Helps stimulate appetite in dogs and encourage eating with aromatic kibble

Helps reduce the risk of skin and GI reactions with proteins that are broken down to a size that’s less likely to be recognized by the immune system

Helps compensate for decreased appetite with a highly palatable energy-dense formula to reduce meal volume

Helps promote kidney function with a precise antioxidant complex, fatty acids from fish oil, low phosphorous, and target protein levels

Your vet recommended Royal Canin Renal Support + Hydrolyzed Protein for a reason. This highly palatable dry dog food is specially formulated to care for the kidney health of adult dogs under veterinary supervision. The aromatic dry kibble stimulates your dog’s appetite and encourages eating. Hydrolyzed proteins, composed of low-molecular-weight peptides, help minimize the risk of a reaction due to a food sensitivity while also helping support kidney health. And the energy-dense diets provide nutritional support in smaller portions, since dogs with kidney challenges have decreased appetites. Plus, they contain a precise antioxidant complex, fatty acids from fish oil, low phosphorous, and targeted protein levels to help support kidney function.

Great for kidney issues.. and spoiled, picky pups!

My dog was diagnosed with Kidney disease and the vet suggested Royal Canine Multifunctional Renal Support. Lucy is very spoiled and very picky. Give her the same dry for a few weeks and she's bored and not eating. She has been on this for about 6 months and she's still happy to see it. And I have seen a great change her in stools. Low protein, low salt, highly recommended by dog and owner!

Excellent food for a health dog!

My dogs have been eating this for several years now, and it has helped resolve all the health issues they had before being on this diet. We use the renal part for crystals in the urine and the hydrolyzed protein for constant paw licking, which both resolved with this food.

Great product!

My 12yo mutt is allergic to EVERYTHING & has now developed kidney disease, Royal Canin is the ONLY brand that makes this combination so we don't have to choose whether to make him less itchy or help his kidneys. It has worked wonders for him, desease has slowed since we started this recipe about 1yr ago. It does make him constipated but a little ground pumpkin does the trick for him. Love Love Love this food & manufacturer!!

Where can I purchase this food?

Hi, if anyone can tell me where to purchase this food besides amazon that would be great! I have trouble finding this food and my dog really needs it right now!

Great for Health & Taste!

My dog has been on this food for more than a year and not only does it support his renal health needs, it also provides a hydrolyzed protein that is easily digested for him. Believe me.... it is not easy to get this combination in a dry dog food that your dog will love, and that makes you feel good providing a healthy diet for him! Happy dog.... happy owner!

We started this food close to one year ago after finding early kidney disease in our dog. She was getting us up 2-3 times per night to go to the bathroom and drink more water. After starting this food she was sleeping through the night with no problem. She 15+ years old now and showing minimal signs of slowing down - thank you!

Great for my allergic dog with kidney issues

We had to switch to this multi-function renal support + hydrolyzed protein dry dog food after seeing some severe rashes that my 15 year old Retriever/Spaniel/Chow dog developed from eating the regular renal support dry dog food. The support technician was very helpful in finding an alternative which has chicken fat instead of chicken by-product.

Works great

This is the only food my bulldog is able to eat without having an allergy. It has been working great for the last couple years.

Great Option

I bought this food for my 14.5 year old dog who both has CKD, but also chicken and corn allergies. He was super happy with the new choice and did well on it!

Great to hear that he has done so well!

Dog loves it!

My dog is allergic to everything. She does extremely well on this diet and is actively excited to eat it, unlike some other diets I have tried. Her kidney values are stable as well. Very happy with this diet!
