My dog's red, droopy eyes and discharge recur. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 5 years and 4 months old | 23 lbs

Hello, my dogs eyes have appeared red, and droopy. There is also what looks like a blue/grey flap around the bottom of the eyes. He has had yellow/green discharge. He hasn't shown any behavioral changes, but he has had trouble keeping his eyes open when looking up at me. I believed it might be an allergic reaction and was able to give him half a Benadryl that is comparable to the dog allergy pills. His eyes look better following it but the symptoms recur after a couple of hours. Thoughts?

Moo is adorable, but his eyes certainly seem uncomfortable given his squinting! Squinting is a sign of eye pain in dogs. Coupled with the yellow/green discharge, it is concerning that he may have an eye infection, corneal ulcer or uveitis (inflammation within the eyes). Allergies may be contributing, but the yellow/green discharge makes me suspicious that there is another issue present. If his eyes are itchy at all, make sure that Moo wears an e-collar (cone) until you can take him to the vet today or tomorrow to prevent further eye injury. I hope that all goes well!

    Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It could be allergic reaction or infectious conjunctivitis. The red and prominent third eyelids strongly suggest inflammation. You could try to use human soothing eye drops every 4-6hrs and see if that will help. However, if the eyes are bothering Jordan, if he is trying to scratch they eyes, or if there is a green/yellow discharge, you should take him to your local vets today.

    It's a little hard to see Cooper's eye in that picture. Usually discharge from just one eye can indicate a scratch on the cornea, an eye infection, uveitis, or a blocked tear duct. If he is squinting the eye, sensitive to light, tearing heavily or has any redness to the eye then he should be examined as soon as possible as this could be a scratch on the cornea or uveitis that needs to be addressed right away. Yellow or greenish discharge may indicate an infection and Cooper should be examined to decide if he needs eye drops. If it seems like everything else is normal and the discharge is mild and white in color this could be related to a blocked tear duct. In this case You can try using a sterile saline eye wash to flush his eye. However if the problem does not resolve in a day or two it would be best to have him checked out by your veterinarian. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Cooper is doing better soon!

    Hello and welcome to Petco Pet Education Center, formerly Petcoach. White goopy stuff by the eye can be just extra fluid from the eye if the eye is irritated, or the first sign of an infected eye. Yellow/green goop means bacteria and infection. If the eye is red, and if Penny is squinting or seems sore, then I recommend a visit to the vet. Eyes get either better, or much worse, very quickly. If Penny isn't not squinting and the eye is only a little bit red, you can try just natural tears for people (no medications, just eye lubrication), 6 times a day and see if it is better tomorrow. If it gets any worse at all, please see a vet right away, or if the discharge becomes yellow/green. Best of luck with Penny!

    This can be a sign of an eye infection. it can affect both the eye itself and the eyelids around it. You can keep the eye clean with saline eye wash. They typically need antibiotics and medications safe for the eye to place topically to help. Your vet can make sure there are no scratches on the cornea and provide the best medicine to clear it.
