Have someone hold your pet, or wrap them in a towel (the 'purrito' for cats). Pets feed off your energy — slow breaths, soft voice.
Press styptic powder (Kwik Stop) firmly onto the bleeding tip for 30 seconds. No styptic? Use cornstarch, flour, or rub the nail into a bar of unscented soap.
Wrap the paw in clean gauze or a clean cloth and hold pressure. Don't peek — lifting breaks the clot.
Once bleeding stops, keep your pet off carpet and out of dirt for an hour. A clean sock taped loosely (not tight) over the paw protects the nail while it scabs.
If the nail is dangling or torn at the base (not just the tip), or if bleeding doesn't stop after 15 minutes of pressure — call your vet. A dangling nail usually needs trimming back under sedation.
Guidance only — in any emergency, call 911.
