Lower urinary tract disease (LUTD) refers to a group of disorders that commonly leads to irritation of the urinary tract and corresponding undesirable clinical signs.

What causes Lower Urinary Tract Disease? In dogs, bacterial infections of the urinary tract and the presence of stones (uroliths) in the urinary tract are the most common causes. This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Key Benefits

  • Recommended for dogs under 22 lbs at risk of developing lower urinary tract disease
  • Dissolution of pure struvite uroliths
  • Help prevent struvite, calcium oxalate and phosphate uroliths
  • Provides nutrition that aids in the management of pure struvite uroliths
  • Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis
  • Contains nutrients to support healthy teeth
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals

Rated 5 out of 5 by Suits my dogs medical needs My Dr. Put my dog on this regimine because of bladder stones caused by eating protein. He loves the food. August 21, 2016
Rated 5 out of 5 by Product works as prescribed This was recommended by my vet due to a urinary infection my dog has. So far so good. Just wish coupons were available due to cost. Will probably continue to use for the rest of my dogs life. August 18, 2016
Rated 5 out of 5 by good product our dog loves this food- she has to have it for her diet- forever- - glad she likes it..... most of our other pets knew that is was a presription food- didn't like it as well- but this dog thinks that it is great August 9, 2016
Rated 5 out of 5 by My dogs love both the dry and the wet food I was very worried that my dog would not like the new special food to counteract her propensity for kidney stones. However she loves it and as I have been adding it gradually , she has had no gastrointestinal problems at all. My other dog has no need for the Royal Canin Urinary SO but she loves it also so I mix it with her regular food. I highly recommend this product. August 3, 2016
Rated 5 out of 5 by Dog appreciation My dog seems to genuinely enjoy this product. He generally will pick around the dry food to get at whatever it is mixed with. July 13, 2016
Rated 5 out of 5 by dog food the dog food is very good. my yorkie loves it and i will order some more. June 18, 2016
Rated 5 out of 5 by Seems to be an effective product, but a little pricey. Would be great if it came in a larger quantity. Product was Vet-prescribed for my seven year old yorkie-poo that had recurring urinary tract infections and crystals in her bladder. Seems to have helped to reduce the apparent discomfort she had when urinating and the frequency. She's had only one mild infection in the two years she's been on the food which I count as progress, especially considering the high concentration of dogs in the area where we live. Frustrating that the food isn't available in a larger quantity as the small 8.8 lb. bag goes pretty quickly. Must have a pretty agreeable taste though as my yokie-poo eats it without much hesitation and my minature schnauzer prefers it to his Wellness food. April 30, 2016
Rated 5 out of 5 by Perfect for My Buddy Buddy, a little, white Havanese, developed bladder stones, resulting in a $2,700 surgery. Since then, about 5 years ago he had eaten nothing but RC Urinary SO and had been healthy since. May 6, 2016
