muzzyman I am no expert on tracking, but I think you may want to try to retrace your steps back to the point "till I realized I was headed into a deep hollow where a stream ran". Go back to the point you made this realization and rather than heading straight for the stream, either try to continue following the little blood you have found, if there is none then start your circle search again, until you either pick up blood or find him. I have a strange feeling he may have in his final moments wondered off to on side or the other and expired very close to where you headed for the stream. Correct me if I am wrong in my assumption. BTW if it is legal you may want to take a dog with you. Good luck.
