It is often not painful at first, but the exposed gland can become irritated, inflamed or injured, so call a vet and arrange an exam promptly. Don't push or massage the lump unless a veterinarian tells you exactly how. Treatment usually aims to replace and keep the gland, because removing it raises the risk of chronic dry eye, according to the [American College of Veterinary Ophthalmologists](https://www.acvo.org/common-conditions-1/2018/2/2/cherry-eye). ### Key takeaways - A smooth pink or red lump in the inner corner of the eye is usually a prolapsed third-eyelid gland, but only an exam can confirm it. - Call a vet for triage the same day you see it. Squinting, pawing, thick discharge, cloudiness, a scratch or an eye your dog can't open means same-day or emergency care. - Don't push, press or massage the lump, and don't use any eye drops unless a veterinarian prescribed them for this eye. - The gland makes a large share of your dog's watery tears, so surgery usually replaces it. Removal raises the risk of lifelong dry eye. - Cherry eye is not contagious, it can come back after surgery, and the other eye may be affected later. - Surgery prices vary by region and clinic, so ask for a written local estimate, and ask your insurer about pre-existing and hereditary exclusions. ## Does my dog need a vet today, and which signs decide it? I know a bright red lump on your dog's face is alarming, and you want to know how fast to move. A visible third-eyelid swelling or red mass deserves prompt veterinary attention. It can look like other third-eyelid problems, and the longer the gland stays exposed, the more it can be irritated and the less well it may work. Call your regular vet or an [emergency vet](https://dogserv.com/directory/vets/) and describe what you see. Follow the clinic's triage advice on timing. Go in the same day, or straight to an emergency clinic, if you see any of these, as listed by the [ACVO](https://www.acvo.org/tips-treatments-tricks/how-many-eyelids-does-my-pet-have) and the [ASPCA](https://www.aspca.org/pet-care/dog-care/dog-grooming-tips): - Squinting, or an eye held tightly shut - Pawing or rubbing at the eye that doesn't stop - Thick yellow, green or bloody discharge - Cloudiness, or a visible scratch on the surface of the eye - Marked redness or swelling - A sudden change in vision - Pupils that are different sizes - A bulging eyeball or any major injury to the face - Severe pain, unusual tiredness, or an eye your dog can't open If the lump is the only thing you see and your dog is acting comfortable, a prompt regular appointment may be right. The clinic makes that call, so phone rather than wait and watch. ## What does cherry eye look like, does it hurt, and can another dog catch it? Dogs have a third eyelid, a membrane at the inner corner of the eye. It protects and moistens the eye, and it holds a gland that makes part of the tear film. In cherry eye, that gland slips out of position and shows as a smooth pink or red mass, according to [Cornell University College of Veterinary Medicine](https://www.vet.cornell.edu/departments-centers-and-institutes/riney-canine-health-center/canine-health-topics/cherry-eye-dogs). It is usually seen in young dogs, often before age two. Cornell lists American and English Cocker Spaniels, Beagles, English and French Bulldogs, Pugs and Boston Terriers as predisposed, and [VCA](https://vcahospitals.com/roberts/know-your-pet/cherry-eye-in-dogs) names several more, including Shih Tzus, Lhasa Apsos and Great Danes. The exact cause isn't fully established. Vets point to weak or abnormal connective tissue holding the gland in place, with a likely genetic part. Any dog can be affected, and nothing you did at home caused it. Cherry eye itself is often not painful at first. The trouble is the exposed tissue, which can become irritated and inflamed, bleed if it's rubbed, and become infected. A dog who squints, paws or rubs at the eye is telling you it hurts. Cherry eye is not contagious. It is a problem of gland support and anatomy, so it doesn't pass between dogs. A red eye from another cause can be infectious, though, which is one more reason to have any red eye examined. Our guide to [dog eye infections](https://dogserv.com/dog-eye-infections/) covers those causes. Appearance alone doesn't confirm the cause. Vets also look for scrolled cartilage of the third eyelid, a painful eye problem such as a corneal ulcer pushing the third eyelid up, conjunctivitis, dry eye, trauma or a foreign body, nerve problems such as Horner syndrome, rare tumors, and eyelid problems such as entropion. Cornell notes that telling scrolled cartilage from cherry eye can take an exam under anesthesia. ![Young black and white Boston terrier lying on an oatmeal sofa cushion beside a window, face relaxed and eyes clear](https://dogserv.com/blog/cherry-eye-in-dogs/what-it-looks-like.jpg) ## What should I not do at home while I wait for the appointment? This is where owners often reach for a fix, and I'd hold off on all of them. Don't push the lump back in, and don't massage it. A vet may sometimes show you a specific repositioning or