Corneal ulcers are extremely painful eye conditions in dogs that cause acute and chronic welfare suffering and require prompt veterinary treatment to prevent vision loss and manage pain effectively.
Corneal ulcers cause severe, continuous pain that profoundly impairs welfare. Dogs with active corneal ulceration cannot open the affected eye comfortably, are distracted by pain from normal activities, and sleep poorly. The pain from corneal damage is among the most intense of any ocular condition — dogs with unmanaged corneal ulcers are in genuine acute distress. Systemic pain management (NSAIDs or opioids for severe cases) alongside topical treatment is essential — topical antibiotics alone do not address the significant pain burden. Elizabethan collars prevent self-trauma but are themselves sources of stress, requiring welfare balancing. Brachycephalic breed owners should be aware of their dog's elevated ulcer risk and check eyes regularly for early signs.
