no its defiantly not the best way to train them. A rabbit that is well handled and socialised from birth usually doesn't display nipping (assuming by nipping we're talking about the little nips not the break the skin kind of bites).

It is usually used to get attention (rabbits nip each other for grooming or when ignored, but obviously through a thick coat of fur its more of a nudge than it feels on our skin). The best solution is to give the rabbit no attention at all after a nip (they usually come when you stop grooming/interacting with your bunny) and to work out what triggers them and to avoid it. Then interact with your bunny offering it attention/treats when its behaving, when it nips move away so it doesn't learn to associate nipping with getting what it wants. (Obviously if its biting as a fear/aggression issue that is dealt with differently)

A rabbit with a companion is much less likely to nip as it will have the constant attention from its bunny friend and wont need to keep demanding it from people.

 

Rolo constantly nips me or chews on my clothes, he only ever does this when he running around me and I try to stroke him, iv always presumed iv given him to much attention and he want me to "just go away so he can do his own thing"? X
