At our rabbit sanctuary we hear stories ALL the time about dogs and bunnies getting along....it really does come down to the dog's personality.

We get a lot of heartbreaking stories where a dog has accidently killed a bunny while trying to play with it. Then there are the stories where the dog's natural herding/hunting instinct just "suddenly" kicks in after years of the two living peacefully together and the rabbit dies. As Karen said, it only takes a heartbeat and you can be right there and right on top of both animals and still be unable to prevent the death/injury of the rabbit.

My advice is two-fold....... NEVER leave them alone together, esp at first,as they are getting to know each other. The other is to get a puppy pen or cage and put the rabbit in there and let them get to know each other through the fencing.

Good luck. It is nice of you to save the bunny, you are to be congratulated.
