I call shennanigans. The pig may be that big, but the picture looks suspect somehow. If you look at where the boy is sitting, it looks like he is sitting away back from the hog, making the hog look bigger. If the hog is 9 feet, it would be almost twice as long as the kid (assuming an 11 year-old is around 5 feet tall). The pig, even with its legs curled up underneath it, appears to be way bigger than that in the photo.
Also, if you look at the Hogzilla picture, Monster Pig appears to be way bigger than Hogzilla, even though they are fairly comparable in size.

It also doesn't help that dear old dad has already put up a website about Monster Pig.
Something doesn't smell right, but that's just the skeptic in me.
