A = Aromatic to help stimulate appetite in dogs and encourage eating with rectangular-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 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.

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!

Trustworthy food for our fur baby!!

My German Shepherd has always had issues with potential renal failure. We discovered this issue with her 10-12 years ago. Our veterinarian suggested Royal Canin Veterinary Diet Canine Renal Support Dry Dog food and wet food, We do her blood work once or twice a year and after putting her on this food her blood work values have improved and have been maintained very well. We started her on this diet about ten years ago and have no doubts about the results. She is now 13 3/4 years old and continues to do very well as a result. We have two German Shepherds and feed them both this tried and proven diet. Wouldn't you do just about anything to keep your best friend healthy and happy. They certainly deserve it and so do you.

My dog Loves this!

My 45 points rescue is over 15 years old and is a very picky eater. We tried other brands of prescription food, but she wouldn't eat it. This is her 4th bag of Royal Canin and she still loves it. It is no longer a struggle to get her to eat. Thank you, Royal Canin!

He is full of energy and is keeping at a perfect weight. He is so enthused when I put his food in his dish. Gobbles it down immediately. No picky eater .

The Best Dog Food EVER!!!

Our vet prescribed this food for our three senior dogs and I have to admit I was skeptical. However, the difference in my dogs was almost immediate! I truly believe that your food is a large part of the reason our senior dogs are still with us. Their health improved almost immediately and they are all three doing very well. Only one has to take any medicine for their kidneys. I tell everyone I meet about your wonderful food and the difference it has made for our precious furry family members. Thank you for a wonderful product!!

poor taste

My dog refuses to eat this or to eat the canned Royal Canin renal diet wet food (we tried the lamb & two formulas of the chicken)

Tastes Great

My 17 year old puppy has the beginning stages of chronic kidney disease and our vet put him on this diet for renal support. Sammy James transitioned well and loves the food.
