I've had some wonderful ND. I've also had some hop up to my arm, look at it, and then promptly punched 3 sets of holes in it. One I put my hand in front of (with plenty of space) to turn him from falling off the furniture and he just latched on. Managed to fit the length of my hand under the base of my thumb in his mouth and sink 2 grooves down. Another went over a lifted food dish to get to my hand. I had blood pour out of me more with ND than checkereds and I couldn't hit space bar with my right thumb for a week. Like I said though I had some great ND. Not just bucks. We had a doe we were going to train for a therapy animal but she is the only rabbit I've lost to pasteurella and she wasn't exposed to anything but guinea pigs from a show because she was a house pet. Hezaa was a bit less outgoing but would calmly sit with you, burrow under blankets, and produced litters of around 5 regularly with no trouble. Kido the buck liked to have a rug or towel in front of his door to lay on and we left his cage door open 24/7. He just rarely bothered to leave. I'd always see him sitting there with his little front feet tucked in. He was wonderful with the does and I sometimes used him to breed sensitive first time does of other breeds if they were freaking out too much with their bucks. I kept his grandson that was also son as a pet since he was too big to be useful for breeding. It's hit or miss with these guys because some people care to breed for temperament and some will breed anything that does the best on the show table.
