Our 8 year old Bullmastiff has had regular Bladder Infections for the last 5 years. Most recently she has been on Antibiotics from our vet anywhere from 2 weeks to 1 month at a time. Each time she get her infection back usually as soon as a couple of weeks after finishing her pills. This time we were told her infection was back and to start her up again, and we decided it was time to try another alternative. I am hoping and praying that the Apple Cider Vinnegar works for our Blanche as we are concerned about so many antibiotics in her system. I am mixing 2 tablespoons of ACV with 2 tablespoons of yougart 3 times a day to start. She is a big dog about 117 lbs so I increased it a little. I will let you all know what her outcome is as soon as I see any changes.
