My dog has green eye discharge and red eyes. Should I see a vet?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 11 months and 5 days old | 20 lbs

Hi, I got home yesterday and my 1 year old pup had a little green discharge coming from his eye. I wiped it and a few min later some came back. There is some there this morning too. His eye does look a tad red. Is this something I should bring him to the vet today or wait a day or two and see? Any home remedy you recommend? Thanks!

Thank you for submitting your question regarding Lincoln. I do recommend that he sees his veterinarian. With his eye being red and having green discharge, he likely has an infection. This can be a simple infection or it could be the consequence of an underlying disease. For example, a scratch across the surface of the eye is known as a corneal ulcer. This is diagnosed by placing a drop of dye on the eye. There is a also condition known as dry eye where the body does not produce adequate eye. His veterinarian can measure his tear production. Finally, he could have a foreign object such as a piece of grass trapped under his third eyelid. The treatment varies between conditions and his veterinarian will decide based on his exam and eye tests. I hope this information helps!

    Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Ocular discharge that is green or yellow tinged and mucus-like is more indicative of infection, not allergies. Discharge that occurs because of allergies is clear and watery. I recommend having Fritz seen by a veterinarian at your earliest convenience so he/she can do an eye exam and determine the best treatment for him. It is unlikely that this will resolve on its own, and eye infections can have long lasting complications. I hope this is helpful!

    Toto needs to be examined by the veterinarian within the next 24 hours. Green or yellow discharge indicates an infection. The redness also supports an infection. Dogs can get eye infections as a primary cause but they can also get an eye infection due to decreased tear production, an injury on the cornea or a foreign object stuck under the eye lid. The veterinarian will exam Toby and may recommend some diagnostics if there are indicators that something more than an infection is taking place. Make sure to protect the eye from any rubbing or scratching by having him wear an elizabethan collar. I hope this helps.

    Poor Nikko. It seems he has developed a bit of conjunctivitis and secondary bacterial infection of his cornea. If he is also sneezing then this is part of an upper respiratory infection which requires prescription antibiotics from your veterinarian to clear up. I would make it a point to schedule an appt soon for Nikko to be seen and treated for this. In the meantime make sure to clean the discharge carefully with a clean wet cloth to prevent further irritation around his eyes. I hope he feels better soon. Take care.
