Quick answer: Puppies often get mild eye discharge from irritants, allergies, or conjunctivitis, sometimes linked to respiratory infections. Young dogs can also have eyelid problems like entropion, extra eyelashes, and cherry eye, which are common in certain breeds. Newborn puppies whose eyes haven’t opened can develop infections behind the eyelids. Any eye discharge lasting more than a day, squinting, or cloudiness in a puppy should be checked.
Common eye problems in puppies
- Conjunctivitis: red eyes and discharge, sometimes with a cough or sneeze
- Entropion: eyelids rolling inward and rubbing the eye (common in Shar-Peis, Chow Chows, and others)
- Abnormal eyelashes that rub the eye
- Cherry eye: a red swelling in the inner corner
- Neonatal infections: swelling or discharge behind still-closed eyelids in newborns (needs a vet)
- Inherited eye diseases: some breeds are screened for these by veterinary ophthalmologists
Safe home care
- Gently wipe discharge with sterile saline on a cotton pad, a fresh pad per eye
- Keep hair trimmed away from the eyes
- Prevent rubbing
When to see a vet
- Discharge lasting more than a day
- Squinting or pawing at the eye
- Cloudiness
- Swollen eyelids in newborn puppies
What to avoid
- Human eye drops
- Waiting on a squinting eye, which may be an ulcer
