My dog's left eye keeps having more eye discharge than usual on & off for the last week. But only one eye. Do you think he may have an eye infection?

Eye infection is one of the possibilities. However, conjunctivitis (viral or bacterial) usually affects both eyes. Excessive discharge from one eye can be related to trauma or scratch to the eyebulb, blocked up tear duct, third eyelid problem etc. If Rocco has had the discharge for the last week, you should take him to your local vet to have a full examination of the eye. That will show what is going on and the right treatment can be recommended.

    Yes, I suspect that Rocco has an eye infection. Any eye problem needs to be checked out by a vet promptly as leaving it untreated can lead to vision loss. Please take him into a vet today. I hope this helps!
