My Dog Broke a Nail

A broken nail is painful and can bleed a lot, but it is usually not a serious emergency. The most important things are to stop the bleeding, prevent infection, and keep your dog from licking the paw. If the nail is dangling, do not pull it off -- let your vet handle that. Here is exactly what to do.

How to Treat a Broken Nail at Home

Stay calm. Broken nails bleed a lot and your dog will be in pain, but this is manageable.
Restrain your dog gently. Even friendly dogs may snap when they are in pain. Have someone hold them or wrap them in a towel.
Stop the bleeding. Apply styptic powder (Kwik Stop) directly to the nail and hold pressure for 30 seconds. No styptic powder? Use cornstarch, flour, or even a bar of soap pressed against the nail.
Clean the area. Once bleeding stops, gently rinse the paw with clean water or a mild antiseptic solution.
Protect the paw. Wrap loosely in gauze or a clean cloth. Do not wrap too tightly -- you should be able to slip a finger under the bandage.
Prevent licking. Put an e-collar (cone) on your dog. Licking introduces bacteria and delays healing.
Do NOT pull off a dangling nail. Leave it for the vet. Pulling it can damage the nail bed and cause more pain and bleeding.

Why Broken Nails Bleed So Much

Dog nails contain a structure called the quick -- a blood vessel and nerve that runs through the center of the nail. When a nail breaks at or above the quick, it bleeds freely because the blood vessel is exposed. This is the same reason nail trims can bleed if you cut too short. The quick is more exposed in dogs with overgrown nails because it extends further as the nail grows.

Types of Nail Breaks

Cracked or chipped tip: The nail cracked at the very end, past the quick. Minimal pain and no bleeding. File it smooth to prevent catching.
Broken at the quick: The nail broke where the blood vessel is. Bleeding, pain, and the dog will likely limp. Treatable at home with styptic powder.
Hanging or dangling nail: Part of the nail is torn but still attached. Do not pull it off. Wrap the paw and see the vet.
Nail torn off completely: The entire nail has come off, exposing the raw quick. Very painful. Clean, bandage, and see the vet for pain management and possible antibiotics.

Preventing Nail Breaks

The number one cause of broken nails is overgrown nails. When nails are too long, they catch on carpets, decks, roots, and cracks in pavement. Keep nails trimmed every 2 to 4 weeks. If you can hear clicking when your dog walks on hard floors, the nails are too long.

Pay special attention to dewclaws (the "thumb" nails on the inner side of the paw). These do not touch the ground and never wear down naturally. Neglected dewclaws can grow in a circle and puncture the pad.

When to See the Vet

Most broken nails can be managed at home, but see your vet if:

Bleeding does not stop after 10 minutes of pressure and styptic powder
The nail is dangling or hanging by a thread
The entire nail has been torn off
You see swelling, redness, discharge, or a bad smell (infection)
Your dog is still limping after 24 hours
Your dog will not let you examine or treat the paw
The same nail keeps breaking (could indicate a nail bed tumor, especially in older dogs)

Frequently Asked Questions

How do I stop my dog's broken nail from bleeding?

Apply styptic powder (like Kwik Stop) directly to the bleeding nail and hold gentle pressure for 30 seconds. If you do not have styptic powder, cornstarch or flour can work as a substitute -- pack it onto the nail and hold it in place. If bleeding continues for more than 10 minutes despite pressure and styptic powder, call your vet. The quick (the blood vessel inside the nail) bleeds a lot, but it usually stops with proper treatment.

Should I pull off a dangling dog nail?

No. Do not pull off a dangling or partially broken nail yourself. This is extremely painful and can cause further damage to the quick and nail bed. A vet can properly trim the nail under sedation or local anesthesia if needed. If the nail is catching on things, you can loosely wrap the paw in gauze to protect it until your vet appointment.

Can a broken nail get infected?

Yes. When the quick (the living tissue inside the nail) is exposed, bacteria can enter and cause infection. Signs of infection include swelling, redness, warmth, discharge (pus), a bad smell, and the dog licking the paw excessively. Keep the area clean and prevent licking with an e-collar (cone). See your vet if you notice any signs of infection.

Will a broken dog nail grow back?

In most cases, yes. The nail will grow back over 2 to 3 months as long as the nail bed (the tissue the nail grows from) is not severely damaged. During regrowth, the nail may look slightly different or be a bit thicker. If the nail bed was badly damaged or infected, the nail may grow back irregularly or not at all.

How can I prevent my dog from breaking nails?

Keep nails trimmed regularly -- overgrown nails are more likely to catch and break. Trim every 2 to 4 weeks, or walk your dog on pavement regularly to naturally file them down. Use sharp, proper nail clippers or a Dremel-style grinder. Pay extra attention to dewclaws, which do not wear down on their own and can curl into the pad if neglected.
