Why Do Dogs Get Eye Boogers?

What are some of the potentially dangerous symptoms to look out for?

Some eye discharge in dogs is completely normal, but yellow discharge or pus could indicate a serious infection.

Here’s four common causes of eye discharge in dogs.

1. Entropion

Entropion is a genetic condition where a portion of the eyelid is folded inward. Hair can rub against the cornea, eventually leading to corneal ulceration and vision impairment. 

If you see your dog squinting with excessive tears and mucus discharge from the outer corners of the eye, take your dog to the vet.

2. Epiphora

Ephiphora is another condition that causes an overflow of tears from the eyes.

Common signs are wetness around the eyes and a reddish or brown staining on the fur.  It’s a good idea to take them to a vet to determine what the underlying cause is.

3.  Keratoconjunctivitis sicca

Also known as canine dry eye, this condition is caused by inadequate tear production. Some of the common conditions leading to this include hypothyroidism and immune disorders that damage the tear producing glands.

4. Conjunctivitis

Viral infections, trauma, environmental pollutants can cause this form of pink eye which is inflammation of the tissue that covers the front part of the eyeball and eyelids. Redness, swelling and discharge is usually apparent with this infection.
