Dog's Nose

Since I was a child I knew dogs were quite good at sniffing. As I get older, I get more curious about things. Why dogs are better sniffers is intriguing. The New York Times, for Learning From Dogs as They Sniff Out Their World, interviewed Dr. Alexandra Horowitz, a professor of cognitive science who runs the Dog Cognition Lab at Barnard College. Now I know why dogs are better sniffers. Sniff researchers have learned humans have about six million olfactory receptors. Dogs have 300 million. Humans sniff once per second-and-a-half. Dogs sniff 5-10 times every second. Dr. Horowitz said that a dog’s anatomy is designed for sniffing. She said, “This gives them a continuous olfactory view of the world.” If you want to learn much more about dog sniffing, take a look at Dogs’ Dazzling Sense of Smell.
