What to do about my dog's green eye discharge? Old meds or saline?

Updated On September 23rd, 2025

Pet's info: Dog | Great Pyrenees | Male | neutered | 75 lbs

My dog has a green, dry eye mucus stuck to the corner of his eye. It doesn't look actively mucusy, but i know i saw a little mucus that i wiped away last week in the same eye. What could this be? He was prescribed neomycin polymyxin b sulfates and dexamethasone ophthalmic ointment a few months ago. Can i use this on his eye to help? Should i clean out the eye with saline? Thank you

It sounds like Falkor may have an eye infection. You can gently clean the eye out with saline, but I would not use those medications you have on them. Legally, I cannot say if it's safe to use them on Falkor because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for your dog. They could also be the wrong drug for his condition, and they could be expired. His eye does need to be examined by a vet, which can let you know if it's safe to use those medications, or can prescribe him new ones. I would have him seen by a vet right (and bring the meds with you), as any eye condition should be considered an emergency (leaving them untreated can lead to vision loss).

    It would be important to have his eye examined prior to using that ointment. The product you have contains a steroid which is great for cases of conjunctivitis and inflammation but is contraindicated with a corneal ulcer. It is likely NOT a corneal ulcer but a steroid can make an ulcer penetrate full thickness in the cornea if used.
