Kidney Disease in Health and Genetics Posted May 17 · Report reply My Pip, who will be 14 in July, was dx with early renal failure a couple of years ago. He’s kibble fed, so I immediately switched him to the lowest phosphorous commercial kibble I could find (FirstMate senior weight control). The phosphorus isn’t quite as low as with the Rx diets, but he’s getting slightly lower protein and it’sa *high-quality* protein (vs most, if not all, Rx diets, which use corn as the main protein source). Thinking has definitely changed over the years and my preference is to slightly limit protein, but to use high quality protein, and to limit phosphorous. Pip’s bloodwork values have been holding pretty steady and I’m good with that. Eventually he may require fluid therapy, but even that isn’t a difficult undertaking. I have a friend who managed two elderly dogs with renal failure. I took care of them when she had to travel. She did homemade diets for both, tailored individually by a nutritionist. They both did really well for quite some time. I’ve had numerous cats who required management for CRF. Some went years on special diets and sub Q fluids. Most side effects can be managed. I always felt that as long as my pet still seemed to enjoy life then I’d do what I could to keep them happy and comfortable. J.
