Dog Cherry Eye: Symptoms, Treatment, and Surgery Outlook
Cherry eye is a red, lumpy swelling at the inner corner of your dog's eye where the third-eyelid gland has popped out of place. It is not painful at first, but the gland produces 30 to 50 percent of your dog's tears — surgical replacement (not removal) is the treatment, and waiting risks long-term dry eye.

What Cherry Eye Looks Like
Cherry eye is the lay term for prolapse of the third-eyelid gland — a small almond-shaped gland tucked behind the inner edge of the third eyelid. When the tissue that anchors it loosens or breaks, the gland pops up over the eyelid edge, looking like a smooth red cherry sitting in the inner corner of the eye. It can happen suddenly. Brachycephalic breeds (Bulldogs, French Bulldogs, Boston Terriers, Pugs, Shih Tzus, Cocker Spaniels, and Beagles) account for the great majority of cases. Most affected dogs are under 2 years old. About 40 to 50 percent of dogs with cherry eye in one eye will develop it in the other eye within months.
Why It Matters
The prolapsed gland is not painful initially and looks scary but rarely is an emergency. However, the gland produces 30 to 50 percent of the dog's tear film, and a gland left out of place for weeks to months loses function. Dogs that have the gland surgically removed (an older approach now considered inappropriate) develop chronic dry eye in roughly 40 to 50 percent of cases. The modern approach is to surgically tack the gland back into place, preserving tear production (Plummer et al., 2008, Veterinary Ophthalmology), as described in Slatter's Textbook of Small Animal Surgery. Routine puppy wellness should screen for early breed-specific eye conditions (AAHA Canine Life Stage Guidelines, 2019).
Treatment — Surgery is the Standard
Two main surgical techniques are used: the pocket (Morgan) technique and the suture (anchoring) technique. Both have success rates of 80 to 95 percent in experienced hands. Surgery is usually scheduled within 2 to 4 weeks of diagnosis. The vet may prescribe lubricating and anti-inflammatory drops in the interim. Manual replacement at home does not work — even if the gland goes back temporarily, it almost always pops out again. Recurrence after proper surgery is about 5 to 20 percent and can be re-corrected.
Home Care Before and After Surgery
Use prescribed lubricating drops (artificial tears, hyaluronate) 3 to 4 times daily to keep the gland from drying out. Keep the dog from rubbing the eye on furniture or grass. After surgery, an e-collar is worn for 10 to 14 days, with topical antibiotic and anti-inflammatory drops as prescribed. Recheck visits at 1 week and 2 to 4 weeks. Schedule a tear-production test (Schirmer) at the 6-month mark to confirm the gland is functioning.
When to See a Vet
Not every symptom is a midnight emergency, but some warrant same-day attention and a few are true ERs. Use the lists below to sort which bucket you're in.
Call your vet today if:
- Red, round swelling in the inner corner of your dog's eye
- Mild squinting or rubbing the affected eye
- Watery or mucousy discharge from one eye
- Eye looks irritated or dog blinks excessively
- Cherry eye on the other side now appearing
Go to the ER immediately if:
- Cherry eye plus severe swelling, bleeding, or eye trauma
- Sudden onset with intense pain — vocalizing, pawing constantly
- Cloudy cornea or visible ulcer alongside cherry eye
- Eyeball appears displaced or larger than the other
- Yellow or green discharge with fever, lethargy, or loss of appetite

Frequently Asked Questions
Can cherry eye in dogs go away on its own?
It very rarely resolves spontaneously. Some glands briefly pop back in but almost always re-prolapse, and the longer the gland stays out, the more it can swell and lose function. Surgical replacement within a few weeks gives the best chance of preserving tear production.
How much does dog cherry eye surgery cost?
Initial vet exam runs $50–150 and topical eye medications add $40–100. Cherry eye surgery by a general practitioner costs $300–800 per eye, while a board-certified veterinary ophthalmologist typically charges $1,000–2,000 per eye. If both eyes are affected and done together, total surgical cost commonly runs $1,500–3,500. Tear-replacement therapy for life (if the gland is removed or dries out) is $30–80 per month.
Will my dog get cherry eye in the other eye too?
About 40 to 50 percent of dogs with one-sided cherry eye develop it on the other side within months. Some surgeons recommend preventive tacking of the unaffected side at the same surgery in high-risk breeds, especially Bulldogs and French Bulldogs.
Is cherry eye painful?
Initially it is more cosmetically alarming than painful. Over days to weeks, the exposed gland can dry out and become irritated, leading to rubbing, blinking, and possible secondary infection. Most dogs are surprisingly unbothered the first day or two, which can lead owners to delay — surgery within a few weeks is still the right plan.
