have you checked out http://www.dogaware.com/health/kidney.html. I find these a great place to find more info on diets, prescription and non prescription for dogs with kidney disease/failure.
My one dog is eating wellness senior food which is one of the lower commerical foods out there with low phosphorus (.74%) It’s still higher than the diet foods though. Also, keep in mind, what doesn’t seem tasty to you may be tasty to your dog. Wouldn’t hurt to try it.
One of my cats is in renal failure and she loves her can food (Hills K/D prescription)
