...and do you use a dremel or clip them?

My dogs get theirs done every 2 weeks on average, sometimes every week. I can't stand hearing their nails clicking on the ground constantly so they get them as short as possible and they never, ever touch the ground. They get them done with a dremel and much prefer it to getting them cut all the time, Tango puts up a fight with the dremel but was 100 times worse with the clipper.
