Red eyes in dogs

Red eyes in dogs occur when the tissues of the eye become inflamed. This may be due to minor irritation or a serious eye disease. Because early treatment can prevent pain and protect your dog’s vision, always speak to a vet if you notice redness.

Many eye problems can cause redness. Finding the exact cause and best treatment requires a detailed veterinary examination of the eye. It helps with diagnosis if you can describe any changes you have noticed, such as discharges, cloudiness or bluing of the eye, excessive blinking or holding the eye closed.
