How long does it take to repair a dog corneal ulcer?

It depends on the severity and medical treatment. Generally speaking, mild keratitis can be cured in one to two weeks, while severe keratitis may take two months or more. Nothing will get better. Keratitis is mainly caused by external force. Common ones such as inverted eyelashes, sand entering, or accidentally hitting the eye will cause keratitis. Mild keratitis looks like a white turbidity on the eye. In this case, you can consult a doctor, get some eye drops and apply them to your dog on time, and it will basically recover in about two weeks.
