Things You'll Need
A styptic pen will work to stop the nail bleeding, if you have one.
No matter how careful you try to be, if you trim your dog's toenails, eventually you will cut the nail too close to the inner fleshy part called the "quick." Your dog's toenail will start to bleed so much you'll wonder if you can ever get it to stop. There are things you can do to stop the bleeding using items you already have at home. If you can stay calm and keep your pet calm, you will be able to take care of the bleeding quickly.
Elevate the paw. If you've trimmed your dog's nail too close and it's bleeding, elevate its paw above heart level. If your dog will let you, roll him over on his back. Otherwise, hold the paw as high as you can above heart level until the bleeding stops.
Help the blood clot. Corn starch helps stop bleeding. Before you start to trim your dog's nails, have a small bowl with corn starch in it standing by. Dip the bleeding toe in the corn starch; the blood should stop in a few minutes.
Clog the bleeding opening. Rubbing a soft, solid substance into the close-trimmed nail will stop the bleeding. Soap is the perfect substance for this because it also cleans the wound. Scrape your dog's affected nail across a bar of soap until the bleeding slows and stops.
Apply pressure to the wound. Use a dry, unused tea bag to apply pressure to the bleeding until it stops. The fibers in a cotton ball will slow and stop the bleeding. You can even apply ongoing pressure by taping the cotton ball in place with one or two adhesive strips. By the time your dog chews off the strips, the bleeding will have stopped.
