Saved my dog's life!

[This review was collected as part of a promotion.] My ESS was diagnosed with renal failure one year ago and per the vet has eaten nothing but this food since. His values have improved, overall he has stabilized and he loves it. Now, Vet says he will live a normal life span. THANK YOU!!!

I think you need to spell out what "S" is or "A" i

[This review was collected as part of a promotion.] I like the renal dry food, but need to spell out what "A, F, or S" means on the label.

My Dog Loved It!

[This review was collected as part of a promotion.] My dog progressed from early kidney disease to late stage disease prior to his death. Other brands of dog food he turned away from, but he always ate Renal S, and loved it. I knew it was an exceptional quality food and was beneficial to his health. I was comforted to know that he was enjoying his food until the end.

My 15 year old dog LOVE IT !!!!

[This review was collected as part of a promotion.] My 15 year old miniature poodle has been on this diet for over 2 years now. Not only does he LOVE it, but has not allowed his kidney disease progressed. I would highly recommend this diet.

Highly recommended!

[This review was collected as part of a promotion.] I’ve been using this dog food for three years now. My Rescue lab mix will be six in February. He started frequently having to go out to urinate and we took him to the vet. He was diagnosed with kidney and liver failure. My Vet narrowed it down to- due to chewing on a stick that had bird feces on it. The vet prescribed Royal Canaan dog food for his special diet. I believe it saved his life.

Life saving food

[This review was collected as part of a promotion.] My dog was put on this food when she was in kidney failure. Her blood work was all out of whack, and I thought she wasn’t going to make it. That was two years ago. She just recently had a yearly appointment and all of her blood work was normal.

Very tasty

[This review was collected as part of a promotion.] My border collie Lori was diagnosed with protein losing nephropathy over two years ago and and given a very poor prognosis she is doing great with most everything. I attribute her longevity to the few medications and her diet . She eats exclusively Royal canin renal. Thanks for providing her such a great diet that she loves.

Likes it

[This review was collected as part of a promotion.] My 4 year old Great Pyrenees has kidney disease. Feeding time can be difficult as this disease affects his appetite. He seems to like this dry food more than other kinds.
