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.

Must Taste Good!

My 13.5 year old Lhasa-Poo has been on the SO Diet for most of her life. She licks her bowl clean every day! AND... our other dog, who is NOT on a special diet, always tries to eat her food before he goes to his! So, it must taste good!

Happy and healthy dog!

This food has literally been a lifesaver for our 4 year old Bichon Ally. She has had 2 previose surgeries for bladder stones. Once her diet was changed to Royal Canine Urinary S/O all tests have come back great! No stones!! Fantastic product!!

Saved a Surgical Procedure

One of my rescues was diagnosed with bladder stones at 8 months. Several were present and the possibility of surgery came up. My vet suggested the urinary diet to gradually dissolve these stones and no surgery. The diet would also prevent new ones. It would take patience on my part but easier on the pup. Well...6 months later her 5 stones were reduced to one the size of a very small pea. She has been on this food since then.

Feeling Royal!

Ginger, my 14 year old Lhasa Apso has been on Royal Canine Urinary S/O for many years due to her frequent bladder infections. She has tried many other brands of dog food and no luck. Until a new veterinarian prescribed Royal Canine brand and it worked! I highly recommend Royal Canine products and so will your Royal Little Friend!

Great and effective!!!

It was prescribed by my vet after my dog had bladder stones surgery four years ago. Being the pampered pooch that she is , my first thought was she won't like it, but she loved it. We have had no reoccurring stones
