Corneal Ulcers in Dogs: Welfare and Treatment 2026

Corneal ulcers are painful eye conditions in dogs that can rapidly progress to severe complications if not treated promptly.

Key Facts

Corneal ulcers can be caused by trauma, foreign bodies, eyelid abnormalities, or breed-related conformational issues
Brachycephalic breeds such as Pugs, French Bulldogs, and Bulldogs are predisposed due to prominent eyes
Superficial ulcers usually heal within 5-7 days with appropriate treatment
Deep or infected ulcers can progress to perforation and loss of the eye within days if untreated
Indolent ulcers in older dogs fail to heal despite treatment and require specific surgical debridement

Welfare Considerations

Corneal ulcers cause acute, significant pain - the cornea is one of the most densely innervated tissues in the body. Dogs with corneal ulcers frequently squint, paw at their eye, and show photophobia. Untreated ulcers can progress to perforation, iris prolapse, and permanent vision loss within days, making prompt veterinary assessment critically important. In brachycephalic breeds, recurrent corneal trauma from exposure keratopathy is a chronic welfare issue linked to the exaggerated conformation that produces prominent, poorly-protected eyes. Eyelid surgery to improve coverage substantially reduces recurrent ulceration in these breeds.

What You Can Do

Seek same-day veterinary assessment for any dog squinting or pawing at its eye
Do not attempt to treat eye problems at home - corneal conditions can deteriorate rapidly
Consider conformation surgery for brachycephalic dogs with recurrent corneal problems
Support legislation requiring health testing for brachycephalic breeds to reduce conformational welfare issues
