That hog must have been domesticated... wild hogs are some mean and unpredictable sumbitches, particularly when it comes to their food. He's lucky that one ran instead of turning on him and goring him. They usually attack in packs too...

The fun begins at about 1:35... guy and his dog fight with wounded hog and 2 more hogs attack
