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
  • 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
  • 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

Rated 4.7 out of 5 by 359 reviewers.
Rated 5 out of 5 by Life saver for my St. Bernard Puppy My (at the time 6 month old) St. Bernard female was having recurring uti's. As soon as she would get one she was on antibiotics and then two days after the medicine was done the uti would be back. I was going crazy with the "dripping" in the house as she was totally potty trained. Vet did an xray of tummy to rule out other issues and she was clear. Recommended this food, WOW, she is now 14 months old and not a single uti!!! August 24, 2016
Rated 5 out of 5 by Dogs love it! This was recommended by by vet to help with weight loss. He actually gets more at each meal than his prior food but there isn't as much fat. The service and timeliness of delivery with Chewy as also been outstanding, glad I found them! August 24, 2016
Rated 5 out of 5 by PRESCRIPTION DOG FOOD My dog will eat prescription dog food for the rest of her life. I have to get a prescription from our vet in order to purchase it. The large bags are heavy and the office is inconvenient. I decided to purchase from and what a pleasure! This large bag was delivered to my door and I have automatic reorders. This is a huge help to my busy schedule! August 20, 2016
Rated 4 out of 5 by Shih tzu is hooked My dog goes crazy for this food and this means a lot since he is a really picky eater. He has been on this food for a couple months so I am not too sure about it's effect yet on his annual recurring bladder infections and struvite crystals. For now the combination of this food plus the antibiotics has got rid of the infection and have not had any visible symptoms of struvite crystals. August 18, 2016

Rated 5 out of 5 by Great food I was worried that the new food our dog was prescribed would not be tasty. He definitely likes it eats this better than what we fed him before. Even when he wasn't feeling good and after surgery. August 13, 2016
Rated 5 out of 5 by Does well for our old schnauzer with bladder stones. She loves it and it is easy to maintain her weight. Does well for our old schnauzer with bladder stones. She loves it and it is easy to maintain her weight. The price is right and the nutrition keeps her healthy and away from the vet. Good scans and no more bloody urine! August 8, 2016
