Running on their mind or not....Oconee you said it yourself....in the open you've seen your dogs grab nuts/hams....whatever to stop one right?
I've heard other guys say it but I personally have never seen a hog want to keep running when dogs are stretching his sack.....or spinning him like a top. That hog is looking for brush to back up into. IMO when it comes right down to it....terrain is the number 1 factor that determines whether a hog can run or not.
I totally agree with you Kevin...a dog or pack that pulls enough hair will have one stopped in open country...but once you get in that time of year where the weeds are thick and tall the game changes in the hogs favor...some places it doesn't matter whether the leaves are down and the weeds are dead during the winter months because it is thick year round...seems the first place a hog wants to run towards is always the thick briars/thickets...
