Available in multiple aromatic profiles, in both wet and dry food, the diets can be easily mixed or rotated to provide multiple feeding options.

  • 3 dry and 3 wet options for both cats and dogs providing 9 different feeding combinations
  • All RENAL products have similar nutritional profiles, easing the transition when introducing product rotations without concern for digestive upset

Rated 5 out of 5 by from For kidney stones My vet put my dog on this food more than two years ago. It seems to be doing what it's suppose to do. No issues with the kidney stones moving nor increasing in quantity.

Rated 5 out of 5 by from my yorkie loves this and the small kibble makes it you don't know what a relief it is to see a dog eat that was refusing food before. My Yorkie has stage 2 kidney disease and eating has been an issue for her, I have 5 bags of different food in my kitchen to prove it. But one day on your food and she is actually eating again with more interest. Can't thank you enough!

Rated 5 out of 5 by from My Dog Loves it! This food was recommended to us by our vet. Our dog has only one kidney and must be on a strict renal diet. We have been feeding this to him for several years and he loves it. Every morning and evening he cannot wait to eat. He gobbles up his food and is happy as ever. This is the only food our dog gets. We can't give him any treats, to instead we give him a piece or two of this food. He is always happy to get them! Thank you Royal Canin for having this food and increasing our dog's lifespan.

Rated 5 out of 5 by from Only food my dog eats. Since being diagnosed with kidney disease, my dog has taste tested many special diets. This is the only way she likes well enough to stick with it. Thanks Royal Canin.

Rated 5 out of 5 by from My dog loves ot! My dog has been eating this formula for a long time. He only has one kidney, but you'd never know it from his behavior. He is the happiest dog you've ever seen. Every morning and evening he is so excited to get this food for his meal. We also give it to him as a treat when he needs to go into his crate when we leave the house for a while. He just had his blood work checked, and his numbers came back great! Thank you Royal Canin.

Rated 3 out of 5 by from Okay dog food The dog food smells great but I'm just not happy about the ingredients, you would think paying $60 for a bag of food would mean the ingredients are good, but they are cheap fillers and by products and the first ingredient is corn! Really wish my dog didn't have to be on this food.

Rated 5 out of 5 by from Oh Kidney My Kidney We found out through blood work for a dental cleaning that are little lady had kidney issues. Being 14 years old, we were worried that we would not find a food that she liked and/or didn't flare up her food allergies. Royal Canin Renal type S was the ticket! The first time we gave it to her, she gobbled it right up and we were so excited that we didn't have to go through the painstaking "food search"..we had found It! We are blessed that she just turned 15 a few days ago and are happy to have found this food to help support her new lifestyle.
