Red Eyes in Dogs: What It Means

Red eyes in dogs, also known as conjunctival%20hyperemia, is a common sign that indicates inflammation or irritation of the eye. It's important to pay attention to this symptom as it can point to a range of underlying issues, some of which require veterinary attention. Here's a breakdown of potential causes and what to look for:

  • Conjunctivitis: This is inflammation of the conjunctiva, the pink membrane that lines the inner eyelids and covers the white part of the eye. Causes can include allergies, bacterial or viral infections, irritants (like dust or smoke), or foreign objects.

  • Dry%20Eye%20(Keratoconjunctivitis%20Sicca): This condition occurs when the tear glands don't produce enough tears, leading to dryness, irritation, and inflammation of the cornea and conjunctiva.

  • Glaucoma: Glaucoma is characterized by increased pressure inside the eye. Redness can occur because the pressure affects blood flow and irritates the eye. This is a serious condition that can lead to blindness if left untreated.

  • Uveitis: This refers to inflammation of the uvea, the middle layer of the eye which includes the iris, ciliary body, and choroid. Uveitis can be caused by infection, trauma, or autoimmune diseases.

  • Corneal%20Ulcers: A corneal ulcer is an open sore on the cornea (the clear front part of the eye). These ulcers are painful and often cause redness.

  • Foreign%20Object: A foreign body, such as a grass seed, can cause irritation and redness.

  • Injury/Trauma: Any kind of injury to the eye (scratch, blunt force trauma) can cause redness.

When to see a vet:

It is important to consult a veterinarian if your dog has red eyes, especially if it's accompanied by:

  • Discharge (pus, mucus, or excessive tearing)
  • Pawing at the eye
  • Swelling around the eye
  • Cloudiness of the eye
  • Changes in vision
