When we get wet, we need a towel to get ourselves dry.
When a dog gets wet, it needs to shake its body. A study
showed that a wet dog can throw off half the water on its body
by shaking for less than a second. Actually, this common act
of dogs works better than a washing machine. The study found
animal shaking starts with the head and ends with the tail.
During a shake, the animal's head, body and skin all move.
Smaller animals must shake faster than bigger animals to get
water off. For example, in one second, a rat can shake 18 times,
a dog 6 times, and a bear 4 times. Bigger animals can get their
bodies dry with fewer shakes. For animals, shaking is not only
lives.
