Cherry eye in dogs is treated with surgery to reposition the prolapsed gland back into its normal location. This is the only reliable fix. While you might see the gland pop out as a red, swollen lump in the corner of your dog’s eye, the goal of treatment is always to preserve the gland rather than remove it, because it produces roughly 30 to 50 percent of your dog’s tear film.
What Causes Cherry Eye
Dogs have a third eyelid, a thin membrane tucked in the inner corner of each eye. Attached to that membrane is a small tear-producing gland held in place by connective tissue. Cherry eye happens when that connective tissue is too loose or weak, allowing the gland to flip out of position and bulge forward as a pink or red mass. This is a structural defect, likely inherited, and it overwhelmingly shows up in young dogs under two years old.
Some breeds carry dramatically higher risk. Neapolitan Mastiffs are about 34 times more likely to develop cherry eye than mixed-breed dogs. English Bulldogs follow at 24 times the risk, then Lhasa Apsos (12 times), American Cocker Spaniels (nearly 12 times), Puggles (roughly 10 times), Great Danes (6 times), and Saint Bernards (5 times). Flat-faced breeds as a group are about seven times more likely to develop the condition. If your dog falls into one of these categories and you notice a red bump in the corner of their eye, cherry eye is the most probable explanation.
Why Surgery Is the Standard Treatment
You may have read about gently massaging the gland back into place at home. While it’s sometimes possible to temporarily push the gland back behind the third eyelid, it almost always pops out again because the underlying connective tissue hasn’t been repaired. Manual reduction is not a lasting solution. The gland will continue to prolapse, and the longer it sits exposed, the more irritated and swollen it becomes.
Surgery is the only treatment that addresses the root problem. The goal is to tuck the gland back where it belongs and secure it there permanently, preserving both its tear production and the normal movement of the third eyelid.
Surgical Techniques
The most widely used procedure is called the Morgan pocket technique. The surgeon creates a small pocket in the tissue lining the inside of the eyelid (the conjunctiva), nestles the gland into that pocket, and stitches it closed. This buries the gland in its natural position beneath the eyeball, where it can keep producing tears normally. The approach maintains full mobility of the third eyelid.
A second option is the tacking technique, where the gland is anchored directly to nearby bone or muscle with a suture. This is sometimes used when the pocket technique isn’t ideal for a particular dog’s anatomy, or as a second attempt if the first repair fails.
In rare, severe cases where the gland is badly damaged or diseased, a vet may recommend removing it entirely. This is considered a last resort because losing the gland significantly reduces tear production, putting the dog at high risk for chronic dry eye that requires lifelong treatment with artificial tears.
Success Rates and Recurrence
Cherry eye surgery carries an 85 to 90 percent success rate, according to Colorado State University’s veterinary ophthalmology service. That means roughly one in ten dogs will experience a recurrence where the gland prolapses again after repair. Recurrence is more common in breeds with extreme facial anatomy and in dogs that had very swollen glands before surgery.
When a repair fails, a second surgery is typically performed. The vet may repeat the same technique or switch to a different approach. In some cases, the T-shaped cartilage that supports the third eyelid has a structural bend contributing to the problem, and correcting that cartilage issue becomes part of the revision surgery. Most dogs do well after a second procedure.
Possible Complications
Beyond recurrence, the most notable complication is cyst formation at the surgical site. Fluid-filled cysts can develop in the tissue around the repositioned gland weeks or months after surgery. These are usually straightforward to diagnose and resolve with a minor procedure to remove the cyst wall.
Temporary swelling and redness after surgery are normal and expected. In uncommon cases, sutures can irritate the surface of the eye and cause a corneal ulcer, which is why post-operative checkups matter. Your vet will typically prescribe eye drops to manage inflammation and prevent infection during healing.
What Recovery Looks Like
Your dog will need to wear a cone (Elizabethan collar) after surgery to prevent pawing or rubbing at the eye. This is critical. A single determined scratch can undo the repair before the tissue has healed. Most vets recommend the cone stay on for at least two weeks, though the exact timeline depends on how quickly your dog heals.
Expect to apply medicated eye drops several times a day during recovery, typically a combination of anti-inflammatory and antibiotic drops. Activity should be limited for the first week or two. Swelling around the eye usually improves noticeably within the first few days, though mild puffiness can linger for a couple of weeks. A follow-up visit about two weeks after surgery lets the vet confirm the gland is staying in place and the stitches are dissolving properly.
Most dogs return to their normal selves within two to three weeks. The repaired eye looks and functions normally once healing is complete.
How Much Cherry Eye Surgery Costs
The price ranges widely depending on where you live, whether one or both eyes need repair, and whether you see a general vet or a veterinary ophthalmologist. Reported costs range from $300 to $2,500. Insurance claims data from MetLife suggests many procedures fall in the $300 to $800 range, while specialty eye clinics tend to charge more. As a reference point, one Colorado specialty center quotes $1,200 to $1,600 for correcting both eyes, while another quotes $1,500 to $1,900.
If your dog’s breed is predisposed and they develop cherry eye in one eye, there’s a reasonable chance the other eye will follow. Some owners opt to address both eyes in a single surgical session when the second eye looks likely to prolapse, which can reduce overall costs compared to two separate procedures.
What to Do When You First Notice It
Cherry eye is not a medical emergency, but it shouldn’t be ignored. The longer the gland stays prolapsed and exposed to air, the more inflamed it becomes, which can make surgical repair harder and increase the chance of complications. Schedule a veterinary appointment within a few days of noticing the red lump. In the meantime, you can use a warm, damp cloth to gently clean any discharge around the eye. Keep your dog from rubbing at it if possible.
If your vet confirms cherry eye, ask whether they’re comfortable performing the repair or whether a referral to a veterinary ophthalmologist would be more appropriate. For straightforward cases in common breeds, many general practice vets handle the surgery routinely. For complex or bilateral cases, a specialist may offer a better outcome.
