Red 3rd eyelid covering part of inner eye and squinting
Hi, So my chocolate lab had reddish slightly swollen but mainly just red in the inner corner of her eye. First it was one then it was both and then one night it disappeared completely. The next day it slowly came back.
Would this be some sort of infection or allergies? In the Midwest we have higher than normal tree pollen right now but my dog has never had allergies before. Or any other health condition. She's about to turn 13 in july.
