Digital DeconstructionHow dogs shake off 70% of the water on their fur in seconds
Everyone’s seen a wet dog shaking to get dry. But why do they do it and how does shaking get dogs dry so fast? Scientists set off the find out, also releasing an excellent slow-motion video of dogs drying themselves!
Secrets of the ‘wet dog shake’ may some day lead to self-drying machines: study:
Georgia Tech researchers looked at the way wet dogs dry themselves and found that they can shake 70 percent of the water off their fur in four seconds, thanks to their loose hanging skin.
They used high-speed cameras to study the canines in motion. Key to a dog’s drying power: while its backbone can can only go 30 degrees in either direction, its loose skin can swing a full 90 degrees.
“The loose skin lets the dog whip much farther and faster to the left and the right. This results in three times the amplitude, three times the velocity and nine times the centrifugal force,” engineer David Hu told the Daily News.
Dogs are fascinating.
