It all starts with shot placement. If it's right, you basically have no problems. Muscle hits will clot quite quickly. BUT, deer do tend to run out of blood right at the end of their trail. SO, when the blood slows down, so should you. Just because you saw big drops and puddles before doesn't mean you have to stop looking for those tiny tiny specks. BUT, again, it all starts with shot placement. If that's good your job is usually easier.... but that's not to say things can't happen to make it hard. LOTS of BLOOD does not necessarily mean "GOOD" blood.
