Scientists Study the Wet-Dog Shake

Anyone who has had a wet dog shake nearby has suspected he ends up wetter
than the dog. There's a reason why dogs shake dry rather than drip dry. 

 

Researchers at Georgia Tech used high-speed cameras to film dozens of wet
animals, from mice to bears. Watching them shake in slow motion revealed
they shook 70 percent of the water off their coat in just a fraction of a
second.

 

Although fur is great for keeping animals insulated, when it gets wet,
surface tension traps water next to an animal's skin. In cold weather, that
can lead to hypothermia. Shaking is more efficient at getting the water off
than evaporation, researchers found.

 

And not all shakes are created equal. Turns out, furry mammals of different
sizes adjust their shaking speed to get as dry as possible using the least
amount of energy. That means the smaller the dog, the faster it shakes to
dry. Additionally, researchers found that the loose skin that whips around
as the animal changes direction is crucial to the efficiency of the shaking.

 

There is a reason behind the research: Scientists think their findings can
lead to technology for instruments like camera lenses or solar panels that
need to stay dry but are in hard-to-reach places.
