  • All RENAL products have similar nutritional profiles, easing the transition when introducing product rotations without concern for digestive upset

Product Reviews
Royal Canin Veterinary Diet ® Canine Renal Support S dry dog food is rated 4.8 out of 5 by 40.
Rated 5 out of 5 by from Great product! My vet put Holly on this due to her forming crystals in her urine but also put her on the diet version due to the fact that she is prone to gaining weight from being on prednisone for mobility issues. This has been the one dry dog food that she eats with no refusal at all!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Highly recommended! I’ve been using this dog food for three years now. My Rescue lab mix will be six in February. He started frequently having to go out to urinate and we took him to the vet. He was diagnosed with kidney and liver failure. My Vet narrowed it down to- due to chewing on a stick that had bird feces on it. The vet prescribed Royal Canaan dog food for his special diet. I believe it saved his life.

Rated 5 out of 5 by from Very tasty My border collie Lori was diagnosed with protein losing nephropathy over two years ago and and given a very poor prognosis she is doing great with most everything. I attribute her longevity to the few medications and her diet . She eats exclusively Royal canin renal. Thanks for providing her such a great diet that she loves.

Rated 5 out of 5 by from Extremely palatable!! My sheltie Toby was diagnosed with the early stages of renal failure. I switched him from his regular food and to my delight he LOVES this food. Usually prescription diets aren't really what our pets have in mind but he likes this even more than his old food. Thank you Royal Canin. One less thing I have to worry about :-)

Rated 5 out of 5 by from My Dog Loved It! My dog progressed from early kidney disease to late stage disease prior to his death. Other brands of dog food he turned away from, but he always ate Renal S, and loved it. I knew it was an exceptional quality food and was beneficial to his health. I was comforted to know that he was enjoying his food until the end.

Rated 5 out of 5 by from My Golden Girl likes it !! After being diagnosed with early stage kidney disease, my veterinarian recommended Royal Canin. My Golden gobbles her food up and her last blood work confirmed that the renal support diet is doing the job of supporting her kidney function. Thank you Royal Canin for helping my girl enjoy an improved quality of life!

Rated 5 out of 5 by from Great Results! Our vet prescribed this for our puppy with kidney disease. Before putting him on Royal Canin, we were constantly battling with him having accidents in the house and drinking a ton of water. Ever since switching to this food, his kidney levels are stable and his drinking and urination are normal! Thank you!

Rated 5 out of 5 by from Life saving food My dog was put on this food when she was in kidney failure. Her blood work was all out of whack, and I thought she wasn’t going to make it. That was two years ago. She just recently had a yearly appointment and all of her blood work was normal.
