What it’s like to be...
A dog
Their superpower is not to be sniffed at. And with training, we can sharpen our own noses too

During the past 18 months millions of us, while suffering from Covid-19, have developed a temporary loss of smell. Although a strange and unnerving symptom, in general it has not been a disabling one. Humans have an ambivalent relationship with scent—largely rejecting olfactory information in favour of sight, sound and touch.
How different it would be for a dog, a creature whose experience of the world is imbued with scent. To get an idea of how important smell is to dogs, look to their physiology: while human noses contain about six million scent receptors, a collie’s might contain 200m; a beagle’s, 300m. Around an eighth of their brains is devoted to processing scent information.
