🐾 The Nose Knows: A Dog’s Secret Superpower
While humans rely on sight and words, dogs experience the world through smell—and their olfactory abilities are nothing short of astonishing:

A brain region dedicated to smell that’s 40x larger (proportionally) than ours
The ability to detect odors at parts per trillion—like finding one rotten apple in 2 billion barrels

These pheromones carry a wealth of information, including:
Emotional state (fear, excitement, calm)
