The best way to dog proof your car is to install a variety of things into the back seat of your car. You can use a dog seat cover, like the ones we have reviewed in more detail above, to prevent any unwanted mud or dirt from damaging your seats. These will also collect any fur that your dog might shed. You can opt for a dog cage to confine your dog into one area of your car. This will be best placed in the trunk of your car depending on how much room you have to play with. If you don’t want to opt for a cage, you can install dog barriers in your car to keep your pet in the back seat or in the trunk. It will also be best to make sure that your dog is properly strapped into your car. This will prevent them from running around and distracting you as you drive. You can buy a safety leash which slots into your seatbelt and attaches to your pet’s collar or harness to keep them safe. Make sure to keep cleaning supplies to hand, too, so you can wipe up any mess that does accidentally get into your car.
