Cherry Eye in Pugs

The third-eyelid gland is normally anchored in place by a thin band of connective tissue. In some dogs, and brachycephalic breeds are frequently among them, that connective tissue is weaker than average, allowing the gland to flip outward under normal blinking pressure or minor irritation. Once prolapsed, the exposed gland tends to swell further from irritation and exposure to air, which is why the bulge often looks worse the longer it's left untreated, even though the underlying cause is a mechanical, structural weakness rather than an infection or injury.

Older treatment approaches sometimes simply removed the prolapsed gland outright, but that gland produces a meaningful portion of a dog's tear film, and its removal is now understood to raise the risk of chronic dry eye later in life. Current veterinary practice favors a repositioning surgery, sometimes called a pocket technique, that tucks the gland back into its normal position and stitches it in place rather than removing it. This preserves tear production while resolving the visible prolapse, though there's a modest chance of recurrence requiring a second procedure.

If you think your Pug has cherry eye, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers brachycephalic airway syndrome (boas), pug dog encephalitis, corneal ulcers.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for cherry eye it is often what separates a clear pattern from a guess.
