Boogers in dog eye

Eye boogers are a type of eye discharge. Most often, these secretions are green or yellowish in color.

Owners usually immediately determine that something is wrong with their dog’s eyes. If the boogers accumulate in the corner of the dog’s eye, and this happens every day, it is not surprising that you want to find out cause of the condition and how to get rid of it.

When You Should Warry

So-called boogers in the dog’s eyes can be symptoms of a serious problem in the animal. Before you analyze the causes of discharge from your dog’s eyes, we recommend that you familiarize yourself with the most dangerous symptoms associated with this problem.

If your dog has actually colored green eye discharge, yellow eye discharge or another colored eye discharge, schedule a veterinarian visit right away. Other signs of a potential issue consist of squinting, a red-looking eye, or if your dog is rubbing or pawing at his eye. If you believe something is incorrect with your dog’s eye, do not wait too long to make that veterinarian consultation — his eyesight might be at danger.

Causes of Eye Boogers in Dogs

If your dog has clear eye discharge, chances are good it’s triggered by allergies or something physical, like dust in the eye or wind blowing in the face. A watery discharge or mucus from one eye is frequently a sign of a foreign body, like an eyelash, while yellow-green or pus-like eye discharge could indicate a serious infection. Constantly speak to your vet to get at the root cause of your dog’s eye discharge, since some issues can result in loss of sight or loss of an eye if left unattended.


This is another possible reason for the appearance of green boogers in your pet’s eye. Mucus, yellow-green pus, or a watery eye discharge can all be signs of conjunctivitis, an inflammation of the lining of your dog’s eye. There’s a broad range of causes for conjunctivitis, from allergic reactions, injury, birth problems, and tear duct issues, to foreign matter, dry eye, distemper, and even tumors. Other signs of conjunctivitis consist of very red eyes, inflammation, blinking excessive, squinting, crusty eyes, pawing at the eyes, or keeping the eyes closed.

To treat conjunctivitis, it’s important to learn what’s triggering it. Depending upon the cause, treatment can include: eliminating the irritant and calming the area with pain medication; antibiotics and saline cleans to handle infection; surgery to treat duct issues or birth flaws; antihistamines for allergies; or other medications.

Epiphora (excessive tearing)

The cause of transparent or whitish boogers in dogs may be watery teary eye. Watery, teary eyes — resulting in stained or stinky fur and/or infected skin — can also be the result of many conditions, consisting of unusual eyelashes, inflammation, allergies, corneal ulcers if medicine is not effective, tumors, eye pain, and more.

Dealing with excessive tearing depends on what’s triggering it and may consist of: topical antibiotics or steroids for tear duct inflammation; antibiotics and topical medication for cornea damage; or surgery for duct blockage, ulcers, or irregular eyelashes.

Dry eye

A sticky, tenacious eye discharge might point to canine dry eye — a failure to produce enough eye-cleansing tears. Dry eye — symptoms can likewise consist of mucus and inflammation — might be the outcome of distemper, injury, a knock in the head near a tear-producing gland, or the body’s own immune system assaulting the tear gland tissue. Infection is a serious risk for dogs with dry eye and can cause painful, inflamed eyes. Ulcers on the cornea (surface of the eye) are also a major threat because, without the lubricating impact of tears, the eyelid can scratch the surface area of the eye simply by opening and closing.

Treatment for dry eye depends upon how severe it is and might consist of synthetic tears for numerous weeks for mild dry eye; antibiotic eyedrops to assist manage secondary infections; immunosuppressant drugs to help manage the immune system; or surgery.

This condition is brought on by excessive pressure in the eye and can be identified in a few methods, including a bulging eye or eyes, cloudy eyes, and in some cases tearing. Glaucoma causes a lot of pain; the vet might attempt to manage the ocular pressure with medications, however surgery may be suggested.

Breed problems

Discharge from the eyes of different breeds of dogs can have different intensity. Therefore, owners of some breeds may be surprised at the frequency of appearance of boogers in the eyes of their dogs.

Flat-faced dogs like pugs, Pekingese, boxers, and bulldogs can be more vulnerable to eye discharge than other breeds since their flatter faces typically mean shallower eye sockets and extending eyes.

Called brachycephalic breeds, dogs with more prominent eyes may have tear drain problems; eyelids that roll inward (entropion), triggering fantastic irritation by the lashes; or lids that don’t close completely over their eyes, a condition that can need surgery.

Breeds with loose facial skin, like bloodhounds, cocker spaniels, beagles, Saint Bernards, and some terriers, are more vulnerable to eyelids that roll outside (ectropion), as well as cherry eye, a condition that happens when a gland in the eyelid falls out of position. While antibiotics and steroids can help, surgery is typically needed for these conditions.

These are simply a few typical causes of eye discharge in dogs. Because eye problems can be an indication of brain or nerve injury, infection, or other serious issues, have your dog’s eyes inspected by a veterinarian to find out what’s behind your dog’s eye discharge.
