A merle coat has a mix of shades in patches on the dog’s coat. The extent of these shades and patches depends on genetics.
How Can a Goldendoodle be Merle?
As a cross between Poodles and Golden Retrievers, merle Goldendoodles get their merle genetics from the Poodle.
Also referred to as black merle, a blue merle Goldendoodle has BB, a dominant gene, for its black pigment coloration, as well as DD for merle that is black with blue or white.
Also called liver merle, a red merle Goldendoodle can include fawn or isabella coloration with dilution. These dogs have bb for their pigment coloration, resulting in a beautiful reddish-brown color.
Referred to as tan or chocolate merle, sable merle has bb coloration and two specific genetics for agouti.
