Can you breed a merle to a merle?
A double merle is created when two merle dogs are bred together. It doesn’t matter what color merle or what breed they are. … Double merles also have a very high chance of being deaf, blind, or both because they lack pigment where it would normally be. The pups that do not inherit the gene twice are “normal” dogs.
Why is merle breeding bad?
When two merle-patterned dogs are bred together, each puppy in the litter has a 25% chance of inheriting that gene from both parents. The resulting offspring is referred to as a double, or homozygous merle. … Due to the decreased pigment on the skin, double merles are at a high risk for hearing and sight impairments.
