Identify Where the Bullet or Arrow Struck
Take the time to assess the blood that you find along the trail. Is there any stomach fodder, suggesting a gut shot? Frothy blood with bubbles indicates a lung shot. Look for hair and tissue on the ground, and at the relative position of the blood on vegetation. If there's blood on both sides of the trail, the bullet or arrow likely passed through.
Identify Direction of Travel**
Blood drops that fall perpendicular to the ground create round spots, but blood that strikes the ground at an angle creates an oval or elongated drop mark with a tail. When trailing deer, the tail of a drop of blood points in the direction of travel. If drops of blood are perfectly round, the deer was standing still when he bled.
