Highly recommended for older and/or injured dogs, this product makes climbing in and out of your car a breeze as it does not put any pressure on your dog's joints and knees. Durable and portable for easy storage and long lasting use due to the high quality lightweight materials used: 1680D Oxford Cloth for the steps and rugged steel construction for the frame.
