Our older dog sometimes has trouble jumping into the SUV, so we bought this for him. It was very easy to train both of our two dogs to use this ramp. We have had the opportunity to use this when we go on our long hikes, we are out for hours and have two very tired dogs when we get back. They walk right up the ramp with no problems. I have had the ramp for about two months and I would recommend this ramp as it is easy to use and to train a dog to use it. We keep it in our back seat to always have it handy. I look forward to using this ramp for years to come.
