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
