · K-Lokus
Overview
What it is
This is a non-pathological genetic trait rather than a disease, located at the K locus (specifically the CBD103 gene) which influences the dog's coat. It works by regulating the distribution of eumelanin, which is the dark pigment responsible for black or brown coloration in the hair follicles. Because it is inherited in an autosomal dominant manner, a dog only needs one copy of this gene variant to express a dark coat.
How it presents
From birth, dogs with this trait will display a solid black coat, or a color-modified version like solid brown depending on other genes. This is a purely cosmetic trait that remains constant throughout the dog's life and has no negative health implications.
Treatment
Because this is a normal, healthy physical characteristic rather than a medical condition, no treatment is required. There are no associated medical costs, resulting in a lifetime treatment cost of 0 EUR.
