Dog Eye Discharge 2025: Vet Verified Causes, Cleaning Guide & When to Visit the Vet 🐾

By Dr. Duncan Houston BVSc

🔍 What Is Eye Discharge?

Eye discharge is a mix of tears, mucus, oil, debris, and skin cells. Normal “eye boogers” are common—but when the discharge is thick or unusual, it often signals an eye issue.

🟦 Types & What They Mean

  • Clear/watery (epiphora): Caused by tear overflow from irritation, allergies, blocked tear ducts, or breed-based tear drainage issues.
  • White/gray mucus: Often due to dry eye (KCS), where tear production decreases and mucus compensates.
  • Yellow/green discharge: Indicates possible infection—bacterial, viral, or fungal; often with redness or discomfort.

⚠️ Other Warning Signs

  • Redness, squinting, swelling, and pawing at the eye.
  • Cloudiness—could suggest corneal ulcers, cataracts, or glaucoma.
  • Pain responses—blepharospasm, rubbing against furniture.
  • Visible third eyelid or bulging eye—cherry eye, glaucoma, trauma.

🎯 Who’s More Prone?

Brachycephalic breeds (Pugs, Bulldogs, Shih Tzu, Cocker Spaniels), tear-stain breeds, and swimmers are at higher risk for eye discharge and related issues.

🔬 Diagnosing the Cause

  • Ophthalmic exam with an otoscope/ophthalmoscope.
  • Schirmer tear test for dry eye.
  • Fluorescein stain to check for ulcers.
  • Possible cytology or culture if infection or chronic discharge.

🛠️ Treatment Overview

  • Gentle cleaning with warm, damp cloth daily.
  • Topical antibiotics/antifungals or steroids for infection/inflammation.
  • Artificial tears/cyclosporine/tacrolimus for KCS.
  • Address eyelid abnormalities like entropion or distichiasis surgically if needed.
  • Manage underlying allergies or systemic conditions.

📅 Cleaning & Monitoring at Home

Step Action
1 Wash hands, use a separate clean cloth per eye
2 Soak the cloth with warm water or saline
3 Gently wipe from the inner to the outer corner
4 Apply prescribed medication, then reward
5 Note color/amount daily; call vet if worsening
