My 12.5 year old pug, Zoe has had bladder cancer over 2 years now. I started giving her the Nuvet wafers a year ago due to her getting infections on her bladder which caused her too pee blood. She has not had an infection since taking The Nuvet. It has also stopped my lab from having itchy skin. Overall I feel the Nuvet has helped in the longevity of Zoe's life. My girls love the wafers and it is affordable, 90 wafers for 50.00, one a day.
