It sounds like hes doing it because shes not accepting him as the dominant one (not grooming him, and semi ignoring him). He doesnt like that, so it makes him mad in which he starts the fur pulling. You might not want to keep them in the same cage together to avoid further damage for a while. Then restart the bonding process in a neutral territory. But do note, not all rabbits will get along. Its possible that they just dont “click”

What type of stress bonding techniques have you done? I was in the same position as you about a month ago, and the washer and dryer technique was what really put me over the major hurdle to completing the bond between my male and female.

I’m also in a similar situation and I don’t know what else to do! please let me know if something ends up working for you! i’m having this issue with my female. except there’s been no mounting. She just chases him and tries to pull out fur. My male does nothing at all… poor Loki 

You can try putting some mushed banana on your boys head so she will groom him. If he feels he’s established as the dominant bun, hopefully, he will let up.

I have a resident female bun who is a house rabbit. I was worried that she was lonely as I have been traveling more for work and my husband isn’t really a bunny person. so I found a male for her to try from the local adoption agency. Both are desexed and around 3 years old. I have only been trying to bond them for 4 days, but am ready to give up. They both will not submit in their struggle to be the dominant bun, and I’ve had to resort to putting something between them to stop them from fighting. I have their bonding sessions of 20 min in a pen (neutral territory). He will groom and eat in her prescence, but she is uninterested in food when in the pen. She has groomed herself in front of him, and he had groomed her the first two ‘dates’ but appears to have given up. Advice please? I have never attempted a bonding before.

i’ve been bonding my two rabbits for 2 months about, and I still question whether they’re fully bonded or not. I wouldn’t trust my female alone with my male. My buns were really awful at first. (mainly because of my female.) She was clearly dominate and my male just wasn’t willing to socialize with her at all because he was so scared. Mine were in two separate cages but next to each other and he was totally fine but in the x-pen, he would not dare touch any food around her, but she would eat freely as she pleased. I was about to give up until I put my foot down, and did stress bonds every single day- I would try the pen after, and if my female tried to fight- it was right back to the stress bonding. I would put them in a laundry basket and walk around… drag them around in the basket.. put them in the bathtub.. and do car rides. Car rides is what ended up helping me with these two. I would actually tilt the carrier up, so they were forced to sit right next to each other. I also tried the banana trick on their heads to get them to groom each other. My male was very scared to attempt to get the banana off my female. He still to this day will not groom her. He just demands her to groom him- which usually she will do, even though she is clearly the dominant one. So I highly recommend stress bonding. It’s not fun, and you’ll most likely feel bad in the process.. but it seems to work for a lot of people, including myself. My female still goes after my male and tries to pull hair from his butt.. I’m hoping in time it’ll stop but I still won’t be leaving them alone or putting them in a cage together as their home. Just try and be patient and stick to whatever works for you. it’ll all work out. 

Thank you very much for the advice. I had thought of trying it, but it was a frowned upon (by the adoption agency). I had come to the conclusion that I have nothing to lose by giving it a try, and a lot of bunny bonding advice is just what you have given.
