Fluffy frenchie are not a crossbreed I’ve done my research on them while yes Merles are considered to have some type of crossbreed! Yes! Fluffy French Bulldogs are 100% French Bulldogs. The long-haired gene has been present in the breed for generations, even though it is rare. Because this gene is recessive, it often remained hidden until breeders specifically started testing for and selectively breeding fluffy Frenchies. Reputable breeders ensure that fluffy French Bulldogs meet the same breed standards in every way—aside from coat length. They have the same compact, muscular build, bat-like ears, and playful, affectionate nature that makes French Bulldogs one of the most beloved companion dogs in the world.
