For the past week or so, Lola has had increased eye discharge that's yellowish in color. I wipe it off but more comes back. And tear stains have formed now, she never had them before. Could this be an eye infection or just allergies? I bought some tear stain removal stuff from PetSmart....could that have made it worse? I was thinking of giving her a Benadryl when I got home and see what happens?
