Scented Minds: Dogs Understand a World We Can't Smell

Dogs possess extraordinary olfactory capabilities that significantly surpass human senses, fundamentally altering how they perceive the world. The area of a dog's brain dedicated to smell is roughly a hundred times larger than that in humans, enabling them to detect and identify scents from great distances, including the presence of their owners. This remarkable sense of smell allows dogs to be effectively trained for various detection tasks, achieving around 95% accuracy in identifying COVID-19 and surpassing conventional cancer tests. Consequently, a dog's perception involves an intricate tapestry of scents, providing them an understanding of their environment that is entirely beyond human experience.
