Dogs shaking off water is a common sight, but have you ever wondered why they do it? Dogs shake off water to remove excess moisture from their coats, which helps to prevent skin irritation and infections.
This behavior is deeply ingrained in dogs, thanks to their wild ancestors who needed to shake off water to stay warm and dry in cold climates. In fact, studies have shown that dogs' ancestors, such as wolves, would shake off water to remove excess moisture from their coats before returning to their dens.
Dogs shake off water by rapidly vibrating their muscles, which creates a forceful movement that helps to expel water from their coats. This movement is so forceful that it can even create a spray of water, much to the amusement of their owners.

The Wet Dog Shake
The Wet Dog Shake is a fascinating phenomenon that has puzzled many a dog owner. It's a way for dogs to shake off water from their fur, and it's not just a cute trick - it's also a remarkable example of physics in action.
Dogs can shake off water at rates of four to seven times per second. This is because they need to generate enough centripetal force to release the water from their fur.
Jerry, a brown toy poodle, was the inspiration behind a study on the wet dog shake. His owner brought him to a scientist, who built a wet-dog simulator to study the phenomenon.
The simulator showed that 12 times earth's gravity was the minimal acceleration needed to remove the smallest drops from the fur. This is the same acceleration that Jerry was generating when he shook off water.
Bears shake at four times per second, dogs at four to seven times per second, rats at 18 times per second, and mice at a dizzying 29 times per second. The smaller the animal, the faster it needs to spin to generate the same forces.
Smaller animals have a smaller radius, which means they generate less centripetal force. To make up for this, they need to spin faster to release the water from their fur.
