How to Trim Your Dog’s Nails

Know Why Nail Length Matters

Overgrown nails aren’t just a cosmetic issue. When nails are too long, every step pushes them back into the nail bed, splaying the toes, straining the joints, and forcing the dog to alter how it stands and walks. Over time that leads to sore feet and poor posture. Left long enough, nails can curl round and grow into the pad.

The simple test is sound: if you can hear nails clicking on the floor when your dog walks, they’re too long. A correctly trimmed nail clears the ground when the dog stands naturally.

The aim of regular trimming is not just shortening the nail but encouraging the quick, the living core inside, to recede over time, so you can keep nails short comfortably.

Find the Quick on Light and Dark Nails

The quick is the pink, blood-and-nerve-filled core inside each nail. Cut into it and it hurts and bleeds, so your whole job is to trim close to it without touching it.

On light-coloured nails, the quick is easy to see: a pink strip running down the centre. Cut a few millimetres beyond where the pink ends. On dark nails, you can’t see it from the outside, so you go by the cut face instead. Trim small slivers, and after each one look at the freshly cut end. When you see a pale, chalky white ring, stop; when a small dark or moist dot appears in the centre, you’re at the edge of the quick and must go no further.

Good light helps enormously. Trim in bright daylight or under a lamp rather than in a dim room where you’re guessing.

Cut a Sliver at a Time

Hold the paw gently but securely and isolate one nail with your fingers. Take off a thin sliver at roughly a 45-degree angle, following the natural curve of the nail, then look at the cut end before you decide whether to take more. Small, repeated cuts are always safer than one confident big one.

If you’d rather grind than clip, especially on thick or dark nails, a rotary tool gives more control over how much you remove; the Dremel PawControl grinder takes the nail down gradually so you can stop the instant you near the quick. Whichever you use, deciding between the two comes down to your dog and your confidence, which we compare in clippers versus grinders.

Work through the paws steadily and don’t feel you must do all four in one sitting. A calm half-job beats a stressful full one.

If you cut the quick it will bleed and hurt. Press styptic powder firmly onto the tip to stop the bleeding, keep the dog calm, and stop trimming that paw. Persistent or heavy bleeding warrants a vet call.

Don't Forget the Dewclaws

Dewclaws are the extra nails higher up on the inside of the leg, usually on the front legs and sometimes the back. Because they never touch the ground, they don’t wear down naturally, so they’re the ones most likely to overgrow, curl round, and grow into the skin if you skip them.

Check for them every single session. Trim them exactly as you would any other nail, finding the quick and taking slivers, but mind the loose skin around the base, as dewclaws often sit on a little flap of skin you don’t want to catch.

Some dogs have double dewclaws or none at all, so run your hand up each leg and look. A quick check now prevents a painful ingrown nail later.

Desensitise a Nervous Dog to Nail Time

Plenty of dogs dread having their feet touched, and forcing the issue only cements the fear. Build a positive association slowly instead. Start by simply handling the paws and pairing it with a treat, for a few seconds at a time, over several days. Then introduce the clippers or grinder just to be seen and sniffed, rewarding calm.

Progress to touching a nail with the tool, then trimming a single nail, then stopping and rewarding. It’s fine if a full set takes several short sessions across a week. A dog that stays relaxed for one calm trim a day is far easier to maintain than one wrestled through all four paws.

Handling and paw care sit alongside other calm routines like cleaning ears and paws, so folding nail time into that gentle handling practice pays off across the board.
