Friday curious. Dogs against Covid
Turns out, dogs can detect COVID-19 through their sense of smell. Not only have dogs shown that they can detect COVID-19, they’ve also been extremely accurate in detecting breast cancer and the onset of epileptic seizures. They have up to 300 million olfactory receptors in their noses—whereas humans have only about 6 million. To put the difference in perspective, in two Olympic-size swimming pools, these sweeties can detect the presence of just one spoonful of sugar. It really does take one to know one.
