Can floppy eared rabbit live outside in the winter?

It depends on the climate where you live. Pet rabbits are descended from wild European rabbits, and they can't handle very hot or cold temperatures. If it stays between 10-23 degrees Celsius where you live (50-75F), that is fine for your rabbit.

There are other dangers outside, not just bad weather. Parasites, insects, poisonous plants, predators, and so on.
