Seat covers and liners will keep the seats of your car in better shape for a longer time if you travel with a dog in the car.
Things to consider:
Stain Stoppers - Seat covers and linens, no matter how machine-washable, will last a lot longer if you and your dog travel with some stain and odor remover, urine stain removers, and deodorizers.
Trim the Nails - To ensure that the seats of your car, as well any seat covers and liners you may use, last as long as possible, get yourself some dog nail clippers and clip your dog's nails before you get in the car.
Car Sick- If your dog gets motion sickness, you will be incredibly glad that before you put her into the car, you covered your back seats first with seat covers and liners.
