This ramp is incredibly sturdy and stable. It will hold up for many years to come and won't twist or bend at all when deployed to your vehicle entrance or any other environment where your dog may need to climb up to a higher level. This ramp can reduce or eliminate those difficulties, and can even help to prevent the pain that especially plagues older dogs with arthritis or other mobility issues, when they try to jump or climb. It is long enough to really be effective in lowering the angle of the grade for your dog, so he or she can more easily climb up to the height of the entrance to your car, van or truck. Shorter ramps can't do this. Sturdiness, stability and length require this ramp to be fairly heavy to load and unload, although an average adult man or woman should certainly be able to handle it without issue. The ramp's surface is just about perfect - a truly rubbery (maybe real rubber; it feels like it) surface which has small ridges built into it, to make great traction possible for your dog.My family just returned from a 1400 mile journey to another state with our 12.5 year old, 90 pound Giant Schnoodle, who suffers from arthritis and other joint issues, such that he even occasionally collapses because his legs won't support him. He walked up the ramp to the back of our minivan without issue, and the training to make him comfortable to climb up the ramp was easy . The ramp company includes material to help with the training.As you might guess, I think this is a great product, and I highly recommend it.
