Dogs are really running things on Earth

There everywhere! Talking, barking, being cute, to being ferocious, and so are cats, but there pets, so everyone gives them more attention. also possibly squirrels.

My money's on the pack of hyenas

Hyenas and smaller quicker agileier, its like all video game bosses, over powered giant thing, against 3-8 players, and guess who almost always wins if they know what they're doing? the players. So I think Hyenas have a good chance.
