Conjunctivitis, also known as pinkeye or red eye, is as common in dogs as it is in humans. It’s an itchy inflammation of the tissue that coats the eye, called the conjunctiva.

Conjunctivitis can happen at any age, by itself or because of another eye problem.

While just one eye is typically affected, conjunctivitis can spread to both.

Symptoms

  • Redness
  • Puffy eyelids
  • Stringy discharge
  • Watery eyes
  • Pawing at his eyes
  • Squinting
  • Eyelids that stick together

At the first sign of these symptoms, it’s best to take your dog to the vet. He can tell what type of conjunctivitis you’re dealing with and how to treat it. Plus it may be a more serious condition that could cause blindness if left untreated.
