A boot liner is a simple piece of material that is used to cover the Boot space before you place anything in the boot. It is used largely to protect the booth from being damaged by whatever is being ferried in it. For
protection purposes, it protects the boot against smears and scratches. This usually end up costing you several dollars monthly in professional cleaning services.
In the case of a boot liner for dogs, you get to avoid the inconvenience that comes with having wet dogs on your boot, their muddy paws especially when coming from a walk. You also avoid any smears and spills staining the boot room and furs being spread all over your car. A good boot liner for dogs does not just protect the car, but also ensures the dogs are comfortable in the boot even for long distances without developing soreness.
