The Merle French Bulldog
A speckled, marbled pattern produced by the dominant M allele. Ethical breeding required.
What is a Merle French Bulldog?
The merle allele is not native to the French Bulldog — it was introduced via crossbreeding at some point in the last few decades. Because it is dominant, breeders can produce merle puppies from a single-merle parent.
Random patches of diluted pigment across a solid base, producing a mottled or "marbled" appearance. Eye color can be split or blue.
The DNA behind the color
Merle is a dominant allele — a single copy produces the pattern. Two copies (M/M) is called "double merle" and causes severe health issues.
One parent must carry a single M allele. The non-merle parent should be m/m (non-merle) to avoid producing M/M puppies.
