14. Dogs Have Three Eyelids
A little-known characteristic of dogs is the presence of a third eyelid, called the nictitating membrane.
This additional eyelid serves to protect the eyes from dirt, dust, and injuries, as well as to keep the eye surface lubricated.
It is particularly useful for dogs that engage in activities in windy or dusty environments, representing another of the “Curiosities About Dogs.”
The nictitating membrane becomes visible when a dog is relaxed or when something irritates its eyes, like dust or a foreign object.
It works like a “windshield wiper,” removing debris and spreading a protective film over the eyes. This structure supports dogs’ eye health, helping to prevent infections and injuries.
Owners should monitor this eyelid, as it can sometimes indicate health problems. If the third eyelid is constantly visible or discolored, it may signal an infection or other eye issue. In such cases, veterinary guidance is recommended to ensure the dog’s eye health.
