Common Dog Eye Discharge Causes

Dogs can develop eye discharge for many reasons, ranging from mild irritations to serious health conditions. Some of the most common causes include:

  • Allergies – Dust, pollen, or food allergies can trigger watery eyes.
  • Infections – Bacterial or viral infections can produce green or yellow discharge.
  • Dry Eye (Keratoconjunctivitis Sicca) – Inadequate tear production can lead to thick mucus.
  • Foreign Bodies – Dirt or debris trapped in the eye causes redness and discharge.
  • Injury – Scratches on the cornea often result in excessive tearing.
  • Blocked Tear Ducts – Poor drainage can cause constant wetness under the eyes.
  • Conjunctivitis (Pink Eye) – Inflammation of the eye lining leads to redness and goop.
  • Breed-related issues – Breeds with prominent eyes like Shih Tzus often produce more tears.
