What to Do When Your Dog Is Squinting: Understanding the Causes and Solutions

If you’ve noticed your dog squinting more than usual, it could be a sign that something is wrong. While occasional squinting may not be serious, persistent or severe squinting often indicates an underlying eye condition that requires attention. In this article, we’ll explore the possible reasons behind your dog’s squinting, how to evaluate the symptoms, and what steps you should take to protect your dog’s vision and health.

Common Reasons Why Dogs Squint

Dogs squint for various reasons, some of which are minor, while others may be serious. Below are the most common causes:

Foreign objects: Dust, dirt, or grass particles can irritate the eye, causing a dog to squint and paw at the area.
Eye infections: Bacterial, viral, or fungal infections can make the eye inflamed and painful.
Corneal ulcers: Damage to the cornea, often caused by trauma or infection, can be extremely painful and lead to squinting.
Dry eye (Keratoconjunctivitis Sicca): A chronic condition where the eye fails to produce enough tears, leading to irritation and squinting.
Glaucoma: Increased pressure in the eye can cause severe pain and vision loss. Squinting may be an early symptom.
Uveitis: Inflammation of the inner eye tissues that causes discomfort and squinting.
Allergic reactions: Environmental allergens can cause itchiness and watery eyes, leading to squinting.
Injury or trauma: Blunt force, scratches, or bites near the eye area can result in squinting and discomfort.

Symptoms to Watch For

Squinting itself is often accompanied by other signs indicating your dog might be in discomfort:

Excessive tearing or discharge
Redness or swelling of the eye or eyelid
Your dog keeping the eye shut for a prolonged period
Pawing at or rubbing the eye
Cloudiness or visible change in the eye structure
Aversion to light (photophobia)
Noticeable behavioral changes like hiding or lack of interest in play

If you observe one or more of these signs in addition to squinting, prompt action is necessary.

First Steps Owners Should Take

When you notice your dog squinting, follow these immediate steps:

Inspect the eye: Use a clean, calm environment and good lighting. Gently lift the lid to check for debris, swelling, or visible damage.
Do not touch or flush the eye aggressively: Avoid using human eye drops or medications unless directed by a vet.
Prevent further injury: Use an Elizabethan collar (e-collar) if needed to keep the dog from scratching or rubbing the eye.
Schedule a veterinary appointment: If signs persist after a few hours or worsen, it’s vital to consult your veterinarian.

How Vets Diagnose the Problem

Veterinarians may use several methods to identify what’s causing your dog to squint:

Fluorescein staining: To detect corneal ulcers by applying a special dye that lights up damaged areas.
Tear production tests: To diagnose dry eye.
Tonometry: Measures intraocular pressure to check for glaucoma.
Ophthalmic exams: Using specialized tools for a comprehensive view of eye structures.

Treatment Options

The treatment depends entirely on the diagnosis:

Removing foreign objects: In minor cases, debris may be flushed out under vet supervision.
Medication: Includes antibiotic, antifungal, or anti-inflammatory eye drops or ointments.
Lubricating eye drops: For dogs diagnosed with dry eye.
Surgery: Required in severe cases such as corneal perforation or advanced glaucoma.

When to Seek Emergency Help

Seek immediate veterinary care if:

Your dog is in visible pain or distress
The eye appears red, swollen, or bleeding
There is thick or greenish discharge
Your dog keeps the eye completely closed for more than a few minutes
There are signs of trauma or obvious injury

Preventive Measures

You can help prevent many eye issues by:

Keeping your dog’s face clean and free from debris
Trimming hair around the eyes regularly
Protecting your dog from harsh winds or dusty environments
Monitoring for allergies and seasonal irritants
Getting routine veterinary checkups

Conclusion

Squinting in dogs is often a sign of discomfort or an underlying health problem. While minor causes like dust may be harmless, persistent or severe symptoms require professional diagnosis and treatment. Acting quickly can protect your dog’s vision and improve their quality of life. Always consult with a veterinarian if you’re uncertain—your dog depends on your attentive care.
