Black and Self Color

Black is known as a self-color, that is the entire animal is one color, with extreme black pigmentation of the coat. In poms it is usually caused by the dominant K allele, although there are some reported cases of recessive black (a) in the breed.

Other Self-Colors

The presence of other recessives can turn the solid black dog to other variations, such as solid chocolate (bb) and blue (dd) and, when both are on the same dog, isabella/lavender (bbdd). In addition, the presence of two recessive clear orange (ee) genes can result in a clear orange dog that can disguise the presence of the black K gene completely.
