These boys are right on top of things, aren't they?

COPENHAGEN, Denmark (StudyFinds.org) – A team of European scientists has successfully decoded a pig’s emotions. After analyzing over 7,000 acoustic recordings of grunts from over 400 pigs, researchers have become the first in the world to decode pig grunts into identifiable emotions recognizable across a diverse array of conditions and life stages.

Anybody that's ever spent any time around any animal can pretty much decipher its emotions.

For instance, if that asshole dog Jack growls at me, he's happy. If he growls at me, he's worried. If he growls at me, he's hungry. If he growls at me, he's in a playful mood. If he growls and then snaps at me, he's pissed.

Seriously, he's the growlingest dog I've ever seen. I can be giving him a belly rub and he'll lay there growling, but if I quit he'll spread out even more, paw at me and growl some more. 

I wish he wasn't so camera shy so I could get a video of it - it's actually pretty cute when he starts getting into his belly rub because his growls morph into grunts of contentment. You'll hear a grrrr grrrr grrr uh grrr uh grrr uh uh uuuh.
