How to Safely Trim Your Dog's Dew Claws

Most nail-day advice covers the four obvious nails on each paw, but there's a fifth one, higher up the leg, that owners forget about until it hooks, snags, or curls into the skin. Learning how to trim dog dew claws safely matters precisely because these nails never touch the ground: they get no natural wear, so they grow unchecked, often curling in a full circle back toward the leg. The good news is that once you know where the dew claw sits, how to read its quick, and how to steady a wiggly leg, trimming it is no harder than any other nail — and it takes about ten seconds per paw.

This guide covers what dew claws are and why they matter, a safe step-by-step method, how front, rear, and double dew claws differ, and what to do if one has already grown too long.

What dew claws are — and why they need trimming

The dew claw is the small, thumb-like nail set higher on the inside of your dog's leg, above the paw. Nearly every dog has them on the front legs; some have them on the back legs too, and a few breeds have double dew claws (more on that below). Because they sit up off the ground, they never make contact when your dog walks or runs — which is exactly the problem. The other nails get filed down naturally on pavement; the dew claw doesn't, so it just keeps growing.

Left alone, an overgrown dew claw causes real trouble. It curls in a tight arc and can grow around until the tip presses into or even pierces the leg or paw-pad skin, which is painful and invites infection. Because it juts out to the side, it also snags easily — on carpet, bedding, crate wire, or the dog's own coat when they scratch — and a snagged dew claw can tear at the base, which bleeds a lot and hurts. Since dew claws don't click on the floor the way long ground nails do, the usual audible warning is missing, so they're easy to overlook. Make a habit of checking them every time you trim; our guide on how often to trim a dog's nails covers the schedule the rest of the nails should follow.

How to trim dog dew claws step by step

Here is the safe way to trim dog dew claws without nicking the quick or the leg:

1. Find and expose the dew claw. Feel along the inner side of the leg, an inch or two above the paw. On short-haired dogs it's obvious; on fluffy breeds you'll need to part or push back the surrounding fur — or snip a little of it away with blunt-nosed scissors — so you can clearly see the whole nail.
2. Pick the right tool. A small scissor- or plier-style clipper works, but a grinder is often easier here because the dew claw sits close to the leg and a grinder lets you take the nail down gradually without the risk of a clipper's jaws catching loose skin.
3. Steady the leg gently. Support the paw in one hand and isolate the dew claw digit with your fingers. Don't twist or over-flex the leg — hold it in a natural position so your dog stays relaxed.
4. Take small amounts and watch the quick. On light-colored nails, stop short of the pink quick you can see inside. On dark dew claws you can't see it, so shave thin slivers and read the cut surface, stopping the instant a small chalky-then-grey-black "bullseye" dot appears — the same method in our how to cut black dog nails walkthrough.
5. Round the edge and reward. A quick pass with a grinder smooths the tip so it won't snag, and a treat right after keeps the whole experience positive.

If you're using a grinder, keep it on each nail for only about two seconds at a time to avoid friction heat, then come back for another pass if you need one. Keep styptic powder or cornstarch within reach in case you nick the quick.

Front vs. rear (and double) dew claws

Not all dew claws are built the same, and it changes how you handle them. Front dew claws are firmly attached by bone and ligament, so they sit stable against the leg and you can trim them just like a regular nail. Rear dew claws, when a dog has them, are frequently attached by skin alone and tend to flop loosely to the side — that makes them a little harder to hold steady and, because they wobble, more prone to snagging and tearing, so they're worth keeping especially short.

Some breeds — Great Pyrenees, Briards, and Beaucerons among them — are born with double dew claws on the back legs, meaning two nails close together. Trim each one individually, taking care around the extra skin webbing between them. Whatever the type, remember that trimming a dew claw and removing one are completely different things: removal is a surgical procedure for a vet to decide on and perform, never something to attempt at home.

What to do about an overgrown or curling dew claw

Because they're so easy to miss, dew claws are often the first nail to become badly overgrown. If your dog's dew claw has curled into a near-circle but hasn't yet reached the skin, don't try to cut it back to a normal length in one snip — the quick has grown out along with the nail, and a big cut will slice straight into it. Instead, take small amounts off the tip and repeat every few days, letting the quick recede over a couple of weeks. The full technique for this is in our guide on how to trim overgrown dog nails.

There are times to hand this to a professional. If the dew claw has already grown into the pad or leg skin, or the area around it looks red, swollen, or smells off, see your vet — that's a wound and possible infection, not just a long nail. The same goes for a dew claw that's cracked or partly torn. When in doubt, a quick call to the clinic will tell you whether to come in.

Keeping dew-claw trims calm and pain-free

Dew claws test a dog's patience more than the regular nails, because reaching them means holding the leg in a slightly awkward position and, on fluffy dogs, working right in the middle of a patch of leg fur. That fur is also the reason a grinder can hair-wrap here: loose hair winds onto an exposed spinning bit and gives a sharp, unexpected yank, which is a fast way to teach a dog to hate the whole routine.

Both problems point to the same fix — a calm, fur-safe tool. A low-vibration, fur-safe grinder like the Pawzaw grinder recesses the diamond bit behind a guarded head, so the leg fur around a dew claw can't wrap onto it, and it dampens the buzz your dog feels through the nail — the sensation, not the noise, is what usually spooks them. Pair that with the calm-handling habits in our guide for a dog scared of nail trimming: trim after a walk when your dog is tired, work on a non-slip surface, go one nail at a time, and always stop while your dog is still relaxed.

Dew claws are small, but they're the nail most likely to cause a painful problem if ignored. Check them at every trim, take a little off often so the quick stays receded, and reach for a tool that keeps the session calm.
