If the extra lashes cause damage to the cornea or conjunctiva, it may be necessary to surgically cut out or freeze and remove the eyelash follicles. Irregularities of the eyelashes are common in some dog breeds and are probably inherited.
Inflammation of the eyelids can result from the spreading of a generalized inflammation of the skin, inflammation of the conjunctiva, local glandular infections, or irritants such as plant oils or sunlight.
Fungi, mites, or bacteria can infect the eyelids, which can then lead to a generalized inflammation. Lesions of immune-mediated diseases can occur where the skin and conjunctiva join. Pemphigus Autoimmune Skin Disorders Type II reactions occur when an antibody binds to an antigen present at the surface of its own cells. These reactions can lead to several types of diseases in dogs, including anemia, blood clotting Pemphigus is often accompanied by itching or burning sensations.
Skin scrapings, cultures, and biopsies may be required for an accurate diagnosis. Localized glandular infections may be short-term for example, a stye or longterm for example, a Meibomian abscess. When inflammation of the eyelids is caused by a generalized condition, whole-body therapy often is necessary in addition to treatment of the eye itself. Supportive therapy of hot packing and frequent cleansing is often used in severe cases. Your veterinarian will recommend a treatment program designed to control the generalized condition, make your pet more comfortable, and treat the eye condition.
Be sure you thoroughly understand the treatment program your veterinarian recommends. Do not hesitate to ask for detailed instructions regarding any eye drops or other medication you will need to give to your pet. It is often helpful to have the veterinarian demonstrate the administration of these medications.

The third eyelid is officially called the nictitating membrane and is a thin, opaque tissue that hides from view in the inner corner of the eye. They have a purpose, too. Ligaments hold this gland in place and out of sight.
But if the ligaments are weak, the gland can pop out of its normal location, looking a bit like a cherry. This condition is genetic, so it often affects both eyes. Cherry eye can be treated with a simple surgery to attach the gland back in a more normal position. They remove potentially damaging material from the surface of the eye and nourish the corneal tissues.
Dogs and cats aren't the only creatures with inner eyelids. In fact fish, polar bears, kangaroos, seals, beavers and most birds have them too, according to Bev Carter from the Metropolitan Toronto Zoo. This inner eyelid is called a nictitating nick-tit-TATE-ing membrane, and it's there for a couple of reasons. The main reason is to help keep the eyes moist. The underside of the membrane is slimy. When it slides across the front of the eyeball, it helps keep it damp.
Most creatures with these inner eyelids can choose when to move them across their eyeball. They can move this membrane across while keeping their main eyelids open. In most creatures, these inner eyelids are clear — you can see right through them.
In fact if you were to stare at a polar bear's eyes from up close, you would have trouble telling if the inner lid was across the eyes or not. For creatures such as birds and fish, the membrane helps protect the eyeball.
For birds, it protects their eyes from dust while they are flying.