massage approach for an individual dog, but that is a vet's instruction for your dog. Pressing on the eye or the gland can cause bleeding or damage the surface of the eye. Don't use leftover drops from a previous problem, and don't use human eye drops. Eye lubricants and anti-inflammatory eye medicines belong in the eye only when a veterinarian has prescribed or directed them for this problem. If someone tells you a home remedy will shrink it, the veterinary answer is to get the eye examined. What you can do today is simple: - Photograph the eye without touching it, so the vet can see how it looks now. - Call a vet for triage and describe the lump, the discharge and your dog's behavior. - Stop your dog from rubbing or pawing at it. A clean soft cone or a gentle hold with you watching can help until you're seen; ask the clinic what they suggest. - Keep your dog away from dust, hair clippers, grooming sprays and anything that could get in the eye. The swelling sometimes shrinks for a while. [Merck Veterinary Manual](https://www.merckvetmanual.com/es-us/propietarios-de-perros/trastornos-oculares-de-los-perros/trastornos-de-la-cavidad-nasal-y-los-conductos-lagrimales-en-los-perros) says the gland often stays displaced even then, so a smaller lump doesn't mean the problem is fixed. Keep the appointment. ## What happens if cherry eye is left untreated? A gland that stays out of place keeps getting exposed. That can mean ongoing irritation and inflammation, less tear production over time, and a higher chance of dry eye, which is known as keratoconjunctivitis sicca. Dry eye can lead to corneal ulcers and secondary infection, as Cornell and the ACVO explain, and dry eye in dogs often means eye medication for life. The gland matters because it makes a big share of the watery part of your dog's tears. Cornell says up to 50%. The ACVO gives a range of 33% to 66%, and a VCA SouthPaws ophthalmology handout gives 40% to 50%. However you count it, losing a gland that supplies roughly a third to a half of the tears is a real loss for the eye. So, no, cherry eye isn't only a cosmetic issue, and waiting for it to go away isn't a plan. The eye is easier to protect when a vet is involved early. ![Senior fawn pug with a greying muzzle lying on a round dog bed next to a plain steel water bowl in a quiet bedroom](https://dogserv.com/blog/cherry-eye-in-dogs/left-untreated.jpg) ## What will the veterinarian check? Expect a hands-on look at both eyes, a check of the third eyelid and the lump, and questions about when it appeared, whether your dog has been squinting or rubbing, and whether the other eye has ever looked like this. The vet may run a Schirmer tear test. It measures how many tears the eye is making, and it tells your vet how well the eye is protected right now. They may add other eye checks if something looks like more than a prolapsed gland, such as a scratch or inflammation inside the eye. If scrolled cartilage is a possibility, an exam under anesthesia may be needed. Good questions to bring: - Is this a prolapsed gland, or could it be something else? - Will you test tear production? - Is surgery to replace the gland the plan, and will it be a general vet or a veterinary ophthalmologist? - Is the other eye normal today? If you need to find a clinic, our [veterinarian directory](https://dogserv.com/directory/vets/) lists vets across the country. ## What does cherry eye surgery involve, and why is the gland usually kept? Surgery generally aims to replace the gland and preserve it. The [ACVO](https://www.acvo.org/common-conditions-1/2018/2/2/cherry-eye) says surgical replacement is needed, and most veterinary ophthalmology sources agree. The main approaches are: - **Pocket technique, also called the Morgan technique.** The surgeon makes a pocket in nearby tissue, tucks the gland inside and closes the pocket with stitches. - **Anchoring technique.** The gland is stitched to nearby supporting tissue. - **Combined or modified techniques.** The surgeon picks an approach based on the gland, how long it has been out, your dog's anatomy and the surgeon's experience. Cornell says the best technique depends on the dog and the surgeon's preference. A 2019 [Veterinary Evidence review](https://veterinaryevidence.org/index.php/ve/article/download/182/version/160/277) found not enough evidence to say that pocket or anchoring surgery is better at preventing recurrence. A 2025 [PubMed study](https://pubmed.ncbi.nlm.nih.gov/40415639/) of 126 eyes reported that 125 were repositioned after one surgery with a variant pocket technique, about 99.2%, in under 10 minutes per surgery. That study also reported complications, and it can't promise the same result for your dog. Removal used to be common, and it's now generally avoided. The ACVO says removing the gland predisposes dogs to dry eye that may need medication several times a day for life. An older [AVMA journal article](https://avmajournals.avma.org/downloadpdf/journals/javma/205/10/javma.1994.205.10.1412.pdf) reported dry eye in 14% of replacement cases and 48% of removal cases. Removal is kept for rare severe or tumor-related cases.

