If you’ve ever noticed your dog squinting or dealing with constant eye discharge, it could be more than just irritation.
Dry eye, medically known as Keratoconjunctivitis sicca, is a common yet often overlooked condition in dogs that results from insufficient lubrication of the eye. Under normal circumstances, tears are produced by specialized glands—primarily the lacrimal glands and the glands of the third eyelid—to keep the surface of the eye moist, nourished, and protected from debris and infection. These tears form a vital protective film that maintains clarity of vision and overall eye health.
In dogs with dry eyes, this natural process is disrupted. The tear-producing glands fail to function properly, leading to inadequate tear production or poor-quality tears that evaporate too quickly. As a result, the surface of the eye becomes dry, irritated, and inflamed. Without enough lubrication, blinking can become painful, and the eye is more vulnerable to damage, infection, and even long-term complications such as corneal ulcers or scarring.
Although it may start as mild irritation, dry eye can quickly progress if left untreated. Dogs affected by this condition often experience discomfort that can significantly impact their quality of life, making early recognition and proper management essential.
Symptoms:
-
Signs of dullness to the surface of the eye.
-
Eye redness (a definite sign of inflammation).
-
Thick, stringy discharge will surface that’s hard to clean away.
-
Squinting the affected eye(s) and reluctance to blink.
-
In some cases, the nostril on the same side is also affected, and the dog will repeatedly lick his nose to keep it moist.
Causes of Dry Eyes in Dogs
-
Immune system disorders (most common)
-
Certain medications
-
Eye injuries or trauma
-
Breed predisposition (i.e. Yorkshire Terriers, Bulldogs, Cocker Spaniels, Shih Tzus)
-
Aging
Natural and home remedies for dry eye in dogs focus on two main goals: reducing inflammation and increasing lubrication of the eye. While these remedies may not cure the condition entirely—especially in chronic cases—they can play a valuable role in managing symptoms, improving comfort, and supporting overall eye health when used consistently.
There are several simple things you can do at home to help manage your dog’s symptoms.
Home Remedies
1. Warm Compress. Applying a clean, warm compress to your dog’s eyes can help stimulate tear production and loosen crusty discharge. Hold it gently over the eye for a few minutes, 1-2 times daily.
2. Gentle Eye Cleaning. Use a soft cloth or sterile cotton pad with saline solution to wipe away discharge. Always wipe from the inner corner outward to avoid spreading debris into the eye.
3. Artificial Tears (Lubricating Drops). Over the counter artificial tear solutions can help keep the eye moist. Choose preservative-free options and apply as directed.
4. Coconut Oil (External Use Only). A very small amount applied around (not in) the eye area may help soothe irritated skin and reduce inflammation.
5. Humidifier Use. Dry indoor air can worsen symptoms. Using a humidifier helps maintain moisture in the environment, especially during colder months.
6. Omega-3 Fatty Acids. Adding omega-3 supplements (like fish oil) to your dog’s diet may support tear production and reduce inflammation over time.
While home care can help, some cases require medical treatment. If you notice symptoms persist or worsen, if the eye develops ulcers, or you notice excessive pain or behavioral changes, it’s important to visit your veterinarian. Veterinarians use the Schirmer Tear Test (STT) to diagnose dry eye syndrome and measure aqueous tear production in dogs. This is a simple, painless test involving a strip of special paper placed in the lower eyelid.
In many cases, veterinarians will prescribe medications such as Cyclosporine or Tacrolimus, which will work by reducing inflammation in the tear glands and helping them produce tears more effectively. These are often used long-term and can make a big difference in your dog’s comfort when used consistently. Along with tear stimulants, your vet may also recommend medicated lubricating drops or gels that provide longer-lasting moisture than over the counter options.
Managing dry eye in dogs is usually an ongoing process rather than a one-time treatment. Many dogs will require daily eye drops for the rest of their lives to keep symptoms under control. With early detection, proper care, and a combination of home remedies and veterinary support, dogs with dry eyes can live happy, comfortable lives without constant irritation or pain.
Staying consistent with treatment and paying attention to early signs can make all the difference. If you notice any changes in your dog’s eyes, addressing them early can help prevent more serious complications down the road.
