Use a soft cloth, leash, or commercial muzzle. Skip this for cats or pets struggling to breathe. A scarf tied around the snout works in a pinch.
Press a clean cloth or gauze firmly onto the wound for a full 5 to 10 minutes without lifting to peek. Steady, continuous pressure forms the clot.
For a leg wound, raise the limb above heart level while continuing pressure.
Wrap with gauze and self-adhesive bandage (not human medical tape — it sticks to fur). You should be able to slip a finger underneath. Toes should stay warm and pink.
Any wound deeper than a scratch needs vet evaluation. Bites from other animals always need vet care for infection risk and possible rabies follow-up.
Guidance only — in any emergency, call 911.
