This is the condition where French Bulldog owners most often make a costly mistake, and the mistake is waiting until morning.
Why speed matters here
A superficial ulcer treated on day one is a course of drops and a buster collar. The same ulcer left for three days, in a dog with reduced corneal sensitivity that keeps rubbing it, can become a melting ulcer — where enzymes actively digest the corneal stroma — and progress to perforation. The gap between an inexpensive treatment and losing the eye is measured in days.
The buster collar is the treatment
Owners hate them and remove them, and it is the single most common reason a treatable ulcer becomes a surgical one. A dog that can reach its own eye will rub it, because it hurts. The collar stays on continuously, including indoors and overnight, until the vet confirms the ulcer has healed.
Signs to look for
- Sudden squinting or holding the eye closed
- Watery or sticky discharge
- Cloudiness or a visible dull patch on the surface of the eye
- Redness and obvious pain
- Rubbing the face persistently
What causes it
- Prominent, exposed eyes with limited protection
- Incomplete blink leaving part of the cornea dry
- Reduced corneal sensitivity, so minor trauma is not felt and not protected against
- Entropion or distichiasis causing mechanical abrasion
- Reduced tear production
How it is diagnosed
Fluorescein staining shows the extent and depth of the ulcer. Depth is what determines urgency — a deep or melting ulcer is a same-day surgical problem.
Treatment options
- Topical antibiotic drops and pain relief for superficial ulcers
- Serum eye drops for melting ulcers
- A buster collar, non-negotiably, to prevent self-trauma
- Surgical intervention — grid keratotomy, conjunctival graft or corneal repair — for deep or non-healing ulcers
- Correction of any underlying entropion
Reducing the risk
- Treat any squinting as urgent rather than waiting overnight
- Correct entropion and distichiasis promptly
- Keep long-haired toys and rough play away from the face
- Use lubricating drops in dogs with a known incomplete blink
Insurance: Ulcers are usually covered as accidental or acquired conditions, but repeat ulceration in the same eye can be reclassified as a recurrence of a single ongoing condition rather than fresh incidents — which matters against a per-condition limit.
What we would actually buy
Lifetime cover with per-condition limits that hold up against a single IVDD surgical episode. Compare the per-condition limit rather than the headline annual figure.

Common questions
Is a corneal ulcer in a French Bulldog an emergency?
Yes, effectively. Any sudden squinting, cloudiness or reluctance to open an eye warrants a same-day appointment. Ulcers in this breed can deepen alarmingly quickly.
Why do French Bulldogs get so many eye ulcers?
Prominent eyes with shallow orbits, an often-incomplete blink that leaves part of the cornea drying, and reduced corneal sensitivity so the dog does not react protectively to minor trauma. The combination is unusually unfavourable.
