Conjunctivitis, the inflammation of the conjunctival membranes of the eye, is common in dogs. This may involve one or both eyes and be acute or chronic in nature. Clinical signs include the eye(s) appearing red and injected, there may be swelling to the conjunctiva and a discharge ranging from clear and thin to thick and green/yellow will be present. The eyes may be painful with the dog keeping the eye partially closed and exudates may form crusts around the eyelids.
