The Mini Lop is one of the younger lop breeds, with roots in mid-twentieth-century Germany. It descends from the German lop lineage, and its immediate ancestor was a small lop-eared rabbit then known in Germany as the Klein Widder, or "little lop." The breed was bred down in size from larger German lops while keeping the heavy, rounded body and the distinctive ears that hang close to the cheeks.
The breed's path to the United States is well documented in rabbit-fancy circles. American breeder Bob Herschbach encountered Klein Widder rabbits at the 1972 German national show in Essen, acquired breeding stock, and brought them home. Over the following years he and other fanciers worked to stabilize the type and develop a written standard suitable for North American shows.
The American Rabbit Breeders Association accepted the breed under the name Mini Lop in 1980. From a handful of imported animals it grew quickly into one of the most widely kept lop breeds on the continent, helped by its manageable size and easygoing nature.
A point of frequent confusion is worth flagging for anyone buying or showing across borders. In the United Kingdom and much of Europe, the rabbit Americans call the Mini Lop is registered as the Dwarf Lop, while the British "Mini Lop" is a smaller animal that Americans know as the Holland Lop. The names are effectively swapped, so pedigree paperwork should always be read against the registering body's standard rather than the label alone.
