Our elderly Border Collie mix has arthritis in her back and one hip, so nowadays she can't handle the steps into the trailer. Last year we got a ramp to make it easier, but immediately had issues with her feet slipping on the ramp, which had a surface like sandpaper. After checking her feet though I realized the hair had grown long on the bottom of her feet, as I hadn't checked it in a couple of months. I trimmed the hair and she handled the ramp with ease. Fortunately the ramp stores easily and handles well over her weight. I recommend it for all elderly dogs, and it saves my elderly back too.
