If your dog breaks a nail or dewclaw, keep them calm, apply gentle pressure with clean gauze and a styptic or clotting powder to stop the bleeding, and call your vet. A vet visit is especially important when the quick is exposed, the nail is split to the base, bleeding will not stop or your dog is in significant pain. This guide is general information, not a replacement for veterinary care.
Signs your dog has a broken nail
- Sudden limping or holding a paw up
- Licking or chewing one toe
- Blood on the floor or bedding
- A nail that hangs at an angle, is split or shows pink tissue
First-aid steps at home
- Stay safe: even gentle dogs can snap when in pain. Ask someone to hold your dog calmly; use a muzzle if needed.
- Stop the bleeding: press clean gauze on the nail. Apply styptic powder, or cornflour or baking powder if that is all you have.
- Protect the paw: a light, non-stick dressing can help on the way to the vet. Never wrap tightly: it can cut off circulation.
- Stop licking: use a cone if your dog keeps going at the paw.
- Do not pull on a nail that is still firmly attached.
Veterinary sources also advise against using hydrogen peroxide on the nail bed; ask your vet for a suitable antiseptic.
When to see the vet
Call promptly if the quick is exposed, bleeding lasts more than a few minutes, the nail is split up to the toe, your dog is in a lot of pain, or you notice swelling, odour or discharge later. The vet may remove the damaged piece under sedation and prescribe pain relief or antibiotics.
Why dewclaws break so often
The dewclaw sits higher on the leg and does not touch the ground, so it is not worn down by walking. It grows long, curves and catches on carpets, grass and blankets. Check dewclaws at every nail session. Our guide on back nails and dewclaws explains how to include them in your routine.
How to prevent broken nails
- Keep nails short enough that they do not touch the floor (see how long nails should be).
- Check dewclaws and back nails monthly.
- Maintain front nails between trims with short rewarded sessions on a scratch board such as PlayToTrim.
- Look at paws after hikes or rough play.
Frequently asked questions
Can a broken dewclaw heal by itself?
Minor cracks may settle, but an exposed quick is painful and can become infected. Ask your vet.
Do I need to take my dog to the vet for a broken nail?
Yes if the quick is exposed, bleeding continues, the nail is split to the base or your dog is in pain. When in doubt, call.
Will my dog's broken nail grow back?
In most cases the nail regrows from the nail bed over time, if the bed is healthy. Your vet can confirm.
What can I put on a dog's broken nail?
Styptic powder to stop bleeding, then follow your vet's advice on antiseptic and dressing.
