How to Trim Black Dog Nails

Why black nails are harder

Every dog nail has a quick, a living core with blood vessels and nerves. On white or clear nails it shows as a pink area, so you can see where to stop. On black or dark nails, the pigment hides it completely, so you cannot judge the safe length by looking at the outside. That is why many owners are nervous about dark nails and why the method has to change.

The answer is to trim from the outside in, a tiny amount at a time, with either dog nail clippers or a nail grinder, and let the inside of the nail tell you when to stop. VCA Animal Hospitals advises removing only a very small amount per cut on dark nails, roughly a sixteenth of an inch or less, and watching your dog's reaction.

Step-by-step: trimming dark nails

Step 1: Hold the paw firmly, press gently on the pad to extend the nail, and move fur aside. Step 2: Start at the very tip, below where the nail curves, and clip a thin sliver straight across. Step 3: Look at the cut end. Near the tip you will see dry, crumbly, grayish-white nail. Step 4: Clip another thin sliver and look again.

Step 5: As you get closer, the AKC describes a chalky white ring appearing around a slightly darker center. Then a small dark or black dot appears in the middle, which looks moister. That dot is the front of the quick. Stop as soon as you see it. If you are unsure, stop a cut early; you can always take more next week.

Tricks that make it easier

A nail grinder lets you remove material gradually and see the surface change, which many owners find easier on dark nails than clippers. The AKC suggests grinding across the bottom of the nail and then smoothing from the tip, supporting the toe firmly. Keep long fur away from the spinning drum. Turn it on near your dog with treats for a few days first, so the noise and vibration are familiar.

Look at the nail from underneath. On many dogs you can see where the solid nail ends and a hollow, curved tip begins; that hollow part is safe to trim. Good light helps. Some owners shine a small flashlight behind a lighter-colored dark nail, though on truly black nails it rarely shows the quick. Compare with any light nails your dog has, which give a rough guide to quick length on its other toes.

If you nick the quick

You may see a drop of blood or your dog may pull away. Press styptic powder onto the nail tip firmly for a minute or so; cornstarch or flour works if that is all you have. Stay calm and give a treat. Most bleeding stops within a few minutes. Take a break before carrying on, or finish another day.

Call your vet if bleeding continues after several minutes of firm pressure, if the nail is split, or if your dog limps, licks the toe constantly, or the toe swells over the next few days. Those can be signs of infection or injury that need treatment.

Keeping the quick short

When nails are allowed to grow long, the quick grows with them, so a long-nailed dog cannot be trimmed short in one go. Trimming a little every one to two weeks, with dog nail clippers or a grinder, encourages the quick to recede, so you can gradually get the nails to a good length where they no longer touch the floor when your dog stands.

If your dog's nails are very overgrown, or it is too anxious to handle, ask your vet or a groomer to do the first trim. Ask them to show you where they stop on your own dog's nails; a single demonstration takes much of the guesswork out of dark nails.
