A dog's nose reveals a universe far richer than human eyes could ever see. With hundreds of millions of olfactory cells, dogs detect scents at concentrations up to 100 million times lower than humans can. Their sophisticated nasal structure lets them locate where smells come from and even distinguish emotions or illnesses in people. For dogs, every street corner holds the stories of the past, present, and future—written in invisible scent.
