hey there, 'Darby' didn't like getting his nails clipped either and i found the more he moved the harder it was!
I changed my clippers from one that cuts like a scissors to one that cuts like a cigar cutter thingy or a guillotine type. this made it safer to cut.
I also found that if i lay him down on his side and lift the paw closest to the ground he stays still longer.
or you could always file/grind down the nails or walk him on concrete
