I would do it! It may take him a while to figure it out but I think once he does it will be worth it. I have a step stool for my bed because the girls had trouble getting up and down. Lady figured it out right away, I tried for MONTHS with Gracie luring her up and down with treats, etc. but she never caught on. Until about 5 months later, long after I had given up trying to teach her, when all of sudden she started using the stool!
