I purchased this ramp a little over 10 years ago when I bought an SUV and did not want to lift my elderly 65 lb dog into the rear.  He caught on right away and this worked so well he never missed his car.  I got 2 puppies 8 years ago and still have the SUVs - didn't want to damage their puppy legs so have used this right along every single day into their older years!  It has held up remarkably well and I can easily fold it and stow it in the back when it is not being used.
