If you dogs shaking the water off of their coats was just some sort of funny dance, you were very wrong.
The highly efficient process can actually shake roughly 70 percent of the water from its fur in just four seconds. That’s nearly three quarters of the water in the time it took you to read that last sentence.
And it’s not just dogs that have this unique ability. It’s many mammals. But why does it work so well? And how are they capable of the shake.
It’s partly due to the skin. The skin in dogs for example is very loose. Because the skin is loose, it whips around farther and faster than the backbone can. The skin travels at three times the speed of the backbone. That action generates almost 10 times as much force on the water droplets, helping fling them off.
