Scavengers 'R Us
Dogs, unlike their catty counterparts, are not carnivores. But they're not like your garden-variety omnivores, either. For tens of thousands of years, these opportunistic scavengers have devoured anything and everything, as long as it fulfilled their basic dietary requirements.

Instead, dogs today seek out plants as an alternative food source.
