Description
A double merle is created when two merle dogs are bred together. It doesn’t matter what color merle or what breed they are. If two merle dogs are bred together, each puppy in the litter has a 25% chance of being born a double merle. A double merle inherits the merle gene twice. One copy of the merle gene causes a marbling effect on the coat and creates lighter spots throughout the solid color coat. In a double merle, the marbling/lightening effect is doubled and the coat becomes predominantly white. Double merles also have a very high chance of being deaf, blind, or both because they lack pigment where it would normally be.
