Dog Eye Discharge: What It Means

Some discharge is normal

A small amount of clear or slightly gray matter in the corners, especially after sleep, is usually normal tear drainage. Certain breeds with flat faces or loose lids naturally produce more. The concern is a change in amount, color, or comfort.

Reading the color and texture

Watery, clear discharge can come from irritation or allergies, while thick yellow or green discharge suggests infection. Excessive tearing may signal blocked ducts, and reddish-brown tear stains are common in light-coated dogs. Any discharge with squinting or redness deserves attention.

Warning signs to watch

Squinting, pawing at the eye, cloudiness, redness, swelling, or holding the eye shut can indicate pain, injury, or conditions like conjunctivitis or glaucoma. Sudden changes in vision are urgent. Eyes are delicate, so err on the side of caution.

Gentle home care

For mild, occasional discharge, wipe the area with a clean, damp cloth, moving away from the eye, and keep the surrounding fur trimmed. Never use human eye drops or medications unless your vet directs you to. Keep irritants like dust and smoke to a minimum.

When to call the vet

See your vet promptly for thick colored discharge, pain, redness, cloudiness, or any change in vision, and treat sudden severe eye problems as an emergency. Early care can protect your dog's sight. Recurrent discharge also warrants a workup for the cause.
