Using a leash or harness on a bunny is a highly debated subject amongst long-time bunny owners and experts for good reason. There have been many accidental deaths as a result.
You see, because rabbits are prey animals, they feel very confined and trapped when on a leash. If they become scaredwhich is very easy with all the new sounds and sights outsidethey can easily break their necks, their backs or be frightened to death.
You never know when a dog might walk around the corner, scaring your rabbit and causing her to bolt.
Leashes that go around the neck are particularly dangerous as they can suffocate your bunny if she pulls too hard!
You'll also want to consider the other dangers of taking your bunny for a walk... bunnies can contract diseases from other animals, and you never know what they're going to sniff or get into when they're outside. You also have to be careful of pesticides, which can kill your bunny!
If you DO decide to use a leash or a harness, you should remember that walking a bunny is nothing like walking a dog. Bunnies generally don't like to be followed, so being behind her when you walk might make her nervous. If she gets too scared, be sure to take her inside right away.
