Dog Red Eyes

Dog Red Eyes: Causes, When to Worry, and When to Seek Care

Red eyes in dogs can be a sign of irritation, injury, or an underlying medical condition. While mild redness may sometimes resolve on its own, persistent or worsening redness should not be ignored.

Because eye issues can progress quickly, it’s important to recognize when your dog’s red eyes may require veterinary care.

Common Causes of Red Eyes in Dogs

Red eyes are usually caused by inflammation or irritation affecting the eye or surrounding tissues. Common causes include:

  • Allergies (environmental irritants like pollen or dust)
  • Conjunctivitis (pink eye)
  • Eye infections (bacterial or viral)
  • Foreign objects in the eye (dust, debris, grass)
  • Dry eye (keratoconjunctivitis sicca)
  • Corneal ulcers or scratches
  • Trauma or injury to the eye
  • Glaucoma (increased pressure within the eye)

Some causes are mild, while others can threaten vision if left untreated.

When Should You Be Concerned?

While mild redness may not always be urgent, certain signs indicate your dog should be evaluated by a veterinarian.

You should seek care if your dog:

  • Has persistent or worsening redness
  • Is squinting or keeping the eye closed
  • Has discharge (especially yellow, green, or thick)
  • Is pawing at the eye or rubbing their face
  • Has cloudiness or visible changes in the eye
  • Is sensitive to light
  • Has swelling around the eye

If your dog appears to be in pain or has sudden vision changes, this should be treated as urgent.

How We Diagnose Red Eyes in Dogs

At L&L Animal Urgent Care, we evaluate red eyes by identifying the underlying cause and assessing the health of the eye.

Diagnostics may include:

  • Thorough eye examination
  • Fluorescein stain test to check for corneal ulcers
  • Evaluation for foreign objects or trauma
  • Tear production testing (for dry eye)
  • Measurement of eye pressure if glaucoma is suspected

Our goal is to diagnose the issue quickly and protect your dog’s vision.

Treatment Options

Treatment depends on the cause of your dog’s red eyes.

Common treatments may include:

  • Eye drops or ointments for infections or inflammation
  • Removal of foreign objects
  • Medications to relieve pain or irritation
  • Treatment for allergies
  • Management of underlying conditions such as dry eye or glaucoma

Prompt treatment is important to prevent complications and preserve vision.
