The eyelids act to protect the anterior surface of the globe from local injury. Additionally, they aid in regulation of light reaching the eye; in tear film maintenance, by distributing the protective and optically important tear film over the cornea during blinking; and in tear flow, by their pumping action on the conjunctival sac and lacrimal sac. The third eyelid which is seem in some animals and birds is called the nictitating membrane or haw as it is called, closes across the eye (unlike the upper and lower eyelids) and are there as extra protection for that all important eye. It is a transparent or translucent third eyelid present in some animals that can be drawn across the eye for protection and to moisten it while maintaining vision.

There are several congenital diseases, including: patellar luxation, Stenotic Nares, Cherry eye, back problems and eye abnormalities. The patella or kneecap is usually located directly in the center of the knee joint. Luxation, or dislocation of the patella, occurs when the patella slides out of its groove. Stenotic Nares is a condition where the narrow resticted nostril puts a strain on the dog's system and can lead to an enlargement of the heart. In the Cherry eye condition, the gland of the third eyelid, which produces about one-third of the tear film, prolapses as a pink fleshy mass protruding over the edge of the third eyelid, between the third eyelid and the cornea (clear front part of the eye that provides the first step in the collection of light).
