Relative Supersaturation (RSS) methodology predicts the crystallization potential of urine. RSS is used to develop diets for dogs prone to both struvite and oxalate urolithiasis.

Hydrolyzed protein, composed of low molecular weight peptides, is highly digestible and minimizes signs associated with food sensitivities.

Specially formulated to assist in the management of struvite and calcium oxalate crystals and stones and adverse food reactions in the canine patient.
