Royal Canin Urinary SO Dry Dog Food
Royal Canin Urinary SO is formulated for dogs with or at risk of developing canine lower urinary tract disease.  It is also used to help dissolve pure struvite uroliths, as well as to prevent struvie, calcium oxalate and calcium phosphate urolithiasis.  Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine and is used to develop a diet that lowers the concentration of ions contributing to struvite and calcium oxalate urolithiasis.  Moderately increased sodium chloride content increases thirst and promotes the formation of dilute urine.  EPA and DHA, long chain omega 3 fatty acids, modulate inflammatory reactions.  A blend of antioxidants helps maintain a healthy immune system and reduce DNA damage associated with cell aging.  Chelated minerals improve digestive and metabolic utilization of trace elements.
