Nose range?

Lance I will definitely agree that, too many variables to have a concrete answer on time. The point I was trying to make with my previos post is that a hog can cover more country in an hour than a hog can make up given the opportunity. I have watched hogs in west texas come to a feeder from over 2 miles away, stop eat and I would lose sight of them 2.5-3 miles away in the opposite direction. All of this transpired in less then 30 minutes. I have never hunted with a dog that could pick up a track and trail a group of hogs that far and have a cought hog at the end of it. At the rate they were moving they would have been 10 miles away in an hour. Most of the time where we hunt if a dog takes a track and follows it for more then .5 mile with the track really heating up or finding the hog then then they turn back and make a loop. I have seen dogs impress the fire out of me and on the same hunt not be able to smell a hog that ran across the road 30 seconds ago. There are alot of things that can't be explained when it comes to scent and tracking ability.
