Trimmed Nails

Dogs with light fur/skin typically have slightly transparent nails. You should be able to see the pink quick from the side as shown in the tables above and below. Top nail is wet with water to remove chalky texture and show structure.

Dark Trimmed Nails

Black nails are typically more difficult as you cannot see the quick from the outside. Look at the size of the chalky layer while trimming. As you get closer to the quick, this layer will grow as seen in the diagram to the left.
