We had no experience with UTI's in dogs until our Boxer had one. I wish I would have checked her earlier because the reason I notice was I watched her urinate and there was blood in it
I agree with Chachi it's very simple they will just test the urine and should be able to tell. If its not a UTI maybe it's all the holiday commotion causing it? Georgie tends to have "accidents" when things are out of sorts.
