Turn the
QuickFinder on, insert your pet's claw, and watch
the sensor lights--they'll blink red (do not clip),
(yellow) caution, and green (safe to clip) to let
you know where to clip. This allows you to clip the
sharp tip off the nail without cutting into the
quick. The quick is the part inside the nail where
the blood vessels and nerve endings are located. If
you clip the quick, the nail will bleed.
