Using a safety harness can help make the car more comfortable for your pup because they won’t have to work so hard to stabilize themselves as the car turns and stops. And if your dog is prone to MOTION SICKNESS, the harness will encourage him to face forward, reducing the likely hood of him getting nauseous.
There are seat belts for dogs that have been crash tested so there is science suggesting that your dog is more likely to survive an accident with a harness than without. Also in the event of an accident, a harness will ensure that you dog can’t run away when the best place for him to get emergency help is in the car near you.
Finally, back to the image of a dog with his head out of the window. As much as they seem to enjoy it, flying debris makes it fairly dangerous. Even a speck of dust to the eye at cruising speed can lead to a trip to the vet.
Pet owners do everything they can to take care of their pets; a safety harness is one way to make sure your dog is safe while on the road.
