Miniature or dwarf rabbits are rabbit breeds characterized by weight under 4 to 5 pounds, often caused by a dwarfing gene. There are up to 10 recognized breeds of miniature or dwarf rabbits recognized by the American Rabbit Breeders Association and the British Rabbit Council.
Most dwarf rabbits are closely related to Netherland Dwarf rabbits, which are the smallest and most popular dwarf breed and weigh 2 to 2.5 pounds. Breeds with the same dwarfing gene as Netherland Dwarfs include American fuzzy lops, dwarf hotots, Holland lops, Jersey woolys, lionheads, and black and browns. Miniature breeds without the dwarfing gene include Polish and Britannia petites. The British Rabbit Council also recognizes miniature lion lops and miniature Cashmere lops.
