Secrets of the Snout
The Dog’s Incredible Nose
Frank Rosell
University of Chicago Press, 2018
Dogs and humans have worked side by side for thousands of years, and over the millennia we’ve come to depend upon our pooches as hunters, protectors, and faithful companions. But when it comes to the extraordinary quality of man’s best friend which we rely on most, the winner is clear—by a nose. In Secrets of the Snout, Frank Rosell blends storytelling and science as he sniffs out the myriad ways in which dogs have been trained to employe their incredible olfactory skills, from sussing out cancer and narcotics to locating endangered and invasive species, as well as missing persons (and golf balls).

With 300 million receptors to our mere 5 million, a dog’s nose is estimated to be between 100,000 and 100 million times more sensitive than a human’s. No wonder, then, that our nasally inferior species has sought to unleash the prodigious power of canine shnozzes. Rosell here takes us for a walk with a pack of superhero sniffers including Tutta, a dog with a fine nose for fine wine; the pet-finder pooch AJ; search-and-rescue dog Barry; the hunting dog Balder; the police dogs Rasko and Trixxi; the warfare dog Lisa; the cancer detection dog Jack; Tucker, who scents floating killer whale feces; and even Elvis, who can smell when you’re ovulating. With each dog, Rosell turns his nose to the evolution of the unique olfactory systems involved, which odors dogs detect, and how they do it.

A celebration of how the canine sense for scents works—and works for us—Secrets of the Snout will have dog lovers, trainers, and researchers alike all howling with delight. Exploring this most pointed of canine wonders, Rosell reveals the often surprising ways in which dogs are bettering our world, one nose at a time.

What the Nose Tells the Mind
A. S. Barwich
Harvard University Press, 2020

An NRC Handelsblad Book of the Year

“Offers rich discussions of olfactory perception, the conscious and subconscious impacts of smell on behavior and emotion.”
Science

Decades of cognition research have shown that external stimuli “spark” neural patterns in particular regions of the brain. We think of the brain as a space we can map: here it responds to faces, there it perceives a sensation. But the sense of smell—only recently attracting broader attention in neuroscience—doesn’t work this way. So what does the nose tell the brain, and how does the brain understand it?

A. S. Barwich turned to experts in neuroscience, psychology, chemistry, and perfumery in an effort to understand the mechanics and meaning of odors. She discovered that scents are often fickle, and do not line up with well-defined neural regions. Upending existing theories of perception, Smellosophy offers a new model for understanding how the brain senses and processes odors.

“A beguiling analysis of olfactory experience that is fast becoming a core reference work in the field.”
Irish Times

“Lively, authoritative…Aims to rehabilitate smell’s neglected and marginalized status.”
Wall Street Journal

“This is a special book…It teaches readers a lot about olfaction. It teaches us even more about what philosophy can be.”
Times Literary Supplement
