deogees mum since I was 8 I have owned rabbits and dogs. My first dog Cindy, who is still alive, is a beagle/Kelpie x and I trust her totally with my rabbits!!! She cuddles with them, when she was younger, and I was a lot younger (and not as wise on rabbits) we used to let her chase the rabbits around the back yard until they tired and they would stop dead and she would just stand there. Supringisly none of those rabbits died of a heart attack!
I'd never allow it again!!!
Then I had a cattle dog/pit pitbull who thought the rabbits were just like a moving stuffed toy. He accidently killed one when the rabbit escaped his run and after that I made it my responsibility to get him to accpet them. I would just lock me, the dog, and a rabbit in a room. Not too many things in the room for the rabbit to hide in but a couple of things so it could feel safe. I didn't want the rabbit under the lounge for an hour while I was trying to train the dog! I would just hold him there and reward for him for every second he was settled and we did this every day, slowly building times. Then I attached a lead to him so he could get closer but I could pull him back if necessary. After one month he used to let the rabbits bite his ankles, jump all over him etc. inside....outside they were fair game!!
I now have a pure bred staffy....she is pretty good with the rabbits. I don't leave her unsupervised with them cause she trys to play and if she ever lands on one then she'll kill them with her weight. However she is getting heaps better and will now whine and yelp but will stay still cause she knows she isn't allowed to play with them. I can trust her enough to leave the rabbit room door open and she will sit at the door and make sure they don't get out but she won't go in and her bed is in that room too!
So with time and persistance you can get them to live together peacefully, just don't ever have an afternoon nap with them all running around the house together!
