Rabbits dont respond well to dicipline. You might teach your bun that he cant chew on particular items when you are present, but he’d still chew them when you’re not there. I dont think screaming or yelling would help. Yelling will more likely cause him to avoid you. Its a lot better for your relationship that he doesnt see you as hostile or scary.

With buns you need to remove or block off access to stuff that the bun shouldnt get into. You can also try to redirect his agtention to stuff that je is actually allowed to chew. Young rabbits are a lot more prone to destructive behavior (aka bunstruction), so it’s great if you can  provide your bun with stuff thats ok for him to chew- like cardboard houses and twigs from f ex apple trees or willow.  Blankets that he can dig in are often appreciated.

I agree, rabbits do not respond to negative reinforcement. All it will do is harm your relationship with your bunny. Some bunnies just react differently to things as well, just like humans and other animals. Some of my bunnies are really startled by slight noises, and the other ones don’t react at all. I think it’s just natural personality variation.

You need to improve your bunny proofing (and his housing), and redirect him to safe things to chew. You might also incorporate some positive reinforcement training, and instead of telling him what not to do, you can use an “interrupter” cue, and then a command to do something else. Clicker training works really well for bunnies. For example, if you bun is getting into trouble, you can train him to come to you on command and “target”. I use this technique a lot with my trouble-maker bun Cooper. He comes running when he hears a kissy noise (usually I make this noise when I give a treat), so often I will call him to me to distract him from what he’s doing, rather than going over and trying to shoo him away from the problem.

What is the main thing he tries to chew? maybe we can give some suggestions for alternatives? I use NIC metal grid panels in my rabbit’s pens because they are chew-proof, so many you can just swap out the plastic panels with metal grids?

Rabbits can learn what “no” means, but I agree that it just teaches them not to do whatever it is while you are present. It won’t really prevent them from engaging in the unwanted behavior when you’re not around. Bunny-proofing, redirection and clicker training may prove more effective.

As a side note – Perhaps you should reconsider what his enclosure is made of. Something chew proof would probably be better.
