When your dog sticks its nose out of a moving car window, it’s experiencing a sensory overload. The open road, the wind in their fur, and the various scents rushing by all contribute to an exciting experience for them. Dogs have a wider visual field and can detect movement better than humans, making the passing scenery a blur to us but sharp to them.
But it’s the smell that really gets them excited. With 300 million odor receptors compared to our 6 million, dogs rely heavily on their sense of smell to interpret the world around them. Their unique nasal anatomy allows them to continuously smell and process new odors, making it a primary way of experiencing their environment.
