Why does my dog's eye show only white when he's super chilled?

This looks normal to me. When dogs are tired or drifting off to sleep its common to see the third eyelid. When he is sitting up and awake, the normal appearance confirms this is normal. It is not cherry eye. Is he having any discharge from his eyes? If so, he may have an infection or some allergies that are making it more prominent. If he is having discharge from his eyes or they seem to be bothering him, take him in to your vet. Otherwise, there isn't cause for concern. Thanks for asking Petco Pet Education Center, formerly Petcoach!

It can be normal for the third eyelid to be slightly visible in some dogs, due to the shape of their faces and skull bones. In the photo, Ziggy's eyes look normal to me. If this is how he has always looked, and he does not have any other signs of an eye problem such as redness, squinting, or discharge, I would say that this is probably normal for him and not a reason for concern :)

It actually sounds like Oso could have facial nerve paralysis on that side that is making him unable to close his eyelid. The third eyelid is controlled by a different nerve so dogs with facial nerve paralysis will use the third eyelid to protect the eye. Facial nerve paralysis can be caused by a severe ear infection, or some neurologic diseases. I'd recommend seeing your veterinarian to see if this is a possibility. You may want to try applying an artificial tear ointment to keep his eye lubricated until you can see your vet

The skin over the eye is a third eye lid - it often comes up with eye infection, fever or when generally dogs are unwell. Please, take your dog to your vet and get him examined. He may have eyes or upper airways infection and he will need a course of antibiotics to get better.

A closed eye is often a painful eye, and a painful eye should be seen by a veterinarian. A scratch or ulcer of the cornea is the most common reason I see this, although many other problems can cause it as well. Good luck and I hope he improves soon.

What you are seeing on Jax is his third eyelid (known as the nicitating membrane) sticking out over the rest of his eyeball. I can not say for sure why it has prolapsed. This can happen due to an injury or an infectious process. The nicitating membrane has several important responsibilities, so making sure that it is still fully functional is important. While it is not an emergency, if the membrane does not return to its normal location by tomorrow I would consider bringing Jax in for an appointment. In the mean time, I would recommend obtaining some artificial tears from the drug store and keeping the eye nice and lubricated. Do this every 4 to 6 hours in case there is a lack of tear production.

It looks like Ginger’s third eyelids are elevated. This can happen if the eyes are irritated or if there is a neurologic problem. I would recommend having your vet check her eyes if it is persistent.
