Royal Canin Veterinary Diet® Canine Renal Support S dry dog food

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.

  • 3 dry and 3 wet options for both cats and dogs providing 9 different feeding combinations
  • All RENAL products have similar nutritional profiles, easing the transition when introducing product rotations without concern for digestive upset
  • Click here to view feeding combinations based on the dry options A, S, F and wet options E,T,D

Renal Support S dry is a high energy and highly digestible diet for dogs that has been formulated with low protein and low phosphorus levels and is intended for intermittent or supplemental feeding only.

Rated 5 out of 5 by from Dog loves it My dog had slowed his eating and was refusing the food I had that was another renal formula. The vet recommend I try Renal Support S and he loves it! He is eating normally again and I am no longer worried about him giving up.

Rated 5 out of 5 by from Reliable nutrition for renal issues My doctor prescribed this food after my Jack Russell was bit by a spider. He has been eating Royal Canin for quite a few years now and loves it! He is 12 and still has the energy of a 6 year old.

Rated 5 out of 5 by from Extremely palatable!! My sheltie Toby was diagnosed with the early stages of renal failure. I switched him from his regular food and to my delight he LOVES this food. Usually prescription diets aren't really what our pets have in mind but he likes this even more than his old food. Thank you Royal Canin. One less thing I have to worry about :-)
