Besides the two usual lids of the eye as humans have, canines have a third eyelid that rests just under the lower lid. The third eyelid contains a gland that secretes fluid to keep the dog’s eyes moist.
Usually, this third eyelid is completely invisible. It can only be seen when some condition is causing it to lift above the other lid. Irritation and infection of this eyelid can cause it to swell and become visible as red, inflamed tissue on the eye – a condition called conjunctivitis. Your veterinarian will prescribe an antibiotic ointment to eliminate the bacteria and return your dog’s appearance to normal.
Foreign Object in Eye
This is one dog eye problem that has no direct herbal remedy. Dogs may get tiny bits of material stuck in their eyes when they run through brambles or hang their heads out of car windows. The dog’s eyes may water and make him blink, squint and paw at the sockets.
If you can see the object when you hold your dog’s eye open, try to pick it out with a tissue or tweezers. It is often easier to simply flush the eye with a saline solution made for eyes, or with purified water. If this doesn’t remove the object, make an appointment with the veterinarian to get an accurate diagnosis, treatment and medication if necessary.
Allergic Eye Reactions
Like humans, dogs may develop allergies to substances in their environment that cause their bodies to produce a reaction. Allergens that can affect your dog include tree pollen, grass pollen, weed pollen, molds and mildew.
Some animals show allergic reactions to strong household cleaners. Food allergies can also cause reactions. These dogs may develop watery eyes, squinting, constant rubbing at the eyes and discharge from the eyes.
Eye Growths and Tearing
Occasionally, dogs will develop growths around and in their eyes. These problems usually occur with older dogs but may also affect younger animals. Your veterinarian should diagnose the problem to determine what type of treatment is necessary. In some cases your vet may recommend surgery to prevent the dog’s vision from being hampered by the growth.
