Dog Dewclaw Problems: Overgrown, Torn and Easy to Miss
Lillian Ruff Pet Spa
Almost every dog has a nail that never touches the ground. It sits up the inside of the front leg, an inch or so above the paw, and because it never scuffs on a sidewalk it never wears down. Left alone long enough, it keeps growing in a circle until the point comes back around and meets the leg.
It is the single most commonly missed nail on a dog, and the one we most often find already curled when a dog comes in for a bath. Owners are rarely being careless. The dewclaw is easy to miss because it hides under leg feathering, because it does not click on the kitchen floor like the other nails do, and because a lot of people do not know it is there.
Feel up the inside of each front leg, just above the paw. If you find a nail, look at the tip. If it is starting to hook back toward the skin, it needs trimming — and it will need trimming again in about a month, because nothing out there is going to wear it down for you.
Where dewclaws sit, and why some dogs have rear ones
Front dewclaws sit higher up the leg than the four weight-bearing nails, on the inner side, roughly where a thumb would be. They are attached with bone and tendon in most dogs, and plenty of dogs use them — you can watch a dog grip a chew or steady itself on a turn and see the dewclaw engage.
Rear dewclaws are a different story. Many dogs have none at all. Some breeds carry them as a normal part of the breed, occasionally doubled, and in those dogs they are often attached by skin alone rather than bone, which means they flop, sit loose, and snag more readily. Some dogs have had front or rear dewclaws removed as puppies, so you may look and find nothing. All of that is normal.
The reason they get skipped at home is simple mechanics. When you hold a paw and clip, you are working with four nails lined up in front of you. The dewclaw is behind your hand, higher up, often buried in coat. On a fluffy dog you may need to part the hair to see it at all. If nobody has ever pointed it out to you, you will clip four nails, feel finished, and put the paw down.
It never touches the ground, so it never wears down
Dog nails have two things acting on them: growth from the nail bed, and wear from contact. On the four main nails those two roughly balance out, especially for a dog that walks on pavement — the sidewalks along Larkfield Road file nails down more than a lawn ever will. The dewclaw sits above all of that. It gets pure growth and no wear.
Which is why a dewclaw problem is almost always a slow one. It is not an accident. It is six or eight months of a nail growing unchecked, curving as it goes, until the tip is pointing back at the leg it came from. On dogs with heavy leg feathering, the whole thing can be invisible until it is already a problem.
Nothing is filing that nail down. If you are not trimming it, nobody is.
Some dogs are more exposed than others. A senior who walks less than she used to. A dog recovering from surgery. A dog who does most of his exercise on grass and dirt rather than pavement. Small dogs generally, because they simply put less force through the foot. In all of those cases the four main nails also grow long faster than the owner expects — the dewclaw just gets there first.
What an overgrown or snagged dewclaw looks like
Fine for now
- Tip is short and points away from the leg
- Nail sits flat against the leg, no arc
- Dog lets you touch and move it without reacting
- Skin underneath looks the same as the skin around it
Book a trim
- The nail has started to hook, even slightly
- You have to lift hair to find it, and cannot remember the last time it was cut
- It catches on bedding, blankets or a carpet
- It snags your sleeve when you pick the dog up
- Rear dewclaw that moves loosely and hangs
The other tell is behavior. Dogs who lick one specific spot on a leg, chew at one wrist, or flinch when that leg gets handled are telling you something about that area. That is not a diagnosis — plenty of things cause leg licking — but it is a good reason to actually look.
| What you notice | What it usually is | Next step |
|---|---|---|
| A curved nail up the inside of the leg | Ordinary overgrowth, no wear | Book a nail trim |
| Nail catching on fabric | Too long, hooked tip | Book a nail trim |
| A cracked or split dewclaw, dog is comfortable | Damage without an open wound | Have it looked at soon |
| Bleeding, swelling, limping, or nail pulled from the bed | Injury | Call your vet, not a groomer |
When it is a vet visit, not a grooming appointment
A torn dewclaw — one that is bleeding, hanging, partly pulled away from the nail bed, or surrounded by swelling — is a veterinary problem. The quick of a nail is living tissue with blood supply, and a nail bed injury can be genuinely painful and can get infected. Groomers do not treat that. Call your vet, and go the same day if there is bleeding or your dog will not put weight on the leg.
