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.

Dog loves it

My dog had slowed his eating and was refusing the food I had that was another renal formula. The vet recommend I try Renal Support S and he loves it! He is eating normally again and I am no longer worried about him giving up.

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.

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!

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.
