By: GSD LoverI bought these to trim my German Shepherds\' nails. Both dogs have black nails. This product claims to work on black nails, but it doesn\'t. I watched the DVD to make sure I was using them properly. The light always stayed red from base to tip. I went back to my old style guillotine clippers, and clipped the same nail with no bleeding. What a waste!
