Nipping is how rabbit’s communicate. You can imagine that the concept of humans having clothes of different textures, thickness, and tightness can be confusing, in addition to our skin. Just like how puppies need to learn the proper intensity of a communication “nip”, so do rabbits, especially to something as foreign as a human body, clothed or not. It’s a mixed bag of things you can do, but at the end of the day, you want to make sure you’re not reinforcing the harder nips as ways to communicate. So if your rabbit is asking you to move and you do so after a harder nip, that’s reinforcing. If your rabbit is requesting food and you give in after a series of nips, that’s reinforcing.

My second rabbit was a very big nipper, and she still is, though it’s drastically reduced and it’s very small nips now. I would use the back of my hand to guide her head away (key note here– guide. Not like I’m slapping her. Literally just slowly using my hand to move her head away from my legs) when she’d get nippy until she’d just go away. I would also just walk away and not acknowledge her, to show her that this is not how you communicate. You can also yelp to try and signal that it is hurting you (even if it’s not).

I’ve had good luck with “squealing”. If you do this when they nip, it teaches them to adjust the pressure they use. A nip meant to communicate something should literally just be them placing their teeth on you.

Yup, it does sound like sexual frustration. Buns can bite down pretty hard when they mount another bun, so hard that it breaks the skin of the mounted bun. It’s not about aggression or trying to cause hurt.

Since sex drive in a young intact bun is very strong, especially this time of year, removing him from your body parts may be the best option. He could however become obsessed and refuse to leave you alone.

(I had a rabbit who became obsessed with my dog. He didn’t try to outright mount her, but he circled her, nipped her hard and sprayed pee on her, and he was relentless in his pursuit of her. I decided to have him neutered, which fully resolved the issue.)

That nipping is the precursor to mounting (he loooooves you :p ). All the unneutered buns I’ve been around are crazy nippers! It should get a lot better once he’s neutered. I agree that the squealing tip works very well in the meantime.

Yes, that squealing tip is very good! There are more tips about rabbit body language on this site: http://language.rabbitspeak.com On that site they advice to do the same an offended rabbit would do: squeal, turn your back to him a little and look over your shoulder. That says: I’m upset, but you can still make it up! Present your hand for licks when your rabbit comes to you to investigate, and let him make up again.
