My way may be a little strange, but, its the only way that I can get either of my buns to sit still for it. Ive tried trimming as well, never got to shaving. Both of mine are dwarfs and have really fine fur so the brushes never really do help. I actually get a lint roll (buy the cheap ones. what you get is what you pay for. Cheaper always seem less sticky, which, is good for a delicate bunny!). Ill sit them on my lap, gently rub it across their fur (I’m assuming they think I’m just petting them) and seems to help a lot with the shedding. My little hyper buns are actually pretty calm when I do this. I usually use 2 sheets, do it once a day for 2 or 3 days right as its getting to that time of year, and it usually keeps them pretty clean from flying fur for a few weeks! I may end up doing it two or three times during the end of spring, all summer, and early fall months, but its definitely worth it and they don’t seem to mind it.
