Your Dogs Sniffer Senses May Be More Powerful Than you Think 

Specially trained dogs have been known to sniff out explosives, drugs, missing persons and certain cancer cells, but author Alexandra Horowitz tells Fresh Air‘s Terry Gross that extraordinary olfactory abilities aren’t just the domain of working dogs.

Horowitz says that all dogs have the ability to create “a picture of the world through smell,” thanks, in part, to the design of their snouts. A canine’s nose is “stereoscopic,” she explains, which means that each nostril is controlled separately, allowing the dog not only to detect a particular smell, but also to locate it in space.

In her new book, Being a Dog, Horowitz discusses the mechanics of canine smell and explains how dogs can use their noses to understand what time of day it is or whether a storm is coming.

Horowitz warns that pulling dogs away from smell-rich environments, such as fire hydrants and tree trunks, can cause them to lose their predisposition to smell. When dogs are living in “our visual world,” she says, “they start attending to our pointing and our gestures and our facial expressions more, and less to smells.”
