One thing i've noticed over the summer is a group a dogs running one, then at one point in the race just fanning out and falling apart. Like the hog disappeared in thin air... seen it several times this summer. We just scratched our heads and figured it was because of the super dry conditions?
Other times, the hog will hit a big thicket, round around in it for an hour or two in circles... then sneak out the back door. The Garmin screen looks like a crackhead with an etch-a-sketch. By the time the dogs line it out, that hog is usually in the next county.
I guess you could call that a loose? Cause it sure ain't from lack of bottom.

Wow, I really thought that my dogs just sucked because I have seen this happen to me a whole lot. It's good to see that even the professional internet hog hunters have the same problem at times.
A couple of weeks ago the pups jumped a hog and ran it to some thick stuff a few hundred yd off in a bottom and spent over an hour in less than five acres before giving it up. They tried hard but I really think he circled and zig zagged around and snuck out.
Also the most seasoned dog I have has been in the woods just over a year and has never really run with an older dog but is just working off of natural ability. There are times that I think that they just don't have the experience to figure every track out, but they are learning.
