Whether this is your dog’s first urinary issue or they need ongoing urinary care, your vet recommended Royal Canin Urinary SO Aging 7+ for a reason. This veterinary exclusive wet dog food was developed to nutritionally support your senior dog’s urinary tract and bladder health. This formula is designed with Relative Super Saturation (RSS) methodology to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. It also features an exclusive blend of nutrients and antioxidants to support cognition and vitality in senior dogs, and a highly palatable texture to stimulate a decreased appetite and encourage regular eating.
