Why Are My Dogs Eyes Turning Blue


Noticing changes in your dog’s eyes can be concerning, especially when they start turning blue. You might find yourself asking, “Why are my dogs eyes turning blue?” This transformation can be indicative of various underlying conditions, some of which require prompt attention. Understanding the potential causes and associated concerns is crucial for ensuring your dog’s health and well-being. This article will guide you through the possible reasons behind this eye color change, what it means for your furry friend’s health, and the steps you should take to address it. Recognizing and addressing these changes early can make a significant difference in your dog’s quality of life.

Why Are My Dogs Eyes Turning Blue?

Dogs’ eyes can exhibit a range of colors, typically from brown to amber, and sometimes blue. However, a sudden change in eye color, such as your dog’s eyes turning blue, can be alarming. It’s important to distinguish between natural variations and signs of potential health issues.

When considering why your dog’s eyes are turning blue and cloudy, it’s essential to understand the difference between normal and abnormal changes. Puppies of certain breeds, like Siberian Huskies, naturally have blue eyes which can remain blue throughout their lives. However, if an adult dog’s eyes suddenly turn blue or develop a cloudy appearance, it could be a sign of an underlying problem.

Conditions such as cataracts, nuclear sclerosis, glaucoma, and corneal dystrophy can cause significant changes in the appearance of your dog’s eyes. Understanding these conditions and how they impact your dog’s vision is the first step in addressing and managing their eye health.

Common Causes of Blue and Cloudy Eyes in Dogs

If you’re wondering, “Why are my dog’s eyes turning blue and cloudy?”, it’s essential to be aware of the various potential causes. Here are some of the most common reasons behind this change in eye appearance:


  • Cataracts are characterized by a cloudy, opaque area in the lens of the eye. This condition can cause a blue or grayish tint, making your dog’s eyes look cloudy.
  • Cataracts can be hereditary or result from diabetes, aging, or trauma.
  • Symptoms include difficulty seeing, bumping into objects, and changes in pupil appearance.

Nuclear Sclerosis

  • Nuclear sclerosis is an age-related change that affects the lens of the eye, leading to a bluish-gray haze.
  • Unlike cataracts, nuclear sclerosis does not significantly impair vision.
  • It is common in older dogs and is often mistaken for cataracts due to the similar appearance.


  • Glaucoma is a condition characterized by increased pressure within the eye, which can lead to a bluish tint and cloudiness.
  • Symptoms include redness, pain, excessive tearing, and vision loss.
  • Glaucoma requires immediate veterinary attention to prevent permanent damage to the optic nerve.

Corneal Dystrophy

  • Corneal dystrophy is a hereditary condition affecting the cornea, leading to cloudiness and a bluish tint.
  • It typically affects both eyes and can cause vision impairment.
  • There is no cure for corneal dystrophy, but treatments can help manage symptoms and slow progression.


  • Uveitis is inflammation of the uveal tract (the middle layer of the eye), which can cause a cloudy and bluish appearance.
  • Causes of uveitis include infections, trauma, immune-mediated diseases, and cancers.
  • Symptoms include redness, pain, squinting, and excessive tearing. Uveitis requires prompt veterinary treatment.

Infections or Injuries

  • Eye infections or injuries can lead to inflammation and cloudiness, sometimes resulting in a blue hue.
  • Bacterial, viral, or fungal infections, as well as physical trauma, can cause these changes.
  • Symptoms may include discharge, redness, swelling, and squinting. Immediate veterinary care is crucial to prevent complications.

 Diagnosing the Cause of Blue Eyes in Dogs

Why are my dog's eyes turning blue and cloudy

When your dog’s eyes start turning blue, identifying the underlying cause becomes paramount. Proper diagnosis is essential to determine the appropriate treatment and ensure your dog’s eye health. Here’s how veterinarians diagnose the reasons behind blue eyes in dogs:

Veterinary Examination

The first step in diagnosing why your dog’s eyes are turning blue involves a comprehensive veterinary examination. During this examination, the veterinarian will:

  • Inspect the Eyes: The veterinarian will visually examine your dog’s eyes to assess the color, clarity, and any visible abnormalities such as cloudiness or inflammation.
  • Evaluate Symptoms: They will review any symptoms your dog may be experiencing, such as changes in behavior, discomfort, squinting, or discharge from the eyes.
  • Discuss Medical History: Gathering information about your dog’s medical history, including previous eye conditions, injuries, or systemic health issues, helps provide context for the current symptoms.

Diagnostic Tests

Depending on the findings from the initial examination, the veterinarian may recommend additional diagnostic tests to pinpoint the cause of your dog’s blue eyes:

  1. Eye Examination:
    • Slit-Lamp Biomicroscopy: This specialized tool allows for a detailed examination of the eye’s structures, including the cornea, lens, and retina, to detect abnormalities like cataracts or corneal dystrophy.
  2. Intraocular Pressure Measurement:
    • Tonometry: This test measures the pressure within the eye, which is crucial for diagnosing conditions such as glaucoma.
  3. Blood Tests:
    • Complete Blood Count (CBC) and Biochemical Profile: These tests help evaluate overall health and screen for systemic conditions that could affect the eyes, such as diabetes or infections.
  4. Diagnostic Imaging:
    • Ultrasound: Ultrasound imaging may be used to examine the internal structures of the eye and detect abnormalities not visible during a routine examination.
  5. Microscopic Evaluation:
    • Cytology or Culture: If an infection is suspected, samples from the eye may be collected and examined under a microscope or cultured to identify the causative organism.

 Treatment Options for Blue and Cloudy Eyes

Discovering why your dog’s eyes are turning blue is just the first step. Once a diagnosis is made, treatment options can vary depending on the underlying condition. Here are some effective approaches veterinarians use to manage blue and cloudy eyes in dogs:

1. Medication

Medication plays a crucial role in treating various eye conditions that cause blue and cloudy eyes in dogs. The specific type of medication prescribed will depend on the diagnosed condition:

  • Anti-inflammatory and Pressure-Relief Options:
  • Steroid Eye Drops: These help reduce inflammation associated with conditions like uveitis or severe allergies.
  • Glaucoma Medications: Medications such as dorzolamide or latanoprost can lower intraocular pressure to alleviate symptoms of glaucoma.
  • Specific Treatments for Infections:
  • Antibiotics: Prescribed to treat bacterial, viral, or fungal infections that may be causing cloudiness in the eyes.

2. Surgery

In some cases, surgical intervention may be necessary to correct or alleviate the underlying cause of your dog’s blue and cloudy eyes:

  • Cataract Removal:
  • Phacoemulsification: A common surgical technique used to remove cataracts and restore vision.
  • Lens Replacement: In cases where the lens is removed due to cataracts, artificial lens implants may be considered.
  • Procedures to Alleviate Glaucoma:
  • Laser Surgery (Laser Cyclophotocoagulation): This procedure aims to reduce intraocular pressure by targeting the ciliary body responsible for fluid production.
  • Traditional Surgery (Trabeculectomy): Involves creating a new drainage channel to decrease fluid buildup and relieve pressure.

3. Managing Chronic Conditions

For chronic conditions that contribute to blue and cloudy eyes, long-term management strategies are essential to maintain your dog’s eye health:

  • Nuclear Sclerosis:
    • Although there is no cure, regular monitoring of vision and adaptation to low-light environments can help manage this age-related condition.
  • Uveitis and Other Chronic Inflammatory Conditions:
    • Ongoing treatment with anti-inflammatory medications or immune-suppressive therapy may be necessary to control inflammation and preserve vision.
