Should I worry if my dog's eye is red, milky blue, and third eyelid showing?

Updated On September 23rd, 2025

Pet's info: Dog | Boxer | Male | neutered | 50 lbs

My dogs eye was red yesterday and this morning I noticed it’s milky blue and his third eyelid is showing. It’s also watering a little bit. We thought that maybe he scratched it or poked it on something? Our vet told us that when they turn 7, their eyes start to get milky and he is the age, but it’s just one eye. Thought it was a little weird. Is it something worth taking him to the vet?

Hello, It is difficult to tell from pictures exactly what is going on but Calvin’s right eye does not appear normal. He may have an ulcer and/or elevated pressure in the eye. Also, I cannot determine if he has pigment on the cornea or an abnormality of his iris. Either way you need to follow up with a veterinarian or veterinarian ophthalmologist as soon as possible.
