How long does it take to cure a dog’s blue eye disease?

With active treatment, a dog’s blue eye disease can recover in about a month. It is usually caused by infectious hepatitis, an acute infectious disease whose signs include corneal edema, opacity, and a bluish cornea, generally returning to normal in about a month with treatment. However, a blue cornea can also result from trauma or other causes, so when noticed, the owner should take the dog to a veterinary hospital to confirm the cause and apply correct treatment.
