I think whether or not you have a dog and bunnies together depends on the owner. We get many bunnies in to our sanctuary that have been injured by "nice" dogs. So who do they give up? The bunny of course. We are told many stories of bunnies who have been killed by "nice" dogs because the owner's attention wandered from supervising the two together or the dog suddenly turned on the bunny before the owner could stop it. Not all dogs kill bunnies but many do.

So I guess I'd say its on your conscieous and your risk to take. I just feel sorry for the rabbit.
