For the past 3 weeks, our 12 yr old dog has been going out to urinate much more often than she used to. She squats for a long time to urinate, but nothing comes out. Sometimes a teaspoon of urine comes out. I caught some today and it looks somewhat cloudy. I asked my local vet how much it would cost to diagnose her condition. He said he would need to do an x-ray, urine test & blood test. It would cost $700-$800. My husband & I are both out of work, so we cannot pay this high price for a diagnosis. We love our dog very much & want to help her. I have Augmentin at home. Would it help if I give her 250 mg twice a day for 10 days? I have heard of these additional suppliments: vitamin c, acidophilis, apple cider vinegar & cranberry capsules. Would these be helpful?
