Why Are My Dog’s Eyes Red?

Seeing your furry friend with red eyes can be alarming. It’s natural to worry about their health and well-being. Red eyes in dogs can be caused by a variety of factors, ranging from minor irritations to serious conditions. This article will guide you through the potential causes, symptoms, and necessary steps to address your dog’s red eyes.

Understanding the Causes of Red Eyes in Dogs

Redness in a dog’s eyes can indicate several issues, including:

  • Conjunctivitis: Inflammation of the conjunctiva, the thin membrane that lines the inside of the eyelids and covers the white part of the eye.
  • Dry Eye: This condition, also known as keratoconjunctivitis sicca (KCS), occurs when the tear glands produce insufficient lubrication.
  • Allergies: Environmental allergens, such as pollen, dust, and mold, can trigger allergic reactions that manifest as eye redness, itching, and discharge.
  • Eye Infections: Bacterial or viral infections can cause inflammation, discharge, and discomfort.
  • Glaucoma: This condition involves increased pressure inside the eye, which can lead to vision loss if untreated.
  • Uveitis: Inflammation of the uvea, the middle layer of the eye, which contains the iris, ciliary body, and choroid.
  • Foreign Object: A foreign body, like a piece of grass or dirt, lodged in the eye can cause irritation and redness.
  • Injury: A scratch, puncture, or other injury to the eye can result in redness and pain.
