I don't like to be Mr. "It was 'shopped!" Guy, but (1) of course it's not real; (2) observe, for example, the letter 'S' in photo number 6; it's positioned smack dab on the boundary between two slots - we won't even speak of the 'I' in 'either' later on; (3) it's no less funny for all that.
It's not exactly heaven if it's full of the noise and stink of some people... I don't like to get into the issue of what constitutes the mythical Hereafter, but I'm pretty sure whatever Life After Death you may have leaves all the smells of living creatures behind (even Hell, where you smell the brimstone, the brimstone doesn't smell you). I think that's a standard among all religions.
But if the souls/spirits of "innocent animals" accompany humans in that Heaven, that means you will be greeted by every cow that provided a hamburger you ate and every cockroach you ever stomped. Or maybe the believers feel that canines are specially bred to go to Heaven (I'm sure a lot of them believe the same of people).
