Keep your pet dog safe while traveling by using a dog harness for car. A dog harness will give your canine companion the best possible comfort and support while you're traveling for long distances or even when just driving around town. With the range of sizes available, it is easy to find the right-sized harness for the type of breed that you have. Booster seats are also available for smaller dogs, especially those who have the innate urge to look out the window while traveling inside a vehicle. Many of these easy-to-use harnesses are sold in a variety of colors and styles too.
