Product Description

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 at risk of developing lower urinary tract disease and who are predisposed to weight gain
  • Dissolution of pure struvite uroliths
  • Help prevent struvite, calcium oxalate and phosphate uroliths
  • Provides nutrition that aids in the management of pure struvite uroliths
  • Moderate calorie content, compared to URINARY SO , to help maintain ideal weight
  • 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
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals

NOTE: Royal Canin veterinary diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to

Customer Ratings & Reviews

Rated 4.8 out of 5 by 81 reviewers.
Rated 5 out of 5 by Helps control bladder stones in Buddy I love the quick service I get when I order. Buddy does a Lot better with the urinary diet since he has bladder stones. I wish they had a dog treat with the same urinary track benefits. November 21, 2013
Rated 4 out of 5 by Good option for overweight senior dog My 9 year old Corgi has had a bladder stone removed (awful surgery for him). The vet and I tried a few foods before we found Royal Canin Veterinary Diet Urinary SO Moderate Calorie Dry Dog Food. In addition to the bladder stones my dog has a food allergy and is a bit overweight. This food agrees with his stomach and is low-cal. We are satisfied with this food. September 23, 2013
Rated 5 out of 5 by Working so far My vet recommended this food for my 5 year old cockapoo who had crystals in her urine and whose Ph was high at 9.5 (supposed to be 7). She's been on Urinary SO now for about 3 weeks and her Ph has dropped to 8 which is still high, but we're hoping it will drop some more. Also, there are no crystals in her urine now so it's definitely working from that regard. As long as it does what it promises to do (and so far it is), I say it's worth the price and would recommend it. And of course, I always love! Their customer service is world class! No one can touch them on customer service or price. I'm a customer for life! September 12, 2014
Rated 5 out of 5 by Great stuff!! Great "special food" for my "special" pug. My dog had bladder stones removed, and now eats only Royal Canin urinary SO. Need an Rx from pugs MD, but no problems. Chewey does all the work for me. Great product, no more bladder stones! June 25, 2014
Rated 4 out of 5 by This product fills the need My schnauzer was diagnosed having bladder stones and the vet prescribed this dog food I originally purchased the regular formula. After 3 months I started noticing a weight gain. I purchased the moderate calorie formula to see if it will help reduce the weight gain. It's great to have an option. January 28, 2015
Rated 5 out of 5 by Excellent service! Since our dog has to be on the special diet, per the vet, our own vet keeps on screwing up the order every time it is placed, so our alternative was to find a source other than our vet to purchase said product. Chewy has been great, they never screwed our order up and the price is much lower than our vets price which is a win win situation! Thank you for your prompt service and great prices, you've got a customer for life! December 28, 2013
Rated 5 out of 5 by My Sweet Daisy likes it !! This is unusual for my Daisy because she hated the regular kind of the SO food. Now I don't worry so much about her not eating. May 14, 2013
Rated 5 out of 5 by Over all happy with product. Ordering was easy.Price was great. Delivery was exceptionally fast. Will definitely be reordering when it's time. The only challenge was to get my Cavallier King Charles Spaniel Sadie to eat the food. Typically she'll anything but for some reason she did not take to the smell or taste for about the first ten days. I held out and did not go back to her old food for the sake of hopefully improving her urinary health. Now she is fine with the food and eats in the same fashion as before, always looking forward to her next meal. Thanks Chewy! February 18, 2015
