It’s a familiar sight to see a joyful dog with its head out of a car window, tongue out and ears flapping in the wind. Similar to how humans enjoy the thrill of a convertible ride with the breeze in their hair and the sun on their faces, dogs seem to relish it too. But what is it about dogs that drives them to stick their heads out of a moving car? And is it safe?
Why Do Dogs Love to Stick Their Heads Out of Car Windows?
Dogs are naturally inclined to seek adventure, especially those that involve fresh air and exploration. Sticking their heads out of the car window offers a sensory overload for your dog. 'It’s an extremely stimulating experience for them—the scents, the sensation of the wind, and all the sights they can absorb,' said veterinarian Dr. Cathy Meeks in a 2016 interview with The Dodo.
Dogs have over 100 million sensory receptors in their noses, far exceeding the 6 million found in humans. The area of their brain responsible for processing scents is about 40 times larger than ours. When dogs exhale through the slits in their nostrils, the air moves around, introducing a wide variety of new, fascinating odors. Letting them stick their heads out of car windows (or any open window) allows them to fully experience the outdoors through their sense of smell.
The visual experience is just as thrilling. While dogs perceive fewer colors than humans and often struggle with near-sightedness, they excel at detecting moving objects. In fact, dogs have 10 to 20 times better motion perception than people. This means the scenery whizzing past in a car may appear blurry to us, but it’s likely much clearer for a canine passenger.
Between the delightful smells and exciting sights, a dog sticking its head out the window is essentially indulging in a sensory celebration. However, this isn’t always an enjoyable experience for every pup—some dogs may suffer from car sickness or become anxious due to the surrounding motion and noise. And it can also pose significant dangers.
The Risks of Allowing Dogs to Stick Their Heads Out of Car Windows
While many dogs—and their owners, who enjoy watching their pets' faces flapping in the wind—find joy in riding in cars, it’s not without its risks. Large chunks of flying debris, nearby vehicles, and branches or poles can be dangerous. Even smaller objects, like pebbles, dirt, flying insects, or other airborne particles, pose threats by potentially getting into a dog’s eyes, leading to injury or infection.
If the vehicle’s driver suddenly brakes or swerves while a dog has its head out of a wide-open window, the dog could be thrown from the car. Additionally, dogs might accidentally roll up the window with their paws, causing injury to their head, chest, or neck. There’s also the risk that they may try to jump out of the car to chase something—or lose their balance while attempting to leap.
To ensure the safety of all passengers—both human and canine—avoid letting pets roam freely in the car or sit on your lap during rides. A dog on the loose can obstruct the driver’s view or disrupt the passengers. If your dog tends to get restless, move around, or try to leap out of the window, it’s safer to place them in a crate or secure them with a pet seat belt or harness.
You can still give your dog an enjoyable sensory experience while keeping them safely restrained. Simply crack open your windows (making sure your dog can’t poke its head out if loose) to let them breathe in the outdoor scents while being safely secured in the car. This way, everyone can have a pleasant—and secure—ride.
