It's not on the national news because it's a hoax...and a pretty obvious one at that.
I've seen enough of these types of photos to fill up the bed of a pickup truck.
I'm also familiar with the sizes of various types of farm equipment. The tire on that front-loader is about the same distance from the camera as the hog. The front tire, visible in the lower right of the picture, is no more than three feet in height. You can see that the tire is several feet in front of the feet of the two liars in the background.
The hog can't be much over 6 feet in length, snout to rump.
