Before you even begin practicing the trick, make sure the rabbit knows that his home is a place where he can feel safe. Some house bunnies love playing and having free reign so much that they dread going back home. That's how my house bunny used to be. The rabbit doesn't have to look forward to going home, but he shouldn't treat it like it's a life-or-death situation every time playtime is over.
There are a couple things you can say to get the rabbit to do the trick. You can use the phrase "Go Home", which is my personal favorite, "Bedtime", if the rabbit is to be shut up at night, or pretty much whatever you want, as long as you stick to it and say the same thing every time.
For this trick, plan the time accordingly. If the rabbit is tuckered out from hours of playtime, he will be more cooperative. Do the trick when it's actually time for the rabbit to go home, not when he's usually playing. My rabbit gets out of her cage twice a day - in the morning, around 9:30 AM and at night before I go to bed. During these times, she's hungry and ready for breakfast/dinner, which it made it easier to teach her. When she's more hungry, she's more willing to get an edible reward. Never withhold food as punishment - just withhold the treat when he or she doesn't preform the trick correctly.
My rabbit gets oats on top of her food when she does the trick. She knows that's what she gets when she does it right, so she cooperates nearly every time now.
To actually teach the trick, once your rabbit is tuckered out and it's time for it to go home, pick up the rabbit and put it at the door of its home. Snap inside the cage or behind it and say "Go Home!" or whatever you choose to say. You just do the snap, or just say "Go Home." Both seem to work better for me. After you have finished saying the phrase and snapping, put the rabbit in its home. Praise it, and offer it oats (or whatever treat you have selected), for a job well done. Practice it AT LEAST once daily, but twice is more sufficient.
Over the next couple days the rabbit will realize that it gets a treat when it goes home. For the first couple times, do it like I said above. In the subsequent tries, only give the oats or treat if it goes home by itself when you snap. If it doesn't, start from the beginning and keep practicing.
Your rabbit will learn the trick very quickly. You will start to notice improvement in just a short week of doing it every day. Don't forget to keep practicing even if the r. abbit knows the trick
You may have to change the above guidelines and morph them to fit your setup and needs. This way does not work for everyone. This trick is mostly for the house rabbit, though an outside rabbit could learn it just as easily if you practice often enough.
