For the past few days, Daisy has been waking up with her left eye all gooped over. My mom cleans it off in the morning ('cause she lets the dogs out to potty) and there is no excessive discharge during the day, and Daisy doesn't rub her eye. Daisy's eyes have always been slightly runny though. Could her left eye be having an allergy problem? I have been feeding Wellness and its helped with Daisy's skin allergies greatly.
