The following is from the book, "Living with a House Rabbit". I encourage you to buy the whole book, it's really amazing and has a lot of great tips, advice, everything, on house rabbits. It has really helped me when I first got my house rabbit. I had so many questions and this book was great at answering them!
The likelihood of a successful canine/rabbit combination is largely determined by the personality of the dog and the degree of socialization and training. Some breeds, with a highly developed chase instinct (such as terriers and bloodhounds), may not be able to restrain themselves if the rabbit makes a sudden move. However, animal behaviorists now recognize that breed is less important than socialization, and whether or not the dog has met rabbits or cats during the critical socialization period between 3 and 12 weeks of age.
Before contemplating mixing a rabbit with a dog, you need to consider practical matters, as well as preparing a contingency plan in case the introductions don't work out. For example, in a wide-open home, you would find it difficult to separate your animals when you are unable to supervise them. Even if one of the pets were cages, the other could easily tease or terrify the caged party.
Step 1: Take the rabbit into a room with a door that closes and locks. If at all possible, keep the other pets away from the rabbit, only allowing them to smell it from behind the door.
Step 2: Allow the cat/dog to see and smell the rabbit, but provide a way for the rabbit to escape if it feels threatened. Don't allow the cat or dog to be able to touch the rabbit.
Step 3: Introduce the rabbit to a single animal family member at a time, in a small area where they can smell, see and touch each other. Supervise the entire time, and remove the rabbit immediately if any aggression or hostility is shown by either animals.
These 3 steps should take a while to get through. The actual time will depend based on your animals, how many you have, and how frightened the rabbit is of them. Each step might need to be repeated several times. It could take anywhere from a couple days to a month, or much, much longer. Definitely don't rush the process; and never force your animals to become friends. It must be their decision.
