This dog ramp was just the thing I needed for my elderly 95lb lab.  She was able to walk safely up it into the back of my SUV.  I did 'train' her with treats along the ramp the first couple of times but otherwise it was quite easy.  It certainly held her weight and I never felt insecure about her walking on it.  It is a little bit heavy to handle and doesn't fold up too small so after using it, you do still need much of the back of your vehicle to store it for descent at your destination.
