Anyone keep dogs and rabbits together in a small space (say... a two bedroom flat?)

I've been turning over the idea of getting a dog for some time now. I probably wont be getting one for a good few months yet anyway, but it never hurts to research early. It would be my first dog, and definitely a small breed - currently I'm leaning towards a bichon frise, since there's a good breed rescue in the area - but I'm just wondering what people's experiances are of keeping house bunnies and dogs in small places. My older two rabbits are used to dogs, since the rescue they came from was also a petshop that had people bringing their dogs in and out all the time - but my younger ones have never been in contact with a dog in their lives; and my older ones haven't seen any dogs since I moved out of my mum's place five months ago. How did your rabbits react at seeing a dog around? What did you do to help them adjust? How did you make sure the dog never bothered the rabbits (aside from taking the obvious step of never leaving the dog and the rabbits alone together)?
