Corneal ulcers are painful eye injuries that can rapidly progress to vision loss or eye rupture if not treated promptly. Recognizing the signs and seeking immediate veterinary care are essential for dog welfare.
Corneal ulcers cause severe, acute pain comparable to the most painful conditions in veterinary medicine. Dogs in pain from corneal ulcers are visibly distressed — blinking continuously, pawing at the eye, and refusing to open it. The high pain receptor density makes even small ulcers intensely painful. Many owners underestimate the pain severity, delaying treatment. Brachycephalic breeds are particularly vulnerable to ulcers and to complications including melting ulcers that can cause complete corneal destruction within 24 hours. Adequate analgesia using atropine (which relieves ciliary spasm) alongside topical antibiotics is essential — treating infection without addressing pain is insufficient. Most simple ulcers heal within 5-7 days with appropriate treatment; deep or complicated ulcers require specialist ophthalmological care.
