Helps dissolve and prevent pure struvite stones and helps prevent calcium oxalate stones

Lowers the risk of crystal and stone formation using RSS methodology for bladder health

Satisfies hunger and reduces begging behavior by helping make dogs feel full

Highly palatable dry kibble can be mixed with Urinary SO + Satiety wet dog food for additional variety

Whether this is your dog’s first urinary issue or he needs ongoing urinary care while on a weight loss plan, your vet recommended Royal Canin Urinary SO + Satiety for a reason. This veterinary-exclusive dry dog food was developed to nutritionally support your adult dog’s urinary tract and bladder health. The complete and balanced formula promotes satiety—meaning it provides a feeling of satisfaction, so your dog feels full in between meals and is less likely to beg. It’s designed with Relative SuperSaturation (RSS) methodology 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. Talk to your veterinarian about keeping your dog on this urinary dog food for long-term urinary tract support and weight management. And ask them about Royal Canin Urinary SO + Satiety wet dog food and Royal Canin therapeutic treats to complement your dog’s diet or for mixed feeding.

Keeps my dog healthy

I've been feeding this to my border collie for several years after a serious UTI with crystals in her urine. She has has been crystal free with no UTI's since. I highly recommend this dog food for any dog that has frequent UTI's.

My fur baby loves it

My vet put my baby on this food 2 years ago and it has performed perfectly. She has never felt better.

A few years ago, my 7 year old Shiba decided that Thanksgiving day would be a great day for a UTI. The emergency vet (pronounced 'really really expensive vet') fixed her up for the day, but recommended that I go for additional testing at her regular vet. Lo and behold, little Roxy was predisposed to crystals in her bladder. No good. Our vet prescribed the regular old Urinary SO food, which completely and absolutely cut out the UTIs and crystals. However, after Roxy got to be a bit chubby later on, we learned that part of its effectiveness at reducing crystals was due to its high fat content. Enter: this food. I will stick to the short version here. 0 UTIs, and a leaner, meaner shibe. My only complaint is that this food is veryyyyy expensive.
