What to do if trimmed dogs' nail too close and bleeding?

If you've trimmed a dog's nail too closely and it starts to bleed, remain calm to avoid stressing your pet. Apply a styptic powder or cornstarch to the bleeding nail to help clot the blood; press it gently for a few minutes. If the bleeding doesn't stop or if the nail appears severely damaged, consult your veterinarian for further advice. Keep the dog calm and avoid walking on hard surfaces until the bleeding has ceased.
