If the nail is white u can see the quick, if not I usually put the clipper on the nail and take a little off at a time. I clip their nails once a week and they are real short. I'm planning on getting a dremel (little hand held one) tool for doing their nails. They work like a charm.
Just do a little at a time and u will know how short u can go, and always keep a steptic pen on hand. I just got the ones in the razor isle for shaving looks like a crayon and it works great (I have never clipped my dogs) its good to have on hand just in case. I usually put the black nail threw the clipper (giloteen one sp) and put the handle against the pad and clip, this way I have never clipped a quick yet. Hope that made sense.
ttfn :)
