Flat-faced dogs are more than eight times as likely as other dogs to develop a corneal ulcer, according to a large Royal Veterinary College study reported by Vet Times. For a Frenchie, that makes eye care a daily-life topic, not just a vet-visit topic. This guide walks through the most common French Bulldog eye problems, what each one looks like, which ones tend to show up at which age, and when a squint or a red eye should send you to the vet the same day. By the end, you’ll know what to watch for and what to do next.
Quick answer: The most common French Bulldog eye problems are conjunctivitis, cherry eye (a prolapsed gland of the third eyelid), and corneal ulcers. Dry eye, eyelid and eyelash problems, and juvenile cataracts also turn up. The breed’s flat face and prominent eyes leave the eye surface exposed. Redness, discharge, squinting, blinking a lot, or rubbing the eye are all reasons to call a vet promptly.

Why French Bulldogs Are Prone to Eye Problems
Most of the trouble starts with the Frenchie’s face. Researchers who studied corneal ulcers across dog breeds identified a short, flat skull shape, a nasal fold, and wide eyelid openings as risk factors, and all three are common in French Bulldogs (see the Royal Veterinary College paper on French Bulldog disorders). The UK Kennel Club’s Breed Watch list also flags excessively prominent eyes and an incomplete blink as concerns for the breed.
How common is it? In that same review of 2,228 French Bulldogs seen by UK vets in 2013, about 1 in 10 (10.5%) had an eye disorder recorded. The three most common were conjunctivitis (3.2%), prolapsed gland of the third eyelid, better known as cherry eye (2.6%), and ulcerative keratitis, meaning a corneal ulcer (2.1%).
Those numbers likely understate the real picture. The authors note that vet records tend to capture the more severely affected dogs, and that many breed-related problems are accepted as “normal for the breed” when they should not be.
Newer research adds an important detail. In a 2021 Royal Veterinary College study of 2,781 French Bulldogs and 21,850 other dogs seen by UK vets in 2016, corneal ulcers were recorded in 1.6% of French Bulldogs against 0.7% of other dogs, which works out to about 4.4 times the adjusted odds. Conjunctivitis was common (2.6% against 2.2%) but did not differ significantly from other dogs. Red, irritated eyes turn up in every breed, while ulcers are the problem the Frenchie’s face shape makes clearly more likely.
A December 2025 study from an animal eye practice in Berlin, published in Frontiers in Veterinary Science, found signs of a tear film deficiency, a type of evaporative dry eye, even in healthy French Bulldogs when compared with non-brachycephalic dogs. The authors also note that French Bulldogs are among the breeds most often seen in specialist eye clinics, making up 15.2% of all patients in one clinic in 2024.
The Most Common French Bulldog Eye Problems
Each condition below has its own deeper guide. This section is the short version, so you can recognize what you are looking at.
Conjunctivitis (Pink Eye)
Conjunctivitis is inflammation of the tissue that lines the eyelids and covers the white of the eye. It was the most common eye disorder recorded in the Royal Veterinary College review, and it showed up slightly more often in males (3.9%) than in females (2.4%). It has several possible causes, so the vet has to work out which one is behind it. Redness, discharge, and squinting are the usual signs.
If the main sign is a red eye, the guide to red eyes in French Bulldogs helps narrow down the possibilities.
Cherry Eye
Cherry eye is the common name for a prolapsed gland of the third eyelid. VCA Animal Hospitals explains that dogs have a third eyelid (the nictitating membrane) inside the lower eyelid, and that the gland attached to it can pop out of position. Owners usually see a swollen pink or red mass in the inner corner of the eye. That gland makes a significant share of the eye’s protective tear film, which is why the treatment choice matters.
One point matters a lot here. A veterinary specialist who works with Bulldogs warns that if the gland is removed instead of repositioned, the eye may not make enough tears to stay lubricated. Ask the vet about repositioning before agreeing to removal. The full story is in the cherry eye guide.
Corneal Ulcers
A corneal ulcer is a sore on the clear surface at the front of the eye. In one prospective clinical study cited by the Royal Veterinary College team, 15.4% of French Bulldogs had a corneal ulcer. Earlier UK data cited in the same paper found that French Bulldogs had about five times the odds of a corneal ulcer compared with crossbreed dogs.
Ulcers hurt. In a UK study of ulcer cases across breeds, 69.1% of records noted pain or included pain management. The Bulldog specialist quoted above also warns that untreated ulcers can cause severe corneal damage and permanent vision loss. That is why squinting should never be treated as a wait-and-see sign. More in the corneal ulcer guide.
