What Are Dog Eye Boogers?

Dog eye boogers are nothing more than a buildup of mucus in the dog’s eyes. Eyes constantly produce tears but in small quantities. There are several different components in tears including mucus, water, and an oily component. Generally, this buildup of mucus isn’t even noticeable. However, in case of excessive eye discharge, eye boogers will form.

Types Of Eye Discharge And What They Mean

Clear eye discharge

Allergies usually cause this clear eye discharge in dogs.

Watery or mucus discharge

If you notice mucus or watery discharge coming from only one eye, the cause is, most likely, a foreign object. This can be a simple blade of grass, eyelash, etc.

Pus-like, yellow-green discharge

Yellow-green discharge is most commonly an indicator of a serious infection. 

Causes Of Dog Eye Boogers

There are several conditions that can cause excessive discharge, or lack of it, which in turn causes the occurrence of dog eye boogers.


Pink eye or conjunctivitis is a very common condition in dogs and humans. Conjunctivitis is an inflammation of the conjunctiva, a clear, thin tissue that lines the inside of the eyelids.

Some of the most common symptoms of conjunctivitis include:

  • Excessive blinking
  • Bloodshot whites
  • Excessive itching
  • Discharge (yellow, green)
  • Eye boogers (Crusted discharge)

Take your dog to the vet if you notice any of these symptoms.

There are many causes of conjunctivitis, some of the most common ones are:

Dry Eye

Dry eye or Keratoconjunctivitis sicca is a condition characterized by the dryness of the conjunctiva and cornea due to the lack of lubrication.

Because of the inability to properly lubricate eyes, irritants pile up inside the dog’s eye causing inflammation, infection, and other serious eye conditions.

If a dog suffers from dry eye, you will notice yellow-green discharge and the whites of the eyes turning brown.

If left untreated, dry eye can cause blindness. Therefore, it is crucial to visit the vet as soon as you notice some of the above-mentioned symptoms.

Watery Eye

A watery eye or epiphora is a condition that’s characterized by excessive tearing of the eyes.

This condition is especially common in flat-faced dog breeds, as the tear duct is not working properly and can’t control tearing.

There are many factors that can cause epiphora such as allergies, glaucoma, tear duct issues, ingrown eyelash, etc.

Of course, an excessive discharge will eventually cause dog eye boogers and other issues.

Eye Injuries

Our furry friends like to sniff and explore everything, so eye injuries are a fairly common occurrence. A foreign body or dirt can get lodged in a dog’s eye.

Whatever the cause, eye injuries are a serious issue that needs to be solved immediately. 

You will notice that something is wrong with your dog’s eye if you see excessive discharge, a bloodshot eye, pawing, or scratching at the face.

How To Recognize Something Is Wrong With The Dog’s Eyes?

Now it can be tricky to determine if there are any issues with the dog’s eyes. Obviously, dog eyes need constant lubrication to function properly. But, how to tell if a dog’s eyes are excessively wet or dry?
