My dog's eye is red with green discharge. Is it infection or glaucoma?

Updated On September 23rd, 2025

Pet's info: Dog | Cockapoo | Female | spayed | 11 years and 5 months old | 22 lbs

My dog had her eye removed 1.5 years ago. She has been dorzolamide/timolal drops since and the pressure remained good. She is 11 , a cockapoo and had glaucoma. I refilled her meds today and she missed one day. Her eye is running, slightly green and the lower part of the eye is quite red. I also gave her some polysporin eye drops twice today. Could this be an infection or my worst fear- glaucoma in her good eye. She is not herself at all.

When a dog has glaucoma in one eye, there is an increased risk of developing it in the other eye. Now it is possible that Ella has an infection causing the symptoms you are seeing from her remaining eye, but you cannot rule out glaucoma without a vet visit. I'd recommend taking her into the vet as soon as possible to have her eye examined and treated as need. I hope this helps.

Hi . This is for Sadie... I called the vet and asked if thy will refill a script for sadies eye. Her eye ball is red and had white mucus.discharge it's been 5days for her med. still red have to get in for appoint. Does it sound like glaucoma? she
Unfortunately, without seeing Sadie in person, I can't say if she does have glaucoma or not. In order to diagnose her with glaucoma, her intraocular pressure needs to be taken with a tonometer. It is possible that if the medication isn't help her symptoms, she could have glaucoma, but again I can't say for certain without seeing her in person. I would have Sadie seen by a vet as soon as possible.

Hi, I came home tonight, and my boyfriend noticed my dog's right eye is almost completely clouded over in red. He doesn't seem to be in pain--not pawing at his eye, not wimpering, he's still letting us pet his face/head, acting happily, etc. He's 15
Based on your description I would be more worried about hemorrhage in the eye than glaucoma but either way I'd recommend having your dog seen by a veterinarian. Glaucoma usually causes redness on the white part of the eye while the rest of the eye looks cloudy or blue. Bleeding in the eye can be a sign of high blood pressure, trauma or a bleeding disorder and could lead to glaucoma if not treated promptly.

Our ship tzu dog with primary glaucoma now has a red sore on the middle of her blind eye. What can we do to help?
Ouch, poor Halie! A red lesion on the eye affected by glaucoma could indicate that her eye pressures have increased to such a level that the eye has ruptured. Please take Halie to an ER vet immediately to assess her condition, as this can be extremely painful. Aside from putting an Elizabethan/cone collar on her to prevent further injury, there isn't anything else that you can do at home at this point.

Hello, I have a German Shepard husky. I noticed yesterday his left eye had some eye boogers in the morning some were soft and green and others were hard. His eye is not oozing but does look red and irritated. Please advise. Could it be infected and
An eye infection is very likely but other conditions can cause an irritated sclera like a corneal scratch, dry eye or glaucoma. I recommend to have Ace examined by the veterinarian. The vet may stain the eye to look for a scratch. Make sure Ace is not rubbing at the eye because this could make it worse. He may need to wear an elizabethan collar. I hope this helps and that Ace gets better quickly. Please feel free to post any additional questions.

My dog as green puss coming from her eye it as only started today She is on steroids called predicure, she is 12 years old and been sprayed. It's not bothering her
It sounds as Willow is suffering from an eye infection, it is relatively common in dogs. you will need to take her to the vet the first chance you get, the vet will check the eyes, if it is indeed a simple eye infection your vet will prescribe an antibiotic eye drops that will probably solve the problem in no time.

something is wrong with my dog's eye, his left eye has changed color to a darker brown. I've taken picture with the flashes on and it doesn't look good. We've already booked an appointment for Friday but can you tell by these pictures that it could b
Based on the photos of Leo, it does not appear like a typical glaucoma. Glaucoma usually presents with a bluish hue on the cornea and the sclera (the white part) usually looks very red. There's a possibility that the photo is not showing me everything so if the doctor wants to test for glaucoma, move forward with testing. I would be worried about an infection in the eye. Depending on where you live, fungal infections are possible. Neoplasia is also a possibility. I would recommend to try to get into the vet earlier if possible. There's also a potential that you may need a referral to an ophthalmologist. I hope everything turns out alright.

my dog has green discharge from his eye and it's red and swollen how should i clean it? can i use something i use to clean my piercings with just by wiping under his eye and avoiding eye contact? i don't have salt and i don't want this to get worse.
Hi, to gently wipe your dog’s eyes you could used plain boiled water (when cooled down) or camomile tea (always cool) and clean it 3-4 times a day. I would get some money together to have him checked over as greenish discharge can be a sign of infection and with eyes t is always better to get on top of the problem sooner rather than later. Hope this helps !

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 t
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!

It sounds like he could have an eye infection or allergies. You could gently clean the discharge with a wet washcloth and then instill some artificial tears in his eyes, like GenTeal drops but he will need an antibiotic drop if he has an infection. Schedule an appointment with your vet for an examination.

My sisters dogs eye is really red and watering. She can hardly open it and she keeps blinking. I can't see anything in the eye.
She could have an infection, corneal scratch/ulcer, glaucoma, or possibly a foreign substance in her eye. She really needs to be examined by a vet to determine the cause. A vet can do a fluorescein stain to look for a scratch/ulcer on her conrea, measure the pressure of her eye, and look for signs of an infection. Once a diagnosis is made, the appropriate treatment can be started. She might need an antibiotic drop in her eye or other medications.
