Good food

[This review was collected as part of a promotion.] My dog was originally on k/d and loved it but gained a lot of wait while on the diet. I switched to Royal canin and he has been steady with his weight and his kidney enzymes are still doing well. Only reason I didn’t give 5 stars is because the largest bag size is 17.6 pounds. I do like that the renal diet comes in different kibble shapes, etc.

My Golden Girl likes it !!

[This review was collected as part of a promotion.] 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!

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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.
