If it were me, I'd grab a urine sample and just drop it off at the counter at your vet. You really don't have to make an appointment since they can run tests on it. Just make sure the folks know what the symptoms are at this point. They will be able to run tests and let you know. Asher dribbled too and still does occasionally when he gets too excited (which is often thanks to Samson).
Oh, one thing I did forget to mention. I was convinced, I have no proof, that Ashers high protein food was causing the UTI. I had him on Orijen puppy but after reading about high protein foods being too much for some puppies, I took him off and put him on ToTW Salmon. It has 26% protein. He was on Orijen for about 3 weeks. What are you feeding your guy?
