My 11-year-old dog's third eyelid is covering his eye, what's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | unneutered | 11 years and 4 months old | 78 lbs

My 11-year old golden retriever-irish setter mix has experienced some kind of eye problem for the past two weeks. It seems that his third eyelid has covered half of his right eye. His left eye is completely normal. I don't remember him suffering some sort of trauma to his head.

Hi, and thanks for your question. That is likely to be due to a mild to moderate conjunctivitis, probably secondary to a trauma or infection. A check up would be needed as appropriate treatment would include antibiotics and anti-inflammatory eye drops. Corneal injuries must be ruled out as well. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be used to improve our service.

    Hi there and thank you for using pet coach to address your concern. If she was recently in for hemorrhagic diarrhea and is still not back to her regular self, I would recommend having a veterinarian examine her so that the most appropriate diagnostic and treatment recommendations can be made. The third eyelid being prominent could be indicative of some other systemic process going on or it may be an allergic reaction that needs medical attention. If you are able to get her seen as an emergency, I would recommend doing so to be on the safe side. Allergic reactions can become severe if left untreated. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

    Por Marshall! He could have an eye infection, may have allergies, or could have injured his eye. The eye is such an important and delicate structure that any problem with it should be considered an emergency. That's because leaving it untreated can lead to vision loss. He needs to have his eye seen and examined now so it can be treated. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

    This appears to be a "cherry eye" but it is not a common problem in this age dog. It usually first manifests in puppies. At his age I would be a bit worried that this is a cancerous tumor. Definitely get him to the vet for an exam. Chances are that surgery is needed to correct this problem.
