Dog kidney failure: Is vet-recommended kibble or homemade diet best?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 13 years old | 27 lbs

My dog has been diagnosed with early stages of kidney failure. My vet has recommended that we put him on a low protien eating diet with Kibble - Brand Royal Canin Renal Support. I've researched online that the best thing to do is to give him high quality protein (low in phosphorus) and a natural home made diet. Should I go low protein (kibble) or high quality protein for his diet?

I would definitely go with the Royal Canin Renal support. This food is specifically formulated for dogs with kidney failure. The problem with a homemade diet is that it is extremely difficult to get the correct balance of nutrients, and you could accidentally end up giving him too much phosphorus in trying to meet his other nutritional needs. Too much phosphorous is detrimental to his kidneys while they are failing, and it's best to stay with a specially formulated food recommended by your vet. Keep in mind as well that the information you are getting from the internet is not typically provided by vets, but rather lay people who have no training in animal health or nutrition. In my opinion, when it comes to the health of your dog, it's best to listen to the experts who have done the training and have the knowledge to correctly treat your dog, who is the vet. I hope this helps you!
