F = Flavorful to help stimulate appetite in dogs and encourage eating with round-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 F for a reason. This highly palatable dry dog food is specially formulated to care for the kidney health of adult dogs under veterinary supervision. “F” stands for Flavorful, and this formula can help stimulate your dog’s appetite. The round-shaped dry kibble can be mixed with other Royal Canin Renal Support formulas, which have a variety of palatable aromas and dry or wet forms 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 feeding this to my kidney disease cat for about 1 year and he loves it.

My dog loves it!

My puppy was diagnosed with kidney failure a couple years ago and was prescribed Royal Canin prescription dog food. We tried another brand and he absolutely hated it. This he loves and cleans his whole bowl! I’m so thankful for this brand and their commitment to quality for our pets. This dog food truly has saved my dog’s life.

My girl really like it!

We tried every kind of kidney support and this one she really liked the taste so I didn’t have to fight her to eat. It’s hard enough l deal with kidney disease and to need to have an unhappy dog makes it all the worse. Thanks for making an edible option for kidney disease patients!

Great food!

This is a great food to buy for your renal pet! My dog got into a bunch of ibuprofen when she was a puppy and went into kidney failure. Luckily, she came back from it, but the Royal Canin Renal food keeps her from possibly having early stages of kidney issues due to this event when she was younger. She loves the taste, and I am happy with her kidney values with being on the diet.

New onset kidney failure

My 12.5 year old German Shepherd has been fed a raw bones/meat, fruits, and vegetable diet since puppyhood. He was diagnosed with chronic renal failure last week and was started on the Royal Canin Renal Support F dry mixed with Royal Canin Renal support can food. When I opened the bag of dry, it had a terrible smell and I never thought my dog would eat it. He surprised me and actually seems to enjoy this food.
