Hi Diane S,
The only food I’m aware of is Dave’s restricted diet can. It’s phosphorus level is .17% as fed and has a G/A minimum/maximum of .02%-.22%. Almost every other commercial food adds phosphorus to meet daily requirements.
Here’s a link to Dave’s:

When you’re dealing with kidney issues, you should feed a wet diet (as opposed to any kibble) to help keep the dog hydrated properly. Home cooked diets are often the best option. The balanceit website will work with you vet and your dog’s particular numbers to provide homemade recipes. Another helpful resource is dogaware:

Good luck with your pup. I’m not sure what type of kidney disease you’re dealing with, but I wish you the best.
