Enzo has been licking his lips a lot lately. Not constantly, but enough that I notice. Today I also heard him swallow sort of loud. He just got over a URI and was taking doxycycline but that ended yesterday. I know lip licking can be associated with nausea, but his appetite is just fine and no vomiting. And idea what this could be? He's been through so much the past few week I hate to take him on another stressful vet visit if it isn't necessary.
