Hello, my dog has one very red eye. It is the white of her eye that is completely red. The other eye is fine.
A red eye is quite common in dogs and there could be a host of causes.Dogs have third eyelids, which are designed to protect the eyes from foreign objects, Sometimes, bits of wood or other debris get trapped under the lid, making the eye sore and irritated. This can cause swelling and redness.When both eyes are irritated, however, it typical indicates something else. Pets with allergies, will sometimes get red eyes so if the dog has allergy's this could be the cause. In dogs, high blood pressure is also a concern. And in dogs, serious problems such as glaucoma or tumors can cause teary or mucus eyes.I suspect it is from something that has gotten into the eye and caused irritation. You can flush the eye with a eye cleaning drops found at your local pet store, and give Benadryl to help with the swelling and irritation.There are serious symptoms you should watch out for, but otherwise you can monitor her and keep the eye clean at home. Should she display the following symptoms or not improve within 72 hours it is recommended you take her to the vet.Your dogs eye seems extremely sore and irritatedThe dog has been riding in the carYour dog has been sprayed by a skunkScratching or pawing the eyesEyes have turned blue, gray, or cloudy, or the dog is having trouble getting aroundEyes are frequently bloodshot or dryThere has been a watery or discolored discharge from the eyes for 48 hours or moreYour dogs eyes are bulgingThe eyelids are swollen or unable to closeThere is a growth on the eye or eyelidOne or both pupils are dilated, or they don't respond to lightYour dog seems very sensitive to lightThe eyes are droopy or sunkenThe third eyelids are covering the lower parts of the eyesThe eyes are continually moving back and forthBlood or tiny blood vessels are visible in the center (not the whites) of the eyesThe eyelid appears to be turned inward or outwardShould she have any of the above symptoms you should get to the vet as soon as possible.
