That's a dead deer. Sometimes it will take longer for blood from a deer hit high to bleed. Make sure to look up on brush and not just on the ground. Just look hard and mark your trail. It is very easy to get turned around and forget where you have walked when your head is to the ground. I take a roll of toilet paper when tracking deer. I hang it in tree branches as I walk when I find blood. It helps me keep track where I have been and where the blood is. It also makes your back trail very visible. Good luck! You will find him.
