Great tasting!

[This review was collected as part of a promotion.] My vet prescribed this for our dog who has kidney issues and this is the only brand we tried out of about three that she will eat! I am so happy we finally found a dog food my dog will eat.

Great quality that my dog loves

[This review was collected as part of a promotion.] We had to feed this to our dog due to a small infection. We thought it would be a temporary product but after the great results we decided to continue using it.

[This review was collected as part of a promotion.] My dog likes the flavor. And Ian doing well since being changed over to it. I wish the pieces were just a little smaller since my dog is almost 17

Great Product

[This review was collected as part of a promotion.] Our two retired guide dogs, who are almost 14 years old, have been helped greatly by this diet. With renal disease, sometimes our dogs don't feel like eating. This has enough flavor and texture to appeal to them most of the time; they have been able to obtain their weight on the Royal Canin renal support products because they seem to really like them!l

New to the kidney disease

Angus was just diagnosed with early kidney disfunction. Our vet suggested a renal diet, they wanted us to go with Science Diet but due to previous problems with that, I decided to try Royal Canin. When we received our first bag, Angus was licking the bag before I had time to open it. This is a great sign considering how picky he is with his food. I really wished it came in a bigger bag. 17.5 pounds is nothing for a 150 pound Rott!

My dog used to like it more

My 10 year old sheltie has had kidney disease for 3 years now. I have rotated through the various brands of the prescription diets. My dog has always been a picky eater, so she gets tired of them fairly quickly. She used to eat the Royal Canin Renal diet better before they started adding the letters to the title, so I am not sure if the formulation changed at that time or not. I can only find this product at one store in my town and they only carry the 17.5 lb bags. I have wasted a lot of food buying both dry and cans when my dog won't eat it. Now, I have to try and mix it with a non-prescription diet so that she will eat. It's not the best solution, but it's better than her not eating at all.

He loves it!

My dog has chronic renal disease and had to be put on a prescription diet to maintain function. He LOVES his food! He has also maintained a beautiful coat and a fit weight without any problems.
