Using photography and laboratory simulations, researchers studied how dogs raise fluids into their mouths to drink. The scientists also found that even though feline and canine mouths are structurally similar, their approaches to drinking are as different as  cats and dogs. We know cats and dogs are quite different in terms of behaviour and character, said Sunghwan Jung, an associate professor of biomedical engineering and mechanics at Virginia Tech College of Engineering.

Dogs precisely bite down to capture the water. In an instant they reopen their mouths and immerse their tongues back into the water. Although dogs do not use their tongues to actively scoop water into their mouths, it is possible that the scooped liquid has some positive effect on the water column dynamics below the tongue, the researchers said. Dog drinking is more acceleration driven using unsteady inertia to draw water upward in a column, where cats employ steady inertia,'Jung was quoted as saying by the Science Daily.

A total of 19 dogs of various sizes and breeds were volunteered for filming by their owners. While 13 of the dogs were filmed outdoors at their owners' residences, the remaining six were filmed at the Virginia Tech campus. This was a basic science study to answer a question very little was known about  what are the fundamental mechanics of how dogs drink? said Sean Gart, a graduate student in biomedical engineering and mechanics who filmed the dogs.