Dry Eye (KCS)
Dry eye, known to vets as keratoconjunctivitis sicca (KCS), is inflammation of the eye typically caused by too little tear production. It appears on the Bulldog specialist’s list of common eye diseases, and it can lead to ulcers when left alone. A vet can test tear production, so this is a diagnosis for the clinic, not the living room. See the dry eye guide for details.
Entropion (Rolled-in Eyelid)
Entropion is a condition where the eyelid rolls inward, so the lid and its hair rub against the cornea. According to the same veterinary source, the irritation can cause pain and lead to corneal ulcers. Excessive blinking, squinting, and watery or mucus-like discharge are the clues. The eyelid problems guide covers what vets can do.
Ingrown or Misplaced Eyelashes (Distichiasis)
Distichiasis means an eyelash grows from an unusual spot, often growing toward the eye. The effect depends on how many lashes are involved and how stiff they are: one small, soft lash may cause no symptoms, while several stiff lashes can cause inflammation, discharge, and pain. Bulldog specialists also list ingrown lashes among the causes of corneal ulcers. Frequent blinking or pawing at the eye can be a sign of pain.
Cataracts, Including Juvenile Cataracts
A cataract is a hazy area in the lens of the eye. French Bulldogs are one of the breeds genetically predisposed to juvenile cataracts, which can appear in puppies. Cataracts in dogs are often inherited, but can also follow an injury or diabetes, and they are often seen in older dogs. A cloudy or bluish look in the eye is a reason to book a vet visit rather than wait.
How Vets Treat Each Eye Problem
Treatment depends on the cause, and only a vet can choose it. This is a quick guide to what to expect at the clinic, not a home treatment plan.
- Conjunctivitis: the vet treats the underlying cause. Allergies may call for eye drops or oral medication plus allergy control, while bacterial conjunctivitis is usually treated with topical antibiotics.
- Cherry eye: the treatment is surgery to put the gland back in place. VCA Animal Hospitals explains that the third eyelid gland produces up to 50% of the watery part of the tear film, and that replacing the gland is the first choice because removing it risks dry eye.
- Corneal ulcers: treatment depends on how deep the ulcer is. It can range from medicated drops and an E-collar to surgery, including removing damaged tissue or placing a graft.
- Dry eye (KCS): the vet replaces the tear film with lubrication and usually prescribes a tear-stimulating medication. A Bulldog specialist notes that most dogs with KCS need ongoing treatment.
- Entropion: surgery corrects the rolled-in eyelid. In some cases, temporary sutures or staples are enough.
- Ingrown or misplaced lashes (distichiasis): a dog with no pain may not need treatment. Otherwise, the vet may recommend lubricant or surgery that removes the lash and its follicle.
- Cataracts: surgery is the only treatment, and it replaces the cloudy lens with an artificial one, according to Dogster’s vet-reviewed guide.
Which Eye Problems Show Up at Which Age
Most French Bulldog eye guides list conditions one after another. The Royal Veterinary College data adds something more useful: some problems cluster in young dogs, and others become more common in adults. This is the age pattern from the 2013 review of French Bulldogs under UK veterinary care.
| Age group | What the data shows | What to do |
|---|---|---|
| Puppies and under 2 years | Cherry eye was recorded in 3.4% of dogs under 2, against 0.9% of dogs 2 and over. The median age of affected dogs was under 1 year. | Look at both eyes every few days, especially the inner corners. |
| 2 years and over | Corneal ulcers were recorded in 3.8% of dogs 2 years and older, against 1.3% of younger dogs. The median age at diagnosis was about 2.8 years. | Treat squinting, a closed eye, or sudden redness as urgent. |
| All ages | Conjunctivitis showed no clear age difference (3.4% under 2, 2.9% age 2 and over). | Stay alert at every life stage. |
Two cautions apply. First, the studied dogs were young (median age 1.3 years), so the pattern may shift as more older Frenchies are studied, as the authors say themselves. Second, inherited eye problems tend to start early: a veterinary eye center notes that genetic eye disorders usually cause problems in puppies in their first few months, which is a good reason to keep every scheduled puppy visit.
Signs Something Is Wrong With Your Frenchie’s Eyes
A Bulldog-focused veterinarian lists the usual presenting signs of eye trouble as redness, discharge, squinting, excessive blinking, pain, and rubbing at the eyes. In everyday terms, watch for:
- A red or bloodshot eye, or a red bulge in the inner corner
- Watery eyes or any new discharge
- Squinting, or an eye held partly or fully closed
- Pawing or rubbing the face on the carpet or sofa
- Blinking much more than usual
- A cloudy, bluish or hazy look
- A dog that flinches when the eye area is touched
One or two mild signs can still matter. Frenchies often hide discomfort, and the Royal Veterinary College authors caution that owners and vets both tend to accept breed-related problems as typical. The word “normal” can hide a real problem.
