Squinting and Inflamed Eyelids in Dogs
Foreign Bodies in the Eyes continued...
You may be able to see dirt or plant material on the surface or behind the
upper and lower eyelids. If not, the foreign body may be caught behind the
third eyelid. In that case, the dog will need a topical eye anesthetic before
it can be removed.
Treatment: Flush the eye for 10 to 15 minutes using cool water, or
preferably a sterile saline eyewash or artificial tears. To flush the eye, soak
a wad of cotton in the solution and squeeze it into the eye repeatedly. If you
have a bottle of artificial tears on hand, you can flush the eye directly from
If the foreign body cannot be removed by irrigation, you may be able to
remove it by gently touching it with a wet cotton-tipped swab. The foreign body
may adhere to the cotton tip. Foreign bodies that penetrate the surface of the
eye must be removed by a veterinarian. Restrain the dog from pawing at the eye
while you drive to the veterinary hospital.
If the dog continues to squint or tear after the foreign body has been

This condition, in which the eyelids roll inward, is the most common
congenital defect of the eyelids. It can also be caused by injury and long-standing eyelid
infections that cause scarring. The abnormal eyelids produce irritation with

It may be difficult to distinguish entropion from blepharospasm. The best
way to tell them apart is to administer a topical eye anesthetic. If the
inverted eyelids are caused by blepharospasm, temporarily blocking the eye pain
causes the inversion to disappear.
Breeds most commonly affected by entropion are the Chinese Shar-Pei, Chow
Chow, Great Dane, Great Pyrenees, St. Bernard, Bulldog, and the hunting breeds.
Most cases involve the lower eyelids. In dogs with large heads and loose facial
skin, such as Chinese Shar-Pei, Bloodhounds, and St Bernards, the upper eyelids
may be involved.
Treatment: Entropion requires surgical correction. Note that dogs who have
had corrective surgery on their eyelids cannot be shown in conformation.
