A colour seen in of a dog's coat - Bluish gray colouring with flecks of black, as in a "blue-merle" Collie
pattern of coloring observed in the coat of the domestic dog and is characterized by patches of diluted pigment. Dogs inherit trait in an autosomal, incompletely dominant fashion and heterozygous or homozygous for the merle locus exhibit a wide range of auditory and ophthalmologic abnormalities, similar to those in human Waardenburg syndrome.

Merle is a colour combination in dogsâ€™ coats. It is a solid base color (usually red/brown or black) with lighter blue/gray or reddish patches, which gives a mottled or uneven speckled effect. Although most breeds that can have merle coats also typically have white markings (such as around the neck, under the belly, and so on), and often tan points (typically between the white and the darker parts of the coat), these are separate colors from the merle; some dogs do appear completely merled with no white or tan markings.
