It’s important to know what type of eye injury your dog may have. These are the 9 most commonly seen eye disorders in dogs.


  1. Conjunctivitis: One of your dog’s eyes will look red and swollen, and there may be discharge.

  5. Glaucoma: The cornea becomes cloudy and the eye enlarges due to increased pressure in the eyeball.

Common symptoms of eye disorders:


  1. Discharge or crusty eye gunk
  2. Tearing
  3. Red or white eyelid linings
  4. Tear-stained fur
  5. Closed eye/s
  6. Cloudiness or change in eye colour
  7. Visible third eyelid/s
  8. Unequal pupil sizes


When you first notice these signs, try to clean your dog’s eyes gently with a clean, damp cotton ball. Wipe outward from the corner of the eye and be careful not to touch his or her eyeball – you don’t want to scratch the cornea. If the irritation persists, take your dog to his or her vet immediately.
