Quick Summary of Eye Infections in Dogs
- Eye infections in dogs can appear suddenly and often worsen fast, especially if caused by scratches, debris, bacteria, or allergies.
- Watch for early signs like redness, squinting, tearing, pawing at the face, or yellow/green discharge — these usually require a vet visit.
- Allergies typically cause clear discharge in both eyes, while infections often affect one eye and produce thick or coloured mucus.
- Treatment must come from a veterinarian; at-home care can support comfort but won’t clear an infection.
- Prevent infections by keeping the eye area clean, avoiding irritants like wind and debris, and choosing supervised environments like DogPlay where staff notice early symptoms quickly.
Eye issues can show up out of nowhere — one minute your dog looks totally fine, and the next they’re blinking hard, squinting, or dealing with a goopy eye that wasn’t there an hour ago. The reality is that eye infections in dogs can happen for many reasons: a tiny scratch from play, sand from a windy walk, bacteria, allergies, or even low tear production that leaves the eye unprotected. And because eye problems can worsen fast, recognizing early signs is the best way to protect your dog’s comfort and vision.
Living in Vancouver adds its own challenges: forest trails, ocean wind, pollen spikes, and rainy-day debris all increase the chance of irritation. Knowing the difference between harmless tearing and symptoms that need a vet visit helps you stay calm and act quickly.
When you’re busy, it helps knowing someone’s closely paying attention to your dog, especially when those early symptoms are easy to miss at home. At DogPlay, we notice those small changes during daycare, grooming, and boarding — extra blinking, face rubbing, avoiding play, or a pup who just isn’t acting like themselves — and we know how to support them when something’s bothering them. We work with so many dogs every day that these subtle shifts stand out right away, and we’ll reach out fast so you can get your pup the care they need. If that kind of attention gives you peace of mind, you can register and schedule a Trial Day.
What Are the Early Signs of Eye Infections in Dogs?
The sooner you recognize the symptoms of eye infections in dogs, the easier it is to prevent complications. Early signs often start small: a bit of redness, watery eyes, or increased blinking. But infections can progress quickly, so understanding what to watch for matters.
Look for cloudiness, excessive tearing, or squinting. A dog that keeps one eye closed, paws at their face, or suddenly avoids bright light is showing clear discomfort. Thick yellow or green discharge is one of the biggest indicators of a bacterial eye infection in dogs. Other symptoms include swelling around the eyelids, redness in the whites of the eyes (the sclera), or irritation around the inner corner.
At DogPlay, our team watches for these subtle changes during play, grooming, and rest times, especially after outdoor activities. If we notice irritation, we’ll separate your dog, keep them comfortable, and call you right away so you can consult your vet.
What Causes Eye Infections in Dogs?
Dogs can develop eye infections for all kinds of reasons, but most of them trace back to a few common causes. The most common cause is physical irritation or injury: sand, dust, debris, or even a playful paw swipe can scratch the cornea. That tiny scratch then creates an opening for bacteria to enter, causing infection.
Environmental triggers play a big role in Vancouver. Forest trails, windy beaches, pollen, and mud increase the chance of debris irritating your dog’s eyes. Dogs with prominent eyes, such as pugs, bulldogs, and shih tzus, are especially vulnerable because their eyes are more exposed.
Dry eye (keratoconjunctivitis sicca), allergies, and eyelid infections — which can develop from trapped debris, bacteria, or irritation along the lash line — can also lead to some of the most common eye infections in dogs.
Dogs who stick their head out car windows are at higher risk for foreign bodies hitting the eye. And shampoo or grooming products that get into the eye can irritate the surface and lead to infection if not flushed properly.
Facilities like DogPlay help reduce trauma-based infections by supervising dogs closely and maintaining a safe, clean indoor environment that minimizes rough collisions or accidental scratches.
Differentiating Eye Allergies vs. Eye Infection in Dogs
Owners often confuse allergies with an eye infection, which makes sense — the symptoms overlap. Allergies usually produce clear, watery discharge and redness around the eyelids. The eyes may look irritated, but symptoms often affect both eyes equally because the cause is systemic (like pollen, dust, or mold).
