Dog Corneal Ulcer Emergency Care

Corneal ulcers are painful eye emergencies in dogs that can progress to perforation within days without treatment, requiring prompt veterinary attention.

Key Facts

Corneal ulcers involve loss of the outer epithelial layer of the eye
Trauma, dry eye (keratoconjunctivitis sicca), and entropion are common causes
Brachycephalic breeds are highly predisposed due to prominent globes and lagophthalmos
Melting ulcers from Pseudomonas infection can perforate the eye within 24-48 hours
Fluorescein stain confirms ulcer presence and depth
Topical antibiotics, atropine for pain, and an e-collar are initial management essentials
Surgical options including conjunctival grafts save perforated or deep ulcers
Indolent ulcers in Boxers require debridement to enable healing

Welfare Considerations

Corneal ulcers cause intense, constant pain - the cornea is among the most densely innervated tissues in the body. Affected dogs squint, tear excessively, and rub their eyes compulsively. A perforated globe is a welfare catastrophe requiring emergency surgery under anesthesia. The rapid progression of melting ulcers from minor injury to perforation within days means owner recognition and immediate veterinary evaluation is genuinely time-critical. E-collar compliance is essential for recovery - removal allows self-trauma that can cause perforation of even a healing ulcer.

What You Can Do

Seek same-day veterinary evaluation for any dog squinting or pawing at an eye
Maintain strict e-collar compliance throughout corneal ulcer treatment
Keep topical medications refrigerated and administer at the prescribed frequency
Ask about referral to a veterinary ophthalmologist for deep, infected, or non-healing ulcers
Address underlying causes like dry eye and entropion to prevent recurrence
