It's tough as our family gets old and we just want to help them be as comfortable as possible. Pal got depo injections for several years with *excellent* results. When it seemed that those weren't working as well, we did acupuncture and that got him through for a while, then the car rides to get to treatments became too much and I did Adequan injections at home. He did really well on those too, along with Tramadol and supplements. I would try giving her Tramadol both a.m. and p.m., and massaging her back and legs could also give her some relief.
It is never, ever long enough, but 14.5 is a huge accomplishment. with your sweet girl.
