BENEFITS: STRUVITE DISSOLUTION -Provides nutrition that aids in the management of pure struvite uroliths. MODERATE CALORIE -Moderate calorie content, 11% less than Canine Urinary SO dry, to help maintain ideal weight. URINE DILUTION -Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals. LOW RSS -Relative Supersaturation (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. S/O INDEX -This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.
