The vet recommended a urinalysis and culture after the end of 1 week, 2 weeks, and 3 weeks. I'm not sure we're going to do all of that, as these tests are really expensive. The most important one is the test after the end of 3 weeks to make sure it's all cleared up. We might do one at the end of 1 week just to make sure the treatment is working and then at the end of 3 weeks. The vet gave us a urine cup and a collecting tray. It looks like a tray that you get french fries in. We'll also need to get some blood work done to make sure that it's not a kidney infection.
