I'd suggest following this video precisely. I've had several difficult buns. When I first watched this video, I thought "no way will this work." But I was (thankfully) wrong. Watch it over several times. Get the details...
tall table, how she pulls the rabbit in, jiggling the back foot, doing the press, press, clip thing... do it all just as she describes. It can work!
The lady in the video came up with this method when she volunteered at a rescue and had to find a way to clip those nails by herself without any help. And these were with rabbits that didn't know her.
(Treats can help with some rabbits. Mine ignored any favorite treat during nail trimming.)
Yes ! He's so happy and naughty lol x
