The third eyelid in dogs, also known as the nictitating membrane, often causes concern for owners when it becomes visible. While its appearance can sometimes signal an underlying health issue, the third eyelid itself plays a vital role in protecting and lubricating your dog’s eyes. Understanding its function and what can cause it to become prominent is crucial for every responsible dog owner.
What is the Third Eyelid and What Does It Do?
The third eyelid is a thin, pink or whitish membrane located in the inner corner of your dog’s eye. It acts like a windshield wiper, sweeping across the eye to remove debris, dust, and other irritants. It also produces tears, contributing to overall eye lubrication and health. Normally, the third eyelid remains mostly hidden, retracting smoothly beneath the lower eyelid. You might see a tiny sliver of it, but it shouldn’t be overly noticeable.
Why is My Dog’s Third Eyelid Showing?
Several factors can cause the third eyelid to become more prominent, sometimes covering a significant portion of the eye. Some common reasons include:
- Haw’s Syndrome: This usually harmless condition is often seen in puppies and young dogs. The third eyelid protrudes, but the eye itself appears normal and healthy. Haw’s Syndrome is often related to gastrointestinal upset and usually resolves on its own.
- Dehydration: If your dog is dehydrated, their eyes can become sunken, making the third eyelid more visible.
- Injury or Irritation: A foreign object in the eye, an eye infection, or an injury can irritate the eye and cause the third eyelid to protrude as a protective measure.
- Cherry Eye: This occurs when the gland within the third eyelid prolapses, appearing as a red, swollen mass in the corner of the eye.
- Other Health Issues: More serious conditions like Horner’s Syndrome, tetanus, and certain autoimmune diseases can also cause protrusion of the third eyelid.
When Should I Be Concerned?
While a briefly visible third eyelid isn’t usually cause for alarm, persistent protrusion or other accompanying symptoms warrant a vet visit. Look out for:
- Redness or Swelling: If the eye itself is red, swollen, or producing discharge, it could indicate an infection.
- Squinting or Excessive Blinking: These can be signs of pain or discomfort.
- Changes in Eye Appearance: Cloudiness, discoloration, or a change in pupil size should be evaluated by a veterinarian.
- Lethargy or Loss of Appetite: These symptoms can accompany more serious underlying health issues.
What Can My Vet Do?
Your veterinarian will perform a thorough eye exam to determine the cause of the protruding third eyelid. They might use a special dye to check for corneal ulcers or scratches. Based on the diagnosis, treatment options can range from simple eye drops for infections to surgery for conditions like Cherry Eye.
How Can I Keep My Dog’s Eyes Healthy?