Recovery usually means an e-collar so your dog can't rub the eye, short-term eye medicine prescribed by your vet, and calm activity. VCA SouthPaws describes swelling and inflammation settling over one to two weeks. An [ASPCA case](https://www.aspca.org/news/ohio-urgent-dog-foster-needed-columbus) used a two-week quiet recovery with an e-collar and prescribed eye drops. Your vet's instructions for your dog come first, including how long to limit running, rough play and swimming, and when the recheck is. Give every dose exactly as the clinic says, and call them if the eye looks worse, your dog squints more, or the stitches or the lump look different. Recurrence is possible. VCA gives a general estimate of about 5% to 20%, and real results vary with the technique, the dog and the surgeon. One good surgery doesn't guarantee it never returns. The other eye can be affected too. Cornell says one or both eyes may be affected, and VCA says many dogs with one affected eye later develop prolapse in the opposite eye. Ask your vet to check the other eye at each visit. There is no home method to prevent the prolapse itself. What you can do is keep your dog from rubbing the eyes, protect them from irritants during grooming, and get any eye change looked at early. ## How much does cherry eye surgery cost, and will pet insurance pay? Cost depends on your region, the clinic, anesthesia, testing, whether one or both eyes need surgery, and whether a specialist is involved. For a sense of scale from outside the US, the Royal Veterinary College in the UK lists £1,950 to £2,300 for one eye, including a specialist consultation, general anesthesia, surgery, one night in hospital, pain relief and hospital medicines. That is a UK specialist price, not a US one, so don't plan around it. For a US number, ask for a written local estimate. Ask what it covers: the exam, tear testing, anesthesia, surgery, take-home medicines, the e-collar, follow-up visits and any referral. Getting two estimates, one from your regular vet and one from a veterinary ophthalmologist, lets you compare. Insurance is policy-specific. Coverage turns on your enrollment date, waiting period, whether hereditary or congenital conditions are covered, bilateral-condition wording, the deductible, the reimbursement rate, and whether the condition was present or documented before coverage began. AKC Pet Insurance lists cherry eye as a [pre-existing condition](https://www.akcpetinsurance.com/plans/pre-existing-conditions) and describes limited pre-existing coverage after 365 days of continuous coverage, subject to its terms and state availability. Questions for your insurer: - Is cherry eye covered if it first appears after enrollment and the waiting period? - Are hereditary or congenital conditions covered? - Does a problem in one eye exclude the other eye? - Are the exam, anesthesia, surgery, medicines and specialist fees covered? - Is there a bilateral or related-condition clause, and what records do you need to send? Our [pet insurance guide](https://dogserv.com/pet-insurance-for-dogs/) explains how pre-existing conditions are treated in general. **Quiz: Quick check: cherry eye in dogs** 1.

Price depends on where you live, the clinic, whether a specialist does it and whether one or both eyes are done. Ask for a written local estimate that lists the exam, tear test, anesthesia, surgery, medicines and rechecks, and ask what happens if a second surgery is needed. ### Can I push my dog's cherry eye back in? Please don't. Pressing on the eye can cause bleeding or hurt the surface of the eye. Ask your vet whether any temporary step is right for your dog. ### Is cherry eye contagious? No. It comes from how the gland is held in place, and breed and genetics play a part. It doesn't spread between dogs, but a different red-eye problem might, so have any red eye examined. ### How painful is cherry eye in dogs? Often it isn't painful at first. If your dog squints, paws at the eye, holds it shut or has thick discharge, the eye is irritated or injured and needs a vet that day. ### Is it okay to leave cherry eye untreated? Waiting puts the eye at risk of ongoing irritation, lower tear production and dry eye. Even if the lump shrinks for a while, the gland often stays displaced, so book the exam. ### Is cherry eye surgery worth it? Replacing the gland keeps the tear supply the eye depends on, while removal raises the risk of lifelong dry eye and daily medicine. Many dogs do well, though recurrence is possible, so talk through the options with your vet. ## What should I do next? Take a photo without touching the eye, then call a vet for triage today. If your dog is squinting, pawing, has thick discharge or cloudiness, or can't open the eye, go to an [emergency vet](https://dogserv.com/directory/vets/) or a nearby clinic from our [veterinarian directory](https://dogserv.com/directory/vets/) right away. Bring your questions about replacing the gland, testing tears, the other eye, a written estimate and your insurance. If your dog's eye looks cloudy, our guide to [cataracts in dogs](https://dogserv.com/cataracts-in-dogs/) explains that separate problem, and if your dog is scratching at the face often, our [dog allergies guide](https://dogserv.com/dog-allergies/) covers common causes.
