Grasping at straws asking people on a hunting forum to help find a shot deer and speculate where it was hit. Yes, sometimes the blood indicates an organ. But, only way to possibly find your deer is to get off the computer and search. Sounds like you are likely in body search mode. Walk in arcs and look into/under all brush piles.

Tried a dog last season for a friend who made a bad shot. Dog may have helped keep on the trail a bit. Deer was never found. Dog likely not trained as well as some. It is a lab. I believe a blood trailing hound is the ticket.

Not a good feeling at all. I can empathize.
