Odds are decent you've seen this video of dogs shaking in super slow-motion (and if you haven't yet, you should – it's a slobbery good time). What you may not know is that there's actually some really fascinating science behind the wet-dog (and, more broadly, the wet-mammal) shake.
Andrew Dickerson studies how wet animals shake to become dry animals. Last year, in fact, he published the results of a study that examined the wet-shakes of 33 different animals, including some intriguing findings relating shake-frequency and overall animal size.
When a dog gets wet, what does it do? Answer: it shakes, and very efficiently — a large, soggy dog can shed as much as 70% of the water in its fur in just four seconds.
