Hills U/D available from VioVet

Hill's Prescription Diet Canine u/d has been developed for dogs suffering with Urolithiasis (mineral stones in the urinary tract). This condition is marked by a variety of unpleasant symptoms, including difficulty with urination, frequent urination, bloody urination and a painful abdomen. Following surgery to remove the troublesome mineral stones, dogs are most often provided a nutrition plan to help reduce the risk of Urolithiasis recurrence. Hill's Prescription Diet u/d has been specially formulated to aid in the management of dogs with this complaint, as well as dogs suffering with advanced renal disease due to the formulation's low mineral content.
