I think it is crazy how they learn tricks like this and get away with it for a long time. It also gets me just how many hogs will "squat" or lay down and the dogs just run right past him. I have seen hogs do that in a 5 acre pen and grown dogs run right by him. Makes you start to question how often that happens in the woods.
Matt, Bryant came down and hunted with us a month or so ago. The dogs bayed a hog in some thick cover so we sent in the CD's. It broke, ran right towards bryant, and layed down about 5 feet from him in some thick stuff. He froze and when one cur opened up on it he had a front row seat for the catch.
