We all appreciate a refreshing breeze from time to time, but when a dog stops to enjoy the wind or sticks its head out a car window, there's more to it than simply a pleasing sensation.

Another reason dogs like a little wind in their faces is because of all the information they can gather.

With 220 million olfactory cells in their snouts, dogs can detect scents up to a million times better than we can.

They also have secondary olfactory system known as the Jacobson's organ, a patch of sensory cells located in the main nasal chamber with nerves that share detected chemical information directly with the brain.

These two smell-detecting systems enable dogs to pick up on all kinds of sensory information, so when you see a dog with its face directed toward the wind, he’s not just enjoying the breeze — he's also investigating his surroundings.

Below, take a look at some happy windswept canines.
