Corneal Issues

One cause of white spots on a dog’s eye is lipid accumulation, called corneal lipidosis or lipid keratopathy. This issue occurs when lipids, composed of cholesterol and other chemical compounds, build up on the dog’s cornea. Factors that contribute to this condition include genetics, high cholesterol levels, and hypothyroidism.

Another corneal issue is infectious keratitis, which involves inflammation of the cornea. This can cause white spots on your dog’s eye, so it’s crucial to address this issue promptly to protect your pet’s vision.


Glaucoma is a condition that causes increased pressure in the eye, leading to potential vision loss. It can be primary or secondary, depending on its origins. Primary glaucoma is inherited and generally affects both eyes, while secondary glaucoma results from other eye issues, such as inflammation or tumors. Both types can cause white spots on the eye and should be addressed as soon as possible.


Cataracts cause the lens of your dog’s eye to become opaque, often appearing as a white spot. Early detection is essential, as untreated cataracts can lead to blindness in dogs. If your pet is diagnosed with cataracts, your veterinarian can provide treatment options to maintain their vision.

Pigmentary Keratitis

Pigmentary keratitis is another potential cause of white spots on a dog’s eye. In this condition, the cornea becomes inflamed, and dark pigment accumulates over time, which can eventually lead to blindness. Look for dark spots on your pet’s cornea, and contact your veterinarian if you suspect pigmentary keratitis.

Ocular Melanoma

Ocular melanoma is a type of melanoma in dogs that affects the eye. This tumor can cause a white spot on the dog’s eye and may eventually lead to vision loss. If you notice any changes in your dog’s eye, consult your veterinarian immediately for a thorough examination.

In conclusion, various issues may cause white spots on your dog’s eye, but acting quickly and consulting with a professional can help protect your pet’s sight.

Symptoms and Indications

Red Eye

We may notice our dog’s eye turning red, which can be caused by various factors. Red eyes can be a symptom of inflammation or infection like uveitis. We must monitor our dog’s condition and consult a veterinarian if the redness persists or worsens.

Eye Discharge and Boogers

Eye discharge, or boogers, is another common symptom we might observe in our dogs. While eye boogers can be expected, excessive discharge or mucus could indicate an underlying issue, such as an eye infection. The mucus often appears as a white or yellowish film that moves when the dog blinks. We should monitor our dog’s eye health and consult a veterinarian if the discharge becomes abnormal.

Eye Discomfort and Irritation

Signs of eye discomfort and irritations in our dogs may include squinting, rubbing, and excessive tearing. These symptoms can be caused by various factors, such as corneal ulcers, irritants, or trauma to the eye. If our dog shows symptoms, seeking veterinary advice and proper treatment is essential to ensure their eye health.


When we notice a white spot on our dog’s eye, it’s essential to get a proper diagnosis from a veterinarian. Several conditions can cause white spots, and accurate diagnosis will ensure appropriate treatment and care for our furry friend. This section discusses some common conditions and tests related to white spots on a dog’s eye.

Conjunctivitis and Dry Eye

Conjunctivitis, or inflammation of the conjunctiva, can cause white or grayish mucus to accumulate on the eye’s surface, leading to a white spot appearance. Similarly, dry eye (keratoconjunctivitis sicca), an autoimmune condition that attacks tear-producing glands, can cause white-gray mucus. It’s essential to consult with a veterinarian for proper assessment and treatment in both cases.

Uveitis and Retinal Issues

Inflammation of the uvea, known as uveitis, can also cause white spots on a dog’s eye. Uveitis can affect dogs of any age, and it’s crucial to determine the cause to provide the appropriate treatment. Additionally, retinal issues like retinal detachment or degeneration may lead to white spot formation in the eye. A comprehensive examination by a veterinarian will help identify the underlying problem and determine the best course of action.

Schirmer Tear Test and Tear Production

To accurately diagnose conditions like dry eye, veterinarians often use a diagnostic tool called the Schirmer Tear Test. This test measures tear production by placing a special strip of paper under the lower eyelid for a specific duration. The strip absorbs tears and indicates their production level. Abnormal tear production often leads to white or opaque spots on a dog’s eye, so a Schirmer Tear Test can provide valuable information for diagnosis and treatment planning.

Treatment Options


In some cases, a veterinary ophthalmologist may recommend surgery as a treatment option for white spots on a dog’s eye. Surgery can effectively address specific underlying causes, such as corneal ulcers or eye injuries. Discussing the potential risks and benefits with the veterinarian before proceeding with this option is crucial.

Artificial Tears

For less severe cases, or if the white spot is caused by a less serious condition, we can recommend using artificial tears to provide relief for the dog. Artificial tears help keep the eye moist, alleviate irritation, and can aid in the healing process.

Eye Infection Medications

If a veterinarian determines that the white spot is due to an eye infection, they will likely prescribe eye infection medications to treat the issue. These medications can include antibiotic eye drops or ointments, which should always be administered as directed by the veterinarian.

Eyelid Abnormalities and Intraocular Pressure

Some white spots on a dog’s eye can be related to eyelid abnormalities or issues with intraocular pressure. In these cases, addressing the underlying eyelid problem or regulating the pressure within the eye can help alleviate the white spot and prevent further complications.

Preventing Blindness

One of our primary concerns when dealing with white spots on a dog’s eye is to prevent further damage and potential blindness. To achieve this, it’s essential to closely monitor the dog’s condition and adhere to the veterinarian’s treatment recommendations. This may involve routine check-ups, proper administration of medications, and regular at-home eye care.
