S = Savory to help stimulate appetite in dogs and encourage eating with crescent-shaped kibble

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 phosphorus, and targeted protein levels

Works in conjunction with a variety of appetite-stimulating Royal Canin Renal Support wet and dry dog food varieties

Your vet recommended Royal Canin Renal Support S for a reason. This highly palatable dry dog food is specially formulated to care for the kidney health of adult dogs under veterinary supervision. “S” stands for Savory, and this formula can help stimulate your dog’s appetite. The crescent-shaped dry kibble can be mixed with other Royal Canin Renal Support formulas, which have a variety of palatable aromas and dry or wet forms to help find the right combination to get your dog eating again. And the energy-dense diet provides nutritional support in smaller portions, since dogs with kidney challenges have decreased appetites. Plus, it contains a precise antioxidant complex, fatty acids from fish oil, low phosphorus, and targeted protein levels to help support kidney function.

With over 50 years of scientific research and observation, Royal Canin continues to deliver targeted nutrition to feed every pet’s magnificence. Not satisfied? Then neither are we. Our veterinary exclusive formulas are 100% satisfaction guaranteed. (Just contact us for more details.)

Good food

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 !!

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!

Chihuahua loved it!

My dog wouldn’t eat other name brand foods. She loves this food! Small pieces perfect for her.

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!
