!st--neuter. 2nd-- treat him as an alpha rabbit would--pin him down when he doesn't co-operate, roll him on his back and keep him there, then speak to him in a harsh voice to emulate how an alpha would angrily grunt at an offending subordinate. Three of our "rescues" were from shelters that were ready to euthanize them as they were biters too. We still have one with us and he's a real sweety now, not the bitey little crab he used to be--wants attention now where he did not want it before. The other 2 have passed to the bridge after a long time with us, and, they were both really good bunnies. Just did not want to adopt them out to anyone as I was afraid they might backslide--had one that was really one of my best and smartest, but he behaved perfect for me but not for the girl that wanted to take him--the good thing is that I had a really sweet female lop that worked out perfect for her and her family. Not always a medical issue--read up on rabbit behaviors--they are different from cats, dogs and most other animals so you need to learn--same with fish, birds, reptiles, spiders, etc. Didn't think about it til just now, but we have more than 40 books relating to various animal companions we've shared our home with over the years.
