Provides nutrition that aids in the management of pure struvite uroliths.

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.

Increasing the urine volume reduces the saturation of urine with calcium oxalate and struvite crystals.

Contains nutrients to support healthy teeth.

Specially formulated to assist in the management of struvite and calcium oxalate crystals and stones in small breed dogs (less than 10 kg).

Great Food

[This review was collected as part of a promotion.] My little dogs love the prescription urinary so as they have had bladder stones and one of them it has been used as preventative and has work great. I also use the canned version with the dry but they love this food and wished I could buy it for my big dogs but due to the cost I am unable to afford it for them as well since my Newfie eats 5 cups of food a day.
