This product is exactly what we need for our aging Golden Retrievers.  It's portable, which is important since one of our reasons for getting it was to get them in and out of the car.  It folds to a manageable size and can be taken along in our Saturn Vue.  It also came with instructions on how to train your pet to use and get used to it.  Valuable information, since a dog who has never used a ramp before will balk at first.  It's strong and sturdy.  We're very happy with it.