The same goes for a nail that has grown far enough to press into or break the skin. Once the skin is broken it is a wound, and it is out of our hands. We will tell you plainly at drop-off if that is what we are looking at, and we will not proceed as though a trim solves it.
Do not pull it
A partly detached nail is still connected to living tissue. Pulling makes it worse and hurts.
Keep the dog from licking it
Even a light cover or a cone until you get advice.
Call your vet
Describe the bleeding and whether the dog is bearing weight. Let them decide the urgency.
The fix is boring: check it every time
Dewclaws are one of the few grooming problems that essentially disappear with routine. A dog whose nails are done on a regular cycle never gets a curled dewclaw, because there is never enough uninterrupted time for one to form. There is no technique to learn and no product to buy — it is just a nail that has to be on somebody's list.
If you trim at home, that is genuinely fine, and we would rather you did it well than paid us for something you can do yourself. Two honest notes. First, count five nails on each front leg, not four. Second, take small slices off a curved dewclaw rather than one confident cut — the quick follows the curve, and on a long nail it is further down than it looks.
And if what you want is only nails, with no bath and no haircut, it is worth knowing that the big chain salons in the surrounding area — there are Petco and PetSmart locations in Huntington, Huntington Station and Commack — position nail trims as a walk-in service. We work by appointment. If you need a nail done today and cannot get a slot, that is a reasonable option and we will say so.
Most of the walking around here is pavement and park path — Larkfield Road sidewalks, the on-leash paths at Northport Village Park down at the foot of Main Street, the Town of Huntington off-leash run at the animal shelter on Deposit Road. Every one of those wears the four ground nails a little. None of them touch the dewclaw. It is also worth handling the whole foot and lower leg regularly for another reason: Suffolk County has real tick pressure, and in 2025 county surveillance found 26.6% of nymph-stage deer ticks carrying the bacterium that causes Lyme. Checking a dewclaw and checking for ticks are the same thirty seconds.
Questions people actually ask
How often do dewclaws need trimming?
There is no universal number, because it depends on how fast your individual dog's nails grow. A practical approach is to look once a month and trim whenever the tip has started to curve. Most dogs settle into a rhythm somewhere around every four to six weeks, and if your dog is on a regular grooming schedule it usually takes care of itself.
My dog does not seem to have dewclaws at all. Is that a problem?
No. Some dogs are born without them, particularly on the rear legs, and in many dogs the front ones were removed in the first days of life. If you have felt carefully up the inside of both front legs and found nothing, there is nothing to trim. Ask us to double-check at your next appointment if you want certainty.
The dewclaw has curled around and is touching the skin, but there is no blood. What now?
Get it trimmed rather than waiting. A nail at that stage is usually still straightforward to cut back, though it may need to be shortened in stages over a couple of appointments because the quick has grown out with the nail. If it has already broken the skin, see your vet first.
Can you trim just the nails, without a bath or groom?
Ask when you book — say what you need and we will tell you honestly what fits. Bear in mind East Northport is a grooming salon working by appointment, Tuesday to Saturday, so we cannot promise anything same-day.
My dog panics when I touch his feet. Can he still be done?
Often yes, but tell us before you arrive rather than at the table. Foot-sensitive dogs do far better with a groomer who is expecting it and can take the legs one at a time, and we would rather stop early and finish another day than turn a nail trim into something your dog dreads. If the reaction is severe, your vet may be the better first call.
Does having the dewclaw removed later solve it?
That is a surgical decision and only your vet can advise on it. It is not something to decide based on a grooming article, and for most dogs regular trimming makes the question moot.
