UNDATED (CNN) -- Behold in slow motion how dogs shake themselves dry. Wet dogs shaking have left researchers shaking their heads in awe.
It may not be research that's earthshaking, but it's definitely dog-shaking. And pig shaking. And even rat-shaking!
Most of us try to avoid getting showered by the dog shake, but researchers at Georgia Tech decided to study it. Dr. David Hu with Georgia Tech says, "They can actually do a miraculous job of drying themselves."
They used a high speed camera to record the shakes, resulting in images so stirring that the journal Nature put them to waltz music.
A mouse shakes around 30 times per second. Hu says, "They basically compensate for their size by shaking faster."
While dogs shake about four times a second leaving them 70 percent dry within one to 4 seconds.
Now we humans don't want loose flesh, but on a dog it comes in handy. That loose skin increases the speed at which the water is whipped away, while the dog's backbone goes back and forth only 30 degrees, increasing the force nine times. Hu says, "The skin goes 90 degrees right, 90 left. Only possible way it's loose enough to perform whipping action around the body."
Mammals have mastered what Devo preached back in the 80s.Whip it! Whip it good!
Hey, a vigorous whipping sure beats sitting under the blow dryer. The researchers even went to the zoo and recorded a lion. Dr. David Hu says furry mammals probably developed the shaking mechanism to avoid staying wet and getting hypothermia. Goats do it. Even sheep shake.
The Georgia Tech team even managed to x-ray shaking. But a kangaroo is built for hopping, not shaking. Hu says, "It can't really shake. Has this sort of large buttock and it can't really shake that around so it just shakes its head."
Hey, whose butt you calling big?
