Answer
I'm sorry to hear about your dog, I had a cat with a congenital kidney problems.  I don't have any medical training, so my only suggestion would be to see if there is a vet school in your area and take your dog there.  They often have the latest and greatest treatments and might have a new drug or treatment that they are testing that might give your dog some extra time.  Good luck.
