Understanding Why Your Dog is Scratching Their Eyes

Free Subscribtion

As a dog owner, it’s essential to pay attention to any unusual behavior or signs of discomfort in your furry friend. One common issue that dogs may experience is scratching their eyes. It can be concerning to see your dog pawing at their eyes or rubbing their face on the floor, but there are several reasons why this behavior may occur. In this comprehensive guide, we will explore the various causes of eye itching in dogs, potential treatments, and when to seek veterinary assistance.

Common Causes of Eye Itching in Dogs

Allergies and Irritation

Just like humans, dogs can suffer from allergies. Seasonal allergies, contact irritants, food allergies, and reactions to pollen or airborne irritants can all lead to eye itching in dogs. These allergies can cause your dog’s eyes to become itchy, watery, and red. You may also notice your dog pawing at their eyes or rubbing their face on the floor in an attempt to alleviate the itchiness. Environmental factors such as pollen, mold, dust mites, and even certain cleaning products can trigger allergic reactions in dogs.

Canine Conjunctivitis

Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva, the thin membrane that covers the front of the eye and lines the inner surface of the eyelids. If your dog has conjunctivitis, you may observe discharge from the eye, redness, swelling, and squinting. It is crucial to seek veterinary attention if you notice these symptoms, as conjunctivitis can be secondary to a more serious underlying issue.

Inflammation and Uveitis

Inflammation in the middle layer of the eye, known as uveitis, can cause discomfort and eye irritation in dogs. Symptoms of uveitis may include excessive blinking, squinting, tearing, and redness. In some cases, uveitis can be associated with conditions like glaucoma, which is an increase in eye pressure. If you suspect your dog has uveitis, it is important to have them evaluated by a veterinarian.

Dry Eye and Keratoconjunctivitis Sicca (KCS)

Dry eye, also known as keratoconjunctivitis sicca (KCS), occurs when a dog’s tear glands do not produce enough tears to lubricate the eyes adequately. This condition can result in corneal irritation and discomfort. Dogs with KCS may experience excessive blinking, squinting, and holding their eyes closed. Certain immune disorders, infections, or medications can contribute to the development of KCS in dogs. Treatment for KCS typically involves the use of eye drops to improve tear production and provide lubrication.


Entropion is a condition in which the eyelid rolls inward, causing the eyelashes to rub against the surface of the eye. Breeds with loose facial skin, such as Bulldogs, Pekingese, and Shar Peis, are more prone to developing entropion. This condition can lead to redness, swelling, and watery eyes. Surgical correction is often necessary to prevent further damage to the cornea and alleviate the discomfort caused by entropion.

Diagnosing and Treating Eye Irritation in Dogs

If you suspect that your dog is experiencing eye irritation or itching, it is essential to consult with your veterinarian for a proper diagnosis and treatment plan. The veterinarian will perform a thorough examination of your dog’s eyes and may conduct additional tests to determine the underlying cause of the itching.

Examination and Evaluation

During the examination, your veterinarian may use a special dye called fluorescein to assess the extent of any corneal injuries or ulcers. This dye adheres to damaged corneal cells, allowing the veterinarian to determine the depth and severity of the injury. Additionally, they may measure tear production, check for foreign bodies, and evaluate the overall health of the eye.

Treatment Options

Treatment for eye itching in dogs will depend on the underlying cause and severity of the condition. In many cases, minor corneal injuries and irritations can be treated with antibiotic eye drops and pain medication. These medications help prevent infection and promote healing. Additionally, your veterinarian may recommend flushing the eye with a sterile saline solution to remove any foreign objects or irritants.

For more severe conditions like uveitis or corneal ulcers, your veterinarian may prescribe additional medications such as anti-inflammatory drugs or oral antibiotics. In some cases, surgery may be necessary to correct conditions like entropion or to promote healing in cases of severe corneal ulcers.

Preventing Eye Irritation in Dogs

While it may not always be possible to prevent eye irritation in dogs, there are some steps you can take to minimize the risk:

  1. Keep your dog’s living environment clean and free from potential allergens such as dust, mold, and pollen.
  2. Avoid exposing your dog to cigarette smoke or other irritants.
  3. Use gentle and pet-safe cleaning products when washing your dog’s bedding and other items they come into contact with.
  4. Regularly inspect your dog’s eyes for any signs of redness, discharge, or discomfort.
  5. Trim the hair around your dog’s eyes to prevent it from irritating their eyes.
  6. Take precautions during outdoor activities, such as using protective goggles or avoiding areas with dense vegetation.

When to Seek Veterinary Assistance

If your dog is experiencing persistent eye itching, redness, swelling, discharge, or any other concerning symptoms, it is crucial to seek veterinary assistance promptly. Your veterinarian will be able to provide an accurate diagnosis and develop an appropriate treatment plan to alleviate your dog’s discomfort and prevent any potential complications.

Remember, the health and well-being of your furry companion should always be a priority, and seeking professional veterinary care is the best course of action when it comes to eye issues or any other health concerns your dog may have.

In conclusion, eye itching in dogs can be caused by various factors such as allergies, conjunctivitis, inflammation, dry eye, entropion, or corneal ulcers. Proper diagnosis by a veterinarian is essential to determine the underlying cause and provide appropriate treatment. By understanding the potential causes and taking preventive measures, you can help keep your dog’s eyes healthy and free from irritation. Remember, if you notice any signs of eye discomfort in your dog, don’t hesitate to seek veterinary assistance to ensure their well-being.
