Dog Eye Boogers: Causes, Treatments, and When to See a Vet

Sep 15, 2025

Author:Amanda Lyu

Did you ever see crusty bits in the corners of your dog? They are also known as dog eye boogers, and they are not that rare. The majority of dogs acquire them just as human beings do, by waking up with some eye gunk.

Eye boogers normally occur when the tears are combined with dust and dry around the eye. It is a natural eye-cleaning process for your dog.

Want to know what really causes these eye boogers and how to keep your dog’s eyes healthy? Let’s dig in.

What Are Dog Eye Boogers and Are They Normal?

Dog eye boogers are a mix of tears, mucus, and tiny bits of dirt or dust. Your dog’s eyes make tears to keep the eyes clean and moist. As these tears dry up, they form a little crust or goo we refer to as eye boogers. This is normal and happens to almost all dogs.

In the majority of cases, a little bit of eye discharge is not something to be concerned about. It usually appears when your dog is asleep, just like people get sleep in their eyes. You can just wipe it carefully, and your dog is okay.

However, when the boogers appear differently, such as green, yellow, thick, or even when they reappear all day, then it might signal that something is wrong. It could be allergies, dog dry eye, or even an infection requiring the attention of a vet.

Common Causes of Dog Eye Boogers

There are a few reasons why dogs get eye boogers. Some are normal, and some mean your dog needs help. Here are the most common causes:

1. Normal Tear Drainage

Dogs make tears all the time. These are tears that keep the eyes healthy. When tears dry, they can form a small crust on the eye. It is natural and can be cleaned at home.

2. Allergies and Dust

Dogs, too, can be allergic just like humans. Their eyes can get watery due to things such as pollen, smoke, and dust. This may lead to more eye boogers. When your dog is scratching and sneezing frequently, this may be due to allergies.

3. Eye Infections

If you see green or yellow discharge, it could be an infection. Eye infections need quick treatment. Do not wait too long because it can hurt your dog’s eyesight. This is when dog eye boogers treatment becomes very important.

4. Dry Eye in Dogs

Some dogs have dry eye, also called Keratoconjunctivitis Sicca. This means their eyes do not make enough tears. Dry dog eyes can lead to sticky, thick boogers. Your vet can give medicine to help.

Eye boogers can also sometimes be a symptom of a more serious condition, like a corneal ulcer or blockage of the tear duct. You should go to the vet as soon as you see swelling, redness, or pain.

How to Treat Dog Eye Boogers at Home

You can safely treat most dog boogers in the eye at home with simple cleaning and care. Here's how:

Safe Cleaning Methods

Clean the eyes of your dog using a soft and damp cloth or pet wipes. Wipe it off, but do not rub it too hard. Never apply harsh chemicals or baby wipes, as this will irritate the eyes of your dog.

How to Soften Dog Eye Boogers Before Cleaning

If the discharge is dry and stuck, don’t pull it off. Instead, make it soft first. It can be achieved by putting a warm and damp cloth on top of the eye for a few seconds. This softens the boogers and makes it easy and painless to clean.

You can also use safe eye wipes made for pets. Stay away from human products; they are not safe for dogs. This is the best method if you’re wondering how to soften dog eye boogers.

Over-the-Counter Solutions

In case your dog is irritated mildly, then you can use a pet-safe saline solution to wash the eyes. These are gentle and help keep the eyes clean. Never use human eye drops because they can harm your dog’s vision.

Dog Eye Boogers Treatment for Different Causes

The best dog eye boogers treatment depends on the reason behind them. Here are some common causes and how they are treated:

Allergies: If allergies are making your dog’s eyes watery and crusty, the vet may suggest antihistamines. Do not administer human medicine at home since it may be dangerous. Always take precautions prescribed by your vet concerning allergy care.

Infections: Green or yellow discharge is a common sign of an eye infection. Your vet will give antibiotic drops or ointment to clear the bacteria. In some cases, oral medication is needed if the infection is severe.

Dry Eye: Dogs' dry eye (Keratoconjunctivitis Sicca) requires artificial tears or special medicines in order to make more tears. This can become more serious without treatment, so do not delay visiting the vet.

When Should You See a Vet for Dog Eye Boogers?

Most eye boogers are harmless, but some need quick vet care. Call your vet if you notice:

● Persistent green or yellow discharge: This often means infection.

● Swelling, redness, or pain: If your dog continues to paw at the eyes or the eyes appear sore.

● Behavior changes: If your dog stops eating, becomes weak, and continues to rub its eyes, it is a red flag.

How to Prevent Dog Eye Boogers

Keeping your dog’s eyes healthy is easier than you think. Here’s what you can do:

● Regular cleaning and grooming: Clean the eyes of your dog with a towel. Cut hair around the eyes to avoid it poking them or irritating them.

● Balanced diet for eye health: A Healthy diet keeps eyes healthy. Ensure that your dog consumes a diet that is rich in minerals and vitamins.

● Keeping your dog well-hydrated also supports healthy eyes. A dog water fountain encourages your pup to drink more and stay refreshed all day.

● Regular playtime also reduces stress, which can sometimes worsen eye issues. Explore fun and safe toys for dogs to keep your furry friend active and healthy.

Healthy eating is a big part of eye care. WOPET Smart Feeders make it easy to give your dog the right meals every time.
