Royal Canin Veterinary Diet Renal Support S Dry Dog Food is an easy to digest, savory meal designed to help dogs with kidney disease. Previously labeled as Veterinary Diet Renal LP Modified Dry Dog Food, this new and improved formulation has a greater aromatic profile and tempting texture to ensure superior palatability, and even more health benefits for your dog. By enhancing nutrients like B vitamins and the fatty acids EPA and DHA, and restricting others such as protein, phosphorus, and sodium, it slows down the development of kidney problems while minimizing uncomfortable symptoms.

Rated 4.8 out of 5 by 74 reviewers.
Rated 5 out of 5 by Loves it! My 13 year old Corgi was not eating unless I cooked her food ( eggs, chicken, etc.). I was afraid she had become so spoiled during this last bout of illness that she would never eat dog food again, as she has always been a little finicky anyway. No worries! She LOVES this food! Looks forward to dinner, acts like her old self again! I chose the Savory, for no specific reason, but have a feeling she would like the other varieties too. Thanks for making a palatable food for dogs with no appetite! October 25, 2016
Rated 5 out of 5 by Royal Canin Formula S Rated Great by our Dogs! Our two retired guide dogs were eating Royal Canin A. My dog liked it (so much better than Science Diet K/D.) However, my husband's dog didn't like the Formula A at all! We needed a formula both dogs would like. The first time we put the Royal Canin S in their bowls they both dived right in and polished it off! After almost a week they still love it! Sometimes dogs with renal disease lose interest in food. It's great to see them enjoying this diet, and I hope it lasts! October 26, 2016
Rated 5 out of 5 by works well and my 9 yr old is eating it.... Recommended for intermittent or supplemental feeding.....what exactly does that mean.....why would you make such a big bag if that is the case and not a more in between size bag? Royal Canin is the only dog food company that has one plant where all their Rx foods are made. They focus on good taste but their ingredients do just what they are supposed to do. I will continue to look to Royal Canin for any Rx foods I need to get. September 23, 2016
Rated 5 out of 5 by My finicky eater is eating again! Thank you Chewy for getting this very good dog food to me ASAP! I had read other reviews and was skeptical, of course, since I had my 12-year old female rat terrier did not like the k/d at all!! This food is a smaller bite than the k/d and she is eating it without adding any thing to it! Now let's hope for good AlkP numbers..thank you Chewy for being so responsive. September 1, 2016
Rated 4 out of 5 by My Pomeranian is eating! My 12 year old Pomeranian was diagnosed with kidney disease in May. The vet had us feeding him K/D, but he refused to eat it. I asked if we could try this food. I was unable to get the smaller bag at Petsmart so I decided to order through Chewy. My first bag did not come and seemed to be lost. Chewy fixed the problem right away. When we got the food our dog ate it right away and most days is excited about eating again. I just ordered the 2nd bag and I am so impressed that I received a handwritten postcard from Chewy today welcoming me and hoping my dog loves the food! I am amazed that an online company cares this much! Thank You Chewy! I hope to be able to use this food to keep my Pom healthy for many more years. July 15, 2016
Rated 4 out of 5 by I am not sure yet I won't be able to tell if the Royal Canine Renal Support is working until I do another blood test in about a month. If you know of other dog foods that helps I sure would appreciate. And I thank you for such a good staff you have that I give them all high marks. August 26, 2016
Rated 5 out of 5 by I love Friendly customer service, fast and free shipping. Will definitely order again! August 10, 2016
Rated 5 out of 5 by Must be more palatable! Our 9 year old beagle was diagnosed with kidney failure about 6 weeks ago. He was prescribed Hills Prescription k/d. The first couple of meals went smoothly with the canned variety, then he refused to eat. We switched to a different flavor of the canned with no better luck. Since our beagles have been accustomed to dry food, we purchased a bag of the dry (chicken flavor), with the same results. Our veterinarian suggested the Royal Canin kidney formula. After reading the many positive reviews of other dogs eating better with this brand, we ordered a bag. Copper seems to be doing well and likes this much better. He has eaten this for 2 weeks! His blood work is showing great improvement. He still gets daily fluid infusions along with this special kidney diet food. June 1, 2016
