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

Rated 4.7 out of 5 by 370 reviewers.
Rated 3 out of 5 by A necessary evil. After my 35 day pregnant dachshund had to have bladder surgery to remove a large struvite bladder stone, my vet said she HAD to have this special food, or she'd be back for another bladder stone removal. So I ordered it. This stuff has no real meat in it, it is yellow in color and she is eating it like she is starved. It DOES do what it claims to....makes her urinate(profusely). I'll feed her this bagful, but in the meantime, I'm looking for a diet alternative that will give her good bladder function AND some decent ingredients. September 23, 2016

Rated 5 out of 5 by My fussy eater loves the food My shis tzu ( fur baby) had a large bladder stone removed 3 weeks ago. Dr. has her on this for the rest of her life. Now, Lila is the fussiest of eaters. I was worried that she would not eat the food. LOVES IT!!!!! Also, it is really the only food her Dr want her to have so , since I have the dry food, I also give her a few pieces as her treats. I also have a Doxie but I have her on the regular food and she loves a few pieces as a treat as well. So happy with this brand!!!! September 17, 2016
