I think 'dwarf' in dwarf lopped means that the ears are small not the actual rabbit because I had a French Dwarf Lop and she was HUGE! An English Lopped Rabbit has ears that brush across the floor...
Ears help rabbits to hear, of course! (But if it is arctic hare, even though it may hear better, it does not keep warmth inside.) Rabbits also use their ears to communicate with. They can move them...
you know that your rabbit is good for you when it starts licking you and warming up to and following you around the house when you let it out for a run all rabbits are good if their owners handle...
Yes they can. And male rabbits are very dominent. I had 2 lop rabbits 1 younger than the other, and the older rabbit beat up the younger one and he died. :(
