I've noticed over the past couple of days that every so often I would have some water on my floor, not puddles but fairly small "drops". Well last night Chloe got off the couch and I noticed a few drops from where she was laying. It's not enough for me to tell if it is urine or water, but I'm pretty sure it's urine. Could this indicate a UTI? We have a doggy door so I can't tell if she has been going frequently or not, most of the time it looks like she's just going out to play. Do you think I should go ahead and take her to the vet or wait it out. This is my first female dog so I'm unsure about some of the symptoms, my second thought was maybe discharge?
