Unravel the Deeper Meaning of Your Dog's Behavior

12. Sniffing the Air

Dogs rely heavily on their sense of smell for various purposes. They possess an impressive 220 million olfactory receptors, while humans only have around 5 million. Dogs can smell at least 1,000 times better than humans.

When dogs sniff the air, it can indicate that they are detecting potential danger approaching or they are attempting to track prey. During this time, they will remain completely still and maintain silence to avoid being detected by their prey. Dogs have the remarkable ability to distinguish different smells.
