Go to clickertraining.com by Karen Prior. She has a section dedicated to rabbits. She is the Mother of Clicker Training. I discovered her when I began my career of animal training in the 90's. Her videos are great. She is on facebook too.
The best tip that I can give you is watch your timing. It took me longer with my rabbit than any of the other species I have tried because of the visibilty of the rabbit to the treat. I ended up clicking the exact same time as she grab the treat from my hand when introducing it to her. Where as for more visible species I would put treats on the floor and click as soon as they found the treat which may work for you if your rabbit goes for treats like this ont he floor. You know they understand the clicker when you click and they stop what they are doing to focus on the clicker.
The clicker is very exciting to the rabbit. She is beside herself offering me all her behaviors until she calms down. You will be able to stop using the clicker once theyknow the behavior and you can give it a verbal command if you want. Once clicker trained it is the best way to introduce new behaviors. The cool thing is the rabbit thinks it is training you to click!
I used the clicker training for sit, up, kiss, pet, walking on a leash, and the best for litter box training. I really want to do jumping but I have not attempted it yet because I do not trust the big bundle of trouble to jump in the right places. I watch her stare at the counters and tables thinking about it. I am talking myself into it now by discussing it.
When she is getting into to much trouble I distract her with clicker training and it seems to work because I think she gets bored and needs something new to do.
Have fun with it and feel free to ask me anything to assit you in your training.
