Helping cats and dogs live their healthiest lives.

Customized palatability profile designed for individual preferences.

Your vet recommended Royal Canin Renal Support A for a reason. This highly palatable dry dog food is specially formulated to care for the kidney health of adult dogs under veterinary supervision. “A” stands for Aromatic, and this formula can help stimulate your dog’s appetite. The rectangular-shaped dry kibble can be mixed with other Royal Canin Renal Support formulas, which have a variety of palatable aromas and textures 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.

I have been using Canine Renal Support dry dog food for my yorkie for almost 2 years after she was diagnosed with renal failure. My vet was not sure my yorkie would survive. Her renal function was almost normal the last checkup.

Flavors my dog actually likes

Starting using this product six months ago when my dog was diagnosed with kidney failure. Here we are six months later with diet being the only major change and my pup is doing well. Thank you Royal Canin

Has helped tremendously!

I had been using science diet, but when I went to order the food i usually bought and checked the recall list and it was on it I decided to move on. I have a small rescue that has early renal failure. She loves the food and has made a huge difference in her blood work and check ups.

Great renal support for my girl

My furgirl had elevated kidney levels and hadn’t gained any weight since she turned 2 yrs old. As the Vet suggested Since her levels were only slightly elevated we should support her kidney function with the renal support Royal Canin dog food..I trust my vet and love the fact this food brought her kidney levels back to normal plus she gained 5 pounds and now looks like a healthy 5 yr old perfect girl!! Thanks Royal Canin!!

Great food for my sick dog

I’ve been buying this food for my 14 yr old husky for about a year. He was diagnosed with kidney failure 15 months ago. I tried other prescription kidney diet food and he just didn’t seem to like it. He’s very picky and I’ve found that he likes this food. At this point his quality of life is still pretty good and he’s a happy boy, so we are trying to slow down the progression of his kidney failure with diet and medication. Although I’m on a very tight budget because I’m disabled, I will continue to get him this food as long as he needs it. Any coupons, discounts, samples would be greatly appreciated.

Works Great!

My MiniatureSchnauzer got a very bad infection in one of her kidneys from a stint that was put in 2 1/2 years ago because of a kidney stone blockage. She had to have that kidney removed a year and 2 months ago. She was put on Renal A Royal Canin and she is doing really well. I am so thankful that you have a good that will help my sweet girl stay well. Maggie says thank you to!

My dog loves this food

When I had to start purchasing prescription dog food I was very worried. I had heard that it was overpriced, most dogs didn't want to eat it and that it wasn't worth it. My dog not only enjoys this food but gets excited every time I bring a new bag home. He knows that it is HIS food. I chose Royal Canin because of their reasonable prices, and great reviews. I'm happy to report that my dog is still healthy and living large.

Best of the 3 flavors

My vet prescribed a renal diet for my 16 year old poodle whose heart meds are stressing his kidneys. Tried the other 2 varieties--S and F--and my dogs would only eat enough to stave off starvation. (Sometimes the younger dog would just push the bowl around in a gesture of disgust.) Then I switched to A and I no longer have any problem with them eating the kibble. They clean their bowls every night. Furthermore, my elderly poodle seems to have more energy and to be more active than before, so I think he must be feeling quite a bit better. Sometimes he's downright frisky!
