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 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
Rated 5 out of 5 by great treat Dog loves the product which is a great plus. He has no teeth but has no problem with chewing the bites. Will order more. May 1, 2016
Rated 5 out of 5 by Bladder stone prevention This product was recommended by my vet to help my malty-poo's system prevent bladder stones from forming. It seems to be working -- I have had 2 x- rays on her since she has been eating this food and since she had bladder surgery 8 months ago to remove two stones and so far she has not formed any more stones. I hope this continues.It is a prescription order, but once I provided the prescription to Chewy from my vet, I can continue ordering without contacting my vet every time I need another bag of this food. April 11, 2016
Rated 5 out of 5 by Good price and speedy delivery. The products I purchased are prescription foods. The royal cannon has kept studevite stones from forming in my pugs bladder. There for I would highly recommend this for dogs that are prone to bladder stones. And overall I was very satisfied with April 25, 2016
Rated 5 out of 5 by Works well for kidney crystals and stones I have been using this product for only a few months now to combat crystals in my dog's urine. It has helped to dramatically reduce the crystals in just a couple months. The crystals will turn into kidney stones. I have a Bishon and evidently they are prone to kidney stones. I will use this product as long as it helps to keep my dog healthy. For those of you that have a white dog like me, I have always had issues with tear and saliva stains. When I first started using this food it got worse. And then after a couple months the stains completely went away. I'm very happy that both issues are so much better. So far I highly recommend this food. March 4, 2016
