Poor Bailey. The diarrhea could be present for many reasons and it could be related to a vaccine reaction. Parasites, bacteria overgrowth, a change in diet or something more sinister like parvo are also possible. I recommend to play it safe and have Bailey examined today by the veterinarian. Taking a sample of feces for testing. Best of luck.