In contrast, infections often show up in just one eye. They produce thicker, stickier discharge, more pronounced swelling, and behaviours like squinting or keeping the eye partially shut. Viral infections may start watery but quickly turn to coloured discharge.
A major differentiator is the speed of escalation. Allergies cause irritation, but infections cause pain. If your dog starts rubbing their face, avoiding light, or producing yellow or green discharge, it’s more likely a conjunctivitis eye infection — meaning the lining around the eye is inflamed and often infected — rather than allergies.
Regular grooming at DogPlay helps reduce irritation by keeping the fur around the eyes clean and trimmed, a simple step that prevents allergens from collecting around the face.
Dog Eye Infection Treatment Options
Getting proper dog eye infection treatment requires a visit to a veterinarian because different causes need different treatments. Vets may run a tear test, stain the cornea to detect scratches, or measure eye pressure to rule out more serious conditions. This ensures your dog receives the correct medication.
Bacterial infections are treated with prescription antibiotic drops or ointments. Viral infections may require antiviral medications, lubricating drops, or supportive care. Dry eye requires long-term tear stimulants. Eyelid infections often need oral antibiotics and anti-inflammatory medication.
If you’re wondering how to get rid of an eye infection in dogs, the most effective and safest option is using the medication your vet prescribes for the full recommended duration.
Can You Treat a Dog’s Eye Infection at Home?
Owners frequently search for a home remedy for dog eye infection, but infections progress quickly and should be treated professionally. You can provide supportive care at home while waiting for your vet appointment, but treatment itself must come from a veterinarian.
Safe at-home steps include using a warm compress to remove debris and soothe irritation or rinsing with sterile saline. At DogPlay, we keep sterile saline eye wash on hand so we can gently flush out any dust or debris when we notice irritation starting, before it becomes more uncomfortable for your pup. We’ll always call you right away if anything looks concerning. Keeping your dog from rubbing their eye, with a cone if necessary, prevents worsening damage. But human eye drops, old medications, herbal rinses, or DIY solutions can make the problem worse.
And just a quick reminder: dogs showing eye infection symptoms should stay home from daycare until your vet gives the all-clear. If your pup normally attends our dog day care in Vancouver, keeping them home for a day or two prevents irritation from play, debris, or face-rubbing, and it keeps other dogs safe, too.
How to Prevent Eye Infections in Dogs
Prevention focuses on minimizing irritation, trauma, and exposure to debris. After walks or hikes, especially in Vancouver’s forests and beaches, gently wipe around your dog’s eyes to remove pollen, sand, or mud. Keeping facial fur trimmed prevents hair from poking the eye and reduces the risk of irritation.
Avoid letting your dog hang their head out the car window, especially on windy days, when dust, sand, and flying debris can easily irritate or scratch their eyes.
Supervised environments like DogPlay help prevent accidental scratches during group play, and regular grooming keeps the eye area clean. If your dog boards frequently while you travel, our 24/7 team can keep a close watch on eye health throughout their stay.
Common Questions About Eye Infections in Dogs
Can a Dog’s Eye Infection Heal on Its Own?
Do eye infections in dogs go away on their own? No — they usually worsen without proper medication, especially if the cornea is scratched. Ulcers can form within 24–48 hours and may lead to long-term vision problems if untreated. Any coloured discharge, intense squinting, or sudden swelling should be assessed by a vet as soon as possible.
What Is the Most Common Eye Infection in Dogs?
The most commonly diagnosed eye infection in dogs is conjunctivitis, which can be caused by bacteria, viruses, or allergies. Bacterial conjunctivitis often develops after scratches or debris irritation, while allergic conjunctivitis appears during pollen-heavy seasons. Dogs with prominent eyes or long fur near the face tend to develop infections more frequently.
When Should I Be Concerned About My Dog’s Eye Discharge?
Some tearing is totally normal, but coloured or sticky discharge is a red flag. Thick green or yellow mucus usually points to an eye infection, especially if your dog is squinting or avoiding light. If they wake up with crusty eyes, blink more than usual, or keep one eye shut, reach out to your vet.
