Hi Shani:
This symptom can be a localized infection of the eye (now spread) or can be an indication of a more wide spread "systemic" problem. He needs an exam. I would think that exam and treatment would not be too expensive.
Eye wash may help, but only to remove the discharge, and not get to or solve the underlying infection or problem. Eye drops or ointment are not expensive and you may get him over this quickly and inexpensively.
But I will say, the eyes are not to be neglected! Disease or infection can hurt those delicate tissues quickly and sometimes permanently. My suggestion is to get him in!
Thanks - I am going to call the Vet and see what we can do about Hershey. Thanks for the answer.
