Fluid dynamics explain what happens when dogs drink water

If you've ever watched a dog drink water, you know that it can be a sloshy, spilly, splashy affair -- in other words, adorable. Behind all of the happy, wet messes, however, lies the mechanical logic of carnivorous compensation -- dogs splash when they drink because they have the cheeks of a predatory quadruped. By studying the drinking habits of various dog breeds and sizes, researchers have recently identified and modeled the fluid dynamics at play when dogs drink water.
