That sounds like a riddle :lol: You're right, the dwarf lop (2-2.5kg) is a dwarf of the large french lop (4kg +), which are very big, so although they are called dwarfs they are actually medium sized rabbits. The mini lop (1.5-2kg) is smallest. Of course those are breed standards so you get big minis and small dwarfs and crosses. Mini lops have proportionally shorter ears and flatter noses than a dwarf which helps with guessing.
However, watch out if you are talking to people online because in the states they called dwarfs lops mini lops and mini lops holland lops (I think that's the right way around).
