As a pet owner, noticing changes in your dog's health can be concerning. When your dog's blind eye starts turning red, it can be especially alarming. Understanding the underlying causes and appropriate actions to take is crucial for your pet's well-being.

On this page, we will explore the possible reasons for this condition, how to recognize symptoms, when to seek veterinary care, and preventive measures to ensure your dog's health (such as dog halo).

Common Causes of a Red Blind Eye in Dogs

Several factors can cause a blind eye in dogs to turn red. It's essential to identify the root cause to provide the right treatment. Common causes include:

Infections and Inflammation

Infections and inflammation are leading causes of redness in a dog's eye. Bacterial, viral, or fungal infections can affect the eye, leading to redness, swelling, and discomfort. Conjunctivitis, also known as pink eye, is a common infection that can cause redness.


Glaucoma is a condition characterized by increased pressure within the eye, which can cause redness, pain, and vision loss. In dogs with an already blind eye, glaucoma can still develop and exacerbate the redness.

Trauma and Injury

Trauma or injury to the blind eye can result in redness and irritation. Even minor injuries can lead to significant inflammation and discomfort. Dogs can accidentally scratch their eyes or bump into objects, causing damage.


Uveitis is inflammation of the uvea, the middle layer of the eye. This condition can cause redness, pain, and sensitivity to light. Uveitis can result from infections, immune-mediated diseases, or trauma.

Corneal Ulcers

Corneal ulcers are open sores on the cornea, the clear front part of the eye. They can be caused by trauma, infections, or foreign objects in the eye. Ulcers can lead to redness, discharge, and significant discomfort.

Recognizing Symptoms and Signs

Identifying symptoms early can help in managing the condition effectively. Look out for the following signs:

Redness and Swelling

Redness is the most obvious symptom, but swelling around the eye may also be present. Swelling can indicate infection, inflammation, or injury.

Discharge and Tearing

Excessive tearing and discharge from the eye are common signs of infection or irritation. The discharge can be clear, yellow, or green, indicating different types of infections.

Pawing or Rubbing the Eye

If your dog is frequently pawing or rubbing their eye, it suggests discomfort or pain. This behavior can worsen the condition and should be addressed promptly.

Behavioral Changes

Changes in your dog's behavior, such as increased irritability, lethargy, or reluctance to be touched around the eye, can indicate pain or discomfort.

Sensitivity to Light

Sensitivity to light, also known as photophobia, is a common symptom in conditions like uveitis and corneal ulcers. Your dog may squint or avoid bright areas.

When to Seek Veterinary Care for a Red Blind Eye

While some minor eye issues can be managed at home, it's essential to know when to seek professional help. Here are scenarios that require veterinary attention:

Persistent Redness

If the redness persists for more than a day or two, it's crucial to consult a veterinarian. Persistent redness can indicate a serious underlying issue that needs treatment.

Severe Discharge

Heavy or colored discharge from the eye is a sign of infection or a severe condition that requires medical attention.

Visible Injury or Foreign Object

If you notice any visible injury or a foreign object in your dog's eye, do not attempt to remove it yourself. Seek veterinary care immediately to prevent further damage.

Behavioral Changes

Significant changes in your dog's behavior, such as extreme pain, irritability, or lethargy, warrant a visit to the veterinarian. These changes can indicate severe discomfort or pain.

Worsening Symptoms

If symptoms worsen despite home care, it's time to consult a veterinarian. Early intervention can prevent complications and improve your dog's prognosis.

Treatment Options and Home Care

Once you identify the cause, appropriate treatment can be administered. Treatments vary depending on the underlying issue:


Antibiotics, antifungal, or antiviral medications may be prescribed for infections. Anti-inflammatory drugs can help reduce swelling and pain. Always follow the veterinarian's instructions regarding medication.

Eye Drops and Ointments

Eye drops and ointments can provide relief from symptoms and help treat infections. Your veterinarian will recommend the appropriate type based on the condition.

Warm Compresses

Applying a warm compress to the affected eye can help reduce swelling and provide comfort. Use a clean cloth soaked in warm water and gently place it over the eye for a few minutes.

Preventing Further Injury

Ensure your dog does not scratch or rub their eye. You may need to use an Elizabethan collar (cone) to prevent them from causing further damage.

Preventive Measures for Eye Health

Preventing eye issues in dogs involves regular care and monitoring. Here are some preventive measures to keep your dog's eyes healthy:

Regular Veterinary Check-Ups

Routine veterinary check-ups can help detect eye problems early. Regular examinations allow for timely intervention and treatment.

Eye Hygiene

Keep your dog's eyes clean by wiping away discharge and debris with a damp cloth. Be gentle to avoid causing irritation.
