Cherry Eye in Dogs: Causes, Surgery & Recovery

Quick Answer
  • Cherry eye is a prolapse of the tear gland in the third eyelid. It usually looks like a smooth pink or red lump at the inner corner of the eye.
  • It is most common in young dogs, especially under 2 years old, and is seen more often in breeds like Bulldogs, Beagles, Cocker Spaniels, Boston Terriers, Pugs, and Shih Tzus.
  • It is often not a true emergency, but eye problems can worsen fast. Your dog should be examined by your vet within 24-72 hours, and sooner if there is squinting, discharge, rubbing, or a cloudy eye.
  • The third eyelid gland helps produce up to about half of the watery tear film, so vets usually recommend surgical replacement rather than removal.
  • Typical U.S. cost ranges in 2025-2026 are about $300-$1,200 per eye with a general practice vet and about $1,200-$2,500 with a veterinary ophthalmologist or for recurrent or complex cases.
Estimated cost: $300–$2,500

What Is Cherry Eye?

Cherry eye is the common name for prolapse of the gland of the third eyelid. Dogs have a third eyelid, also called the nictitating membrane, in the inner corner of each eye. That tissue contains an important tear gland that normally stays tucked out of sight. When the connective tissue holding it in place stretches or fails, the gland flips outward and becomes visible as a pink to red, rounded mass.

The lump can appear suddenly. In some dogs it comes and goes at first, then stays out. Even when it does not seem painful, the exposed gland can dry out, swell, and become more inflamed over time. That irritation can lead to redness, discharge, rubbing, and secondary corneal problems.

This gland matters. It produces a large share of the eye's watery tears, often cited as up to 50%. Because of that, modern treatment focuses on preserving and repositioning the gland, not removing it. Removal may lower tear production later and increase the risk of dry eye (keratoconjunctivitis sicca), which can become a lifelong management issue.

For many pet parents, the appearance is alarming. The good news is that cherry eye is usually very treatable, and many dogs do well after repair. The best plan depends on your dog's age, breed, how inflamed the gland is, and whether one or both eyes are affected.

Symptoms of Cherry Eye

  • Smooth pink or red round mass at the inner corner of the eye
  • Mass that appears off and on at first, then stays visible
  • Watery, stringy, or mucus-like eye discharge
  • Redness of the eye or surrounding tissues
  • Pawing at the eye or rubbing the face on furniture or carpet
  • Squinting, blinking more than usual, or holding the eye partly closed
  • Swollen gland that looks larger, drier, or more irritated over time
  • Cloudiness of the eye surface, which can suggest a corneal ulcer and needs prompt care

Cherry eye is often easy to spot, but not every red lump in the inner eye corner is cherry eye. Scrolled cartilage, severe inflammation, trauma, and less commonly tumors can look similar. Mild cases may only show a small pink bump with little discomfort. More concerning signs include squinting, thick discharge, obvious pain, a cloudy cornea, or repeated rubbing. Those signs raise concern for a corneal scratch or ulcer, and your dog should see your vet as soon as possible. Even uncomplicated cherry eye is best checked within a few days because a chronically exposed gland can become more swollen and harder to repair.

What Causes Cherry Eye?

Cherry eye happens when the tissues anchoring the third eyelid gland are not strong enough to keep it in its normal position. The exact cause is not fully understood, but the condition is widely considered to have a hereditary or breed-related component. In other words, many dogs are born with a tendency toward weaker connective support in that area.

It is seen most often in young dogs, especially those under 2 years old. Some reports note that many cases appear before 1 year of age. Breeds commonly listed as higher risk include English Bulldogs, French Bulldogs, American Cocker Spaniels, English Cocker Spaniels, Beagles, Boston Terriers, Pugs, Shih Tzus, Lhasa Apsos, and Bloodhounds. Giant breeds can also have third eyelid problems, and Great Danes may develop a similar-looking issue called scrolled cartilage.

Cherry eye is not usually caused by something your dog did wrong, and it is not typically from poor care. It is also not usually caused by infection. Inflammation can make the gland look worse, but the underlying problem is structural. If one eye develops cherry eye, the other eye may also be affected later, so pet parents should keep watching closely.

Because breed and anatomy matter, brachycephalic dogs may be overrepresented. That does not mean every flat-faced dog will develop cherry eye, but it does help explain why some families see it early in puppyhood.

How Is Cherry Eye Diagnosed?

Cherry eye is usually diagnosed during a physical and eye exam. Your vet will look at the position of the third eyelid gland and check whether the tissue is inflamed, ulcerated, or complicated by another eye problem. In many dogs, the appearance is classic enough that diagnosis is straightforward.

That said, a full eye exam still matters. Your vet may use a Schirmer tear test to measure tear production and a fluorescein stain to look for a corneal ulcer. These tests are especially helpful if the eye is painful, the gland has been prolapsed for a while, or your dog has had previous eye surgery.

Your vet may also consider look-alike conditions. Scrolled cartilage of the third eyelid can mimic cherry eye, and in some dogs the difference is only fully clear during sedation or surgery. Less commonly, masses, trauma, or severe conjunctival swelling can resemble a prolapsed gland.

