About Royal Canin Kidney Health for Dogs

Concerned about Your Dog’s Kidney Health?

The healthy functioning of your dog’s kidneys is essential to them living a healthy life. Their kidneys serve as a filtering system that helps remove toxins and waste from blood. You should always work with your veterinarian to monitor your dog’s kidney health.

Support Your Dog’s Quality of Life Through Kidney Health Challenges

Feed a Specific Renal Diet

Your veterinarian can recommend the right diet to support your dog’s kidney function.

Encourage Drinking Water

Make sure that your dog always has fresh and clean water available. Offering them moist food can also support hydration.

Stimulate Your Dog’s Appetite

Offer your dog a nutritional option with different taste, smell, and texture to help ensure food intake, especially for pets with a poor appetite.

How Nutrition Can Help

Your veterinarian may recommend a formula that includes:


Featuring EPA + DHA long-chain omega-3 fatty acids to help support renal function.

Antioxidant Complex

Enriched with a blend of antioxidants to promote tissue and cellular health.

Kidney Support

Formulated with low phosphorus and high-quality restricted protein to support renal function, helping to improve quality of life.

Adapted Energy

Adapted energy content to reduce meal volume and help compensate for a decreased appetite.

Add Variety and Remember to Set Autoship

Offering a range of aromas, taste and textures can help ensure palatability and adequate food intake. Also, remember to set Autoship to make sure that your dog always has their veterinarian’s recommended nutrition.

Questions & Answers

7 Customer Questions

What is the percentage of sodium, carbohydrates, calcium, and what type(s) of protein are included, as well as the percentage of each?
Answer by ChewyJul 18, 2019
The sodium content is 0.35% and the calcium content is 0.4%. The protein source is vegetable using corn gluten and wheat gluten. Royal Canin does not report the percentage of each individual protein as that is proprietary and part of recipe. However the total protein content is 14%.

How many cups of food are contained in each size of bag? I'm trying to calculate the most appropriate size to buy.
Answer by ChewyApr 30, 2019
There will be approximately 4 cups of kibble per pound. The 6 pound bag will have close to 24 cups and the 17.6 pound bag close to 70.4 cups.

What is the size of the kibble?
Answer by ChewySep 22, 2022
It is a square kibble the size of a chocolate M&M.

what is the Phosphorus % as fed , and dry matter basis?
Answer by ChewyAug 23, 2022
The Renal Support A Dry Dog Food contains approximately 0.19% phosphorus on an as-fed basis (approximately 0.21% phosphorus on a dry matter basis).

Life Changing

We though our older dog had incontinence as he started having accidents even after recently being taken outside and could no longer make it through the night without being taken out. He was diagnosed with kidney disease and after a few days on this food he was acting like he was years younger again. The accidents no longer occurred and he showed more energy and contentment. It's been 18 months and he's still doing great.

My Dog Loves it

I ordered this renal kibble after my 5 yr old American Eskimo was diagnosed with mild kidney disorder. He seems to really love it. I supplement it with a wet renal support prescription dog food.

Dogs love it!

When our pup had to put on a special Renal support diet, we were provided a few brands by our veterinarian. We chose to try Royal Canin "A" and our pup absolutely loves it. We have two Miniature Schnauzers, ages 1 year and 7 years. I asked our vet if ok for the older dog to eat it also and was advised it's ok which is great because both dogs love it and would fight over it. This is the only food we purchase now and am completely satisfied. Thank you Chewy for the fast delivery.

pooch not loving it

Little pooch doesn’t love this food. At first we thought she was taking a turn for the worst, but if you attempt to feed her anything else she is anxiously awaiting it. She wont even really eat this if you put peanut butter on it. Moved to the canned food though and surprisingly if you mash the loaf in with the kibble, she will generally eat both now! We were supplementing with early consult because that’s all we could get at the time and I’m anxious to see how the non-early consult wet food goes over. Does make dogs breath smell like cold wendy’s fries you left in the car- the cans do not.

First food order

This is the first time I have ordered food from Chewy. It was easy to place an order and convienent to have it delivered to my house in just a few days. Joy is on a renal diet and they took care of getting a prescription from my vet's office. Best of all, it was the lowest priced I found.

My dog has never been picky and is a virtual garbage disposal. His dog food has always been dry and it has always been eaten. Unfortunately 2 weeks ago his vet discovered renal issues. She gave me a few cans of renal food until I could order dry. He gobbled the canned food. Unfortunately he has an aversion to this dry food and refused to eat very much. I quickly ordered the canned and mixed the two. Which he is happy to consume.

Chewy is always amazing. My chihuahua will only eat large dog kibble and as he is a senior now (at age 9), this blend is his only food.

picky eater loves this food

My dog recently got switched to this diet for health reasons. Was scared that he would not like it. He acts like it is a treat and love to have this food. Properly mixed with the old stuff we were able to switch him over 100%.
