We tried the ramp mostly for our older 9 yr old dog (looks just like crusoe but bigger) who had a bout with IVDD this past summer. We did six weeks of crating rather than surgery, and he walks and runs just fine now, but still some weakness in hind legs for climbing and jumping (which we try to prevent him from doing). So at first, we had to tempt him with treats to make the incline climb on the ramp, but even then unless he kept up enough momentum, he had trouble making it all the way to the top. So my husband added some wood strips across the ramp at intervals, screwed into the ramp over the carpet. That gave him enough to grab up on and push off of from the back to keep moving up the ramp. Sometimes we give his butt a little boost for the last part onto the bed.
Our 5 year old 10 pound doxie flies up the ramp and down again, because she thinks she is a cat. She can almost leap to the bed from the floor. But we feel better that she has the ramp to protect her from future IVDD issues. While it was no problem to lift our older, heavier dog up to the bed, we were very worried that he would jump down and then be paralyzed. So now he has a safe way to get down from the bed.
Because we have both a lake home and a regular house, we tried it out at our regular house first and once we were sure it would be the solution we were looking for, we ordered another one for the lake house. We would have preferred another walnut stain one, but those were out of stock, so for the lake house we did a whitewash finish. My husband appreciates the ingenious anchoring system. I like how easy it is to detach the anchor and fold up the ramp and slide it under the bed, if we want it put away when we entertain.