A routine exam visit may run about $70-$150, with tear testing and stain testing often adding $25-$60 each. If surgery is planned, pre-anesthetic lab work commonly adds $100-$250. Referral to a veterinary ophthalmologist may be recommended for recurrent cases, bilateral disease, unusual anatomy, or if your dog already has other eye conditions.

Treatment Options for Cherry Eye

Spectrum of Care means you have options. Here are treatment tiers at different price points.

Conservative: Short-Term Medical Support

$50–$250
Best for: Dogs waiting for surgery, dogs with a newly prolapsed gland that is still small and intermittently visible, or families who need a brief bridge plan while arranging referral or budgeting.
  • Eye exam with your vet
  • Lubricating eye drops or ointment to protect exposed tissue
  • Short course of anti-inflammatory eye medication if your vet feels it is appropriate
  • E-collar if your dog is rubbing the eye
  • Monitoring for discharge, squinting, corneal ulceration, or worsening swelling
Expected outcome: This may reduce irritation and swelling for a short time, but it usually does not keep the gland in place long term. Many dogs eventually need surgery.
Consider: Lower upfront cost and less immediate intervention, but it is not usually definitive care. Delaying too long can allow the gland to become more inflamed and may make repair harder.
Most Common

Standard: Surgical Gland Repositioning

$300–$1,200
Best for: Most dogs with uncomplicated cherry eye in one or both eyes when the goal is to preserve tear production and correct the prolapse.
  • Pre-op exam and surgical planning
  • General anesthesia with monitoring
  • Gland replacement using a pocket technique, anchoring technique, or surgeon-preferred method
  • Post-op medications such as lubricant, antibiotic, and/or anti-inflammatory eye medication
  • Recovery cone and home-care instructions
  • Recheck visit in about 10-14 days
Expected outcome: Many dogs do very well after surgery. Reported first-surgery success rates vary by technique and case, but are often in the roughly 75-90% range.
Consider: Requires anesthesia and home care. Some dogs have recurrence and need a second procedure. Recovery usually takes about 10-14 days, and rubbing the eye can disrupt the repair.

Advanced: Ophthalmologist Repair or Revision Surgery

$1,200–$2,500
Best for: Recurrent cherry eye, severe swelling, unusual anatomy, brachycephalic dogs with multiple eye issues, or pet parents who want specialist-level care from the start.
  • Veterinary ophthalmology consultation
  • Advanced or combined repair techniques for recurrent or difficult cases
  • Management of concurrent problems such as corneal ulcer, dry eye, or scrolled cartilage
  • Bilateral repair during one anesthetic event when appropriate
  • Specialist follow-up and revision planning if needed
Expected outcome: Specialist care can improve planning and may improve success in complex cases. Many recurrent cases can still be managed successfully with revision surgery.
Consider: Higher cost range and possible travel time. Not every dog needs a specialist, but referral can be very helpful when the first repair fails or other eye disease is present.

Questions to Ask Your Vet About Cherry Eye

Bring these questions to your vet appointment to get the most out of your visit.

  1. You can ask your vet: Do you think this is definitely cherry eye, or could it be scrolled cartilage or another eye problem? A similar-looking condition can change the surgical plan and the expected recovery.
  2. You can ask your vet: Is my dog's eye irritated enough that we should treat it right away, or can we safely schedule surgery in the near future? This helps you understand urgency and whether short-term medical support is reasonable.
  3. You can ask your vet: Which repair technique do you recommend for my dog, and how often do you perform this surgery? Experience and technique can affect recurrence risk and help set realistic expectations.
  4. You can ask your vet: Will you preserve the gland rather than remove it? Preserving the gland helps protect long-term tear production and lowers dry eye risk.
  5. You can ask your vet: What is the chance the other eye could develop cherry eye later? That helps with monitoring and financial planning, especially in predisposed breeds.
  6. You can ask your vet: What medications, cone use, and activity limits will my dog need after surgery? Clear aftercare instructions reduce rubbing, swelling, and accidental damage to the repair.
  7. You can ask your vet: If the gland prolapses again, what would the next step be? Knowing the backup plan ahead of time can make recurrence less stressful.

Can Cherry Eye Be Prevented?

Cherry eye usually cannot be fully prevented because it is tied to anatomy and inherited tissue weakness rather than day-to-day care. There is no proven supplement, exercise, or home routine that reliably prevents the third eyelid gland from prolapsing.

What you can do is catch it early. If your dog is in a higher-risk breed group, get familiar with what the inner eye corner normally looks like. A small pink bump that appears and disappears can be the first sign. Early evaluation may help reduce prolonged irritation and can make planning easier.

Avoid repeated attempts to push the gland back in at home unless your vet has shown you exactly what to do and advised it as a short-term measure. Rough handling can irritate the tissue, and repeated manipulation does not fix the underlying problem.

One prevention-related choice does matter after diagnosis: preserving the gland whenever possible. Surgical replacement supports long-term tear production better than removal. If your dog has already had cherry eye in one eye, keep watching the other eye and contact your vet promptly if you notice a similar lump.
