Customized palatability profile designed for individual preferences.

Cats and dogs with CKD can often have waxing and waning appetites. Since pets rely on more than just taste when determining what they will eat, ROYAL CANIN® RENAL SUPPORT diets include several aromatic profiles along with kibble texture, shape and size that can help stimulate decreased appetites. Available in multiple aromatic profiles, in both wet and dry food, the diets can be easily mixed or rotated to provide multiple feeding options.

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!

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!

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.

Saved my dog's life!

My ESS was diagnosed with renal failure one year ago and per the vet has eaten nothing but this food since. His values have improved, overall he has stabilized and he loves it. Now, Vet says he will live a normal life span. THANK YOU!!!

I like the renal dry food, but need to spell out what "A, F, or S" means on the label.
