I have seen a lot of hog damage from rooting in both GA and SC and you picture does not look like hog damage. I can tell how big that area is where the sod was taken off but it looked more like skunk damage. The hog damage I have seen looks like the damage in the picture of damage in the link below. The ground almost looks plowed up.
