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.
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.”
