Product Description

Royal Canin Veterinary Diet Urinary SO Canned Dog Food is a complete and balanced diet for adult dogs formulated to aid in the nutritional management of calcium oxalate and struvite urolithiasis. It is designed to support struvite dissolution and urinary health, and will also increase your dog's urine volume to help decrease struvite and calcium oxalate levels.

Key Benefits

  • 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
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals
  • Reduced level of magnesium, a natural component of struvite stones
  • Complete and balanced nutrition

Customer Ratings & Reviews

Rated 4.8 out of 5 by 148 reviewers.
Rated 5 out of 5 by Royal Canin Urinary 20 "PHENOMENAL Dog Food" Absolutely a gift from heaven for Sarah my 9YR old Female Bichon. Sarah is a real stone maker. No good. The vet just removed more stones than I woud like to see. He put her on the wet food and she absolutely loves it. She doesn't look for people food. She was on Orijon 6 fish dry and she liked that, but not like the urinary SO. Hopefully this willl be the answer to my prayers. Now I am looking for the recipe for treats that can be made out of the canned food. Anyone have a recipe. If so I would love to have it. Could you post it online? October 4, 2012
Rated 5 out of 5 by Amazing results for bladder stones! My sweet Shih-Tzu Teddie recently had her second surgery within the last year--each time removing over 130 bladder stones. She has suffered with this ailment her entire six years. I was a my wit's end and did not know what I was going to do and prayed for a solution to prevent this from occurring again. We tried another prescription dog food first with no results. Then my vet recommended we feed her Royal Canin Urinary So canned food. I am thrilled beyond words to say that as the vet checked her urine last week there were no crystals forming! I thank God and Royal Canin for this unique and effective formula that hopefully will keep Teddie healthy and happy throughout the rest of her life! March 10, 2012
Rated 5 out of 5 by Great Prescription Canine Food Our LH Dachshund has Cushings disease' as well as, bladder stones. our vet prescribed Urinary SO, "wet" and/or "dry".. We use and buy both at chewys. At our vets suggestion, my hubby makes "Daisy cookies" using the canned food. He makes little "cookies", baking them into tasty morsels, according to our little "girl".. She loves them! Chewys" is very price competitive, as well as, offering free or decreased shipping charges. Chewys is our canine online favorite! January 14, 2013
Rated 5 out of 5 by Best Customer Service The customer service I received when I purchased this product is the standout, rather than the food itself. I bought two cases of the product and then my pup stopped eating it after a few feedings. I had a case and 3/4 left over that she refused to eat. I had my doubts about the 100% satisfaction guaranteed returns, but went above & beyond. After I explained the issue, they refunded my money and had me donate the food rather than return it to them. Awesome service and a company that truly stands by its 100% satisfaction guarantee. I told everyone I know that has pets about my experience, and I'll be purchasing from more items from in the future with no hesitation. Thanks Chewy! December 30, 2012
Rated 5 out of 5 by Easy to use and my dog enjoys eating it. After several surgeries for bladder stones, my male bichon frise was put on royal canine so for urinary tract problems. He has been on it for 7 years and bladder stone free ever since. HE has a can a day and the dry for his treats. Thanks so much for making my guys life longer and pain free. August 2, 2012
Rated 5 out of 5 by My dog loves this food My dog loves this food. My poodle has kidney stones and the vet prescibed this food. We tried several other formulas, but she likes the Royal Canin Veterinary Diet Urinary SO cans. February 10, 2013
Rated 5 out of 5 by Hogan loves it. He never liked canned food until this product.I slice it and roast it in the oven,he thinks it's a treat.Very happy. April 13, 2012
Rated 5 out of 5 by My dog, Bella loves this food! Royal Canin was highly recommended by a Nutrition Specialist at the NC State University Vet School. This is the only thing I feed my Bella!!! The nutritionist also recommended pouring warm water over the food to add even more water to the diet and Bella thinks the water is gravy!! Laps it up! So far, no more bladder stones!!
