Want to have my great dane to have puppys, no diseases or any problems. dad was solid black and mom was mantleHARLEQUIN to MANTLE: This is the preferred breeding, all things considered, as it does not produce the Dominant (deaf ) White Dane. Expect the litter to be about 1/2 mantle, 1/4 merle & 1/4 harlequins. So in a litter of 8, expect 2-3 harlequins, 1-2 merles & 4 mantles. If these black pigmented dogs carry for other pigments, you may get fawns with blazes, or blue instead of a black basecoat Piebald & colour-headed dogs can occur, especially when flashy dogs are used.
