Poor Bubba! From the picture, it looks like the ring may be the edge of his 3rd eyelid. If he is squinting and the third eye lid is further up than normal, he likely either has an infection, foreign object in his eye, or a corneal ulcer. I would have your vet take a look at it so they can determine the cause and get him started on something to help him feel better. You can also start him on some Benadryl twice a day to help with any allergy component. See link below. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl/#!
