Free Range Pigs Engage in Shoulder-to-Shoulder Sparring (Dominance or Play?)

Watch this fascinating display of behavior as free range pigs lock up and push each other shoulder-to-shoulder. This type of physical tussle is common among hogs and serves a few purposes—it could be a dominance display to establish a hierarchy within the sounder, or simply a form of vigorous, heavy-contact play.

Notice the technique they use: facing each other directly and driving their weight into the opponent's shoulder. This video offers a great, unedited look at natural pig interaction in a free-range environment. What do you think—is this a friendly spar or a serious attempt to establish who's boss?
