Direct Pressure
Gently press a compress (a pad of clean cloth or gauze) over the bleeding absorbing the blood and allowing it to clot. Do not disturb blood clots after they have formed. If blood soaks through, do not remove the pad; simply add additional layers of cloth and continue the direct pressure more evenly.
Elevation
If there is a severely bleeding wound on the foot or leg, gently elevate the leg so that the wound is above the level of the heart.
Elevation uses the force of gravity to help reduce blood pressure in the injured area, slowing the bleeding. Elevation is most effective in larger animals with longer limbs where greater distances from the wound to the heart are possible.
Elevation of a limb combined with direct pressure is an effective way to stop bleeding.
