My dog has thick, yellow-green eye discharge. Is it an infection?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 15 years and 11 months old | 8 lbs

Zoey has a clear liquid draining from her eye. It is almost like a tear but slightly thicker. It has been happening for three days now and has spread to the other eye. It is sometimes even thicker and yellow/green. It doesn’t seem to bother her at all. No other symptoms. I’m wondering if it is just allergies or something more serious like an infection. She is older and has had UTIs (twice in the past year and a half).

It sounds like to me it could be an infection. Any eye problem needs to be checked out by a vet promptly as leaving it untreated can lead to vision loss. I'd take Zoey into a vet today. Best of luck.
