HELPS DISSOLVE STONES: Innovative urinary tract dog food helps dissolve pure struvite stones and helps prevent calcium oxalate stones

BLADDER HEALTH: Lowers the risk of crystal formation using RSS methodology for dog bladder health

S/O INDEX: The exclusive S/O Index creates an environment unfavorable to crystal formation in the bladder to support urinary health

SPECIALIZED KIBBLE: Adapted kibble size for small dogs encourages chewing to help reduce tartar buildup

When your small dog has big urinary issues, easing their discomfort requires special care. But with the help of your veterinarian and Royal Canin, there’s not just hope—there can be a true difference.

This veterinary-exclusive dry dog food was developed to nutritionally support your small dog’s urinary tract and bladder health. It increases the amount of urine your dog produces to help dilute excess minerals that can cause crystals and stones. Low Relative Super Saturation (RSS) methodology is used to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. And for dental health, the adapted kibble size for small dogs encourages chewing to help reduce tartar buildup. Lower urinary tract issues may be a recurring concern for some dogs. Talk to your veterinarian about keeping your dog on this urinary dog food for long-term urinary support. And ask them about the right Royal Canin treats to complement your dog’s diet.

The Best “Royal Canine”

Our little shiz a poo, Pepsi, had 2 surgeries for bladder stones. Almost lost her before the 2nd surgery. Our vet did a thorough search to see what was out there to prevent these stones. Your company came through with the special food. We’ve had no problem since 2013. We do have her urine tested every couple of months to be safe. We take the canned food and cut into small bits, bake them, and she has her “cookies” for a treat. Thank you Royal Canine!

Canon urinary s/o small dog

On the recommendation of our vet, we had to switch to a food that would help our dog not get urinary tract infections or kidney stones. We have had him on this food for about nine months. He loves it and has not had any issues so far.

My dogs won't eat this

Vet prescribed this and my dog just hates it. Even mixed with regular rice/carrots/chicken. Now I'm stuck with a 45.00 expense.

The dry food is the perfect size for a small dog.

We have been feeding this to our Lhasa Apso for four years and have not had a single urinary issue. Will continue to use very happy with the results. Also his coat is very healthy.

No more Kidney /Bladder Stones

My 3 yr old Paisley ( Shih-Pooh) has been on this food ever since shes was 12 weeks old because she had some Kidney/ Bladder stones. My vet put her on this food which she loved from the get go. She is still on this wonderful food & gets checked for stones every few months & hasn`t had any more stones. This food is good to crystalize the stones which is easier for her to pass!! She loves this food & Im planning on keeping her on it the rest of her life. It is alot cheaper to buy this food than have the surgery for kidney stones.
