I trail alot of wounded deer each year.Last year alone,I recovered 5 gut shot deer.A gut shot deer does not walk for a 1/2 mile before laying down without being pushed.In fact,they very,very rarely ever go 100 yards.Last year two of the gut shot deer I helped recover were still alive the next morning.Both were found less than 75 yards from where the hunter last saw them from their stand.On another case,a buddy of mine hit one around 3:00 PM.He thought the shot was perfect,even though he saw the deer stilll walking about 120 yards from where he hit it.We took the faint trail up at around 6:00pm and walked up on the deer,very much still alive about 500 yards later.I would have turned back after the first 200 yards and came back in the morning but my buddy was worried about the rain we were getting that night.Had we not pushed that deer,he would have been found almost within sight of the stand.We did recover that buck the next morning,almost where we last saw him the night before.If you don't see or hear a deer drop and think there's any possibility that you hit the gut's,don't even attemp to follow it.Back out and come back at least 12 hours later.If you do that,you'll have no need for a tracking dog.
There's no way to know if that buck never laid down.Gut shot deer don't always bleed in their bed and they don't leave blood trails for a 1/2 mile.
