It's a lot different than hunting the woods. A lot of dogs used to hunting the woods won't cast well into grain... I like to hunt the edges of the fields at daylight and let the dogs trail the hogs to their bedroom.
This is a good game plan. Been having some decent luck these past two weeks with this same strategy. Using just one dog just before daylight. Only problem is if the corn has water in it. They will lay up right there and never leave.
