I use clippers from the pet store. It really is helpful to have someone assist you if possible to hold Sue. My 3 all react differently to nail clipping. Molly I hold like a baby and my husband does the cutting. Vazzle gets snippy so we put a soft muzzle on her and let her lick peanut butter off a spoon. You can start by just showing the clippers and give a treat but don't clip. That way they aren't freaked out by the clipper. Some people use those dremel things too and they work well.
