Dog Cherry Eye: What the Red Swelling Means, Home Limits, and Surgery Conversations

Cherry eye in dogs is a prolapsed gland of the third eyelid that appears as a red or pink mass in the corner of the eye. It is not a surface “pimple.” The gland normally helps produce tears; when it slips out of position it becomes visible and irritated. Mild cases sometimes stay small; many dogs need surgical replacement rather than gland removal so long-term tear production is protected.
The third eyelid (nictitating membrane) sits in the inner corner and carries a tear gland. In cherry eye, that gland prolapses and looks like a cherry-sized swelling. Young dogs and certain breeds (including some bulldogs, beagles, cocker spaniels, and Shar-Peis) appear more often in clinic caseloads. One eye can be affected first; the other may follow later.
Weak connective tissue that should anchor the gland is the usual explanation. Inflammation and rubbing can make the swelling larger and more uncomfortable. It is not typically caused by something the dog “caught” from another pet.
If you also notice discharge, squinting, or cloudiness, treat that as higher urgency. Our guide on dog eye discharge covers colour and pain clues that often travel with eye problems.
Our Diagnostics Support pathway helps you organise photos, timelines, and questions for your veterinary team—including discussions about cherry eye surgery when recommended.
Some clinicians try medical management briefly for mild irritation. Many dogs still need a surgical tack-down or pocket technique to keep the gland in place. Removing the gland entirely is less preferred in modern practice because dry eye risk can rise later. Ask about recovery, Elizabethan collar use, and whether the second eye carries higher risk in your dog’s breed.
