Dogs’ sloppy drinking, explained

Researchers have discovered why dogs are messier than cats when they drink, Science News reports. Like cats, dogs don’t have cheeks capable of sucking. Instead, both species lap, pulling up a column of water under their tongues through inertia. But whereas lapping cats dip their tongues gently, dogs plunge more of their tongues into the water, then pull their tongues back more suddenly, the researchers reported yesterday in the Proceedings of the National Academy of Sciences. This draws up a larger volume of water, but it also makes more water splash sideways to land on the floor instead of in the dog’s mouth.
