To us, that may simply smell like…
a person.
To a dog, it’s much more complicated.
It’s a collection of individual scent clues.
Dogs have specialized anatomy that helps them process these odors, including a highly developed olfactory system and a vomeronasal organ, sometimes called Jacobson’s organ, that is involved in detecting chemical signals such as pheromones.
And there’s another fascinating detail.
Dogs don’t simply take one quick sniff and immediately know everything.
They often sniff repeatedly because they’re gathering and processing information.
That’s why you’ll sometimes see a dog stop during a walk and spend what seems like an eternity investigating one tiny patch of grass.
You may see…
nothing.
Your dog may be reading an entire story.
Another animal passed through.
Someone walked by.
Food was dropped.
Another dog left a scent.
Something changed.
To your eyes, it’s just grass.
