Not with any hog I've come accross & I've hunted them in Texas, Carolina, Georgia, Alabama, Mississippi, Namibia, South Africa & Spain. I'll take a week of hog hunting over a full season of deer. I love hog hunting!
That kind of thing I have never, ever seen. OK, Their eyesight & hearing isn't perfect, but you simply cannot beat their noses. Wild hogs are very aware of what's going on around them & 99% of the time a wild hog will high-tail it as soon as it knows you're in the county. To see this behavior makes me think that it's a farm raised pig. That & the weight. Even in South America & Eastern Europe hogs rarely get to 400lb without man-supplied feed. Available forage simply isn't nutritional enough on it's own to let a hog get to that weight.
Firstly I'd say that the film is of a free-ranging, farm raised hog & secondly I'd have to say (sorry y'all) that it died fairly quickly. Death ain't ever pretty & it's seldom as quick as you see on TV.
