That may be the way to go for sure. I know we don't want to continue with the Hill's K/D that our vet prescribed, and most of the commercial foods are too high in phosphorus. Any good links to a good raw diet?
Ask and you shall receive!
Here's the website Jon (jdatwood on here) and I started for the sole purpose to educate people on the why's, how's, benefits, etc of raw feeding. It's based mostly on first and secondhand accounts by members on here as well as other nutrition forums. I suggest you read through all the pages to get started!

I hope you choose this route for your dog. It really will open a new door for your dog, instead of settling on "keeping your dog comfortable" because there's no way to recover the damage done to his kidneys, but you sure can try your hardest to keep them from getting more damaged!
