Dachshunds

I have a dignified 14yo male miniature daccy (Muffin) who, six months after moving to a new house with lots of stairs is now (sensibly but suddenly) refusing to climb them. I'm fairly sure that unless I can manage to re-home him somewhere without stairs his back will go soon. While I explore that option I'm interested in any suggestions of non-surgical, non-heroic measures (given his age etc)that might buy some time. For example would a course of steroids or anti-inflammatories probably be useful? His health is otherwise pretty good, especially for his age, other than recently having had a number of decaying teeth removed.

Interested in peoples thoughts/views/experiences. NB: Funds are extremely tight. As an interim measure I've started him on meloxicam

After 5 months i thought it might be useful to post an update. Having used meloxicam and prednisolone initiall for 5 days his symptoms improved. Although not tubby I also further restricted his food intake and made it less calorific (LEAN bones for example). the result is a soprichtly happy geriatric for the moment at least. At one stage he started to re-develop symptoms so I provided another brief prednisolone only course, and the symptomsd quickly abated. i know I'm only buying time but it seems like a good deal from where he's lying.
