My toy poodle has developed incipient kidney disease. As a retired physicist I have the time and the ability to do research. I’ve found that My Perfect Pet low phosphorus frozen food is the best food available commercially. You should also check the web site DogAware.com for some good information about low phosphorus foods.
Hills k/d dry food and Royal Canin Veterinary Diet renal support dry food are both poor foods judging from the ingredients list. My vet prescribed Royal Canin for my dog and I refused to feed it to my dog. Hills k/d canned food appears much better from the list of ingredients and is much lower in phosphorus than Royal Canin Veterinary Diet Renal Support canned food.
Mixing Hills k/d dry food soaked in sodium-free chicken broth and letting it sit overnight in the fridge might help make the food more compatible and easier to digest.
Good luck.