What the Color of Eye Discharge Can Mean
A small amount of clear, watery discharge that crusts a bit can be normal. These are rough clues, not diagnoses, based on All About Vision’s guide:
| What you see | What it can point to | What to do |
| Clear and watery, in small amounts | Often normal | Keep an eye on it |
| Yellow or green | Infection may be present | Book a vet visit |
| White or gray | Dry eye may be present | Book a vet visit |
| Bloody | May be serious | See a vet as soon as possible |
For tear stains and everyday cleaning, see the tear stains guide and the eye cleaning guide.
When to Call the Vet
The Bulldog specialist’s advice is simple: if you see signs of an eye problem, consult a veterinarian promptly, because early diagnosis and treatment may help prevent more serious complications. This table turns that advice into a quick guide.
| How urgent | What you see | What to do |
| Book a visit soon | Mild redness, a little new discharge or watering, occasional rubbing, no obvious pain | Call the vet’s office, describe the signs, and ask how soon the eye should be seen. |
| Same-day vet visit | Squinting, an eye held shut, heavy discharge, a red bulge in the corner of the eye, a cloudy look, or sudden redness | Do not wait overnight. Ulcers and other painful conditions can worsen quickly. |
| Emergency | An eye that looks suddenly swollen, bulging, or out of position, or any eye injury | Go to an emergency vet right away. [VERIFY BEFORE PUBLISHING: add a veterinary source for eye emergencies.] |
Do not rub, press on, or try to treat the eye yourself, and avoid using leftover drops from another pet or person. Only a vet can say what is safe to put in an eye.
How to Lower the Risk
No owner can change a Frenchie’s face shape, but a few habits help:
- Choose the breeder carefully. A veterinary eye center recommends buying from a responsible breeder who tests the parents’ genes, which lowers the chance of inherited eye problems.
- Keep the puppy visits. Early checks catch inherited problems while they are small.
- Check the eyes often. A 10-second look at both eyes during cuddle time or grooming makes a change easy to spot.
- Keep eyes and facial folds clean. The eye cleaning guide and the best eye wipes roundup cover the gentle way to do it.
- Act early. The sooner an eye problem is treated, the better the outlook tends to be.
Common Mistakes Owners Make
- Waiting a few days to see if it clears up. A mild red eye and an early ulcer can look alike at first.
- Agreeing to cherry eye gland removal without asking about repositioning. See the warning above.
- Calling it “just a Frenchie thing.” The researchers behind the UK data specifically warn against treating breed-related problems as normal.
- Treating tear stains and eye disease as the same thing. Stains are covered in the tear stains guide, but new redness, squinting or discharge alongside them needs a vet.
Are French Bulldog Eye Problems Genetic?
Some are, and some are not. Juvenile cataracts are linked to genetics, and inherited eye disorders usually show up in the first months of life. Many others, such as corneal ulcers, are tied to the breed’s face shape and exposed eyes. Choosing a breeder who health-tests parents helps with the first group, and careful eye checks help with the second.
Can French Bulldogs Go Blind From Eye Problems?
It can happen, usually when an eye problem is left untreated. The veterinary source above notes that ulcers left alone can lead to permanent vision loss. Prompt treatment is the best protection, which is why the same-day tier in the table above matters.
How Often Should a French Bulldog Have Its Eyes Checked?
No single schedule fits every dog. Ask the vet how often to check the eyes, and make sure every scheduled puppy visit happens. At home, a quick look at both eyes every few days is a good habit.
Can You Use Human or Leftover Eye Drops on a French Bulldog?
No. A damaged cornea can be made worse by regular eye drops, which is why a vet needs to examine the eye first, as the breeders at TomKings Kennel also point out. A Bulldog specialist also warns against putting skin fold wipes into the eye.
Why Are My French Bulldog’s Eyes Goopy or Watery?
The breed’s face shape, allergies, irritation, and infection can all be behind it. Use the discharge color table above as a first clue, and book a vet visit for yellow, green, or white discharge, or any squinting. Plain tear staining is covered in the tear stains guide.
Bottom Line
French Bulldog eye problems are common, and most trace back to the breed’s flat face and prominent eyes. Cherry eye tends to hit young dogs, ulcers become more common in adults, and conjunctivitis can strike at any age. The safest rule is the simplest one: if an eye looks red, runny, cloudy, or painful, call the vet promptly, and go the same day for squinting or a closed eye.
